I10-index
Author-level metrics are citation metrics that measure the bibliometrics, bibliometric impact of individual authors, researchers, academics, and scholars. Many metrics have been developed that take into account varying numbers of factors (from only considering the total number of citations, to looking at their distribution across papers or Academic journal, journals using statistical or Graph theory, graph-theoretic principles). The main motivation for these quantitative comparisons between researchers is to allocate resources (e.g. funding, academic appointments). However, there remains controversy in the academic community as to how well author-level metrics achieve this goal. Author-level metrics differ from journal-level metrics which attempt to measure the bibliometric impact of academic journals rather than individuals. However, metrics originally developed for academic journals can be reported at researcher level, such as the author-level eigenfactor and the author impact f ...

Google Scholar
Google Scholar is a freely accessible web search engine that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other scholarly literature, including court opinions and patents. Google Scholar uses a web crawler, or web robot, to identify files for inclusion in the search results. For content to be indexed in Google Scholar, it must meet certain specified criteria. An earlier statistical estimate published in PLOS One using a mark and recapture method estimated approximately 80–90% coverage of all articles published in English with an estimate of 100 million.''Trend Watch'' (2014) Nature 509(7501), 405 – discussing Madian Khabsa and C Lee Giles (2014''The Number of Scholarly Documents on the Public Web'' ...

Citation Metrics
Citation impact is a measure of how many times an academic journal article or book or author is cited by other articles, books or authors. Citation counts are interpreted as measures of the impact or influence of academic work and have given rise to the field of bibliometrics or scientometrics, specializing in the study of patterns of academic impact through citation analysis. The journal impact factor, the two-year average ratio of citations to articles published, is a measure of the importance of journals. It is used by academic institutions in decisions about academic tenure, promotion and hiring, and hence also used by authors in deciding which journal to publish in. Citation-like measures are also used in other fields that do ranking, such as Google's PageRank algorithm, software metrics, college and university rankings, and business performance indicators. Article-level One of the most basic citation metrics is how often an article was cited in other articles, books, or ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coercive Citation
Coercive citation is an academic publishing practice in which an editor of a scientific or academic journal forces an author to add spurious citations to an article before the journal will agree to publish it. This is done to inflate the journal's impact factor, thus artificially boosting the journal's scientific reputation. Manipulation of impact factors and self-citation has long been frowned upon in academic circles; however, the results of a 2012 survey indicate that about 20% of academics working in economics, sociology, psychology, and multiple business disciplines have experienced coercive citation. Individual cases have also been reported in other disciplines. Background The impact factor (IF) of a journal is a measure of how often, on average, papers published in the journal are cited in other academic publications. The IF was devised in the 1950s as a simple way to rank scientific journals. Today, in some disciplines, the prestige of a publication is determined largely ...

SCIgen
SCIgen is a paper generator that uses context-free grammar to randomly generate nonsense in the form of computer science research papers. Its original data source was a collection of computer science papers downloaded from CiteSeer. All elements of the papers are formed, including graphs, diagrams, and citations. Created by scientists at the Massachusetts Institute of Technology, its stated aim is "to maximize amusement, rather than coherence." Originally created in 2005 to expose the lack of scrutiny of submissions to conferences, the generator subsequently became used, primarily by Chinese academics, to create large numbers of fraudulent conference submissions, leading to the retraction of 122 SCIgen generated papers and the creation of detection software to combat its use.

Gaming The System
Gaming the system (also rigging, abusing, cheating, milking, playing, working, or breaking the system, or gaming or bending the rules) can be defined as using the rules and procedures meant to protect a system to, instead, Psychological manipulation, manipulate the system for a desired outcome. According to James Rieley, a British advisor to CEOs and an author, structures in companies and organizations (both explicit and implicit policies and procedures, stated goals, and mental models) drive behaviors that are detrimental to long-term organizational success and stifle competition. For some, error is the essence of gaming the system, in which a gap in protocol allows for errant practices that lead to unintended results. Although the term generally carries negative connotations, gaming the system can be used for benign purposes in the undermining and dismantling of corrupt or oppressive organisations. History The first known documented use of the term "gaming the system" is in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jorge E
Jorge is a Spanish and Portuguese given name. It is derived from the Greek name Γεώργιος (''Georgios'') via Latin ''Georgius''; the former is derived from (''georgos''), meaning "farmer" or "earth-worker". The Latin form ''Georgius'' had been rarely given in Western Christendom since at least the 6th century. The popularity of the name however develops from around the 12th century, in Occitan in the form ''Jordi'', and it becomes popular at European courts after the publication of the ''Golden Legend'' in the 1260s. The West Iberian form ''Jorge'' is on record as the name of Jorge de Lencastre, Duke of Coimbra (1481–1550).

Impact Factor
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science. As a journal-level metric, it is frequently used as a proxy for the relative importance of a journal within its field; journals with higher impact factor values are given the status of being more important, or carry more prestige in their respective fields, than those with lower values. While frequently used by universities and funding bodies to decide on promotion and research proposals, it has come under attack for distorting good scientific practices. History The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information (ISI) in Philadelphia. Impact factors began to be calculated yearly starting from 1975 for journals listed in the ''Journal Citation Rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geometric Mean
In mathematics, the geometric mean is a mean or average which indicates a central tendency of a set of numbers by using the product of their values (as opposed to the arithmetic mean which uses their sum). The geometric mean is defined as the th root of the product of numbers, i.e., for a set of numbers , the geometric mean is defined as :\left(\prod_^n a_i\right)^\frac = \sqrt /math> or, equivalently, as the arithmetic mean in logscale: :\exp For instance, the geometric mean of two numbers, say 2 and 8, is just the square root of their product, that is, \sqrt = 4. As another example, the geometric mean of the three numbers 4, 1, and 1/32 is the cube root of their product (1/8), which is 1/2, that is, \sqrt = 1/2. The geometric mean applies only to positive numbers. The geometric mean is often used for a set of numbers whose values are meant to be multiplied together or are exponential in nature, such as a set of growth figures: values of the human population or inter ...

G-index
The ''g''-index is an author-level metric suggested in 2006 by Leo Egghe. The index is calculated based on the distribution of citations received by a given researcher's publications, such that given a set of articles ranked in decreasing order of the number of citations that they received, the ''g''-index is the unique largest number such that the top ''g'' articles received together at least ''g''2 citations. Hence, a ''g''-index of 10 indicates that the top 10 publications of an author have been cited at least 100 times (102), a ''g''-index of 20 indicates that the top 20 publications of an author have been cited 400 times (202). It can be equivalently defined as the largest number ''n'' of highly cited articles for which the average number of citations is at least ''n''. This is in fact a rewriting of the definition :g^2 \le \sum_c_ as :g \le \frac1g \sum_c_ The ''g''-index is an alternative for the older ''h''-index. The ''h''-index does not average the number of citat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
