Study of Query Expansion Techniques and Their Application in the Biomedical Information Retrieval [PDF]

open access: goldThe Scientific World Journal, 2014
Information Retrieval focuses on finding documents whose content matches with a user query from a large document collection. As formulating well-designed queries is difficult for most users, it is necessary to use query expansion to retrieve relevant ...

Coupled intrinsic and extrinsic human language resource-based query expansion [PDF]

open access: greenKnowledge & Information Systems 2018, 2020
Poor information retrieval performance has often been attributed to the query-document vocabulary mismatch problem which is defined as the difficulty for human users to formulate precise natural language queries that are in line with the vocabulary of the documents deemed relevant to a specific search goal.

A multi-dimensional semantic pseudo-relevance feedback framework for information retrieval [PDF]

open access: yesScientific Reports
Pre-trained models have garnered significant attention in the field of information retrieval, particularly for improving document ranking. Typically, an initial retrieval step using sparse methods such as BM25 is employed to obtain a set of pseudo ...

Query expansion using the clustering of pseudo relevant documents with query sensitive similarity [PDF]

open access: yesمجله مدل سازی در مهندسی, 2017
Query expansion as one of query adaptation approaches, improves retrieval effectiveness of information retrieval. Pseudo-relevance feedback (PRF) is a query expansion approach that supposes top-ranked documents are relevant to the query concept, and ...

Using Query Expansion in Manifold Ranking for Query-Oriented Multi-Document Summarization [PDF]

open access: yesCCL2021, 2021
Manifold ranking has been successfully applied in query-oriented multi-document summarization. It not only makes use of the relationships among the sentences, but also the relationships between the given query and the sentences. However, the information of original query is often insufficient.
