English Abstract

The motive of this thesis is the desire to facilitate Information Retrieval Technology based on user profile and context, by using approaches and operators used in the field of Information Retrieval technology.

This thesis presents the design and implementation of a knowledge-based system for text retrieval.

The system based on specific knowledge in the field of search technique and access to all information on the World Wide Web (www).

The specific knowledge in this system as its knowledge base lead to the possibility of achieving the linking process between the searching texts entered by the user into the system and his interest areas together with the key words.

The system consists of five parts; these are user interface, knowledge-base, inference engine, user profile as a database, and the search engine.

The proposed approaches for retrieving information from the World Wide Web through the most popular search engines GOOGLE and YAHOO, the proposed approaches work to retrieve information by creating a database that represents the user profile which contains a set of keywords to represent user areas interest, connects these keywords with search keyword or keywords in the search text box by using an appropriate Boolean operator.

That is lead to generate context to help search engines to retrieve useful information from the World Wide Web.

The methodology used in this thesis is analytical and empirical methodology, analytical because it based on litterateur scurvies deal with IR technology and depend statistical studies on non-random sampling from society interested with this topic.

This study empirical study because need to implement an application to achieve the proposed approach Usually when there are many key words for searching about particular information the search technique will be slow since there are many relationships between each key word with the other two concepts which are user prior knowledge and user profile.

The proposed system, to implement this proposed approach, is a windows application uses Visual BASIC.NET 2010, to design user interface, In addition to the use of SQL Server 2008 software to build a database store each user profile.

The proposed system can be as a facility available in the search engines in order to help naive users.

The proposed method facilitates the user for retrieving information just within their areas of interest, reducing the number of sites that appear to the user on web browser and reducing the number of keywords entered by the user in the search text box.

Keywords : Boolean Operators, Context, Information Retrieval Technology, Knowledge Based System, Knowledge Representation, Search Engine, Searching Techniques, User Profile, Web Information Retrieval, World Wide Web.
