YAGO-QA: Answering Questions by Structured Knowledge Queries
3 Proceedings of the Fifth IEEE International Conference on Semantic Computing (IEEE-ICSC 2011), Pages 158-161, Palo Alto, California, USA, IEEE, IEEE, 9/2011
 
We present a natural-language question-answering system that gives access to the accumulated knowledge of one of the largest community projects on the Web -- Wikipedia -- via an automatically acquired structured knowledge base. Key to building such a system is to establish mappings from natural language expressions to semantic representations. We propose to acquire these mappings by data-driven methods -- corpus harvesting and paraphrasing -- and present a preliminary empirical study that demonstrates the viability of our method.
