Meta-analysis is a technique used in a variety of disciplines to combine and summarize the findings of previous research. One step in the production of a meta-analysis is a thorough literature search for relevant studies. A variety of methods can be used to increase the number of studies that are found. This study examines the extent to which some…

Presents criteria for an effective syntagmatic relator system and describes how conceptual syntagmatic relationships are expressed in natural language, commenting on the adequacy of such expressions for document retrieval systems. Only one type of expression, a gestalt structure, represented as a frame, conforms to the criteria. (Author/JKP)

Documentation centers are needed to handle the vast amount of scientific and technical information currently being issued. Such centers should be concerned both with handling inquiries in a particular field and with producing a general catalog of current information. Automatic analysis of texts by computers will be the best way to handle material,…

THIS APPENDIX TO THE FINAL REPORT OF THE AIP/UDC PROJECT (LI 000 583) INCLUDES THE COMPLETE, MERGED SET OF UDC SCHEDULES ACCUMULATED BY THE AIP/UDC PROJECT FROM 1965-1967. PART 1 OF THE FILE CONTAINS 110,759 RECORDS. EACH RECORD INCLUDES THE UDC NUMBER, A CODE WHICH REPRESENTS THE SOURCE OF THE RECORD, AND THE ENGLISH LANGUAGE EQUIVALENT OF THE…

Investigates the presence of clustering structure in a document collection and the influence of the presence of clustering structure on the success of cluster-based retrieval. Term-weight and similarity thresholds are discussed, empirical and statistical significance are considered, and indexing exhaustivity for document representation is…

THE AVAILABILITY OF STUDENTS AT THE UNIVERSITY OF DAYTON HAD SUGGESTED THEIR POSSIBLE USE AS INDEXERS FOR INDEXING DOCUMENTS FOR THE AEROSPACE MATERIALS INFORMATION CENTER (AMIC). A STUDENT HAD BEEN EMPLOYED TWO YEARS AGO AND INFORMALLY TRAINED IN INDEXING. THE SUCCESS OF THAT EXPERIENCE, THE SUCCESSFUL DEVELOPMENT OF A CONTROLLED VOCABULARY, AND…

An experiment to compute and analyze the degree of association between descriptors used to index a document collection of approximately 40,000 records is described. An analysis of the results is presented which indicates the difficulties inherent in applying the results to an operating system. (11 references) (Author)

The investigation is part of a continuing project to find better means for studying and evaluating document representations (e.g., abstracts, indexes). The present study focused on understanding the ways individuals interpret index terms, with the goal of using the findings in improving indexing systems. Indexing systems use all-or-none bases for…

Discussion of the failure of individual keywords to identify conceptual content of documents in retrieval systems highlights Metric Similarity Modeling, a method for creating vector space representation of documents based on modeling target interdocument similarity values. Semantic relatedness, latent semantic indexing, an indexing and retrieval…

Briefly reviews early work in documentation and text processing, and predictions that were made about the creative role of computers in information retrieval. An attempt is made to explain why these predictions were not fulfilled and conclusions are drawn regarding the limits of computer power in text retrieval applications. (Author/CLB)

An access method for bibliographic records that combines features of the search key approach and the inverted file approach. Permits extension of search key technique to large files. (Author/LS)

THE BACKGROUND, OPERATIONAL, AND PROCEDURAL EVENTS LEADING TO AND INCLUDED IN THE BUILDING OF THE "THESAURUS OF ENGINEERING AND SCIENTIFIC TERMS" ARE DISCUSSED. THE WORK WAS PERFORMED BY THE OFFICE OF NAVAL RESEARCH, AT THE REQUEST OF THE DIRECTOR, DEFENSE RESEARCH AND ENGINEERING, UNDER A SPECIALLY ESTABLISHED TASK NAMED PROJECT LEX.…

This thesis describes work done as part of the Video Console Indexing Project (VICI), a program to improve the quality and reduce the time and work involved in indexing documents. The objective of the work described was to design a video terminal system which could be connected to a main computer to provide rapid natural communication between the…

This bibliography includes studies of defense mechanisms, in general, and studies of multiple mechanisms. Defense mechanisms, briefly and simply defined, are the unconscious ego defendants against unpleasure, threat, or anxiety. Sigmund Freud deserves the clinical credit for studying many mechanisms and introducing them in professional literature.…

Sigmund Freund worked with the mechanisms of displacement, substitution, and sublimation. These mechanisms have many similarities and have been studied diagnostically and therapeutically. Displacement and substitution seem to fit in well with phobias, hysterias, somatiyations, prejudices, and scapegoating. Phobias, prejudices, and scapegoating…
