Decisions in thesaurus construction and use

Robert M. Losee
2007 Information Processing & Management  
A thesaurus and an ontology provide a set of structured terms, phrases, and metadata, often in a hierarchical arrangement, that may be used to index, search, and mine documents.  ...  These decisions may be used in the automatic construction of a thesaurus. The evaluation of an existing thesaurus is described, consistent with the decision criteria developed here.  ...  Thesaurus construction and use serve as fundamental functions within the fields of text mining and information retrieval.  ...

An approach to automated thesaurus construction using clusterization-based dictionary analysis

Nadezhda Lagutina, Ilya Paramonov, Inna Vorontsova, Natalia Kasatkina

Thesaurus based automatic keyphrase indexing

Olena Medelyan, Ian H. Witten
2006 Proceedings of the 6th ACM/IEEE-CS joint conference on Digital libraries - JCDL '06  
We propose a new method that enhances automatic keyphrase extraction by using semantic information on terms and phrases gleaned from a domain-specific thesaurus.  ...  Keyphrases are widely used in both physical and digital libraries as a brief but precise summary of documents.  ...  remaining terms to their grammatical roots § sort them into alphabetical order.  ...

Ensemble methods for automatic thesaurus extraction

James R. Curran
2002 Proceedings of the ACL-02 conference on Empirical methods in natural language processing - EMNLP '02  
However, their results are limited by the simplicity of their evaluation task and individual classifiers.  ...  Our work explores ensemble efficacy for the more complex task of automatic thesaurus extraction on up to 300 million words.  ...  Acknowledgements We would like to thank Miles Osborne for initial discussions which led to this work, and Marc Moens, Steve Finch and Tara Murphy for their feedback on drafts of this paper.  ...
