"More like these": growing entity classes from seeds

Luís Sarmento, Valentin Jijkoun, Maarten de Rijke, Eugénio C. Oliveira

Abstract: We present a corpus-based approach to the class expansion task. For a given set of seed entities we use co-occurrence statistics taken from a text collection to define a membership function that is used to rank candidate entities for inclusion in the set. We describe an evaluation framework that uses data from Wikipedia. The performance of our class extension method improves as the size of the text collection increases.
