Two birds with one stone: Learning semantic models for text categorization and word sense disambiguation is a 2011 conference paper written in English by Navigli R., Faralli S., Soroa A., De Lacalle O., Agirre E. and published in International Conference on Information and Knowledge Management, Proceedings.

[edit] Abstract

In this paper we present a novel approach to learning semantic models for multiple domains, which we use to categorize Wikipedia pages and to perform domain Word Sense Disambiguation (WSD). In order to learn a semantic model for each domain we first extract relevant terms from the texts in the domain and then use these terms to initialize a random walk over the WordNet graph. Given an input text, we check the semantic models, choose the appropriate domain for that text and use the best-matching model to perform WSD. Our results show considerable improvements on text categorization and domain WSD tasks.
