Software fault localization, the act of identifying the locations of faults in a program, is widely
recognized to be one of the most tedious, time consuming, and expensive-yet equally critical …

Due to the increasing scale and complexity of software products, software maintenance
especially on bug resolution has become a challenging task. Generally in large-scale …

The application of information retrieval techniques to search tasks in software engineering is
made difficult by the lexical gap between search queries, usually expressed in natural …

For a large and evolving software system, the project team could receive a large number of
bug reports. Locating the source code files that need to be changed in order to fix the bugs is …

Locating bugs is important, difficult, and expensive, particularly for large-scale systems. To
address this, natural language information retrieval techniques are increasingly being used …

Context Topic modeling finds human-readable structures in unstructured textual data. A
widely used topic modeling technique is Latent Dirichlet allocation. When running on …

When a new bug report is received, developers usually need to reproduce the bug and
perform code reviews to find the cause, a process that can be tedious and time consuming …

The automated task of locating the potential buggy files in a software project given a bug
report is called bug localization. Bug localization helps developers focus on crucial files …

Debugging is a costly process that consumes much of developer time and energy. To help
reduce debugging effort, many studies have proposed various fault localization approaches …

Various information retrieval (IR) based techniques have been proposed recently to locate
bugs automatically at the file level. However, their usefulness is often compromised by the …
