NEW: Submission deadline extended: May 20, 2018 – 23:59 (GMT-11)

The International Conference on Computational Processing of Portuguese (PROPOR) is the main scientific conference in the area of language and speech technologies for Portuguese that is concerned with its basic and applied research issues related to this language. PROPOR 2018 will be held on September 24-26, 2018 in the city of Canela, Brazil. Canela is located in the Serra Gaúcha of Rio Grande do Sul, Brazil. Both Canela and city neighboring Gramado are important tourist resorts and they both draw many visitors each year. The conference will have 3 days of paper presentations, special tracks and workshops.

Important dates

  • Demo submission (EXTENDED): May 20, 2018 – 23:59 (GMT-11)
  • Notification of acceptance: June 15, 2018
  • Camera-ready version: July 1, 2018
  • Conference: September 24-26, 2018

Call for Demonstrations

The PROPOR 2018 Demonstration Program Committee invites submissions for Demonstrations. Following the spirit of the Demo Sessions 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 adopting a more informal setting. Products, systems or tools are examples of acceptable demos. Both early-research prototypes and mature systems may be considered.

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

  • Human speech production, perception and communication
    • Human speech production
    • Human speech and sound perception
    • Physiology and pathology of spoken language
    • Paralinguistic and nonlinguistic cues (e.g. emotion and expression)
  • Linguistic Description and Theories
    • Phonology and phonetics, prosody (e.g., production, perception, modeling)
    • Syntactic, semantic and anaphoric phenomena
  • Natural Language Processing Tasks
    • Parsing, tagging, chunking and segmentation
    • Annotation, evaluation, semantic role labeling
    • Grammar induction, subcategorization acquisition
    • Sentiment analysis and opinion mining
  • Natural Language Processing Application
    • Word sense disambiguation
    • Dialect identification
    • Machine translation
    • Information retrieval
    • Plagiarism detection
    • Question answering
  • Speech Technologies
    • Spoken language generation and synthesis
    • Speech and speaker recognition
    • Spoken language understanding
  • Speech Applications
    • Spoken language interfaces and dialogue systems
    • Systems for information retrieval and information extraction
    • Systems for speech-speech translation
    • Applications for aged and handicapped people
    • Applications for learning and education
  • Resources, standardization and evaluation
    • Spoken language resources, annotation and tools
    • Spoken language evaluation and standardization
    • NLP resources, annotation and tools
    • NLP evaluation and standardization
  • Language and Speech processing in academic disciplines
    • Speech and Hearing sciences, Health, Biology
    • Linguistics, Psychology, Education

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 (3) 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 of Portuguese language in the proposed system.

Documents should be written in English, following the LNAI format (LaTeX style, MS Word style), and submitted by e-mail to

Accepted demos and the accompanying paper will be published on the BDBComp.

Presentation Format

Accepted demos will be presented on table tops at a designated demo session with an optional accompanying poster. Developers should make sure they can run their demos properly. it is the developer’s duty to provide the necessary technical conditions (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.
