Clustering of scientific citations in Wikipedia (slides)

Finn Årup Nielsen

AbstractThe instances of templates in Wikipedia form an interesting data set of structured information. Here I focus on the cite journal template that is primarily used for citation to articles in scientific journals. These citations can be extracted and analyzed: Non-negative matrix factorization is performed on a (article x journal) matrix resulting in a soft clustering of Wikipedia articles and scientific journals, each cluster more or less representing a scientific topic.
KeywordsWikipedia, non-negative matrix factorization, clustering, scientometrics, Wikimania, citation
