Towards an intelligent information system

Xiaofei JiaMengchi Liu

Nowadays, information overload is becoming an ever-growing problem. Finding the exact information is quite difficult. The main problem is that information is not organized according to its natural structures. There is not a data model that can represent these semi-structured or unstructured data in a natural way. On the other hand, almost every information application exploits interactive interfaces in some way. However, the development of user interfaces is still ad-hoc and often uses some predefined form-based interfaces. How can users express their queries in a semantic way is an important research topic. In this paper, we present an effective conceptual model to organize data according to their contents based on object-relation databases, and describe a quasi-natural language interface for the conceptual model. We also discuss the design and implementation of our prototype system.
