============================== DEFINITION AND SCOPE ==============================

Ontology is a cross-disciplinary field concerned with the study of concepts and theories that support the building of shared conceptualizations for specific domains. In recent years, there has been a growing interest in the application of ontologies to solve modeling and classification problems in diverse areas such as Computer Science, Information Science, Philosophy, Artificial Intelligence, Linguistics, Knowledge Management, Semantic Web and many others.

The Seminar on Ontology Research in Brazil (ONTOBRAS) foresees an opportunity and provides a scientific environment in which researchers and professionals in the areas of Information Science and Computer Science can exchange knowledge about theories, methodologies, languages, tools and experiences related to theoretical basis, to the development and application of ontologies. In addition, Masters and PhD students whose research is focused on Ontologies will have in the Workshop on Thesis and Dissertations on Ontology (WTDO) a space specially designed to discuss their proposals with specialists, receive feedback on methodological issues and develop an important contact network within the community.

Now in its 12th edition, ONTOBRAS 2019 is part of a tradition that has been in place in Brazil since 2005, and was defined by the Brazilian Ontology Community as a unique, scientifically highly qualified forum for presentation and discussion of ontologies and cases of application annually taking placing in Brazil. WTDO is in its 3rd edition and has been consolidating as a rich space for discussion among researchers from different generations, contributing to the expansion and renewal of the ontology researchers community in Brazil.

Therefore, we provide a non-comprehensive list of areas and researchers communities from which we expect to receive submissions:
- Conceptual Modeling: conceptual methods and tools for formal representation of concepts in ontologies.
- Information Science: construction and use of taxonomies, thesauri, knowledge organization systems, information indexing and other applications.
- Logic and Reasoning: languages and systems for formal representation applied to representation and reasoning with ontologies.
- Philosophy: philosophical aspects that support ontological modeling, top ontologies, mereology, essence and identity, among others.
- Software engineering: ontology representation languages, system architectures, methodologies for developing systems based on ontologies.
- Linguistics and natural language processing: extraction of concepts, determination of meaning.
- Artificial Intelligence: integration of ontologies and other approaches of AI, such as learning, agents, knowledge based systems, among others.
- Ontology applications: semantic web, databases, business modeling, information retrieval, specific domains (such as life sciences, earth sciences, e-science, e-business, e-government, culture, education, engineering), and so on.

Researchers and practitioners are invited to submit theoretical, technical and practical research contributions that directly or indirectly address the issues above or related ones. We welcome submissions ranging from philosophical and theoretical foundations to new technologies and innovative applications.

ONTOBRAS this year will feature the following keynote speakers:

• Nicola Guarino (LOA, Italy)
• Mathias Brochhausen (University of Arkansas for Medical Sciences, USA) e

============================== TRACKS ==============================

The 12th edition of ONTOBRAS has two tracks:

- MAIN TRACK: focused on articles with consolidated research contributions in ontologies.
- WTDO: focused on short articles describing research proposals on ontologies, at master or doctoral level, whose theses and dissertations have not been completed on the date of the event.

============================== AWARDS ==============================

There will be awards for the 2 best papers presented in WTDO (1 at master level and 1 at doctoral level).

============================== SUBMISSION GUIDELINES (Main Track and WTDO) ==============================


Submissions (maximum of 12 pages) must be written in PORTUGUESE, SPANISH or ENGLISH. All submissions will be reviewed by experts in the field. Based on reviewers’ assessments, a submission may be recommended to be accepted for oral presentation (typically well-evaluated articles that describe research with clear results) or for poster session and a quick oral presentation (usually well-evaluated articles describing work in progress).

All submissions must be in Adobe Portable Document Format (PDF) and must follow the article formatting rules provided by the Brazilian Computing Society (SBC). The models for Microsoft Office Word, OpenOffice and Latex can be downloaded at:

Submissions to the main track must be made via Easychair using the following URL:

The conference proceedings will be published in the online journal CEUR-WS.

*** WTDO

WTDO 2019 will accept research proposals at master and doctoral level, and will be held during Ontobras 2019, in Porto Alegre. Master or PhD students interested in participating in detailed discussions about their ongoing research at WTDO are invited to submit their research proposal and research sheet.

The Research Sheet must appear on the first 2 pages of the submission and must follow the template available at:

The Research Proposal should appear on the 3rd page of the submission, and should occupy a maximum of 6 additional pages, including references (each submission must contain a maximum of 8 pages, including the research sheet and proposal). The pages of the research proposal must follow the TEMPLATE of the Brazilian Computing Society (SBC). Templates for MS Word, LibreOffice and LaTeX can be downloaded from the SBC website:

Submissions should be written in PORTUGUESE, SPANISH or ENGLISH, in a PDF file. The research proposals accepted for presentation in WTDO will be published along with the proceedings of Ontobras.

Submissions to WTDO must be made via Easychair as well, through the following URL:

In addition, the research advisers should send an e-mail to stating that they are aware of and agree to the submission of work to WTDO 2019.

The same manuscript (text or title) can not be submitted on both Ontobras tracks. Research proposals related to theses and dissertations already defended or with a date of defense planned for before the event will not be considered.

============================== REVIEW OF WTDO SUBMISSIONS ==============================

The submitted proposals will be analyzed by the Ontobras steering committee. The review will take into account both its originality, clarity and relevance concerning the definition of the problem and purpose of the research, the analysis of the state of the art and related works, the adequacy of the research method used, the quality of the text, the potential to advance the Ontology research area, and whether or not the work is in a phase in which the student can benefit from participating in the Workshop (so that research proposals that are already concluded or defended will not be accepted). Submissions that are not selected for presentation at WTDO will also receive feedback from reviewers.

============================== PRESENTATION ON WORKSHOP ==============================

Accepted papers must be presented exclusively by the candidate student, at the Workshop during Ontobras. The student will receive feedback from a board of senior researchers in the area, and the session will be open to all Ontobras participants. All presenters should attend all Workshop sessions in order to create a qualified venue for rich discussions. The schedule will provide the presenters with substantial time for discussions and questions by participating researchers and other students.

WTDO 2019 presentations will be evaluated in loco by previously designated area experts, and the results of evaluations (considering both submission and presentation) will serve as a basis for selection of the 2 best papers (1 at master level and 1 at doctoral level) of WTDO 2019. The best papers will be announced during the event, and will receive as a prize the exemption of the registration fee in the next edition of Ontobras, valid exclusively for the student author of the selected research.
