Abstract

Smalltalk-80 is an object-oriented system promoting "programming by reuse". However, the complexity of the Smalltalk class library makes it difficult for the non-expert user to find the problem-solving class. This paper describes ClassExpert, a tool that helps to retrieve classes matching the functional specification provided by the user. ClassExpert deploys an attribute-value classification scheme with taxonomies. This paper also shows how this scheme can be used to support reuse by specialization and modification.
