Concept Based Pseudo Relevance Feedback in Biomedical Field

2009
Semantic information retrieval is based on calculating similarity between concepts in a query and documents of a corpus. In this regard, similarity between concept pairs is determined by using an ontology or a meta-thesaurus. Although semantic similarities often convey reasonable meaning, there are cases where calculated semantic similarity fails to ...

Utilizing Pseudo-Relevance Feedback in Fusion-based Retrieval

Proceedings of the 2018 ACM SIGIR International Conference on Theory of Information Retrieval, 2018
The usage of positive relevance feedback in fusion-based retrieval was previously shown to be very useful. Yet, in many retrieval use-cases, no actual relevance feedback may be available. With the absence of relevance data, pseudo-relevance feedback models have been suggested as an alternative.

Pseudo Topic Analysis for Boosting Pseudo Relevance Feedback

2019
Traditional Pseudo Relevance Feedback (PRF) approaches fail to mode real-world intricate user activities. They naively assume that the first-pass top-ranked search results, i.e. the pseudo relevant set, have potentially relevant aspects for the user query.
