Abstract

This paper introduces category and link expansion strategies for the XML Entity Ranking track at INEX 2007. Category expansion is a coefficient propagation method for the Wikipedia category hierarchy based on given categories or categories derived from sample entities. Link expansion utilizes links between Wikipedia articles. The strategies are evaluated within the entity ranking and list completion tasks.

Keywords
