  title={Experiment on Pseudo Relevance Feedback Method Using Taylor Formula at NTCIR-3 Patent Retrieval Task},
  author={Kazuaki Kishida},
Pseudo relevance feedback is empirically known as a useful method for enhancing retrieval performance. For example, we can apply the Rocchio method, which is well-known relevance feedback method, to the results of an initial search by assuming that the top-ranked documents are relevant a priori. In this paper, for searching NTCIR-3 patent test collection through pseudo feedback, we try to employ two relevance feedback mechanism; (1) the Rocchio method, and (2) a new method that is based on… CONTINUE READING
