Advanced Information Retrieval Web Services for Digital Libraries

Web service, as a standardized XML-based protocol, has been useful for inter-system communication and integration. However, web services in the IR domain have not been widely used. In a previous paper [2], we discussed our implementation of an information retrieval (IR) function called LUCAS, a web service for extracting, weighing, and ranking terms. It properly demonstrated adaptability and accessibility of web services in IR. In this paper, we are going to discuss a more advanced version developed recently called Lucas II. This updated implementation includes functions of term generation, clustering, and document classification that can be operated in different knowledge domains.
