A Semantic Analysis of Abstracts Around an Experiment in Mechanized Indexing.
Noel, Jacques
The first part of this dissertation is a metatheoretical discussion of the needs and means of semantic analysis. This discussion includes sections on metalanguage, deep and surface structure and structural semantics, and procedures for relating the English of abstracts to a classification concordance in the same language. The second part describes the experiment, in which a mechanized indexing system was developed and applied to 50 abstracts from a bibliography on documentation. In this system, each text word or symbol is replaced by a code, after which the machine performs step-by-step concatenations, rewriting two or more codes as a single code, until each abstract is rewritten as a single code. Part three is a discussion of problems of semantic representation in: (1) theoretical background--constituent-structure rules, lexical entries, and conjunction, discourse and relative clauses; (2) expressions such as "a discussion of..." and "this paper discusses..." (3) conjunction, relative changes and presupposition; (4) asymmetric conjunction--proposes an analysis in terms of case theory; and (5) examples drawn from the corpus that present difficulties for current case theory (for example, "as machines learn..."). The appendices contain descriptors, sample abstracts, and other material used in this study. A 14-page bibliography concludes the work. (KM)
