Towards a data model for artificial intelligence applications

Data models used in database management have not been built with AI applications in mind. The entities and their relationships in an AI environment transcend in complexity the data semantics of most other databases, so that the expressive power of the "usual" data models becomes insufficient. In AI community databases are viewed as a possible application area ("database front ends") but in AI research itself the databases used tend to be ad hoc and are not specified in terms of data models and DBMS based on such. The data model suggested below is a step towards bridging the gap between database theory and AI databases.
