A process to build a measurement framework for knowledge-based system development

In this paper, we stress the importance of considering evaluation from an overall viewpoint in order to produce higher quality Knowledge-Based Systems (KBS), that is, measuring attributes of products generated throughout the entire system life cycle rather than the final system alone. A framework for measuring typical products obtained during the development phases is proposed here. This measurement framework includes the definition of the products and the definition of attributes that characterize these products. The attributes are ordered as a multilevel hierarchy. The aim of the measurement framework proposed is to facilitate the application of measurement plans to KBSs, using associated metrics. When building this environment, we sought to unify other work in the field of KBS evaluation.
