'''Identifying Document Topics Using the Wikipedia Category Network''' - scientific work related to [[Wikipedia quality]] published in 2006, written by [[Peter Sch]].

== Overview ==
In the last few years the size and coverage of [[Wikipedia]], a freely available on-line encyclopedia has reached the point where it can be utilized similar to an [[ontology]] or taxonomy to identify the topics discussed in a document. In this paper authors will show that even a simple algorithm that exploits only the titles and [[categories]] of Wikipedia articles can characterize documents by [[Wikipedia categories]] surprisingly well. Authors test the [[reliability]] of method by predicting categories of Wikipedia articles themselves based on their bodies, and by performing classification and clustering on 20 Newsgroups and RCV1, representing documents by their Wikipedia categories instead of their texts.
