Implementation of An Information Extraction System using Boolean Model

Abstract

The rapid growth of on-line information has created a surge of interest in tools that are able to extract information from on-line documents. Information extraction (IE) is the process of pulling desired pieces of information out of a document. IE systems are complementary to Information Retrieval (IR) systems and can make information retrieval more precise. This system intends to implement an information extraction system using Boolean Model and it will display the relevant information according to user's preference. Boolean model was the first operational Information Retrieval model. It has the advantages of ease and efficiency of the implementation, simplicity of the inverted file structure, and clarity of the model. In Boolean Model, user's request is converted to Boolean algebra (i.e., 0 and 1) and Boolean queries give inclusion or exclusion of documents. As a case study, this system will implement based on sale system of computer and accessories.
