KoDis: Workshop on Knowledge Diversity
==================================

Co-located with the 20th International Conference on Principles of Knowledge Representation and Reasoning (KR 2023),
September 2-8, 2023 Rhodes, Greece

https://kodis23.wordpress.com

== IMPORTANT DATES ==

Workshop paper submission deadline: May 31, 2023 (AOE)
Workshop paper notification: July 4, 2023 (AOE)
Workshop dates: September 2-4, 2023

== AIMS AND SCOPE ==

KoDis 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 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. The following is a non-exhaustive list of topics of interest.

- 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.

== SUBMISSIONS ==

We encourage three types of contributions:

- Full research papers: 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 papers: 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.

== PUBLICATION==

Accepted papers will be published in CEUR Workshop Proceedings.

The authors of selected papers will be invited to prepare an extended version to a Special Issue on “Knowledge Diversity” in the Künstliche Intelligenz Journal, the German Journal of Artificial Intelligence (Springer).

-- FCA4AI (Tenth Edition) --
``What can FCA do for Artificial Intelligence?''
co-located with IJCAI-ECAI 2022, Vienna, Austria
July 23 or 24 2022
http://www.fca4ai.hse.ru/2022

-------------------------------------------------------------------------------------------------------------------

General Information.

The preceding editions of the FCA4AI Workshop (from ECAI 2012 until IJCAI 2021) showed that many researchers working in Artificial Intelligence are indeed interested by powerful techniques for classification and data mining provided by Formal Concept Analysis. Again, we have the chance to organize the 10th edition of the workshop in Vienna, co-located with the IJCAI-ECAI 2022 Conference.

Formal Concept Analysis (FCA) is a mathematically well-founded theory aimed at data analysis and classification. FCA allows one to build a concept lattice and a system of dependencies (implications and association rules) which can be used for many AI needs, e.g. knowledge processing, knowledge discovery, knowledge representation and reasoning, ontology engineering as well as information retrieval, recommendation, social network analysis and text processing. Thus, there are many ``natural links'' between FCA and AI.

Recent years have been witnessing increased scientific activity around FCA, in particular a strand of work emerged that is aimed at extending the possibilities of plain FCA w.r.t. knowledge processing, such as work on pattern structures and relational context analysis, as well as on hybridization with other formalisms. These extensions are aimed at allowing FCA to deal with more complex than just binary data, for solving complex problems in data analysis, classification, knowledge processing... While the capabilities of FCA are extended, new possibilities are arising in the framework of FCA.

As usual, the FCA4AI workshop is dedicated to the discussion of such issues, and in particular:
- How can FCA support AI activities in knowledge discovery, knowledge representation and reasoning, machine learning, natural language processing...
- By contrast, how the current developments in AI can be integrated within FCA to help AI researchers solve complex problems in their domain,
- Which role can be played by FCA in the new trends in AI, especially in ML, XAI, fairness of algorithms, and ``hybrid systems'' combining symbolic and subsymbolic approaches.

TOPICS OF INTEREST include but are not limited to:

- Concept lattices and related structures: pattern structures, relational structures, distributive lattices.
- Knowledge discovery and data mining:
pattern mining, association rules, attribute implications, subgroup discovery, exceptional model mining, data dependencies, attribute exploration, stability, projections, interestingness measures, MDL principle, mining of complex data, triadic and polyadic analysis.
- Knowledge and data engineering: knowledge representation, reasoning, ontology engineering, mining the web of data, text mining, data quality checking.
- Analyzing the potential of FCA in supporting hybrid systems: how to combine FCA and data mining algorithms, such as deep learning for building hybrid knowledge discovery systems, producing explanations, and assessing system fairness.
- Analyzing the potential of FCA in AI tasks such as classification, clustering, biclustering, information retrieval, navigation, recommendation, text processing, visualization, pattern recognition, analysis of social networks.
- Practical applications in agronomy, astronomy, biology, chemistry, finance, manufacturing, medicine...

The workshop will include time for audience discussion aimed at better understanding of of the issues, challenges, and ideas being presented.

IMPORTANT DATES:

Submission deadline: June 06 2022
Notification to authors: July 04 2022
