Research Projects

Title: A Big Data Analytics Approach for Identifying Reuse-Proneness of Object-Oriented Classes in Source Code Management Systems

Developing classes with high reuse-proneness is difficult and expensive, and hence, often neglected by software developers. The issue with class reuse is that developers would need to spend a significant amount of effort to: i) identify the candidate classes to be reused, ii) isolate the reusable classes and all their dependencies from other classes, and iii) make sure that the candidate classes can be reused in a new operating environment. In order to better manage software development, developers have started to adopt Source Code Management Systems (SCMS) as a medium of collaboration to track, audit, and report software bugs and defects. Vast information stored in SCMSs made it easier for developers to assess the reuse-proneness of classes.Eventually, the assessment of reuse-proneness will give developers who want to reuse a class a better idea of how easy the reuse can be accomplished. In this research, we focus on using a big data mining approach to assess the reuse-proneness of classes in a software system. Data from diverse sources such as change log, change history, bug reports, developers’ activities, and developers’ contributions of a software project are collected and analysed to assess and identify potential reusable classes. The proposed approach is supported by a lightweight parser that reads through and analyse the software artifacts stored in the SCMS. Weighted complex networks are created to illustrate the interactions of all software components from a graph theory point-of-view. Subsequently, software metrics and graph theory metrics correlated to reuse-proneness are applied to reveal reuse-prone software components. Finally, an automated tool will be developed to recommend a list of highly reusable classes to software developers based on the findings. The proposed approach can aid in provide a better understanding of how easy to reuse a particular class, and also assess the quality of software systems.

Title: A Genetic Algorithm-based Software Clustering Approach to Aid in Remodularization of Software Systems

This research focuses on software clustering as one of the solutions to aid in software remodularization. Software clustering can be performed either in supervised or unsupervised approach to pick from a collection of software entities, then form multiple groups of entities such that entities within the same group are similar to each other, while dissimilar from entities in other groups. The typical processes of clustering are as follows. First, common features are chosen to determine similarity between entities. Second, a similarity measure is chosen to determine the similarity strength between two entities. Third, a clustering algorithm is chosen to group similar entities together. Finally, a form of validation is required to measure the quality of clustering results. In this research project, we will investigate new approaches that facilitate in the first and second processes, which is to effectively identify common feature between software entities and propose a novel way to quantify the similarity between multiple entities. The specific tasks are: 1. Study the state-of-the-art approaches in software clustering to aid in remodularization of software systems. 2. Perform experimental evaluation of the proposed approach on real datasets (source code retrieved from open-source software projects).
