چکیده

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.

HLTCOE Efforts in Entity Linking at TAC KBP 2010

This report documents the HLTCOE submission to the 2010 Text Analysis Conference Knowledge Base Population Track Entity Linking task. This year we incorporated a number of engineering changes to simplify our 2009 system, and as a results the new software runs approximately 20 times faster than the previous version. We also eschewed use of the Internet entirely. Details of the HLTCOE prototype s...
