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…

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…

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)

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…

Specific aspects of the thesaurus treated in this brief review are: thesaurus as a concept, classification and structure, and language compilation and control. (75 references) (NH)

INDEX, an interactive retrieval program developed at Pepperdine University, is described. It is easy to use and maintain, locates sources of information from a general description of the information needed, requires only a modest investment of time, and is widely applicable. (MLW)

The Computer Assisted Reference Locator (CARL) is a computer-based information retrieval system which uses coordinate indexing. Objectives established in designing the system are: (1) simplicity of reference query and retrieval; (2) ease of system maintenance; and (3) adaptability for alternative computer systems. The source documents input into…

Presents three different statistical techniques for identifying content-bearing phrases within a natural language database. Describes results on the effectiveness of the scoring methods when applied to MEDLINE phrases, and how the three methods can be combined to improve performance. Processing results for an example document are provided.…

This report on the multidisciplinary PASCAL database describes the files and the indexing rules for chemistry, biology, and medicine. PASCAL deals with all aspects of chemistry within two subfiles whose combined yearly growth is about 100,000 references. The Biopascal file, organized in the two subfiles of Plant Science and Biology and Medicine,…

The report summarizes work done in the study of measures for the effectiveness of the performance of large file systems. It consists of six sections: An "Introduction and Summary" which describes the background for the study, the approach taken in it, and summarizes the results; A discussion of the "Forms of Input", which characterizes the basic…
