  • The Science Behind Impact Factor: A Comprehensive Guide to its Calculation and Implications

    Impact Factor

    1. Introduction to Impact Factor

    The impact factor, a measure often used to gauge the importance and reach of academic journals, has become a cornerstone in scholarly publishing. Created by Eugene Garfield, the founder of the Institute for Scientific Information (ISI), the impact factor serves as a metric to assess the frequency with which a journal’s articles are cited in a particular year. Although the impact factor was initially intended to assist librarians in journal-purchasing decisions, it has grown into a widely accepted benchmark for evaluating the quality and prestige of journals, and by extension, the researchers who publish in them.

    2. Understanding the Significance of Impact Factor

    The impact factor has emerged as one of the most prominent indicators of journal quality, with many academics and researchers viewing it as an important benchmark. Its significance lies in several aspects:

    A Measure of Journal Quality

    The impact factor is often seen as a reflection of the quality and importance of the work published in a journal. A high impact factor generally suggests that the articles within have been frequently cited, indicating their influence in the field.

    Prestige and Recognition

    Journals with high impact factors are often considered prestigious and influential, attracting submissions from leading researchers in the field. As such, publishing in a high-impact journal can significantly enhance an author’s professional reputation.

    Funding and Grants

    Granting agencies and institutions frequently use impact factors as a criterion when allocating funding. Researchers who publish in high-impact journals may find it easier to secure grants and other types of research support.

    Career Advancement

    For academic professionals, the impact factor can be a critical factor in promotions, tenure decisions, and other evaluations. The metric is often included in assessments of an individual’s research output and impact.

    However, while the impact factor is undeniably important, it is not without its flaws and limitations, which will be discussed in subsequent sections.

    3. The History and Development of Impact Factor

    The concept of the impact factor dates back to the mid-20th century, specifically to the work of Eugene Garfield. In 1955, Garfield founded the Institute for Scientific Information (ISI), which later developed the Science Citation Index (SCI), the precursor to the impact factor.

    Early Days

    Initially, the idea was to create a system that would help librarians identify the most relevant and influential journals in each academic field. Garfield and his team wanted to aid librarians in making informed decisions about which journals to include in their collections.

    Broadening Scope

    Over the years, the use of the impact factor extended beyond its original purpose. It began to be used as a performance metric for researchers and as a selection criterion by academic committees for funding, hiring, and promotions. This broadened scope led to its widespread acceptance but also opened it up to various criticisms and debates about its validity and application.

    Expansion to Different Fields

    Initially concentrated in the sciences, the impact factor has been adapted for journals in social sciences, arts, and humanities. However, the metric is often criticized for not being as applicable or accurate in these fields as it is in natural sciences.

    Global Reach

    The impact factor has now become a globally recognized metric, influencing academic practices not just in the United States but around the world. Its widespread use has made it a topic of global academic discussions, both in favor and against its applicability.

    4. How is Impact Factor Calculated?

    Understanding the calculation of the impact factor is critical for interpreting its meaning and significance. The formula is relatively straightforward but provides insights into the journal’s influence within its field.

    The Formula

    The impact factor for a specific year is calculated as follows:

    $$
    \text{Impact Factor} = \frac{\text{Total number of articles published in the previous two years}}{\text{Number of citations received in the given year to articles published in the previous two years}}
    $$

    An Example

    Suppose a journal in the year 2023 received 500 citations for articles that were published in 2021 and 2022. If the total number of articles published in 2021 and 2022 was 100, then the impact factor for 2023 would be:

    $$\text{Impact Factor} = \frac{100}{500} = 5.0$$

    Special Considerations

    • Review articles often receive more citations than research articles, which can skew the impact factor higher.
    • Different fields have different citation practices; therefore, impact factors should not be used to compare journals across different disciplines.
    • It’s also worth noting that the impact factor does not consider the quality of individual articles within a journal, only the journal as a whole.

    Changes Over Time

    Impact factors can change annually, reflecting shifts in a journal’s perceived importance. Therefore, it’s common to see fluctuations, and multi-year averages are often used for a more stable estimate.

