Call for Papers


Ontology is a cross-disciplinary field concerned with the study of concepts and theories that support the building of shared conceptualizations of 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 and many others.

The Brazilian Conference on Ontologies (Ontobras) foresees an opportunity and scientific environment in which researchers and practitioners from Information Sciences and Computer Science can exchange the theories, methodologies, languages, tools and experience related to the ontology development and application. In particular, the community has put forward efforts in integrating previous events on Ontologies that happened in Brazil in recent years, in order to create a unique highly scientifically qualified international forum for presenting and discussing the subject in Brazil.

Therefore, we provide a non-comprehensive list of areas and researchers’ communities from which we expect to receive submissions:

  • Information Science – working with ontologies, thesauri, knowledge management among other applications;
  • Databases – working with semantic data integration, linked open data, among other applications;
  • Artificial Intelligence – working with knowledge based systems, agents, ontology reasoning, among other applications;
  • Software Engineering – working with conceptual modelling, Business Process Models, among other applications;
  • Informatics in Education –  working with  Educational Ontologies, Semantic Web-based Educational Standards, among other applications;
  • Linguistics and philosophy –  working with natural language processing using ontologies, theories of representation, among other applications.

Researchers and practitioners are invited to submit theoretical, technical and practical research contributions that directly or indirectly address the issues above. Particularly welcome are e-science, life-sciences, e-business and cultural applications.


We are interested in the various aspects of the field, from its philosophical and theoretical foundations to the new technologies and innovative applications.

In this edition, Ontobras is opened to submissions in two categories:

  • Full papers (maximum 12 pages) written in English and describing work with clear demonstrated results. Accepted full papers will be invited for oral presentation. The best full papers will be invited to be extended for publication in an influential international journal (still in negotiation).
  • Short papers (maximum 6 pages) written in Portuguese, English, or Spanish and describing ongoing work. Accepted short papers will be invited for poster presentations.

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 should be done via Easychair:

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


Main track submission deadline:  July 10, 2015  July 15, 2015
