Abstract

In this paper we describe our participation in the INEX Entity Ranking track. We explored the relations between Wikipedia pages, categories and links. Our approach is to exploit both category and link information. Category information is used by calculating distances between document categories and target categories. Link information is used for relevance propagation and in the form of a document link prior. Both sources of information have value, but using category information leads to the biggest improvements.
