Exploiting External Collections for Query Expansion

Wouter Weerkamp, Krisztian Balog, Maarten de Rijke
2012 ACM Transactions on the Web  
In this article we propose a general generative query expansion model that uses external document collections for term generation: the External Expansion Model (EEM).  ...  The main rationale behind our model is our hypothesis that each query requires its own mixture of external collections for expansion and that an expansion model should account for this.  ...  ACKNOWLEDGMENTS We are grateful to our reviewers and the editors of the journal for providing valuable comments and feedback, helping us to improve the quality of this article.  ...

We also used some API functions of Lemur for index accessing.  ...

Automatic query expansion based on tag recommendation

Vitor Oliveira, Guilherme Gomes, Fabiano Belém, Wladmir Brandão, Jussara Almeida, Nivio Ziviani, Marcos Gonçalves
2012 Proceedings of the 21st ACM international conference on Information and knowledge management - CIKM '12  
Recently, some query expansion techniques exploit external sources of information found on the Web, such as on-line encyclopedias and collaborative social annotation systems, to select semantically rich  ...  They select expansion terms from highly ranked documents retrieved as result of the original query, assuming that these documents contain useful terms for query expansion.  ...  There have also been some proposals to exploit external sources of information for query expansion. For example, [Cui et al., 2003] proposed a query expansion approach based on mining user logs.  ...

Modelling the Usefulness of Document Collections for Query Expansion in Patient Search

Nut Limsopatham, Craig Macdonald, Iadh Ounis
2015 Proceedings of the 24th ACM International on Conference on Information and Knowledge Management - CIKM '15  
Existing work used query expansion (QE) to extract expansion terms from different document collections to improve query representation.  ...  In this work, we investigate two automatic approaches that measure and leverage the usefulness of document collections when exploiting multiple document collections to improve query representation.  ...  In this work, we use both the targeted and external collections to expand a query.  ...

An Augmented User Model for Personalized Search in Collaborative Social Tagging Systems

Wenyu Zhao, Dong Zhou, Xuan Wu, Séamus Lawless, anxun Liu
2017 EAI Endorsed Transactions on Collaborative Computing  
We further present a new query expansion method to facilitate the desired personalized retrieval.  ...  These resources are further processed according to the user's past information by exploring external knowledge base. A novel generative model is proposed for user model generation.  ...  Though LM+RM-wiki method exploited external knowledge base, this methods was based on the feedback documents, which can't supply enough information to term expansion sets.  ...

Wikipedia pages as entry points for book search

Marijn Koolen, Gabriella Kazai, Nick Craswell
2009 Proceedings of the Second ACM International Conference on Web Search and Data Mining - WSDM '09  
We experiment with traditional query expansion techniques, exploiting Wikipedia articles as rich sources of information that can augment the user's query.  ...  Search engines, such as Google Books, provide mechanisms for searchers to enter this vast knowledge space using queries as entry points.  ...  ., in [20] , for example, exploit Wikipedia as an external corpus to expand poor performing queries in the TREC Robust track.  ...

Using Meda-data to Search for Clinical Records: RMIT at TREC 2012 Medical Track

Iman Amini, Mark Sanderson, Xiaodong Li, David Martínez
2012 Text Retrieval Conference  
In this paper we propose a novel approach to locally build a knowledge source from the existing data set to be used for query expansion, exploiting the ICD codes.  ...  While this approach does not rely on any external knowledge sources, it proves to be significantly superior to our global expansion and baseline systems.  ...  The local expansion methods exploit terms only from the underlying collection, while global methods can extract information from external knowledge sources as well.  ...
