Can Query Expansion Improve Generalization of Strong Cross-Encoder Rankers? [PDF]

open access: yesAnnual International ACM SIGIR Conference on Research and Development in Information Retrieval, 2023
Query expansion has been widely used to improve the search results of first-stage retrievers, yet its influence on second-stage, cross-encoder rankers remains under-explored.

Simple and Effective Knowledge-Driven Query Expansion for QA-Based Product Attribute Extraction [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2022
A key challenge in attribute value extraction (AVE) from e-commerce sites is how to handle a large number of attributes for diverse products. Although this challenge is partially addressed by a question answering (QA) approach which finds a value in ...

BERT-QE: Contextualized Query Expansion for Document Re-ranking [PDF]

open access: yesFindings, 2020
Query expansion aims to mitigate the mismatch between the language used in a query and in a document. However, query expansion methods can suffer from introducing non-relevant information when expanding the query.

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 ...

Conceptual query expansion [PDF]

open access: yesData & Knowledge Engineering, 2006
This article presents a new, hybrid approach that projects an initial query result onto global information, yielding a local conceptual overview. Concepts found this way are candidates for query refinement. We show that the resulting conceptual structure after a typical short query of 2 terms, contains refinements that perform just as well as a most ...

Combining fields for query expansion and adaptive query expansion [PDF]

open access: yesInformation Processing & Management, 2007
In this paper, we aim to improve query expansion for ad-hoc retrieval, by proposing a more fine-grained term reweighting process. This fine-grained process uses statistics from the representation of documents in various fields, such as their titles, the anchor text of their incoming links, and their body content.

Query Refinement into Information Retrieval Systems: An Overview

open access: yesJournal of Information and Organizational Sciences, 2023
Query, expressing the user need and requirement, has an important role, in an information retrieval system, for reaching a high accuracy search. In this paper, we present an overview of the different refinement operations that the query may undergo, in ...

Neural text generation for query expansion in information retrieval

open access: yesWI/IAT, 2021
Expanding users’ query is a well-known way to improve the performance of document retrieval systems. Several approaches have been proposed in the literature, and some of them are considered as yielding state-of-the-art results in Information Retrieval ...

A New Approach in Query Expansion Methods for Improving Information Retrieval

open access: yesJurnal Informatika, 2021
This research develops a new approach to query expansion by integrating Association Rules (AR) and Ontology. In the proposed approach, there are several steps to expand the query, namely (1) the document retrieval step; (2) the step of query expansion ...
