TL;DR

The HLTCOE participated in the entity linking and slot filling tasks at TAC 2009 and found that slot-filling based on sentence selection, application of weak patterns and exploitation of redundancy was ineffective in the slot filling task.

Abstract

The HLTCOE participated in the entity linking and slot filling tasks at TAC 2009. A machine learning-based approach to entity linking, operating over a wide range of feature types, yielded good performance on the entity linking task. Slot-filling based on sentence selection, application of weak patterns and exploitation of redundancy was ineffective in the slot filling task.