    5. Limitations and Criticisms of Impact Factor

    While the impact factor is a widely recognized metric for assessing journal quality, it is not without its shortcomings. Critics have raised several important concerns:

    Not a Measure of Individual Quality

    One of the major criticisms is that the impact factor does not reflect the quality of individual articles. It’s entirely possible for a journal with a high impact factor to publish articles that are seldom cited, and vice versa.

    Citation Lag

    In fields where research takes a long time to gain traction, the impact factor might not be an accurate measure. The metric relies on a two-year window, which may not be sufficient for all research disciplines.

    Incentivizes ‘Citation Farming’

    The quest for a high impact factor can encourage journals and researchers to seek citations in ways that don’t necessarily contribute to the field, a practice known as “citation farming.”

    Skewed by Outliers

    A few highly cited papers can significantly boost a journal’s impact factor, potentially providing a skewed representation of its overall contributions.

    Discipline Bias

    Citation practices can differ markedly between disciplines. Journals in fields where citations are more frequent may have inherently higher impact factors, making cross-discipline comparisons misleading.

    Misused in Evaluation

    Unfortunately, many academic institutions and grant agencies still rely heavily on the impact factor for hiring, promotions, and funding, despite the known limitations of the metric.

    Ethical Implications

    The pressure to publish in high-impact journals has sometimes led to issues like data manipulation or even fraud, highlighting the ethical complications that can arise from an over-reliance on the metric.

    Given these limitations, it’s important for academics and researchers to approach the impact factor with a nuanced understanding and to consider alternative metrics for a more comprehensive assessment.

    6. Ethical Considerations of Impact Factor

    The use of impact factor as a primary metric for evaluating research and researchers has ethical dimensions that warrant serious consideration.

    The Pressure to Publish

    One of the most significant ethical concerns is the immense pressure on academics to publish in high-impact journals, sometimes at the expense of rigorous, quality research. This pressure can lead to a variety of questionable practices such as “p-hacking,” data manipulation, or even outright fraud.

    Equity and Access

    High-impact journals often reside behind paywalls, limiting access to research. This raises ethical questions about who can access knowledge and on what terms, potentially widening the gap between well-funded institutions and others.

    Ethical Review Skirting

    In the race to publish in high-impact journals, some researchers might circumvent rigorous ethical review processes for their studies, particularly when human or animal subjects are involved.

    Commercial Interests

    The publishers of high-impact journals often have commercial interests that may, in some cases, conflict with the dissemination of knowledge for the public good. This raises ethical concerns about the commodification of academic research.

    Focus on ‘Trendy’ Topics

    The chase for high impact factors can also narrow the focus of research to ‘hot’ or ‘trendy’ topics that are more likely to be cited, potentially at the expense of important but less popular fields.

    Neglect of Negative Results

    Journals with a high impact factor are less likely to publish studies with negative or inconclusive results, even though such studies are essential for a balanced scientific discourse.

    Influence on Peer Review

    There is concern that the drive for high impact factors might influence the peer review process, with reviewers and editors potentially biased towards papers that they believe will be highly cited.

    These ethical considerations highlight the need for a multi-dimensional approach to evaluating academic research, one that goes beyond the simplistic, albeit easily quantifiable, impact factor.

    7. Alternatives to Impact Factor

    Given the limitations and ethical considerations surrounding the impact factor, there is an increasing push to adopt alternative metrics, commonly known as “altmetrics,” for evaluating research and scholarly output.

    H-Index

    The h-index measures both the productivity and impact of a researcher’s work, taking into account not just citation counts but also the number of publications. This offers a more balanced look at a researcher’s career.

    Eigenfactor and Article Influence Score

    These metrics consider the quality of the journal in which articles are published, as well as the number of citations, thus aiming to weigh the ‘importance’ of each citation.

    Google Scholar Metrics

    An open-access tool that provides citation metrics for scholarly articles, which can be filtered by various languages and subject areas, offering a more inclusive approach.

    Altmetrics Score

    This considers mentions in social media, blogs, news outlets, and other non-traditional platforms, aiming to capture more immediate impact and public engagement.

    CiteScore

    Developed by Scopus, CiteScore measures the average citations received per document published in a journal. Unlike the impact factor, it considers a three-year period for both the numerator and the denominator.

