Natural Language Processing for Software Engineering

Description

This research area explores the application of state-of-the-art natural language processing methods to support, enhance and extend traditional software engineering and requirements engineering tasks. We focus on multiple areas within the software development lifecycle, including requirements specification, code generation and feedback analysis, among others. More recently, we are exploring how large language models can be leveraged to improve such tasks and generate new use cases.

The research aims at contributing both from a scientific and technical perspective, building open-source tools to be exploited by both researchers and practitioners.
