Abstract: A data base system that supports natural language queries is not really natural if it requires the user to know how the data are represented. This paper defines a formalism, called conceptual graphs, that can describe data according to the user’s view and access data according to the system’s view. In addition, the graphs can represent functional dependencies in the data base and support inferences and computations that are not explicit in the initial query.IBM Journal of Research and Development 20:4, pp. 336-357.

This paper describes a computer system for understanding English. The system answers questions, executes commands, and accepts information in an interactive English dialog. It is based on the belief that in modeling language understanding, we must deal in an integrated way with all of the aspects of language—syntax, semantics, and inference. The system contains a parser, a recognition grammar of English, programs for semantic analysis, and a general problem solving system. We assume that a computer cannot deal reasonably with language unless it can understand the subject it is discussing. Therefore, the program is given a detailed model of a particular domain.

Among the largest university presses in the world, The MIT Press publishes over 200 new books each year along with 30 journals in the arts and humanities, economics, international affairs, history, political science, science and technology along with other disciplines. We were among the first university presses to offer titles electronically and we continue to adopt technologies that allow us to better support the scholarly mission and disseminate our content widely. The Press's enthusiasm for innovation is reflected in our continuing exploration of this frontier. Since the late 1960s, we have experimented with generation after generation of electronic publishing tools. Through our commitment to new products--whether digital journals or entirely new forms of communication--we have continued to look for the most efficient and effective means to serve our readership.
