WebTLab: A cooccurrence-based approach to KBP 2010 Entity-Linking task.
Norberto Fernández, Jesús Arias Fisteus, Luis Sánchez Fernández, Eduardo Martín Cabrera · 2010
In this paper we describe the approach followed and results obtained in the KBP-Entity Linking task of TAC 2010 by the Web Technologies Laboratory (WebTLab). The system implemented for the task is based on the intuition that instances in a knowledge base typically cooccur in documents with other related instances (for example, Obama and USA). Based on that intuition, the proposed system takes advantage of the information provided by the Wikipedia link structure to compute instance cooccurrence estimates, and uses them for disambiguation purposes, combinined with more classical techniques from the information retrieval community. 1
