Since natural language may be assumed to have an underlying conceptual structure, it is desirable to have the machine structure its own experience, both linguistic and nonlinguistic, in a manner concomitant with the human method for doing so. This paper presents some attempts at organizing the machine's information conceptually. The different systems discussed include Deese's Categorical Dictionary, Salton's SMART, Wood's Question-Answering System, Quillian's Semantic Memory, the DEACON System, and Schank's Conceptual Dependency. The attempts are discussed and coordinated into a framework for what may be a practicable system. (Author/BB)
