Developers discuss software architecture and concrete source code implementations on a
regular basis, be it on question-answering sites, online chats, mailing lists or face to face. In …

Abstract Syntax Trees (ASTs) are widely used beyond compilers in many tools that measure
and improve code quality, such as code analysis, bug detection, mining code metrics …

We study the possibilities to track provenance of software source code artifacts within the
largest publicly accessible corpus of publicly available source code, the Software Heritage …

Today, most developers bundle changes into commits that they submit to a shared code
repository. Tangled commits intermix distinct concerns, such as a bug fix and a new feature …

Software developers rely on various repositories and communication channels to exchange
relevant information about their ongoing tasks and the status of overall project progress. In …

Abstract Machine learning methods have been applied in software engineering to effectively
predict software defects. Researchers proposed cross-project defect prediction (CPDP) for …

We consider the problem of mining the development history—as captured by modern
version control systems—of ultra-large-scale software archives (eg, tens of millions software …

Evolving software is a highly complex and creative problem in which a number of different
strategies are used to solve the tasks at hand. These strategies and reoccurring coding …

With the advent of fast software evolution and multistage releases, temporal code analysis is
becoming useful for various purposes, such as bug cause identification, bug prediction or …

Call Graphs are a rich data source and form the foundation for advanced static analyses that
can, for example, detect security vulnerabilities or dead code. This information is invaluable …
