The system described in this report is designed for use as a computational tool that allows a linguist to develop and study methods for generating surface strings from an underlying semantic structure. Initial findings with regard to form-determiners (such as voice, form, tense, and mood), some rules for embedding sentences, and some attention to…

This report describes work on a pilot system for a fully automatic, high-quality translation of German scientific and technical text into English and gives the results of an experiment designed to show the system's capability to produce quality mechanical translation. The areas considered were: (1) grammar formalism, mainly involving the addition…

At present a computer system cannot be constructed for handling the totality of a natural language in any significant way. It is, however, possible to construct a system for communication in a narrow field of discourse. A working model for a specialized discourse based on a recognition grammar is discussed. Some properties of the recognition…

A set of procedures for testing hypotheses about the syntactic structure of natural languages has been developed for use on-line with computer display consoles. The procedures were designed in the context of Chomsky's transformational generative grammar. A linguist can construct phrase structure trees, selecting with the lightgun from alternative…

This paper describes the notation and underlying organization of an augmented, recursive-transition network grammar and illustrates how such a grammar is a natural medium for expressing and explaining a wide variety of facts about the psychological processes of sentence comprehension. A general discussion of transformational grammar and…

There is a need for a new kind of linguistic theory which, while being concerned with both generation and analysis, must include the roles of memory, non-linguistic knowledge, and inference. The role of logic is diminished according to such a theory because inference has no real logical content. Meaning must be studied with respect to the actual…

This paper describes a system for the computer understanding of English. The system answers questions, executes commands, and accepts information in normal English dialogue. It uses semantic information and context to understand discourse and to disambiguate sentences. It combines a complete syntactic analysis of each sentence with a heuristic…

The final part of a four-part report of research on the development of a computerized, phrase-structure grammar of modern Hebrew describes the computerized algorithm for analyzing the sentences generated based on a complex-constituent-phrase structure grammar. The first section here discusses a structural model for modern Hebrew; the second…

This discussion of the use of computer programming in syntactic analysis covers three major points: (1) a review of basic notions in automatic grammars; (2) a description of the grammar used in a pilot project which analysed the linguistic content of methods of teaching foreign languages; and (3) proposals on the application of the same techniques…

This first part of a four-part report of research on the development of a computerized, phrase-structure grammar of modern Hebrew presents evidence to demonstrate the need for material to train teachers of Semitic languagues in the theory of grammar. It then provides a discussion of the research already done on the application of computational…

The second part of the four-part report of research on the development of a computerized, phrase-structure grammar of modern Hebrew describes the application of a generalized complex-constituent-phrase structure grammar to modern Hebrew. This volume discusses the details of the grammar: limitations, input and output, symbols, rules, tree diagrams,…
