A Simple Distant Supervision Approach for the TAC-KBP Slot Filling Task

This paper describes the design and implementation of the slot filling system prepared by Stanford’s natural language processing group for the 2010 Knowledge Base Population (KBP) track at the Text Analysis Conference (TAC). Our system relies on a simple distant supervision approach using mainly resources furnished by the track organizers: we used slot examples from the provided knowledge base, which we mapped to documents from several corpora, i.e., those distributed by the organizers, Wikipedia, and web snippets. Our implementation attained the median rank among all participating systems.
