The purpose of this paper is to derive optimal rules for sequential mastery tests. In a sequential mastery test, the decision is to classify a subject as a master or a nonmaster, or to continue sampling and administering another random test item. The framework of minimax sequential decision theory (minimum information approach) is used; that is,…

The process of psychiatric diagnosis has recently undergone major revision with the appearance of the Diagnostic and Statistical Manual III (DSM III). The article examines the new system of multiaxial diagnoses in relation to existing special education categories. (Author)

Discusses the need for tools that analyze Earth changes in time ranges, and describes a data structure for creating and managing archives of thematic maps derived by classifying remotely sensed images by soft techniques (soft maps). Considers time-based models and provides an example of the new data structure. (Author/LRW)

Discusses hierarchical text classification for electronic information retrieval and the measures used to evaluate performance. Proposes new performance measures that consist of category similarity measures and distance-based measures that consider the contributions of misclassified documents, and explains a blocking measure that identifies…

Presents a background on theory in knowledge organization, which has moved from an epistemic stance of pragmatism and rationalism (based on observation of the construction of retrieval tools), to empiricism (based on the results of empirical research). Discusses historicism, external validity, classification, user-interface design, and…

Describes the methods, processes, and procedures used to develop the Classification of Instructional Programs 2000 (CIP:2000), the National Center for Education Statistics taxonomy of instructional programs, and provides information on the CIP's structure, contents, and organization. (SLD)

This article explains features of the 1992 American Association on Mental Retardation's definition and classification of mental retardation and then discusses six major implications of the system, such as the purpose of diagnosis, basis of classification, reliance on clinical judgment, provision of education and habilitation services, focus on…

Describes a Statistical Analysis System (SAS) MACRO for computing various indices of interrater agreement, including a new generalizability coefficient, for categorical data in a single-facet, crossed design. (Author/SLD)

Surveys ongoing metadata projects to identify the types of metadata that exist and how they are used; compares and analyzes selected metadata elements to illustrate how they are related to MARC 21 metadata format elements; and discusses metadata standards, Dublin Core, diversity in classification, and the role of the Library of Congress.…

Discusses the concept of document genres and its applicability to communication on the Web; examines 1000 randomly selected Web pages and categorizes the type of genre represented; considers whether genres are being adapted or created on the Web; offers suggestions for Web site designers; and lists characteristics of some identified genres. (LRW)

Focuses on the need for a systematic redefinition of the archival methods and tools required for building electronic recordkeeping systems. Developed for archival education in Italy, it examines the historical evolution of records creation (classification and the registry system) and the evaluation of their effectiveness in the newly developed and…

This poem discusses Melvil Dewey's system for organizing information, focusing on information related to American Indians. Suggests instead of grouping all materials on Indians in one place they could be distributed throughout the Dewey system. (LRW)

Presents a conceptual framework for putting program theory into operation. The framework incorporates variables that reflect theoretical concepts and implementation issues addressed in program evaluation. It organizes variables into input, process, and output categories. Discusses implications for program evaluation. (SLD)

Presents latent-class models that fall within the purview of the general model presented by C. Clogg and L. Goodman (1984, 1985) and S. Walter and L. Irwig (1988). These models allow the investigator to determine whether the criterion measure and the diagnostic or screening procedure should be considered error free. (SLD)
