5th International Workshop on Foundational Ontology (FOUST) Website: https://foust.inf.unibz.it/foust5/ CFP - Important dates ⁃ Submission deadline: July 3, 2021 ⁃ Review notification: August 9, 2021 ⁃ Camera ready: August 23, 2021 ⁃ Workshop: September, 2021 (exact dates to be confirmed) About The 5th Workshop on Foundational Ontology (FOUST V) is co-located with the 12th International Conference on Formal Ontologies in Information Systems (FOIS 2021), to take place in September 2021 and hosted by the Bolzano Summer of Knowledge. Foundational ontologies are attempts to systematise those categories of thought or reality which are common to all or almost all subject-matters. Commonly considered examples of such categories include ‘object’, ‘quality’, ‘function’, ‘role’, ‘process’, ‘event’, ‘time’, and ‘place’. Amongst existing foundational ontologies, there is both a substantial measure of agreement and some dramatic disagreements. There is currently no uniform consensus concerning how a foundational ontology should be organised, how far its ‘reach’ should be (e.g., is the distinction between physical and non-physical entities sufficiently fundamental to be included here?), and even what role it should play in relation to more specialised domain ontologies. The purpose of this workshop is to provide a forum for researchers and stakeholders to present work on specific foundational ontologies as well as their relations to each other and to the wider ontological enterprise, but also topics related to foundational questions in ontology engineering Workshop topics (among others) ⁃ Changes to existing foundational ontologies / extension by new modules ⁃ Novel research on any specific category or topic usually covered by foundational ontology (e.g., functions, roles, time, mereology, ontological dependence, constitution) ⁃ Theoretical results about specific foundational ontologies (e.g., consistency proofs, modularizations, etc. ) ⁃ Application results of foundational ontologies in AI, the Semantic Web, Linguistics, etc. ⁃ Comparison and alignments of foundational ontologies ⁃ Relationship between foundational ontologies and domain ontologies Submissions We encourage two 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. 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. The minimum length is 5 pages Papers should be submitted non-anonymously in PDF format in compliance with the new 1-column CEUR-ART Style, which can be found at https://ceurws.wordpress.com/2020/03/31/ceurws-publishes-ceurart-paper-style/ The Easychair submission page can be found at https://easychair.org/conferences/?conf=jowo2021 (select the track “Workshop on Foundational Ontology”) All contributions to the workshop will be published in a joint CEUR proceedings volume, compare: ⁃ JOWO 2020: http://ceur-ws.org/Vol-2708/ ⁃ JOWO 2019: http://ceur-ws.org/Vol-2518/ ⁃ JOWO 2018: http://ceur-ws.org/Vol-2205/ Workshop policy FOUST 2021 is planned as a hybrid event. Hence, there will be a physical meeting in Bolzano which hopefully most will be able to join. However, given the uncertainty about travel in September we will make arrangements for remote participation. If the physical meeting cannot be held due to social restrictions, the workshop will go fully virtual.
