Evaluation of a Query-biased Document Summarisation Approach for the Question Ansnwering Task

This paper presents an approach on a querybiased document summarisation and an evaluation of the use of such an approach for question answering tasks. We observed a significant difference in the user’s performance by presenting a list of documents customized to the task type, compared with a generic document summarization approach. This indicates that paying attention to the task and the searcher interaction may provide substantial improvement in task performance.
