SURFACE LANGUAGE MODELS FOR DISCOVERING TEMPORALLY ANCHORED DEFINITIONS ON THE WEB - Producing Chronologies as Answers to Definition Questions

Alejandro Figueroa

2010

Abstract

This work presents a data-driven definition question answering (QA) system that outputs a set of temporally anchored definitions as answers. This system builds surface language models on top of a corpus automatically acquired from Wikipedia abstracts, and ranks answer candidates in agreement with these models afterwards. Additionally, this study deals at greater length with the impact of several surface features in the ranking of temporally anchored answers.
