Earl, Lois L. – Information Storage and Retrieval, 1972
This paper describes how the problem of resolution of syntactic ambiguities is approached in the parser PHRASE, developed for use in experiments in automatic indexing and extracting. PHRASE is a multi-level parser for declarative sentences, in which the syntactic structure is built up in four stages. (10 references) (Author)

Illinois Univ., Urbana. Coordinated Science Lab. – 1969
In contrast to conventional information storage and retrieval systems in which a body of knowledge is thought of as an indexed codex of documents to which access is obtained by an appropriately indexed query, this interdisciplinary study aims at an understanding of what is "knowledge" as distinct from a "data file," how this knowledge is acquired,…

Herman, L. Russell, Jr. – 1975
When a grammar is expressed in augmented transition network (ATN) form, the problem of detecting syntactic ambuguity reduces to finding all possible paths through the ATNs. Each successfully terminating path through the ATN generates an acceptable parsing of the input string. Two ATN forms, minimal-node and pseudo-tree, are described along with…

Wilks, Yorick – 1975
The paper surveys the major projects on the understanding of natural language that fall within what may now be called the artificial intelligence paradigm of natural language systems. Some space is devoted to arguing that the paradigm is now a reality and different in significant respects from the generative paradigm of present-day linguistics.…

Chafe, Wallace L. – 1974
The report documents performance on a 24-month R&D effort oriented toward the development of a computerized model for machine translation of natural languages. The model is built around a set of procedures called verbalization, intended to stimulate the processes employed by a speaker or writer in turning stored information into words.…

Kaplan, Ronald M. – 1971
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…

Ahmad, K.; And Others – Association for Literary and Linguistic Computing Bulletin, 1978
Some of the problems facing undergraduates learning Russian can be dealt with effectively by using an online computer. A Russian numerals drill program (RUNEX) is described which aims to help the student in tackling the morphological arbitrariness and some aspects of the syntax of the Russian numerals. Paradigms are given for the numerals five,…

Ornan, Uzzi – Association for Literary and Linguistic Computing Bulletin, 1978
The ability of the computer to generate output not included in the input may be used for linguistic as well as for computational input. The ability to accept linguistic data and process it according to a certain program seems to be a promising field for investigation. Progress in this field may strengthen the assumption that the computer can be…

Mepham, Michael S. – 1967
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…
