    The efficacy of expert systems often depends on the accuracy and completeness of the problem specification negotiated with the user. Therefore, efficient user interfaces are needed, in order to assist the user in identifying and supplying the required data. Our approach presented in this paper is based on the utilisation of conversational interfaces, giving users the possibility of interacting with the system by means of natural language. Through the use of flexible dialogue management plans and an advanced problem solving strategy based on case based reasoning and information retrieval, efficient user guidance during the interaction with an expert system can be achieved. Thus, the user can interactively develop a comprehensive and coherent specification of his problem, based on clarifications, explanations, and context-based factual information provided by the system. As an application framework we introduce the EU-funded Project VIP-Advisor whose objective is the development of a virtual insurance and finance assistant capable of natural language interaction.

    In contrast to electronic document collections we find in contemporary digital libraries, systems applied in the cultural domain have to satisfy specific requirements with respect to data ingest, management, and access. Such systems should also be able to support the collaborative work of domain experts and furthermore offer mechanisms to exploit the value-added information resulting from a collaborative process like scientific discussions. In this paper, we present the solutions to these requirements developed and realized in the COLLATE system, where advanced methods for document classification, content management, and a new kind of context-based retrieval using scientific discourses are applied.
