Effects and their influence on citations
An effect as it relates to citationanalysis is any influencing factor that may change the number of citations an entity such as an author, workgroup, institution, or publication receives. The most well
The foundation of the IS constructing method is the citation and co-citationanalysis. The citationanalysis method was pioneered by Garfield et al. (Garfield et al. 1964 ). It is one of the informatics methods developed to analyze the documents
In this study an attempt is made to establish new bibliometric indicators for the assessment of research in the Humanities.
Data from a Dutch Faculty of Humanities was used to provide the investigation a sound empirical basis. For several reasons
(particularly related to coverage) the standard citation indicators, developed for the sciences, are unsatisfactory. Target
expanded citation analysis and the use of oeuvre (lifetime) citation data, as well as the addition of library holdings and
productivity indicators enable a more representative and fair assessment. Given the skew distribution of population data,
individual rankings can best be determined based on log transformed data. For group rankings this is less urgent because of
the central limit theorem. Lifetime citation data is corrected for professional age by means of exponential regression.

) and Glänzel ( 2007b , 2008 ) deduce the scaling parameter from an equation relating the h -index and the parameters of the assumed power law.
The vast majority of articles written in citationanalysis deal
In this study, half-life, citation degree, form dispersion and title dispersion of physic journals were investigated, and they were compaired in each subfield with those in other subfields.The results from this study were that, on the whole, in physics the most preferred medium for physicists is the journal; however, in the subfields in which large experimental or observational devices are used, the use of reports and letter journals is going to increase.
A new paradigm for comparing quality of published papers across different disciplines has been proposed. This method uses
a figure of merit of the ratio of actual citations received to the potential maximum number of citations that could have been
received. It is analogous to approaches used to compare performance in physical systems, and appears intrinsically more useful
than present approaches.
A comparison of sources cited in the Japanese language Geographical Review of Japan and six western language, Japanese geographical serials reveals that while both cite the same proportion of foreign sources (a third), authors tend to select Japanese sources which are written in the language of the host publication. Foreign sources in the Japanese literature are overwhelmingly from the English language world, especially the United States, with a small admixture in German, from the F.R. Germany. The proportion of foreign sources in the Japanese literature appears to be in decline.

A sample of 80 Hungarian scientists, authors or co-authors of a total number of 6273 papers—published between 1930–1976—has been analysed. Citation data to eachpaper were collected form the 1964–76 SCI's by manual search. Citation counts were distinguished with respect to the following categories: (I) the set of cited authors has element(s) common with the set of citing authors (self citation), (II) condition I is not satisfied, but the cited author under study and at least one of the citing authors were co-authors prior to the publication of the cited paper, (III) none of the former criteria is satisfied. The yearly average citation frequency of a paper was not corrected for obsolescence, since there is no evidence that the decay of citation frequency with time is independent of the absolute citedness of the paper. Individual performance has been measured (a) by the sum of the vearly average typeIII fractional citation frequencies over all of the author's papers, (b) by the sum of the yearly average citation frequency normalized to one single-authored paper per year over the period of the author's activity, (c) by the same as ina, but summed up only over the most highly cited papers scattering upwards from the individual's own average, (d) by the fractional authorship, and (e) by the number of items in the author's publication list. The first three parameters seem to be applicable in measuring the utility of the individual's scientific contribution with slightly different emphasis on different aspects. These parameters are uncorrelated with those measuring the output of individuals.
