Using query contexts in information retrieval

Jing Bai, Jian-Yun Nie, Guihong Cao, Hugues Bouchard
2007 Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '07  
In this study, we propose to use query-specific contexts instead of user-centric ones, including context around query and context within query.  ...  Our experiments on several TREC collections show that each of the context factors brings significant improvements in retrieval effectiveness.  ...  However, little information is available in the relation to help us determine if an application context is appropriate.  ...

Exploration of query context for information retrieval

Keke Cai, Chun Chen, Jiajun Bu, Peng Huang, Zhiming Kang
2007 Proceedings of the 16th international conference on World Wide Web - WWW '07  
A number of existing information retrieval systems propose the notion of query context to combine the knowledge of query and user into retrieval to reveal the most exact description of user's information  ...  In this paper we interpret query context as a document consisting of sentences related to the current query.  ...  Different notions of query context have been used in many retrieval systems. In this paper, we interpret query context from a different perspective.  ...

A New Approach for Context Based Indexing in IR System Using BST

Pooja Bhardwaj, Rajbala Tanwar, Renu Singla
2014 International Journal of Engineering Trends and Technoloy  
In this paper we introduce a context-based retrieval model which uses binary Search Tree BST for creating context based index.  ...  However, keyword-based searching does not always result to the retrieval of qualitative data, basically due to the variety in the vocabulary used to convey alike information.  ...  First of all a sample corpus of 11 documents in 4 contexts has been taken. Figure-2 show the retrieval of the documents for the sample query "program" when contextual information has not been used.  ...

Probabilistic model for contextual retrieval

Ji-Rong Wen, Ni Lao, Wei-Ying Ma
2004 Proceedings of the 27th annual international conference on Research and development in information retrieval - SIGIR '04  
We observed that incompatible context, noisy context and incomplete query are several important issues commonly existing in contextual retrieval applications.  ...  In this paper, we propose probabilistic models to address these problems. Our study clearly shows that query log is the key to build effective contextual retrieval models.  ...  By using these document terms to expand the original queries, it is expected to retrieval good documents matching the information need represented by both query and context.  ...