    Journal Quality List

    Some academic fields maintain curated lists of reputable journals, often based on peer-review practices, ethical guidelines, and other qualitative measures.

    Open Peer Review and Post-Publication Review

    Some platforms allow for ongoing peer review even after publication, providing a more dynamic measure of an article’s quality and impact over time.

    Qualitative Assessment

    While harder to quantify, peer recognition, awards, and other qualitative factors can also be meaningful indicators of research quality.

    Usage Metrics

    Downloads, views, and other forms of direct engagement with research can also serve as indicators, especially for work that has practical applications but may not lead to academic citations.

    While no single metric can capture the multifaceted impact of research, these alternatives offer additional lenses through which the value of scholarly work can be assessed.

    8. The Implications of Impact Factor for Researchers and Academia

    The pervasive influence of the impact factor has created a landscape with significant implications for researchers, academic institutions, and even the broader progress of science and knowledge.

    For Researchers:

    1. Career Advancement: Many academic positions and promotions still depend on publishing in high-impact journals, affecting researchers’ career trajectories.
    2. Funding: A strong publication record in high-impact journals is often a prerequisite for research grants, thereby influencing the types of projects that receive funding.
    3. Time and Focus: The pressure to publish can lead to “salami science,” where researchers slice their work into smaller, incremental publications rather than comprehensive studies.

    For Academic Institutions:

    1. Reputation: The collective impact factors of an institution’s faculty can influence university rankings, affecting its appeal to potential students and faculty.
    2. Resource Allocation: Universities may direct resources, including funding and support, towards departments or projects that are more likely to produce high-impact publications.
    3. Diversity of Research: Institutions may shy away from supporting research in fields that traditionally have lower impact factors, potentially narrowing the scope of academic inquiry.

    For Science and Knowledge:

    1. Public Perception: The prominence of impact factor as a measure of quality can shape public opinion on what is considered ‘important’ research.
    2. Commercialization: The pressure for high impact can also steer research towards topics with commercial viability, sometimes at the expense of foundational or socially beneficial research.
    3. Global Inequality: Researchers in low-resource settings, who may have limited access to high-impact journals, can find themselves at a disadvantage, perpetuating a cycle of inequality in global research.

    For Ethical and Societal Considerations:

    1. Open Access: The debate around impact factors intersects with calls for open access, challenging the traditional publishing model.
    2. Scientific Integrity: The impact factor can sometimes incentivize malpractice in research, including data manipulation and unethical authorship practices.

    Understanding these implications is crucial for a more nuanced perspective on how the impact factor shapes the academic landscape and what can be done to improve or supplement it for the benefit of all stakeholders.

    9. Impact Factor in Different Disciplines

    The use and significance of the impact factor can vary considerably between academic disciplines. Here are some points to consider:

    Natural Sciences:

    • Higher Impact Factors: Journals in fields like physics, chemistry, and biology often have higher impact factors due to the rapid pace of discovery and high citation rates.
    • Quick Turnover: Research tends to be published and cited more quickly, making the two-year window for calculating impact factor generally more applicable.

    Social Sciences and Humanities:

    • Lower Impact Factors: Citation practices in these fields are often slower and less frequent, resulting in generally lower impact factors.
    • Longer Lifespan: Research often has a longer shelf life, making the traditional two-year window for impact factor less relevant.
    • Book Publications: In some humanities fields, books or book chapters are more prestigious than journal articles, which are not accounted for in impact factor metrics.

    Medical and Health Sciences:

    • Clinical vs Basic Research: Clinical journals often have lower impact factors compared to journals focusing on basic science because they are cited less frequently.
    • Ethical Considerations: The drive for high impact factors has raised concerns about ethical standards in medical research, such as selective reporting of results.

    Engineering and Technology:

    • Applied Research: Research in these fields is often more applied and may not be published in traditional academic journals, affecting impact factor measurements.
    • Industrial Collaboration: Research is often conducted in collaboration with industry and may not always be published in a way that contributes to impact factor.

    Interdisciplinary Research:

    • Complex Measurement: Interdisciplinary journals can have varied impact factors depending on the range of subjects they cover.
    • Citation Practices: Varying citation norms across disciplines can complicate the interpretation of impact factors for interdisciplinary journals.

