Call for demonstrations

The PROPOR 2024 demonstration program committee invites submissions for demonstrations. Following the spirit of previous PROPOR editions, the demonstration track aims at bringing together academia and industry, creating a forum where more than written or spoken descriptions of research are available. Thus, demos should allow attendees to try and test them during their presentation in a dedicated session that will provide a more informal and interactive setting. Products, systems, or tools are examples of acceptable demos. Both early-research prototypes and mature systems may also be considered.

Important dates:

  • Demos Submission: January 10 2024
  • Notification of acceptance or rejection: February 21 2024
  • Camera-ready demo paper: February 28 2024
  • Conference: March 14 and 15 2024


The areas of interest include all topics related to theoretical and applied issues of written and spoken Portuguese and Galician, such as, but not limited to, the same topics as for the conference paper submission:

  • Natural language processing tasks (e.g. parsing, word sense disambiguation, coreference resolution)
  • Natural language processing applications (e.g. question answering, subtitling, summarization, sentiment analysis)
  • Natural language generation
  • Information extraction and information retrieval
  • Speech technologies (e.g. spoken language generation, speech and speaker recognition, spoken language understanding)
  • Speech applications (e.g. spoken language interfaces, dialogue systems, speech-to-speech translation)
  • Resources, standardization and evaluation (e.g. corpora, ontologies, lexicons, grammars)
  • NLP-oriented linguistic description or theoretical analysis
  • Distributional semantics and language modeling
  • Portuguese language varieties and dialect processing (including the language varieties of Angola, Brazil, Cape Verde, East Timor, Galicia, Guinea-Bissau, Macau, Mozambique, Portugal, São Tomé, and Principe)
  • Multilingual studies, methods, applications, and resources including Portuguese/Galician

The systems may be of the following kinds:

  • Natural Language Processing systems or system components
  • Application systems using language technology components
  • Software tools for computational linguistics research
  • Software for demonstration or evaluation
  • Development tools


Submissions should consist of a non-anonymous brief description document of up to three pages of content, including references. Developers must outline the main characteristics of their system/product/tool, provide sufficient details to allow its evaluation, and give information on how they plan to demonstrate it. Developers are encouraged to focus their description on the relevance of the computational processing component of Portuguese or Galician in the proposed system.

Submissions should be written in English. At submission time, only PDF format is accepted. For the final versions, authors of accepted papers will be given one extra content page to take the reviews into account. Authors of accepted papers will be requested to send the source files for the production of the proceedings.

Submissions must be sent via EasyChair ( — please select the track: PROPOR2024 Demo Paper.

All submitted papers must conform to the official ACL style guidelines. ACL provides style files for LaTeX and Microsoft Word that meet these requirements. They can be found at:


Accepted demo papers are expected to be published by ACL as a volume in ACL Anthology ( as part of the PROPOR 2024 proceedings. They will be available online. To ensure publication, at least one author of each accepted paper must complete an adequate registration for PROPOR 2024 by the early registration deadline.

Presentation format:

Accepted demos will be presented at a designated demo session with an optional accompanying poster. Developers should make sure they could run their demos properly. Thus, it is the authors’ responsibility to provide the necessary technical conditions (i.e. equipment) for the demo at the conference. Note that the local organizers will not provide any hardware or software. Free high-speed Internet access will be available.

There will be a best demo award for the best-presented project.

Further details on the date, time, and instructions of the demonstration session(s) will be determined and provided at a later date.
