How lexical information should be formulated, and how it is organized in computer memory for rapid retrieval, are central questions for computational linguists who want to create systems for language understanding. How lexical knowledge is acquired, and how it is organized in human memory for rapid retrieval during language use, are also central questions for cognitive psychologists. Some examples of psycholinguistic research on the lexical component of language are reviewed with special attention to their implications for the computational problem. . | DICTIONARIES OF THE MIND George A. Miller Department of Psychology Princeton University Princeton NJ 08544 USA ABSTRACT How lexical information should be formulated and how it is organized in computer memory for rapid retrieval are central questions for computational linguists who want to create systems for language understanding. How lexical knowledge is acquired and how it is organized in human memory for rapid retrieval during language use are also central questions for cognitive psychologists. Some examples of psycholinguistic research on the lexical component of language are reviewed with special attention to their implications for the computational problem. INTRODUCTION I would like to describe some recent psychological research on the nature and organization of lexical knowledge yet to introduce It that way as research on the nature and organization of lexical knowledge usually leaves the Impression that It Is abstract and not very practical. But that Impression Is precisely wrong the work Is very practical and not at all abstract. So I shall take a different tack. Computer scientists those in artificial Intelligence especially sometimes Introduce their work by emphasizing its potential contribution to an understanding of the human mind. I propose to adopt that strategy in reverse to introduce work in psychology by emphasizing Its potential contribution to the development of information processing and communication systems. We may both be wrong of course but at least this strategy Indicates a spirit of cooperation. Let me sketch a general picture of the future. You may not share my expectations but once you see where I think events are leading you will understand why I believe that research on the nature and organization of lexical knowledge Is worth doing. You may disagree but at least you will understand. Some Technological Assumptions I assume that computers are going to be directly linked by communication networks. Even now In local area networks a .
