Using Machine Learning to find bugs

Full-time PhD studentship funded by Huawei

Description

Much of the time and cost in developing software is spent fixing bugs (errors) reported by users or testers. Due to staff turnover, outsourcing, and the complexity and size of software systems, developers may not be familiar with the code they have to fix, further increasing time and cost. 

Our state-of-the-art search engine (reference below) helps developers find the source of errors more quickly: given a bug report, it recommends (in ranked order, like a web search engine) which files may need to be fixed. Our approach uses heuristics rather than history. The aim of this PhD research is to use machine learning to improve the accuracy of the recommendations, by training the system on the text of past bug reports and on the comments and code of the software system being analysed.

This full-time PhD research will be carried out in collaboration with Huawei, which is funding the Empirical Data-Driven Bug Localisation in Software Development (EDBL) project, of which this PhD is a part of.
