Background: According to Salo (2010), the metadata entered into repositories are "disorganized" and metadata schemes underlying repositories are "arcane". This creates a challenging repository environment in regards to personal information management (PIM) and knowledge organization systems (KOSs). This dissertation research is…

The identification of valid terms in any domain is fundamental to its computerization. For this reason, in this paper we present a method for obtaining automated morphosyntactic patterns, which will help researchers to obtain valid terms from the proposed patterns, in order to build quality ontologies for the translation from one language to…

Surveillance video recording is becoming ubiquitous in daily life for public areas such as supermarkets, banks, and airports. The rate at which surveillance video is being generated has accelerated demand for machine understanding to enable better content-based search capabilities. Analyzing human activity is one of the key tasks to understand and…

A low-cost automatic classification method is reported that uses computer time in proportion to NlogN, where N is the number of information items and the base is a parameter, some barriers besides cost are treated briefly in the opening section, including types of intellectual resistance to the idea of doing classification by content-word…

This report describes a quantitative study of subject-indexing as it is being performed by catalogers who are developing an augmented catalog as part of Project Intrex. Learning curves for the average time taken to index technical documents on a per-page basis were derived for a group of indexers. The average indexing times per page were also…

A series of experiments was performed to investigate the effectiveness and utility of automatically classifying documents through the use of multiple discriminant functions. Classification is accomplished by computing the distance from the mean vector of each category to the vector of observed frequencies of a document and assigning the document…

The report very briefly summarizes the research performed during the contract period March 1, 1964, to February 28, 1971. The emphasis of the research was on the discovery and development of techniques for automatically indexing and classifying documents. The research was limited to statistical techniques rather than semantic or syntactic. A…

Presents a method for identifying indexing terms from word stems, using discriminant analysis to distinguish terms which refer to topics from terms which do not refer to topics. A test of the method on the Harris Survey Question database is discussed. Included are 11 data tables and a reference list. (Author/JL)

A collection of twenty-three lexical resources in information science, published in both the United States and Europe between 1960 and 1967, was analyzed with the purpose of tabulating the occurrence of different terms in them. This analysis, accomplished by means of a matrix generated on the IBM System 360 Model 40 computer, quantified the…

Examines the literature on the myth of "hard science-soft science" as a means of defining scientific specialties and classifying science literature, and discusses some shortcomings of scholarship in library and information science. Use of Toulmin's categorization of sciences to organize the literature and provide access for scientists is…

The major advantage of sequential classification, a technique for automatically classifying documents into previously selected categories, is that the entire document need not be processed before it is classified. This method assumes the availability of a priori categories, a selection of keywords representative of these categories, and the a…

The feasibility of using a distance measure, called the Bayesian distance, for automatic sequential document classification was studied. Results indicate that, by observing the variation of this distance measure as keywords are extracted sequentially from a document, the occurrence of noisy keywords may be detected. This property of the distance…

The objectives of this research were to investigage (1) the feasibility of an index simulator, and (2) the use of a sequential analysis model for the automatic classification of documents. Index simulation was studied in general for various types of indexes, and in depth for the simulation of an inverted coordinate index to a document collection…
