40th International Conference of SEPLN



Valladolid, Spain

September 24-27, 2024


The Spanish Society for Natural Language Processing (SEPLN) is pleased to invite you to participate in the 40th edition of the SEPLN Conference. The SEPLN Conference will take place on 25-27 September 2024 at Valladolid (Spain) at University of Valladolid. 


The huge amount of digital information available in different languages has created the need for systems to access this valuable resource in an increasingly structured way. Thus, there is a renewed interest in improving the ways in which we can access and leverage this information in multilingual environments. The formal and technological foundations to address these needs have and keep being proposed from the area of Natural Language Processing (NLP) and its many branches: information extraction and retrieval, language models, question answering, machine translation, automatic analysis of textual content, text summarization, text simplification, text generation, and speech recognition and synthesis.


The main objective of the SEPLN 2024 Conference is to provide both the scientific community and the industry with a forum to present and share the latest research and developments in the field of NLP. The SEPLN 2024 Congress also gives the possibility to present real NLP applications being an appropriate forum to help new professionals to become active members in this field.


In past editions, the SEPLN Conference had a special focus on the presentation of R&D projects and applications (demos). In this edition, the section of demos and R&D projects is detached, being presented in a seminar within the Spanish Congress of Informatics CEDI to be held in A Coruña on June 20, 2024. The demos and projects seminar has its own call for participation in (https://seplncedi2024.gplsi.es/)

Structure of the Conference


The SEPLN 2024 Conference will be a four-day event and will include sessions to present papers, ongoing research projects and prototype or product demos related to the topics of the conference. Likewise, the 24th of September will take place the Workshop Day, where the main workshop will be IberLEF 2024.


Paper types and author guidelines


The SEPLN 2024 Conference will accept original scientific contributions in the topics of the conference. Research project summaries and system demonstration papers should be submitted to the CEDI seminar at https://seplncedi2024.gplsi.es/


The accepted scientific contributions will be published in the Journal Procesamiento del Lenguaje Natural, whose aim is to promote the development of areas related to NLP, disseminate research carried out, identify future guidelines for basic research, and present software applications in this field. The scientific quality of the Journal is supported by the 2022 JCR index (JCI: 0.32, Q4-Linguistics - ESCI), the SCImago Journal Ranking (SJR: 0.42, Q4-Computer Science Applications, Q2-Linguistics and Language), the Scopus Index (CiteScore: 2.9, Q4-Computer Science Applications, Q2-Linguistics and Language) and  the index SNIP (Source Normalized Impact per Paper) with 0.93 points. More information at http://www.sepln.org/en/journal/quality.


The papers can be written in Spanish or English and must 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).

● The paper must be anonymized, since the Journal follows a double-blind review process.

● An abstract with a maximum  of 150 words (in English and Spanish).

● A list of keywords or related topics (in English and Spanish).

● The documents must not include headers or footers.


The information about all the details of the format of the papers and the Latex and Microsoft Word template are at: http://www.sepln.org/en/journal/author-guidelines.


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 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.


Submission Information. The papers must be submitted by March 17th, 2024. All submissions must be in PDF format and submitted electronically using the MyReview system available at: http://myreview.sepln.org/myreview-sepln73.


Submitted papers will be subjected to a blind review by at least three members of the SEPLN advisory council.
