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 ...

Re-examining the potential effectiveness of interactive query expansion [PDF]

open access: green, 2003
Much attention has been paid to the relative effectiveness of interactive query expansion versus automatic query expansion. Although interactive query expansion has the potential to be an effective means of improving a search, in this paper we show that,

Toward personalized query expansion [PDF]

open access: greenProceedings 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 ...

A competitive environment for exploratory query expansion [PDF]

open access: green, 2008
Most information workers query digital libraries many times a day. Yet people have little opportunity to hone their skills in a controlled environment, or compare their performance with others in an objective way.

Translating queries into snippets for improved query expansion [PDF]

open access: bronzeProceedings 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]

open access: bronze, 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.

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 ...

A study on query expansion methods for patent retrieval [PDF]

open access: green, 2011
Patent retrieval is a recall-oriented search task where the objective is to find all possible relevant documents. Queries in patent retrieval are typically very long since they take the form of a patent claim or even a full patent application in the ...

Query recovery of short user queries [PDF]

open access: yesProceedings of the 33rd international ACM SIGIR conference on Research and development in information retrieval, 2010
User queries to search engines are observed to predominantly contain inflected content words but lack stopwords and capitalization. Thus, they often resemble natural language queries after case folding and stopword removal. Query recovery aims to generate a linguistically well-formed query from a given user query as input to provide natural language ...
