Making Information Sources Available for a New Market in an Electronic Commerce Environment
نویسنده
چکیده
Literature search and delivery in the World Wide Web is a rapidly expanding market. Up to now the search is mostly cost-free. But in the future we expect the appearance of more and more providers charging for their services. The main problems are finding the right provider and extracting the information. In this paper we present a system for intelligent information search and extraction from multiple provider’s Web sites. One important part of the system is the so-called wrapper. In this paper, we present the architecture of these wrappers. Their task is the translation of a customer’s query into the sources syntax and the re-translation of the answer. Applying these wrappers in an electronic commerce environment needs additional functionality, e.g., navigation through a providers site, collection of the information the customer desires or precalculation of costs. Because of the variety of the sources functionality, we need a flexible and individually built wrapper. This could be achieved using a modular concept.
