Query Expansion Using Augmented Terms in an Extended Boolean Model
We propose a new query expansion method in the extended Boolean model that improves precision without degrading recall. For improving precision, our method promotes the ranks of documents having more query terms since users typically prefer such documents. The proposed method consists of the following three steps: (1) expanding the query by adding new terms related to each term of the query, (2...
متن کاملAn investigation of query expansion terms
This poster describes a framework for investigating the effectiveness of query expansion term sets and reports the results of an investigation on the quality of query expansion terms coming from different sources: pseudo-relevance feedback, webbased expansion, interactive elicitations from the user searchers, and expansion approaches based on query clarity. The conclusion regarding the experime...

Experiments with Automatic Query Formulation in the Extended Boolean Model
This paper concentrates on experiments with automatic creation of queries from natural language topics, suitable for use in the Extended Boolean information retrieval system. Because of the lack and/or inadequacy of the available methods, we propose a new method, based on pairing terms into a binary tree structure. The results of this method are compared with the results achieved by our impleme...
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 ...
