The ability to elicit information systems requirements is a necessary learning objective for students in a contemporary information systems curriculum, and is a skill vital to their careers. Common challenges in teaching this skill include both the lack of structure and guidance in information systems textbooks as well as the view that a student's…

Three major sets of factors are involved in the evaluation of classification systems: evaluation of the system according to purpose, according to design, and according to functional operation. Part A of this paper is concerned with the basic detail needs for evaluation of purpose. Eight different kinds of classification systems for the subject,…

A taxonomy for modeling information systems is presented. Epistemology is used as a prescriptive modeling basis and it is shown how the different models can be made scientifically operational by using a special kind of systems analysis. Results of a preliminary experiment based on one of the models are presented. (60 references) (Author/KE)

A classification and taxonomy are used to analyze responses from systems analysts in real-world situations. Systems analysts were given a questionnaire in attempt to: (1) determine whether requirements descriptor terms are created and used in real world situations so that they might classify domain processes and objects; (2) if terms are used, try…

Examines the structure and components of information storage and retrieval systems and information filtering systems. Identifies 13 components as representations of data objects (copies, excerpts, descriptions, abstractions, and identifying references) and functions that operate on them. Reduces the functional components to transformation and…

The Committee was established in September 1967 to study and make recommendations on Recommendation XXIX and XXX of the Report of the President's Commission on the Patent System. Based on interviews with Patent Office officials, patent examiners and classifiers and a review of Patent Office studies and documents, the Committee concluded that the…

The first task of the study was to develop valid, short-cut methods of indexing the narrative content of evaluation reports that would extract the differentiating information contained in evaluative comments simply, reliably, and with as good classification accuracy as the longer initial procedure. In the second task, the original inter-indexer…
