Recognition and separation of sounds played by various instruments is very useful in labeling audio files with semantic information. This is a non-trivial task requiring sound analysis, but the results can aid automatic indexing and browsing music data when searching for melodies played by user specified instruments. Melody match based on pitch…

An operational, comprehensive, economical method for updating and correcting entries in a computerized bibliographic system is presented. The technique was developed in connection with the East African Agricultural Bibliographic Project at West Virginia University. Data modification operations are discussed as well as the limitations of the method…

Holds that database producers and online system vendors have failed to maintain sufficient quality control over their products, and that online searchers should voice their complaints about file documentation errors, indexing inconsistencies, and incorrect data entries. (FM)

Progress is reported at the 1,000,000 word level on the development of a partial syntatic analysis technique for indexing text. A new indexing subroutine for hyphens is provided. New grammars written and programmed for Machine Aided Indexing (MAI) are discussed. (ED 069 290 is a related document) (Author)

Indexing and abstracting can be thought of as a way of modeling an actual document or textual item. Both are miniature versions of the actual thing. Normally, the indexing model is used to locate desired information, while the abstracting model is used as a screening medium to help the searcher decide which of the apparently correct actual items…

The only paper printed in full in this digest is the Miles Conrad Memorial Lecture given by Dr. Burton W. Adkinson entitled: "After Organization X - What Next?" Dr. Adkinson reviews a national plan for abstracting and indexing services proposed by Robert Heller and Associates in the early sixties, in the light of the current requirements…

A survey of automatic indexing systems and experiments has been conducted by the Research Information Center and Advisory Service on Information Processing, Information Technology Division, Institute for Applied Technology, National Bureau of Standards. Consideration is first given to indexes compiled by or with the aid of machines, including…

This discussion of the general principles of structure and construction of numeric databases introduces the concept of data points, their relationship to each other, and their storage in a nonredundant way. The collection of numeric data and their integration into the database structure are explained. Eight references are cited. (EJS)

A model computer-assisted information retrieval system was developed to explore techniques for electronic searching of music education data. The list of concepts was collected from existing indexing services, including the Music Index, Reader's Guide to Periodical Literature and the Thesaurus of ERIC Descriptors. (Authors/CB)

This review of the Keyword-in-Context (KWIC) indexing considers its inception by Luhn, its original format and purpose, various applications and uses of the basic KWIC concept, its advantages and disadvantages, and evaluations of its effectiveness. (30 references) (Author/NH)

The Multiterm system is shown to be a unique concept for producing a multilingual index via computer processing. The new concept has significance for international cooperative programs. (6 references) (Author/NH)

Reports on a series of programs that have been developed to process data bases, consisting of textual items, and to index and arrange (classify) the data items in accordance with an automatically generated classification system. (Author)

Working toward the goal of an automatic indexing system which is truly competitive with human indexing in cost, time and comprehensiveness the Machine-Aided Indexing (MAI) process was developed at the Defense Documentation Center (DDC). This indexing process uses linguistic techniques but does not require complete syntactic analysis of sentences…

The characteristics of the Intrex subject/title inverted file are analyzed. Basic statistics of the inverted file are presented including various distributions of the index words and terms from which the file was derived, and statistics on stems, the file growth process, and redundancy measurements. A study of stems both with extremely high and…

A formula is given that enables one to determine the parameters for amortizing an information system within a year. The formula is illustrated with three mechanized information systems for patents. The most critical parameter is shown to be indexing time. (7 references) (Author/NH)