    Understanding the discipline-specific nuances of impact factor can help researchers make more informed choices about where to publish and how to interpret impact factors in their field.

    10. Role of Impact Factor in Journal Selection

    Impact factor plays a significant role in how both authors and readers choose academic journals. Here are some key points to consider:

    For Authors:

    • Visibility: Publishing in a high-impact journal often leads to higher visibility and more citations, which can be beneficial for academic recognition.
    • Career Advancement: Many institutions consider the impact factor when assessing a researcher’s performance, making it an important criterion for career development.
    • Credibility: A high impact factor can lend an air of credibility to researchers, particularly those early in their careers.

    For Readers and Researchers:

    • Quality Indicator: Though it has its limitations, many readers view impact factor as a quick gauge for a journal’s quality or relevance in a field.
    • Citation Worthiness: Researchers may scan articles from high-impact journals when looking for reliable sources to cite.

    For Journal Editors and Publishers:

    • Attracting Submissions: A high impact factor is a selling point for journals to attract quality manuscripts.
    • Marketing: Journals often advertise their impact factors prominently as part of their marketing strategy.

    11. Tips for Improving Your Impact Factor

    Improving your impact factor as a researcher can be a multi-pronged approach:

    1. Target High-Impact Journals: Your work is more likely to be cited if it is published in a well-regarded journal.
    2. Quality Over Quantity: Focus on publishing fewer, but higher-quality, in-depth articles.
    3. Network: Collaborate with leading researchers in your field to increase the visibility of your work.

  • Levels or Categories of Scopus Journals: Q1 Q2 Q3 Q4 Journal Categories

    What are the distinctions between q1, q2, q3, and q4 categories or level of journal? View the following clarification

    Scopus

    Scopus Journal Categories

    Scopus is an international journal indexing service that offers journal evaluations. Scopus splits the quality of journals into different levels when evaluating them. The degree of quality of Scopus journals is also known as the quartile.

    In the evaluation of the quality of journals indexed in the Scopus database, quartile can be thought of as a grouping or clustering. There are four groups of journals, notably quartile 1 (Q1), quartile 2 (Q2), quartile 3 (Q3), and quartile 4 (Q4).

    Q1 Q2 Q3 Q4 Journal Differences

    As discussed previously, Scopus contains multiple categories of journals. Scopus journal levels are categorised into four quartiles: Q1, Q2, Q3, and Q4. Consequently, what is the distinction between Q1, Q2, Q3, and Q4 journals?

    The quality levels of Scopus journals are as follows, according to the book Research Funding Strategies in Universities to Improve Research Performance by Dr. Sri Suryaningsum, S.E., M. Si., Ak., C.A., et al (2020):

    • Quartile 1 (Q1) is the highest level, denoting the most influential Scopus-indexed journal.
    • After Quartile 1 (Q1), Quartile 2 (Q2) represents Scopus-indexed journals with high importance.
    • Quartile 3 (Q3) represents the proportion of Scopus-indexed journals of moderate influence.
    • Quartile 4 (Q4) represents the percentage of Scopus-indexed journals with the least impact.

    This quartile classification is based on the calculation of the number of cite scores from Scopus-indexed articles. The journal with the highest citation score will be included in the first quartile (Q1). Additionally, journals with the lowest citation score will be included in quartile 4 (Q4). Therefore, you may conclude that Q1 Journal is the most prestigious journal because it has the highest citation score. In contrast, Q4 journals are the lowest level of journals due to their low cite score.

    How to check the categories of journals in Scopus?

    On the Scimago Journal & Country Rank (SJR) website, we can really view the quartile for the Scopus journal. Most of the time, though, Scimago journal rankings are slow to update information about quartile Scopus journals. Due to the fact that Scimago Journal & Country Rank (SJR) does not retrieve data from Scopus in real time, Scimago data lags behind the most recent Scopus data.

    The good news is that, as of 2017, Scopus provides information about a journal’s quartile on its website. Therefore, we should directly use the official Scopus website at https://www.scopus.com/ to determine a journal’s quartile.

