Nowadays,information overload is becoming an ever-growing problem. As a result,finding the exact information is quite difficult. One major reason is that the information is not organized according to its natural structures. There is not a data model that can represent unstructured or semi-structure data in a natural way. Moreover,almost every information application exploits interactive interfaces that are still ad-hoc. Therefore,how users express their queries in a semantic way is an important research topic. This thesis presents the design of an effective conceptual model to organize information according to its natural structures,based on object-relation databases,and describes a quasi-natural language interface for the conceptual model. It discusses the design and implementation of our prototype system.
