Query Expansion in Information Retrieval Systems using a Bayesian Network-Based Thesaurus
[article]
2013
arXiv
pre-print
Preserved Fulltext
In this paper we develop a method of query expansion based on Bayesian networks. ...
Using a learning algorithm, we construct a Bayesian network that represents some of the relationships among the terms appearing in a given document collection; this network is then used as a thesaurus ...

We review the application of Bayesian belief networks to several information retrieval problems, showing that they provide an effective and flexible framework for modeling distinct sources of evidence ...
Using this idea, we now show how to extend the Bayesian network model to allow combining distinct sources of evidential information obtained from a juridical thesaurus, 9 for information retrieval of ...