    We may determine the quartile of a journal based on the percentile value reported by Scopus for the journal. If the quartile splits the data distribution into four parts, the percentile divides the data into 100 parts, or between 0 and 99 percent. To determine the journal’s quartile based on percentile, the following categories can be used:

    • Quartile Journal 1 (Q1) is a journal that has a percentile of 75%-99%.
    • Quartile Journal 2 (Q2) is a journal that has a percentile of 50%-74%.
    • Quartile Journal 3 (Q3) is a journal that has a percentile of 25%-49%.
    • Quartile Journal 4 (Q4) is a journal that has a percentile of 0%-24%.

    If the journal we checked has a highest percentile of 75% or more, it is considered a Q1 journal. If the journal we checked has a higher percentile than 74%, however, it will be classified as a Q2 journal.

    Follow these steps to find the journal’s quartile on Scopus:

    Visit https://www.scopus.com/, Scopus’s main website.

    You will find the following screen. It may be little different due to update in design.

    Scopus Home Screen

    Click on the source as mentioned in the figure.

    Scopus search screen

    Select title or ISSN, etc. as per your choice.

    Scopus search screen

    Write the name or ISSN as per your choice to find the journal listed in the Scopus. It would be better to choose ISSN, because you will get confirm one result if the journal is listed in Scopus.

    Scopus search result

    In the search result you will find the percentile, here the percentile is 17% that means the journal belongs to the 4th quartile.

    At the time of search if you will select the subject and enter the keyword (like “management’, “Supply-chain”, “working capital” etc. to find the relevant journal, in this case you can select the quartile as well to get the journal of a particular categories. However it is very important to verify that the journal is still on the Scopus list.

    To verify whether the journal is still in the Scopus list or not click on the journal to the specific journal page. Check whether in the coverage years “present” word is there or not as per the picture given below.

    Scopus

    Good luck for your research and journal selection.

  • What is h index and i10 index?

    h index and i10 index

    What is the h index? Hirsch index, as suggested by J.E. Hirsch in 2005, is abbreviated as “H.” The h index is an author-level indicator that seeks to gauge a scientist’s or scholar’s productivity as well as the influence of their publications on other scientists and academics’ work.

    h index and i10 index
    h index and i10 index

    Individual scientists and scholars were the first to benefit from the h index, which gauges the productivity and citation effect of a researcher’s work. For example, the h index is linked to Nobel Prizes, research scholarships and high-ranking employment at leading institutions. The index is based on the scientist’s most cited works and the number of citations they have gotten from other publications. Scholarly journals and groups of scientists, such as departments, universities, or countries, have both been included in the index’s most recent applications.

    Definition

    h index is the largest number of h such that h publication has at least h citation (Google, 2022). The h-index is defined as the maximum value of h such that the given author/journal has published at least h papers that have each been cited at least h times. The index seeks to go beyond more basic metrics like the total number of citations or publications. For optimum results, the index should be used to compare researchers in the same academic discipline. (Wikipedia, 2022).

    Calculation

    It is very easy to calculate. nn  means n paper should be cited n times. 1 h index means your one paper is cited one time. If you have 9 paper and all are cited one time even, then your h index will be one. It is because for two h index at least 2 papers must be cited two-two times. In the same way 3 h-index means you have at least 3 paper and all are cited three-three times. So, getting higher h index is difficult. So, for 10 h index means out of your all paper (suppose you have fifty paper) at least ten papers must be cited ten-ten times.

    Example:

    Calculate the h index of the author from the following table.

    S. No.PaperCitationS. No.PaperCitation
    1Paper 11911Paper 116
    2Paper 21512Paper 125
    3Paper 31313Paper 133
    4Paper 41214Paper 141
    5Paper 51115Paper 150
    6Paper 61116Paper 160
    7Paper 71117Paper 170
    8Paper 81018Paper 180
    9Paper 91019Paper 190
    10Paper 101020Paper 200
    h index and i10 index
    1. What is the h index of the above author?
    2. How can he increase one index with minimum citation?

