Concept versioning: a methodology for tracking evolutionary concept drift in dynamic concept systems

Abstract

. Technical domains are affected by continuous change as a reflection of technological progress. Correspondingly, concept descriptions of terminological knowledge bases for such domains must be adjusted to these dynamics. In this paper we propose a concept versioning methodology which accounts for the evolutionary adaptation of already established concepts according to the gradual shaping of new standards. The approach is based on the provision of qualitative progress models for the given domain, measures for the prediction and evaluation of the significance of progress, and a representation and update scheme for concept version management. 1 INTRODUCTION Technical domains, such as information, hi-fi, or automobile technology, share a common feature, namely that their underlying concept systems undergo continuous change. These dynamics are exhibited either by the substantial augmentation of concept systems in terms of concept innovations (mirroring the introduction of new products, t...
