Query Expansion using an Automatically Constructed Thesaurus
نویسنده
چکیده
Our group participated in the Japanese and English Retrieval Subtasks of TCIR-6. Our goal was to evaluate the effectiveness of a thesaurus constructed from patents for invalidity search. To confirm the effectiveness of our thesaurus-based query expansion, we conducted experiments and found that our method can improve upon traditional document retrieval systems.

Ad Hoc Retrieval Experiments Using WordNet and Automatically Constructed Thesauri
This paper describe our method in automatic-adhoc task of TREC-7. We propose a method to improve the performance of information retrieval system by expanded the query using 3 di ferent types of thesaurus. The expansion terms are taken from handcrafted thesaurus (WordNet), co-occurrence-based automatically constructed thesaurus, and syntactically predicate-argument based automatically constructe...
متن کاملCombining General Hand-Made and Automatically Constructed Thesauri for Query Expansion in Information Retrieval
One of the most intuitive ideas for enhancing the effectiveness of an information retrieval system is to include the use of a thesaurus. WordNet, as a hand-crafted and general-purpose thesaurus, intuitively should also work fine in information retrieval, but unfortunately, experimental results by many researchers have not been promising. Thereby in this paper we investigate why the use of WordN...
متن کاملRegression Model and Query Expansion for NTCIR-2 Ad Hoc Retrieval Task
This paper describes procedures and results in a monolingual retrieval experiment using NTCIR-2 test collection. First, we discuss a simplified logistic regression model, which enable us to adjust the regression model for working well in each of various document databases. To do automatically the adjustment, a method for estimating parameters in the regression model, is developed based on a kin...
متن کاملQuery Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...
متن کاملSimilarity Thesauri and Cross-Language Retrieval
This paper describes a method for constructing a thesaurus automatically from a corpus of suitable documents, using standard information retrieval methods. The resulting thesauri can be used for user-initiated query expansion, automatic query expansion, as well as cross-language retrieval. Researchers at the Swiss Federal Institute of Technology in Zürich developed and evaluated this method in ...
