Natural language processing (NLP) plays an essential role in several areas of software engineering (SE), and requirements engineering (RE) is no exception. Requirements are generally authored and communicated in textual form and different levels of formality, from structured (e.g., user stories) to unstructured natural language. In the last few years, the advent of massive and heterogeneous sources, such as tweets and app reviews, has attracted even more interest from the RE community, and the recent developments in large language models (LLMs) and generative AI have opened new opportunities for RE. LLMs will likely be the enabling technology for solving long-standing RE problems, such as traceability, classification, and compliance.

The main goal of NLP4RE is to represent a community- building venue for researchers who apply NLP technologies to solve RE problems and automatically support RE activities.

The NLP4RE Workshop is co-located with REFSQ'25. Check out the REFSQ'25 Conference here.

The workshop welcomes contributions regarding both theory and application of NLP technologies in RE. We also encourage contributions that highlight challenges faced by industrial practitioners when dealing with requirements expressed in NL, and the experiences of academics in technology transfer.

We are interested in Tool Papers (see the Call for Papers), in which the authors provide a brief description of an NLP tool for RE, and a plan for a tool demo at the workshop.

We are also interested in Report Papers (see the Call for Papers), in which the authors provide an overview on the current and past research of their teams. These contributions do not require novelty with respect to previous work, because the main goal of the workshop is to foster discussion and networking.

Moreover, this year we encourage submissions discussing the following topics:

• Large Language Models (LLMs) and RE

  How traditional and recent RE tasks (e.g., issue classification, prompt engineering) can be solved with the new developments in LLMs and chat-based NLP solutions (e.g., ChatGPT, BARD, Bing Chat), and how RE can help the development of LLMs.

• Traditional vs. advanced NLP

  Comparative analysis of automated solutions that solve RE tasks using traditional versus advanced NLP solutions (e.g., LLMs).

• Education

  The integration of NLP4RE in the general RE educational programs, and how LLMs could change how we teach programming and other SE tasks.

• Ethical challenges in NLP4RE research

  Studies on the impact of NLP4RE tools and techniques on humans and related ethical challenges.

• Replicability of NLP4RE

  Studies that replicate NLP4RE tools as well as studies that survey the replicability of the NLP4RE research.

• Evaluation in NLP4RE

  Studies on the evaluation of NLP4RE tools, including but not limited to analysis of the automation against human performance and collaborative modes combining human performance with automated solutions.

Specific topics of interest include but are not limited to:

Long Papers

10 pages (plus 2 pages for references). Submissions in this category may present novel technical solutions, evaluations of existing methods, or empirical studies. Empirical evaluations may include experiments, case studies, surveys, user studies, or other qualitative and quantitative analyses. Papers should focus on the application of NLP technologies to problems relevant to requirements engineering. Accepted long papers will be included in the proceedings of the workshop.

Short Papers

5 pages (plus 1 page for references). Submissions in this category can include vision papers, reports on ongoing projects or research group activities, tool papers, as well as new ideas or early-stage research. Short papers should aim to stimulate discussion by presenting emerging concepts or offering insights into innovative approaches related to the application of NLP technologies to requirements Engineering. Accepted short papers will be included in the proceedings of the workshop.

Conference-first Papers

1 page (including references), in which the authors present a paper previously presented at RE, REFSQ or ICSE. The contribution should briefly summarize the content of the original paper. These contributions are oriented to foster dissemination, and will not appear in the proceedings.

Format and requirements

Submissions should be written in English and submitted in PDF format (page size A4, single column) formatted according to the CEUR Proceedings Style:

• Overleaf CEURArt Template (please use 1-column style): https://www.overleaf.com/read/gwhxnqcghhdt
• CEUR Template Download: http://ceur-ws.org/Vol-XXX/CEURART.zip

It is required for at least one author of each accepted submission to register, attend the workshop and present their research to the workshop participants.

All papers will undergo a traditional single-blind peer-review process (3 reviews per paper) to check scientific soundness, adequacy to the workshop topics, and compliance with the required template. We plan to publish the accepted papers in the CEUR Proceedings, with ISBN number.
