The input is not limited to a number of institutions. The output is written as a file "mtrx.net" in the Pajek format (edgelist). A further routine generates a second matrix "fmtrx.net" containing the same information as "mtrx.net", but fractionally counted. Fractional Counting of Authors and Addresses: Fraction.EXE <http://www.leydesdorff.net/software/fraction/fraction.exe> This website provides a routine to compute fractional values for the numbers of publications and citations in a set of papers downloaded from the Web-of-Science (v5). First, this set can be organized into a relational database using ISI.exe <http://www.leydesdorff.net/software/isi> . The resulting files can be used by fraction.exe as input. This program will add au2.dbf and cs2.dbf to the dbf-files generated by isi.exe with fractional counts of numbers of publications and citations. (See for integer counting instcoll.exe <http://www.leydesdorff.net/software/instcoll/instcoll.exe> .) ** apologies for cross-postings _____ Loet Leydesdorff Professor Emeritus, University of Amsterdam Amsterdam School of Communication Research (ASCoR) <mailto:[log in to unmask]> [log in to unmask] ; <http://www.leydesdorff.net/> http://www.leydesdorff.net/ Honorary Professor, <http://www.sussex.ac.uk/spru/> SPRU, University of Sussex; Guest Professor <http://www.zju.edu.cn/english/> Zhejiang Univ., Hangzhou; Visiting Professor, <http://www.istic.ac.cn/Eng/brief_en.html> ISTIC, Beijing; Visiting Professor, <http://www.bbk.ac.uk/> Birkbeck, University of London; <http://scholar.google.com/citations?user=ych9gNYAAAAJ&hl=en> http://scholar.google.com/citations?user=ych9gNYAAAAJ&hl=en _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
