Organizations with large integrated computer-based systems are often faced with the challenge of evolving their mission-critical systems in a manner that maximizes reuse opportunities, minimizes redundancies, and addresses business goals. To support these goals system developers must be provided with tools that allow them effectively assess the impact of change across the systems (impact analys...

This paper describes the classification mechanism of ROSA, a software reuse system based on the processing of the natural language descriptions of software artifacts. The system supports the automatic indexing of components by acquiring lexical, syntactic and semantic information from software descriptions. Major goals of the approach are cost-effectiveness and retrieval precision. Some results...

Object-oriented frameworks promise higher productivity and shorter time-to-market for the development of objectoriented applications. These goals are achieved through design and code reuse. While many projects show that these promises can be met, failed projects also show that they are not always easy to reach. This dissertation addresses three pertinent technical problems of designing, learnin...

Researchers have been interested in exploring the regularities and modularity of the problem space in genetic programming (GP) with the aim of decomposing the original problem into several smaller subproblems. The main motivation is to allow GP to deal with more complex problems. Most previous works on modularity in GP emphasise the structure of modules used to encapsulate code and/or promote c...

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 t...

Much published research on data integration considers only a “one shot” effort to produce an integrated schema or a multidatabase query. This paper examines a more complex environment. Our clients CBST~ out multiple integration efforts, producing multiple kinds of integrated systems that involve overlapping subsets of their component databases. Metadata is costly to collect and maintain, so one...

Over the past several years, a number of techniques have been developed to address various issues involving software reuse, such as component classification, retrieval, and integration. However, it is not adequate to only have reuse techniques that address reuse issues separately. Instead, a seamless integration of these reuse techniques is critical to achieve effective reuse. In this paper, we...
