Abstract: Highlights•We propose a probabilistic framework integrating sentence-level semantic into PRF for expanding terms which are more semantically consistent with the query.•Three enhanced models are generated by applying the probability framework to Rocchio-based PRF models.•Experimental results highlight the proposed framework is robust and effective.
