Clustering of scientific citations in Wikipedia (slides) |
| | Abstract | The 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. | | Keywords | Wikipedia, non-negative matrix factorization, clustering, scientometrics, Wikimania, citation | | Type | Misc [Presentation] | | Journal/Book/Conference | Wikimania 2008 | | Year | 2008 Month July | | Publisher | Informatics and Mathematical Modelling, Technical University of Denmark | | Address | Richard Petersens Plads, Building 321, DK-2800 Kgs.
