The design consists of three independent modules, namely the Natural Language Processor, the Expert System for query analyzing and result outputting, and the Database Management module (query execution module). These modules interact with each other through shared data and storage areas. The thesis emphasizes the integration of an expert system with a database management system to retrieve multimedia data stored in the database. At this stage of the development, all the three modules can interact with each other. The input to the system is a query in English for retrieving the data from the database. The system can check the syntax and semantics of the input queries, generate as well as execute equivalent database queries, and produce adequate results. The Natural Language Interface and the query and result analyzers are written in MPROLOG on a SUN workstation, whereas the database software module is written in C with embedded SQL commands for retrieving the data managed by ORACLE Relational DBMS. Examples of data modeling and the system organization are discussed and some sample runs are illustrated.135 p.Engineering, Electronics and Electrical.Thesis
