The paper is based on simulating many user scenarios regarding the amount and quality of RFB. In addition, we experiment with query-biased sentence extraction for query reformulation. The baselines are initial nofeedback queries and queries based on pseudo-relevance feedback. The core question is: under which conditions would RFB based on sentence extraction be successful? The answer depends on user's behavior, implementation of feedback query formulation, and the evaluation methods. A small amount of feedback from a short browsing window seems to improve the final ranking the most. Longer browsing allows more feedback and better queries but also consumes the available relevant documents. Categories and Subject Descriptors H.3.1 [Content analysis a...
