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 ...

Toward personalized query expansion [PDF]

open access: yesProceedings of the Second ACM EuroSys Workshop on Social Network Systems, 2009
Social networking and tagging have taken off at an unexpected scale and speed, opening huge opportunities to enhance the user search experience. We present Gossple, a new, user-centric, approach to improve the exploration of the Internet. Underlying \textsc{Gossple} lies the intuition that while social networks provides news from your old buddies, you ...

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.

A Semantic Query Expansion Method for Question Answering Based on Knowledge Graph [PDF]

open access: yesJisuanji gongcheng, 2019
In Question Answering(QA) system,the query intent that is expressed only by the words in the question may not be able to get the ideal answer from the data source.To this end,a semantic query expansion method is proposed for QA system based on knowledge ...

A query expansion method based on topic modeling and DBpedia features

open access: yesInternational Journal of Information Management Data Insights, 2021
Query Expansion (QE) is a method used for improving Information Retrieval (IR) by adding the terms that are almost selected from feedback documents, and similar to the user query terms.

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 ...
