  1. UFO: Unified Foundational Ontology.Giancarlo Guizzardi, Alessander Bottes Benevides, Claudemir M. Fonseca, João Paulo A. Almeida, Tiago Prince Sales & Daniele Porello - 2022 - Applied ontology 1 (17):167-210.
    The Unified Foundational Ontology (UFO) was developed over the last two decades by consistently putting together theories from areas such as formal ontology in philosophy, cognitive science, linguistics, and philosophical logics. It comprises a number of micro-theories addressing fundamental conceptual modeling notions, including entity types and relationship types. The aim of this paper is to summarize the current state of UFO, presenting a formalization of the ontology, along with the analysis of a number of cases to illustrate the application of (...)

    Types and Taxonomic Structures in Conceptual Modeling: A Novel Ontological Theory and Engineering Support.Giancarlo Guizzardi, Tiago Prince Sales, Claudenir M. Fonseca & Daniele Porello - 2021 - Data and Knowledge Engineering 1 (134):101891.
    Types are fundamental for conceptual modeling and knowledge representation, being an essential construct in all major modeling languages in these fields. Despite that, from an ontological and cognitive point of view, there has been a lack of theoretical support for precisely defining a consensual view on types. As a consequence, there has been a lack of precise methodological support for users when choosing the best way to model general terms representing types that appear in a domain, and for building sound (...)

    A Core Ontology for Economic Exchanges.Daniele Porello, Giancarlo Guizzardi, Tiago Prince Sales & Glenda C. M. Amaral - 2020 - In Gillian Dobbie, Ulrich Frank, Gerti Kappel, Stephen W. Liddle & Heinrich C. Mayr (eds.), Conceptual Modeling - 39th International Conference, {ER} 2020, Vienna, Austria, November 3-6, 2020, Proceedings. Lecture Notes in Computer Science 12400. pp. 364-374.
    In recent years, there has been an increasing interest in the development of well-founded conceptual models for Service Management, Accounting Information Systems and Financial Reporting. Economic ex- changes are a central notion in these areas and they occupy a prominent position in frameworks such as the Resource-Event Action (REA) ISO Standard, service core ontologies (e.g., UFO-S) as well as financial stan- dards (e.g. OMG’s Financial Industry Business Ontology - FIBO). We present a core ontology for economic exchanges inspired by a (...)

  4. An Ontological Account of the Action Theory of Economic Exchanges.Daniele Porello, Giancarlo Guizzardi, Tiago Prince Sales, Glenda C. M. Amaral & Nicola Guarino - 2020 - In Proceedings of 14th International Workshop on Value Modelling and Business Ontologies, Brussels, Belgium, January 16-17, 2020. pp. 157-169.
    In recent years, there has been an increasing interest in thedevelopment of ontologically well-founded conceptual models for Information Systems in areas such as Service Management, Accounting Information Systems and Financial Reporting. Economic exchanges are central phenomena in these areas. For this reason, they occupy a prominent position in modelling frameworks such as the REA (Resource-EventAction) ISO Standard as well as the FIBO (Financial Industry BusinessOntology). In this paper, we begin a well-founded ontological analysisof economic exchanges inspired by a recent ontological (...)

  5. Endurant Types in Ontology-Driven Conceptual Modeling: Towards OntoUML 2.0.Giancarlo Guizzardi, Tiago Prince Sales, Claudenir M. Fonseca, Daniele Porello, Joao Paulo Almeida & Nicola Guarino - 2018 - In J. C. Trujillo, K. C. Davis, X. Du, Z. Li, T. W. Ling, G. Li & M. L. Lee (eds.), Conceptual Modeling - 37th International Conference, {ER} 2018, Xi'an, China, October 22-25, 2018, Proceedings. Springer. pp. 136--150.
    For over a decade now, a community of researchers has contributed to the development of the Unified Foundational Ontology (UFO) - aimed at providing foundations for all major conceptual modeling constructs. This ontology has led to the development of an Ontology-Driven Conceptual Modeling language dubbed OntoUML, reflecting the ontological micro-theories comprising UFO. Over the years, UFO and OntoUML have been successfully employed in a number of academic, industrial and governmental settings to create conceptual models in a variety of different domains. (...)

  6. Ontological Analysis and Redesign of Security Modeling in ArchiMate.Ítalo Oliveira, Tiago Prince Sales, João Paulo A. Almeida, Riccardo Baratella, Mattia Fumagalli & Giancarlo Guizzardi - forthcoming - PoEM 2022: The Practice of Enterprise Modeling 2022, Proceedings:1-16.
    Enterprise Risk Management and security have become a fundamental part of Enterprise Architecture, so several frameworks and modeling languages have been designed to support the activities associated with these areas. Archi- Mate’s Risk and Security Overlay is one of such proposals, endorsed by The Open Group. We investigate the capabilities of the proposed security-related con- structs in ArchiMate with regard to the necessities of enterprise security modeling. Our analysis relies on a well-founded reference ontology of security to uncover ambiguity, missing (...)
