Call for papers


The Spanish Society for Natural Language Processing (SEPLN) is pleased to invite you to participate in the 37th edition of the SEPLN Conference.

The huge amount of information available in digital format and in different languages calls for systems to enable us to access this vast library in an increasingly more structured way. In this same area, there is a renewed interest in improving the information accessibility and information exploitation in multilingual environments. Most of the formal foundations for dealing appropriately with these necessities have been, and are still being, established in the area of Natural Language Processing 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 aim of the SEPLN Conference is to provide, both to the scientific community and to the industry, a forum where to present and share the latest research and developments in the field of Natural Language Processing (NLP). The SEPLN Conference also gives the possibility to present real NLP applications, as well as different R+D projects.

Additionally, as in previous editions, there is the intention of identifying future guidelines or paths for basic research and foreseen software applications, in order to compare them against the market needs. Finally, the conference intends to be an appropriate forum in helping new professionals to become active members in this field.

Guide for authors

All contributions must be submitted electronically using the Myreview system available at http://myreview.sepln.org/myreview-sepln67/

Authors are encouraged to send theoretical or application-oriented proposals related to NLP. The proposals must include the following sections and features:

  • The title of the communication;
  • An abstract in English and Spanish (maximum 150 words) and a list of keywords;
  • The paper can be written in either Spanish or English. Its overall maximum length will be 10 pages, excluding acknowledgments and references;
  • One additional page will be allowed if necessary to respond to reviewers comments. In that case, new content needs to be justified in the response to reviewers.
  • The documents must not include headers or footers;
  •  Papers should NOT include the names of the authors.

Projects and Demos

Like in previous years, the organizers encourage participants to give presentations of R&D projects and demos of systems or tools related to the NLP field. The session will be poster-based. For presentations on R&D projects to be accepted, the following information must be included:

  •  Project title;
  •  Author name, affiliation, address, e-mail and phone number;
  •  Funding institutions;
  •  Research Groups participating in the project;
  •  An abstract in English and Spanish (maximum 150 words) and a list of keywords;
  •  Maximum length: 4 pages (including references).
  •  Choose 'Projects and Demos' as main topic.

    In this edition, demos and projects will be published in a CEUR accompanied proceedings volume.



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.

Manuscript submission guidelines for the SEPLN journal must be followed: http://www.sepln.org/en/journal/author-guidelines

In addition, all proposals will have to comply with the above mentioned requirements no matter they are papers, demos or projects.
