Abstract

This paper presents ListWebQA, a question answering system aimed specifically at discovering answers to list questions in web snippets. ListWebQA retrieves snippets likely to contain answers by means of a query rewriting strategy, and extracts answers according to their syntactic and semantic similarities afterwards. These similarities are determined by means of a set of surface syntactic patterns and a Latent Semantic Kernel. Results show that our strategy is effective in strengthening current web question answering techniques.