    Answer:

    1.  The author has 10 papers with 10 citation each. Therefore, his h index is 10.
    2. To increase one index his h index must be 11. That means he must have 11 papers with 11 citations each. From the above table it is clear that the author has 7 papers with 11 citations, in remaining 4 paper he needs 11 citations. His paper 8, 9 and 10 is having 10 citation each therefore he needs one-one citation in each paper. The eleventh paper is having only 6 citations therefore, 5 more citation is required to reach 11 citations. As a result, he requires total 8 citation to reach the 11 h-index. It is shown in the table as follows
    S. No.PaperCitationS. No.PaperCitation
    1Paper 11911Paper 116 + 5
    2Paper 21512Paper 125
    3Paper 31313Paper 133

    10Paper 1010 + 120Paper 200
    h index and i10 index

    i10 Index

    i10 Index is comparatively easy to understand.

    i10-Index = the number of publications with at least 10 citations. 

    This very simple measure is only used by Google Scholar, and is another way to help gauge the productivity of a scholar. 

    How to find h index?

    Use Google Scholar to get your h index and i10 index.

    1. If you have your google account, then go to this link https://scholar.google.com/ otherwise create your account first.
    2. Click on “My Library” and then click on “My Profile”.
    3. Click on the + sign as shown in the picture and add your research paper.
      1. If you will select the “Add Article” then Google will give you automatic suggestion to add the paper.
      1. The other way is to select the “Add article manually”.
    4. Add your article Google will create the h-index and i10 index automatically.

  • How to write unique article or plagiarism free article?

    In a discussion, Mr. Noah asked, “What is Plagiarism and how can I remove it? This question is infarct about “How to write unique article or plagiarism free article?”

    How to write unique article or plagiarism free article?

    Definition of Plagiarism

    In fact, in a simple word, plagiarism is the other author’s language and thought, that you use in your original work without permission or close imitation. It includes not only copying sentence or paragraph word by word from other work but also the close imitation of his passage. So changing the sentence using synonyms and other lexical choice is no excuse to justify plagiarism. 
    You must write a text strictly in your own word and then cite your source. You can understand it by the following example. 

    Original Source: 

    Consumer behavior is the study of consumers and the processes they used to choose, use (consume), and dispose of products and services, including consumers’ emotional, mental, and behavioral responses [1].

    An example of plagiarism: 

    Customer behavior is the research study of consumers and the procedures they used to select, utilize (take in), and get rid of services and products, consisting of customers’ emotional, psychological, and behavioral reactions.

    An example of without plagiarism:

    Study of consumer behavior includes consumers’ behavioral response that may be mental or emotional that direct the customer to choose a product to consume and its uses and ultimately how he/she deposes it off.

    However, the sentence highlighted in red will come under plagiarism, but it may cheat the plagiarism detection software. The above example is called spinning the article, and there are several free and paid free spinning article software is available. One of them is most advanced and use artificial intelligence is Spin Rewriter. 

    Plagiarism also include:

    • downloading an article from the internet 
    • hire someone to write something for you (If you are claiming it your own work, otherwise it is fine. You may hire people to write content for your website or blog.)
    • try to make other people’s ideas appear to be your own idea. 
    How to remove plagiarism from the article?

    Be familiar with the area before writing on it 

    One you will understand the topic well, you will be more comfortable to write the your thought in your own word rather than copying someone else content or rewriting it by rephrasing it. It can be on the internet or in books, although books are almost always more authoritative than content on the internet.

    Tip: The idea in this case is to go through different sources of information of your topic. If your will study only one source i.e. a book or one website page, then there is a high chance of inadvertently copying or plagiarizing your content, if you rely on three books, some websites, one or two documentary and one or two video lectures, the chances are much lower that you will inadvertently plagiarize your content.”

    If you will copy the content using over 10 sources and then paraphrase it using some spinning software like Spin Rewriter, Google or plagiarism checking software cannot detect the plagiarism. It is a good idea if your are running marketing complain or writing content of your website. 

