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.
