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 ââ'¬" Wikipedia ââ'¬" 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 ââ'¬" corpus harvesting and paraphrasing ââ'¬" and present a preliminary empirical study that demonstrates the viability of our method.
