Semantic Similarity Based on Corpus Statistics and Lexical Taxonomy
Jay J. Jiang,David W. Conrath +1 more
TL;DR: This paper presents a new approach for measuring semantic similarity/distance between words and concepts that combines a lexical taxonomy structure with corpus statistical information so that the semantic distance between nodes in the semantic space constructed by the taxonomy can be better quantified with the computational evidence derived from a distributional analysis of corpus data.

A Socio-Technical Framework for Quality Assessment of Computer Information Systems
TL;DR: A socio‐technical approach to determining the quality of a computer information system is recommended and two postulates have been proposed and tested by field survey of expert systems in the insurance industry in North America.

A socio‐technical framework for quality assessment of computer information systems
TL;DR: The emergence of total quality management and the ISO 9000 suite of standards has allowed a re-think of how (and why) the post-implementation evaluation of computer systems is to be carried out Traditional performance measurement, modeling and analysis techniques have been tempered with a more holistic ideology as mentioned in this paper.

Toward a diagnostic instrument for assessing the quality of expert systems
David W. Conrath,Ravi S. Sharma +1 more
TL;DR: The solution is a diagnostic instrument that assesses the relative strengths and weaknesses of an operational expert system that is based on underlying concepts form socio-technical theory and empirically subjected to a rigorous validation methodology.
