Similarity for analogical software reuse: A conceptual modelling approach

Abstract. We present our approach to defining similarity between software artifacts and discuss its potential exploitation in software reuse by analogy. We first establish properties of similarity which support its role in retrieving and mapping software descriptions. Then we develop a systematic basis for comparison within a fairly general conceptual modelling framework, whereby comparable elements of the descriptions of software objects and corresponding similarity criteria are identified. Finally, a general form of distance metrics for the computation of similarity measures is defined. 1. Introduction: The Analogical Based Approac
