It also seeks and deter methods and metrics for measurements. “By its very nature, it monitors and evaluates commu in science, because all measurements are derived from interactions between individual elem scientometry, citations form this basic interaction.” With the arrival of databases, new f bibliometric research such as citation mapping began to develop. Scientometry analyses scientific outputs based on scientific communication. Citation analy method. Citation analysis is a mathematical-statistical method, a basic research method in bibliom scientometry, which measures the relationships between authors, documents and scientific d basis of bibliographic citations and references. • It is an evaluation of the quality and relevance of scientific publications. • It examines information sources, the frequency of citations, which citations appear toge authors cite each other, or which sources are repeated in a given field. • It is a basic method of scientometry and bibliometry. • It uses data from citation index databases from the ISI Web of Science and the Scopus da • Citation analyses are used today mainly in the field of science evaluation. • The results of citation analyses are directly dependent on the source of the data, its e quality of the records and their metadata. • When interpreting the results of citation analyses, it is always necessary to take into possibilities and limits of the methods and sources used. ****************************************************************************************** * Citation and publication analysis ****************************************************************************************** Publication analysis is the basis of citation analysis. The two are inter-related. For a c idea of the state of science in a given area, the publication itself of articles, books, e analysed. From the results of the citation analysis it is possible to observe: the perform professional quality, influence and impact. The results depend on the data source, the exc extracts/footnotes), or the metadata. *========================================================================================= * Initial hypotheses of the citation analysis: *========================================================================================= • Source A, which cites source B, is semantically (regarding its meaning) related to this • According to the number of citations of the source, its significance can be assessed (th citations, the more significant the source) *========================================================================================= * Publication analysis: *========================================================================================= • Mathematical-statistical method dealing with the frequency of production of the publicat measurement. The following is the most frequently studied: geographical and scientific a period, type of scientific literature and others. *========================================================================================= * Citation index *========================================================================================= The citation index is a tool of citation analysis. It is about monitoring and recording th citations, according to other sources it can be any information source that uses a citatio to another document. The analysis of citation index can determine the future development o disciplines. *========================================================================================= * Web of Science *========================================================================================= • The Web of Science [ URL "https://ezdroje.cuni.cz/prehled/zdroj.php?lang=en&id=222"] dat easy-to-use tools for basic scientometric analyses • It is an online version of the well-known Science Citation Index databases. It includes monitoring of scientific articles and regularly updated bibliographic data (including ab articles from more than 8,000 leading worldwide scientific and professional journals fro science with more than 60 years of retrospection. • It contains Science Citation Index Expanded, Social Science Citation Index and Arts and Citation Index. • ISI indexes from each issue of the journal all its essential elements: own articles, boo databases, hardware, software, bibliographies, editorial materials, discussions, letters corrections, additions, chronologies and more. *========================================================================================= * Scopus *========================================================================================= • Scopus [ URL "https://ezdroje.cuni.cz/prehled/zdroj.php?lang=en&id=201"] is the largest abstract database of peer-reviewed literature: scientific journals, books, and anthologi a comprehensive overview of the results of world research in the field of science, techn social sciences and arts or humanities. • It is equipped with intelligent tools for monitoring, analysis and visualization of rese • It is updated daily, includes 55 million entries, 21,000 titles from more than 5,000 for *========================================================================================= * Basic concepts of citation analysis *========================================================================================= ------------------------------------------------------------------------------------------ Impact Factor: ------------------------------------------------------------------------------------------ Impact Factor (IF) is a measurement of the quality of scientific journals. It is defined a the number of citations that were recorded in the evaluated year for all the articles publ journal in the previous two years, to the total number of all these articles. ------------------------------------------------------------------------------------------ Calculation: ------------------------------------------------------------------------------------------ • Each year, the impact factor for the previous two years is assigned to the periodical. T impact factor for the year 2015 will use data from the years 2013 and 2014. The whole eq like this: • A / B = impact factor of a given journal in 2005 • A = how many times articles from a given journal published in 2003-04 were cited by othe 2005 • B = how many articles in total were published in it in the period 2003-2004 (correction comments, etc. are not counted) ------------------------------------------------------------------------------------------ Article Influence Score (AIS): ------------------------------------------------------------------------------------------ • Indicator of a journal rating in JCR • Used in governmental evaluations of science since 2017 ------------------------------------------------------------------------------------------ SJR - SCImago Journal Rank: ------------------------------------------------------------------------------------------ • Indicator of a journal rating in Scopus • Also used in governmental evaluations since 2017. ------------------------------------------------------------------------------------------ Journal ranking: ------------------------------------------------------------------------------------------ • Quartiles and deciles of the journal according to IF, AIS and SJR, i.e. the order of the given field according to an indicator. *========================================================================================= * Other methods of citation measurement: *========================================================================================= The impact factor alone is not the only way to measure the value of an article or journal. PageRank, Immediacy Index or Cited Half-life are also used. *========================================================================================= * H-index: *========================================================================================= The H-index is a tool of scientometry. It is numerical data indicating the impact of a sci his/her field of activity. The number h is the number of works of a scientist with the num greater than or equal to h. The total time of scientific activity is evaluated. The H-index is given by the number h, which is the number of works that have been cited at The total number of works is N. Therefore (N - h) works have less than h citations. The sc index of 50 published 50 works, each of which was cited at least 50 times (There will, the least 502 = 2500 citations). The H-index assumes that a good scientist publishes sufficiently and is sufficiently cited that the work, which is cited many times, is of good quality – in this regard Hirsch is cr impact factor (it tells how many times the articles were cited - mostly during the year), take into account the quality of each article separately and, therefore, the qualities of
