About Term Ranking Methods in Relevance Feedback
|
Abstract:
One common method for query expansion is relevance feedback, and much research work has been done to it. Relevance feedback focuses two aspects: term reweighting and term selection. In this paper, the authors elaborate a few classical term ranking methods, and compare them in retrieval performance. At last, they discuss the problems in implementing relevance feedback.
