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.

Toward personalized query expansion [PDF]
Proceedings 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 ...

Translating queries into snippets for improved query expansion [PDF]
Proceedings of the 22nd International Conference on Computational Linguistics - COLING '08, 2008 User logs of search engines have recently been applied successfully to improve various aspects of web search quality. In this paper, we will apply pairs of user queries and snippets of clicked results to train a machine translation model to bridge the "lexical gap" between query and document space.

Conqueries: An Agent That Supports Query Expansion [PDF]
, 2005 This article presents Conqueries, an agent that assists users during their searches on search engines. The system recommends terms and modifiers to users so that they can reformulate their queries. The system unobtrusively learns the user's current needs in order to propose personalized lists of keywords.
