Enterprise computing is marked by large-scale information systems, such as databases, document management, and groupware that present significant obstacles to consistent cross-application use: dissimilar user interfaces, incompatible security schemes, and the undesirable property of serving only parts of the user community (islands of use) and accessing only some of the enterprise knowledge assets (islands of information).World Wide Web (WWW) architectures do not solve this problem directly. WWW software components are combinable in many clever ways but until recently there were no specific efforts to solve the enterprise computing problems of islands of use and information.The situation is changing now with nascent efforts to architect Web Portal systems with small software modules, for example with Java "portlets" or the Python-based Zope framework [15]. These are program-centric approaches to coalesce information sources and unify the query interface without inherent user modeling. This paper discusses in detail an alternative: a user-centered, conversational portal which extends the ALICE chatbot technology platform and links the user conveniently to information resources, such as Web Services, with specialized query routing. The approach offers scalability, extensibility, and coordination between end-users and developers. A university Intranet implementation, the Catacomb system, is presented and discussed to illustrate the advantages of the conversational Web portal approach.
