Finding Domain Terms using Wikipedia

In this paper we present a new approach for obtaining the terminology of a given domain using the category and page structures of the Wikipedia in a language independent way. The idea is to take profit of category graph of Wikipedia starting with a top category that we identify with the name of the domain. After obtaining the full set of categories belonging to the selected domain, the collection of corresponding pages is extracted, using some constraints. For reducing noise a bootstrapping approach implying several iterations is used. At each iteration less reliable pages, according to the balance between on-domain and off-domain categories of the page, are removed as well as less reliable categories. The set of recovered pages and categories is selected as initial domain term vocabulary. This approach has been applied to three broad coverage domains: astronomy, chemistry and medicine, and two languages: English and Spanish, showing a promising performance. The resulting set of terms...
