Table 5 illustrates the main distribution of document types in both groups (all and highly cited papers).
Articles referring to acupuncture were assessed by distribution of document types, languages, journals, subject categories, source countries, and source institutes.
In this paper, the distribution of document types, language, year of publication, subjects, journals, countries, institutions, authors, highly multiple cited papers, high frequency keywords, and cluster analysis, as well as collaboration of the subjects, countries, institutions, and authors were thoroughly examined.
There are several visualization tools based on this idea, which show the geographical distribution of documents, allowing users to answer specific questions.
It was published in Geophysics journal in 1957, and one of the co-authors (Kintzinger, P. R). was from The Desert Institute; Mataria; Egypt. Figure 1 shows the distribution of documents published per year from Arab world with comparison to evolution of annual publications at global level.
The distribution of documents was relatively even: acts and amendments, 30%; policy and developing legislation, 19%; internal documents, 26%; and legislative instruments, 25%.
Although there are no previous examples of unsupervised feature selection for metagenomics, it is a common practice in information retrieval with text documents (Yang and Pedersen, 1997); a particularly relevant method assesses the entropy of the distribution of documents in which a specific term occurs (Largeron et al., 2011).
We present a solution for the identification of PPIs from the scientific literature, which is unique in the sense that it combines IR and IE for PPIs and delivers high recall versus high precision results from the same distribution of documents.
The distributions of document length for all three collections can be approximated by lognormals shown in Fig. 4, with different first and second moment parameters.
The review then focusses on Africa as a case study, comparing research efforts in domesticated animals and bats with the distributions of documented human cases.
While this is sufficient for comparing the shape of the probability distributions of documents, we also color the strips with a distinct color representing the topic, as shown in Figure 2B in the bottom row.
