The MSR Systems for Entity Linking and Temporal Slot Filling at TAC 2013.

The paper describes the two systems from MSR that participated in the English Entity Linking and Temporal Slot Filling (TSF) tasks at TAC 2013. The entity linking system is built by using the same framework and architecture as the previous iterations that participated in the TAC 2011 and 2012 evaluations; therefore, its description focuses on the components that are novel with reference to those systems. The MSR system that addresses the newly introduced TSF task, employs a distant-supervision framework, in which language models for each targeted type of relation are built based on a corpus of sentences automatically extracted from Wikipedia text as guided by Wikipedia infobox data. For each of the TAC tracks addressed, we submitted two runs, which obtained the highest scores in their corresponding evaluations.
