Event-Driven Query Expansion [PDF]
Proceedings of the 14th ACM International Conference on Web Search and Data Mining, 2021 A significant number of event-related queries are issued in Web search. In this paper, we seek to improve retrieval performance by leveraging events and specifically target the classic task of query expansion. We propose a method to expand an event-related query by first detecting the events related to it.

A fuzzy ontology framework in information retrieval using semantic query expansion
International Journal of Information Management Data Insights, 2021 World Wide Web (WWW) constitutes fuzzy information and requires soft computing techniques to deal context of the query. It works on the principle of keyword matching yielding low precision and recall.

Query expansion using the clustering of pseudo relevant documents with query sensitive similarity [PDF]
مجله 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]
Data & 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]
Information 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
Journal 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 ...

A New Approach in Query Expansion Methods for Improving Information Retrieval
Jurnal 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 ...
