SEPLN 2026 Conference website: https://sepln2026.org
Introduction
The journal Procesamiento del Lenguaje Natural aims to provide an international forum for the dissemination of high-quality scientific and technical contributions in the field of Natural Language Processing (NLP). It welcomes original, unpublished work that has not been submitted simultaneously to other journals or conference proceedings.
The journal promotes the advancement of research in NLP, fosters the exchange of innovative ideas, supports the identification of emerging research directions, and showcases real-world applications and technological developments in this rapidly evolving discipline. Each year, the Spanish Society for Natural Language Processing (SEPLN) publishes two issues of the journal, including original research articles, project descriptions, book reviews, and summaries of doctoral theses.
The scientific quality of the journal is supported by its indexing in major international databases, including the 2024 JCR index (JIF: 1.3, JCI: 0.48, Q2-Linguistics – Q4-Computer Sciences, Artificial Intelligence ESCI), the SCImago Journal Ranking (2024 SJR: 0.570, Q2-Computer Science Applications, Q1-Linguistics and Language), the Scopus Index (2024 CiteScore: 7.3), and the SNIP index with 1.61 points.

Regular papers with original contributions will be accepted for publication in the Journal of Procesamiento del Lenguaje Natural.
Research projects & system demonstration papers will be published in the CEUR proceedings
Information for Authors
The proposals of regular papers with original contributions can be written in Spanish or English and should be at most 10 A4-size pages of content, plus unlimited pages for references.
The papers must include the following sections:
- The title of the communication (in English and Spanish). - An abstract in English and Spanish (maximum 150 words). - A list of keywords or related topics (in English and Spanish). - The documents must not include headers or footers.
As reviewing will be doubled-blind, the paper should not include the authors’ names and affiliation. Furthermore, self-references that reveal the author’s identity should be avoided. The articles should only include the title, the abstract, the keywords and the proposal.

SEPLN Workshops Proceedings. The high quality papers will be published in the issue 77 of the journal Procesamiento del Lenguaje Natural. Those papers that the reviewers assess as quality papers, but without the consideration of high quality papers will be published in the CEUR proceedings. These works will be presented as posters in the 42nd SEPLN Conference.
Research project & System Demonstration Session. This session will be focused on ongoing NLP research projects and system demonstration papers.
The summaries of ongoing research projects must include the following information:
- Project title. - Author name, affiliation and contact information. The review of this kind of paper is not blind review. - Funding institutions. - Research Groups participating in the project. - Language: English. We will not accept research project summaries in Spanish or other languages. - An abstract of a maximum of 150 words and a list of keywords. - Minimum length: 5 A4-size pages. - Maximum length: 6 A4-size pages (including references).
The System demonstration papers must be related to NLP applications, and they must describe the technical details and the NLP components used or developed. The paper must be written in English, the minimum length of the paper must be 5 A4-size pages and the maximum length is 6 A4-size pages of content with the references included.
The research project summaries and the system demonstration papers will be published in the SEPLN Workshop Proceedings. Accordingly, the paper format must be in accordance with the CEUR template. We have adapted the CEUR Latex Template to SEPLN 2026 and you can download it here (LaTeX, Word).
Note on camera ready The final version of the paper (camera ready) should be submitted together with a cover letter explaining how the suggestions of the reviewers were implemented in the final version. This cover letter will be considered in order to accept or finally reject the selected paper.
Preprint policy The Journal allows the publication of preprints (non-refereed paper posted online, such as ArXiv) anytime, but during the review period the preprint must indicate that the paper it is “under review” in the Journal Procesamiento del Lenguaje Natural. Likewise, if the paper is accepted, the preprint must be updated with the DOI, name of the Journal and the bibliographic information of the paper.
