Mining Software Components from Object-Oriented APIs

Object-oriented Application Programing Interfaces (APIs) support software reuse by providing pre-implemented functionalities. Due to the huge number of included classes, reusing and understanding large APIs is a complex task. Otherwise, software components are admitted to be more reusable and understandable entities than object-oriented ones. Thus, in this paper, we propose an approach for reengineering object-oriented APIs into component-based ones. We mine components as a group of classes based on the frequency they are used together and their ability to form a quality-centric component. To validate our approach, we experimented on 100 Java applications that used Android APIs.

Recovering Architectural Variability of a Family of Product Variants

A Software Product Line (SPL) aims at applying a pre-planned systematic reuse of large-grained software artifacts to increase the software productivity and reduce the development cost. The idea of SPL is to analyze the business domain of a family of products to identify the common and the variable parts between the products. However, it is common for companies to develop, in an ad-hoc manner (e.g. clone and own), a set of products that share common functionalities and differ in terms of others. Thus, many recent research contributions are proposed to re-engineer existing product variants to a SPL. Nevertheless, these contributions are mostly focused on managing the variability at the requirement level. Very few contributions address the variability at the architectural level despite its major importance. Starting from this observation, we propose, in this paper, an approach to reverse engineer the architecture of a set of product variants. Our goal is to identify the variability and dependencies among architectural-element variants at the architectural level. Our work relies on Formal Concept Analysis (FCA) to analyze the variability. To validate the proposed approach, we experimented on two families of open-source product variants; Mobile Media and Health Watcher. The results show that our approach is able to identify the architectural variability and the dependencies.

Modeling and Analyzing Release Trajectory based on the Process of Issue Tracking

Software release development process, that we refer to as "release trajectory", involves development activities that are usually sorted in different categories, such as incorporating new features, improving software, or fixing bugs, and associated to "issues". Release trajectory management is a difficult and crucial task. Managers must be aware of every aspect of the development process for managing the software-related issues. Issue Tracking Systems (ITS) play a central role in supporting the management of release trajectory. These systems, which support reporting and tracking issues of different kinds (such as "bug", "feature", "improvement", etc.), record rich data about the software development process. Yet, recorded historical data in ITS are still not well-modeled for supporting practical needs of release trajectory management. In this paper, we describe a sequence analysis approach for modeling and analyzing releases' trajectories, using the tracking process of reported issues. Release trajectory analysis is based on the categories of tracked issues and their temporal changing, and aims to address important questions regarding the co-habitation of unresolved issues, the transitions between different statuses in release trajectory, the recurrent patterns of release trajectories, and the properties of a release trajectory.
