  • Patent number: 5473732
    Abstract: A relational artificial intelligence system is invented and developed. It comprises a relational automatic knowledge acquisition system and a relational reasoning system. The relational automatic knowledge acquisition system is a relational learning system which discovers knowledges from spreadsheet-formed databases and generates relational knowledge bases using inductive learning technique. The relational reasoning system is a relational knowledge-based system which reasons about the generated relational knowledge bases automatically and predicts what will happen under future data readings. The feature of this invention is that every component in this system is relational. Not only the database to be read and the knowledge base to be generated, but also the inductive engine and the inference engine are relational. In the whole reading, operating, and generating processes, data are organized in the spreadsheet-form, and hence the system works with high efficiency and speed.

  • Patent number: 5263126
    Abstract: A user-friendly expert system with new types of knowledge bases is disclosed. The major new components in the invented expert system are: A stored knowledge base in the form of an array, an input knowledge base in the form of a truth table or in some other user-defined forms, a transfer engine being a built-in computer program transferring the input knowledge base to the stored knowledge base, and an automatic inference engine being a built-in computer program reasoning with the stored knowledge base by a double loop. No matter what the size of the input knowledge base is, and no matter what the size of the input knowledge base is, and no matter what kind of knowledge is stored in it, the double loop always processes the inference automatically, and no compilation is necessary. Therefore, the inference engine is called the automatic inference engine and the system is called the automatic expert system.
