Efficient recovery of algebraic specifications for stateful components

Specification recovery is a necessary step of many reverse engineering and reuse efforts. This paper deals with recovering the semantic part of a component's interface. It focuses on stateful components that provide data abstractions. Recovery is achieved by following a black-box strategy, i.e. by observing the component's dynamic behavior. Among the published approaches, Heureka recovers algebraic specifications from Java classes. Another approach (Adabu) recovers behavioral models. The work we describe here adapts the latter, which provides an approximate semantic description for the class, to significantly optimize the former. The resulting approach, called Adiheu, is described in the paper with a preliminary assessment.
