Abstract
This paper proposes a query expansion method for cooking question answering system based on pragmatic analysis. In our approach, the results of question analysis is used. The original queries are generated by means of the question subject, then the query terms are expanded based on pragmatic function. When submitting the expended queries to Google search engine to retrieve related passages, we get an overall improvement of 36.2% on the mean average precision.
