PURPOSE:To rapidly retrieve a meaning network by executing retrieval processing based upon an associative memory and retrieval processing based upon an is-a memory in parallel. CONSTITUTION:In addition to the associative memory 3 for storing object- attribute-value, the is-a memory for independently storing is-a attribute in the memory 3 is provided. As to a question, 'What does CLYDE has?', the contents following CLYDE are retrieved from the is-a memory 4 in parallel with the retrieval of contents indicating that the object is 'CLYDE' and the attribute is 'has' from the memory 3. Since 'ROBIN' and 'BIRD' are retrieved from the memory 4 through the memory 3 has no object, these data are successively inputted to a queuing buffer 5, and when the memory 3 is retrieved by using the data as the object, 'WING' corresponding to 'BIRD' can be retrieved.
