Practical Development of Internet Prolog Applications using a Java Front End

: This paper introduces a general architecture that could be employed to many Prolog applications to make them available on the Internet. The approach presented makes use of client-server architecture where the client is a relatively intelligent front end written in Java, and the server is the Prolog based application. Two applications developed using this architecture: an intelligent image retrieval application, and a toy expert system, are discussed. Keywords: Prolog, Java, Client-server architectures, Hierarchical Classification, Expert Systems, Internet applications. Introduction The widespread use of the Internet and the World Wide Web has motivated much work with the aim of providing interactive applications on the Internet. Sun's Java[ Java97], Netscape plug-ins [BuPlg97], and Microsoft's ActiveX[ActX97] are perhaps the most famous of these endeavors. In order to support this new technology, Internet browsers, and tools have undergone numerous evolutions. These advances have m..
