AUTOMATIC INDEXING AND ABSTRACTING, PART 1
Abstract
The report consists of 8 papers. The first four papers are concerned with the relationship between the part of speech of words and their graphic form. An operational definition of affixes is given, the usefulness of affixes in the automatic determination of parts of speech is discussed, and an algorithm is outlined for determining parts of speech with a dictionary look-up of less than 200 affixes and less than 800 words. The inflection of adjectives is also discussed, anticipating the need for future refinement of the part-of-speech algorithm, which at present identifies 11 part-of-speech categories. The fifth paper is a progress report on the development of a method for automatic indexing without reference to any pre-prepared dictionary, thesaurus, etc. It shows the current results on five text excerpts. The final three papers are concerned with the relationship between English phonetics and English morphology. One of the papers is concerned with homonyms, which represent a problem area in transformation from phonetic to graphic English. Another discusses a function for mapping written English into spoken English, and the third describes a computerized study of transcribed English phonetics as given by different dictionaries.
