============================
16th International Conference on Formal Ontology in Information Systems (FOIS 2026)
21–25 September 2026, Vitória, ES, Brazil – 9 September 2026, Online
Website: https://www.foisconference.org/
============================
FOIS is the flagship conference of the International Association for Ontology and its Applications (IAOA) a non-profit organization promoting interdisciplinary research and international collaboration in formal ontology.
FOIS is a meeting point for all researchers with an interest in formal ontology. Formal ontology is the systematic study of the types of entities and relations making up the domains of interest represented in modern information systems. The conference encourages submission of high quality, not previously published results on both theoretical issues and practical advancements. FOIS 2026 will have distinct tracks for foundational issues, ontology applications and methods, and domain ontologies.
FOIS aims to be a nexus of interdisciplinary research and communication for researchers from many domains engaging with formal ontology. Common application areas include conceptual modeling, database design, knowledge engineering and management, software engineering, organizational modeling, artificial intelligence, robotics, computational linguistics, the life sciences, bioinformatics and scientific research in general, geographic information science, information retrieval, library and information science, as well as the Semantic Web.
FOIS 2025 will be held both online and in Vitória, ES, Brazil, organized by the Federal University of Espírito Santo.

FOIS Journal-First Papers
The FOIS 2026 journal-first track aims to showcase and discuss with the FOIS community recently published studies related and relevant to formal and applied ontology. The rationale of the journal-first track is to provide an opportunity to present and discuss already published results that have not yet been presented at a conference.
We invite submissions in forms of extended abstracts of journal papers that have been published or have been accepted for publication but have not been presented at a conference or workshop before.
Accepted proposals will be presented at FOIS 2026 with an accompanying (optional) poster session, either on-site or online, depending on the preferences of the author(s). For each accepted proposal, a short abstract will be published on the conference website along with a link to the original publication. Presentations can be either onsite or online. However, at least one author is required to register for the conference to present the research.
Submission Instructions
Individual submissions must be done using EasyChair, and include:
A cover page (single page) comprising:
the original title of the journal article;
authors;
bibliographic references of the paper, e.g. DOI of the original publication or, alternatively, a link to the publication at the journal’s website;
and a statement that this article is not an extension of an earlier ontology-focused conference or workshop paper
A one-page abstract of the paper. The abstract should describe the contributions of the paper, discuss the relevance of the paper to applied/formal ontology, and explain the impacts of the results.
The full article is to be uploaded as supplementary material.
The materials must be submitted through the EasyChair conference system at: https://easychair.org/conferences/?conf=fois2026
Submissions (i.e. cover page + abstract) must follow the one-column CEUR-ART style formatting. The CEUR-ART Overleaf template can be found at: https://www.overleaf.com/latex/templates/template-for-submissions-to-ceur-workshop-proceedings-ceur-ws-dot-org/wqyfdgftmcfw.
