Knowledge transformations between frame systems and RDB systems

For decades, researchers in knowledge representation (KR) have argued for and against various choices in KR formalisms, such as Rules, Frames, Semantic nets, and Formal logic. In this paper, we present a set of transformations that can be used to move knowledge across two fundamentally different KR formalisms: Frame-based systems and Relational database systems (RDBs). We also describe partial implementations of these transformations for a specific pair of such systems: Protégé and the Postgres RDB system. Categories and Subject Descriptors I.2.4 Knowledge Representation Formalisms and Methods – representation languages General Terms Algorithms, Performance, Design. Keywords Knowledge interoperation, knowledge transformation.
