Abstract
As semantic markup becomes ubiquitous, it will become important to be able to ask queries and obtain answers, using natural language (NL) expressions, rather than the keyword-based retrieval mechanisms used by the current search engines. The Semantic Web (SW) opens the way to novel question answering (QA) systems, which can exploit the availability of distrib-uted semantic markup to provide precise, formally derive answers to questions. On the other hand, the distributed, heterogeneous, large-scale nature of the availability of semantic information raises many difficult challenges. Here, we describe the design of a QA system, PowerAqua, de-signed to exploit semantic mark-up on the web to provide answers to questions posed in NL. PowerAqua does not assume that the user has any prior information about semantic resources. The system takes an input a NL query, translates it into a set of logical queries, which are then answered by consulting and aggregating information derived from multiple heterogeneous seman-tic sources..
