A Semantic Approach to Question Answering Systems

This paper describes the architecture, operation and results obtained with the Question Answering prototype developed in the Department of Language Processing and Information Systems at the University of Alicante. Our approach accomplishes question representation by combining keywords with a semantic representation of expected answer characteristics. Answer string ranking is performed by computing similarity between this representation and document sentences.
