Formal Models of Knowledge Diversity
The First International Workshop on Formal Models of Knowledge Diversity will be a part of JOWO 2022 (August 15-19, 2022 ).
FMKD@JOWO intends to create a space of confluence and a forum for discussion for researchers interested in knowledge diversity in a wide sense, including diversity in terms of diverging perspectives, different beliefs, semantic heterogeneity and others. The importance of understanding and handling the different forms of diversity that manifest between knowledge formalisations (ontologies, knowledge bases, or knowledge graphs) is widely recognised and has led to the proposal of a variety of systems of representation, tackling overlapping aspects of this phenomenon.
Besides understanding the phenomenon and considering formal models for the representation of knowledge diversity, we are interested in the variety of reasoning problems that emerge in this context, including jointly reasoning with possibly conflicting sources, interpreting knowledge from alternative viewpoints, consolidating the diversity as uncertainty, reasoning by means of argumentation between the sources and pursuing knowledge aggregations among others.
A non-exhaustive list of topics of interest for the workshop:
Philosophical and cognitive analysis of knowledge diversity.
Formal models for the representation of knowledge diversity.
Ontological approaches capturing multiple perspectives and viewpoints.
Context and concept formation in such systems.
Consistency (or not) in multi-perspective systems; assessment and mitigation of inconsistencies.
Communication between knowledge-diverse systems.
Argumentation-based approaches for dealing with inconsistency
Aggregation of diverse or inconsistent knowledge; judgement aggregation.
Uncertainty in the context of knowledge diversity.
Applications of formal models of knowledge diversity.
The workshop will take place on Friday, the 19th of August (Room 1)

August 15-19, 2022 – JOWO
We encourage three types of contributions:
Full research paper: Submitted papers must not exceed 14 pages excluding the bibliography, and must include an abstract of no more than 300 words. Please, note that the minimum length is 10 pages.
Short paper: Submitted papers must not exceed 6 pages excluding the bibliography, and must include an abstract of no more than 300 words. Please, note that the minimum length is 5 pages (including the bibliography).
Extended abstracts (presentation only) should be 2-4 pages long including the bibliography. Please, note that extended abstracts will not be included in the CEUR proceedings.
All papers must be original and not submitted to or accepted by any other workshop, conference or journal. Note, that for inclusion in the JOWO proceedings, short and position papers are required to be at least 5 pages long. All contributions will be peer-reviewed, and the review process will be managed in a collaborative and transparent manner using the EasyChair System as part of the JOWO organisation.
The submission link is https://easychair.org/conferences/?conf=jowo2022
Papers should be submitted non-anonymously in PDF format in compliance with the new 1-column CEUR-ART Style. Word and Latex templates can be found at
All contributions to JOWO workshops (full and short papers) will be published in a joint CEUR proceedings volume, compare:
