Describes method of automatic document classification in which documents classed as QA by Library of Congress classification system were clustered at six thresholds by keyword using single link technique. Automatically generated clusters were compared to Library of Congress subclasses, and partial classified hierarchy was formed. Twelve references…

This paper briefly summarizes the characteristics of 14 of the currently most popular computer pragrams for cluster analysis. Also provided is a subjective ranking of the programs in terms of their versatility and usability. (Author)

CUTOFF is a program to identify the most efficient classification prediction cutting score. It ranks the scores of a criterion and a comparison group and organizes them into cumulative frequency tables allowing for immediate display of an index of correct identifications associated with each score.

The computational model of question answering proposed by a computer program, QUALM, is a theory of conceptual information processing based on models of human memory organization. It has been developed from the perspective of natural language processing in conjunction with story understanding systems. The processes in QUALM are divided into four…

In planning the development of the system for computer assisted assembly of tests, it was agreed at the outset that one of the basic requirements for the successful initiation of any such system would be the development of a detailed item content classification system. The design of the system for classifying item content is a key element in…

The issues in the interpretation of discriminant analyses presented are restricted to the typical uses of discriminant analysis by behavioral science researchers. Because behavioral researchers use computer programs packages, the issues discussed deal with information obtainable from the package discriminant analysis programs. The following issues…

Two basic requirements for the successful initiation of a program for test assembly are the development of detailed item content classification systems and the delineation of the professional judgements made in building a test from a pool of items to detailed content, ability, and statistical specifications in terms precise enough to be translated…

The authors state that multiple regression is a powerful method of statistical analysis, provides a strength of relationship index, and should replace analysis of variance (ANOVA) in educational research. They also discuss the coding of categorical variables and available computer programs for multiple regression. (Author/MH)

This paper describes a locally-developed multi-purpose system that stores data about any number of special collections within the libraries and prints that data in a number of formats on demand or as scheduled reports. The system operates on an IBM 360/67 dual processer with data entry via a teleprocessing system. The key to the file is the call…

This paper provides a scientific basis for the formulation and expression of performance standards and specifications and for explicit attention to performance in procedural and prescriptive standards and specifications. The provisions of "Interim Performance Criteria for Solar Heating and Combined Heating/Cooling Systems and Dwellings," a…

A computer simulation of Bayes' Theorem was conducted in order to determine the probability that an examinee was a master conditional upon his test score. The inputs were: number of mastery states assumed, test length, prior expectation of masters in the examinee population, and conditional probability of a master getting a randomly selected test…

A computer simulation model for allocating facilities and physical space is presented as a means of optimally allocating available educational resources. The model allows the decisionmaker to change specific program allocations, system parameters, and other controllable variables in order to determine the effects, both cost and utility, of these…
