Bring Intelligence to Object-Embedded Documents Using PrologScrip Language

Abstract

Nowadays, it is not uncommon that a web page includesmany ActiveX controls and/or applets, which are controlled viavarious scripts coming with the page. Besides reducing Internet traffic, this also makes the page more actice and enhances software reusability. Two leading scripting languages are VBScript, which was provided by Micorsoft, and Javascript, which was provided by Netscape. Suchprocedural language, however, are inappropriate in AI (artificial intelligence) programming. To apply AI technology into Web, we develop the so-called PrologScript language. This allows Web page designers to embed rules into documents and, as a result, meke controls in documents, seemingly, intelligent. This research is based on COM(Component Object Model) model and ActiveX Scripting technology. In this paper, we'll describe the architecture of a scripting engine and its counterpart, say, scripting host. In addition, we highlight the strategy of building a scripting engine using available programming environment in a locla system. Twoconcrete examples are given to manifest the feasibility of using PrologScript to bring intelligence into object-embedded documents.