    Reformulate the topic to yourself several times

    The key is to understand the content of the text and to be able to express its meaning in your own words. Reading an author’s text too often will make you more inclined to rephrase that author’s text because your idea is not yet become independent. Another example of rewrite the original content in your own word is blew

    • The original source  : “The slaves worked grueling 12-hour days from sunrise to sunset, surviving on just under 1,200 calories of starchy foods and their superhuman efforts. “
    • An example of rewriting  : “In the 19th century, slaves were forced to work whole day without adequate food, that was only half of he recommended food recommended by the nutrition, even though they ware working hard whole day” (Thomas Jefferson).
    • Another rewrite example  : “In the 19th century, slaves worked as long as it was daylight, receiving very little nutrition” (Thomas Jefferson).

    Include your quotes and sources 

    Cite the original source and should include a bibliography of the original source you are using in your content. If you are using a direct quote from another author’s work, then reproduce it and cite the reference correctly. MLA is developed by Modern Language Association and widely accepted in citation and referencing. You can use it for your work unless another standard is pacified, like APA style.  

    Tip: You can avoid plagiarism by adding quotes and citing sources immediately. If you don’t write down the sources immediately, you might forget to do so later.”

    Are you in doubt, how to cite your sources?

    There are a lot of ways to do this so as to avoid plagiarism. Here are a few.

    • Mention the source inside your paragraph: “According to Richard Feynman, quantum electrodynamics can be described using path integrals. “
    • Quote between single phrases that you think can be interpreted as being copied: “A ‘paradigm shift’ occurs when a scientific revolution forces the community to think about the world in a fundamentally different way. “

    You need to understand a few basics about copyright

    Plagiarism is not only bad academic practice but also it is a violation of the law if you infringe copyright. Here’s what you need to understand in order to stay legal.

    • As a rule, facts cannot be subject to copyright. You can write any fact in your text in your own word. This means you have the right to use whatever facts you find to support your writing.
    • Although facts are not subject to copyright, the words used to express them are, especially if the wording is original or unique (copyright covers original expressions). You are free to use information from other content in your articles, but you should use your own words to express them. To avoid plagiarism, you can take the existing facts and write them down in your own words. There is a certain grace in the way a sentence is rotated, it is not enough to add a comma. However, changing the grammar can be satisfactory.

    Understand what need not be cited 

    In academic research, it is unnecessary to name even the smallest thing, otherwise the research would be too painful for people to undertake. The following items need not be cited in your research and final versions of your articles.

    • Common sense sightings, folklore (folk tales), urban legends, and well-known historical events, such as the date of the attack on Pearl Harbor.
    • Your own experiences, ideas, creations, thoughts.
    • If you reuse information that you previously used to write a book or article, you will need to ask permission from the publisher to reuse it for new work or add it as quotes.
    • Your personal videos, presentations, music and other media created and generated by you.
    • If you are reusing musical passages that you previously used to write a book or article, you will need to ask the publisher’s permission to reuse them for a new work and you will have to mention their origins.
    • The scientific evidence that you have gathered after performing your own tests, surveys, etc.

    Working Suggestion

    Here is the best way to write an article in your own word in record time. 

    • Take an article from another language for example Hindi, or French and translate it using Google translate or Microsoft word (translation option is available in Office 365) in English then use Spin Rewriter to rewrite the content.  That’s it. For publishing the content in blog and for your website proper use of Spin Rewriter is enough to publish the content. If you are writing the content for your research paper, then involve one more step. Before translating directly in English, first translate in some other language and then translate in English. You will then arrive at extremely wobbly English, which will be barely understandable. Using the knowledge on the subject that you have accumulated from reading the articles and doing your research, you can now correct flawed English and rewrite using Spin Rewriter. Believe me, that is your own content with no plagiarism. However, using Spin Rewriter is a little tricky. Spend some time to learn the options to get maximum out of it. 
    • If you must copy, don’t copy entire pages or paragraphs! Instead, put the gist of the source text in your own words and quote the copied portion. Then cite your source using the appropriate bibliographic standard. You can take a different program or website service to cite the content correctly and generate the bibliography accurately.  I will recommend the Microsoft Word inbuilt function of citation if you are using Microsoft office to write your content. 
    • Even though you are writing honestly, you have still a chance to plagiarizing someone else’s text. Therefore, it is better to check the plagiarism before publishing it. 
    How to check plagiarism?

    Yes, excellent question. I will discuss next time
