Formal ontology is here understood as the rigorous, axiomatic account of the nature and structure of what exists. While we deliberately avoid any metaphysical implications of the verb ‘to exist’, we share with the broad philosophical area of analytic metaphysics the fundamental notions that, due to their generality, allow us to explain and make explicit our ontological commitment on what exists. Such notions concern the basic kinds of entities (particulars, universals, objects, events, processes, actions, states of affairs, qualities, roles, relationships…), the basic kinds of relations among entities (parthood, identity, connection, dependence, constitution, causality…), the general issues of location, change, persistence and granularity in space and in time.

Keywords objects, events, processes, action, ontological relations, roles, states of affairs, tropes, change

We are interested in the ways social interaction is carried out in complex organizations and socio-technical systems (e.g. airports, coordination centres, emergency rooms, so-called ‘smart cities’) taking work, and technologically-mediated or aided work in particular, as a paradigmatic case. We pay particular attention to processes of techno-organizational change and innovation. At a more general level, we focus on the details of human action-in-interaction and human-machine interaction, with particular attention to nonverbal and affective aspects, and the role of tools and technologies.

Furthermore, we study the foundational properties – for instance identity, intentionality, persistence through time and change… – of collective and social entities, like roles, organizations, informal groups, norms, etc.

We are interested in understanding the connection between studies in cognitive sciences and in ontology. We investigate on the one hand the cognitive foundations of ontologies, i.e., the mechanisms behind the conceptualization of the world and the classification process (e.g., connections with theories of concepts and categorization, image schemas, etc.) and on the other hand the ontological foundations of cognitive theories including the ontological analysis of mental entities (e.g., desires, beliefs, intentions), conceptual spaces, prototypes, etc.

Our starting point is that the way agents (humans, non-human animals, cyborgs, artificial agents and robots) interact with the environment – via their cognitive and embodied capabilities – forms and, at the same time, depends on their conceptualization of the world that can be made explicit by means of ontologies.

We find that design activities are particularly challenging as they require to integrate information about the world (the fragment to be understood and/or modified), about the designer (the knowledge available, the expectations as well as the cognitive capabilities) and about the model (the perspective it takes, what it does or should contain, its envisioned use). No matter whether one designs industrial or administrative processes, devices or social objects, ontology is an essential tool to help understanding and organising the types of information that must be considered in this activity like, depending on the application domain, spatial, material, structural, functional, behavioural, procedural, agentive, cognitive and social information.

We aim at exploring the epistemological stance in formal ontology and knowledge representation. In particular, we are interested in two intertwined research directions: (i) the epistemological foundations of ontologies and (ii) the ontology of epistemology. A number of important topics are related to these points, for instance: the representation of empirical data, measurements, and observations together with their provenance and the reliability of the sources of information (both human and artificial, e.g. sensors) in the context in which data have been collected; the ontological analysis of epistemological concepts like argument, explanation, proof or, more generally, of how raw data are elaborated to produce new data; the integration of ontological approaches with machine learning and micro-sociological approaches, in particular in computer vision and sociable robotics.

Keywords
ontology of empirical data, observations, sensors, and provenance, representation of different perspectives on the same domain (contexts, granularity, resolution, ontological levels), epistemological foundations of ontologies and ontologies of epistemology

We do research in logics for knowledge representations, cognitive science, and for representing ontological concepts and theories. We work mainly on first-order theories, modal logics, and description logics. We also explore the application and advantages of non-classical logics in knowledge representation, cognitive science, and ontologies.

Overall, the aim is to develop expressive and clear logical systems that are well motivated and robust for modeling ontological and cognitive views.

We live in an era in which the rapid development of new technologies, especially digital media, makes it increasingly difficult to identify the rules to be applied in the different fields of society. Great technological innovations, like all great discoveries, do not limit themselves to adding novelty to the existing but shape it, give it new shape and content, creating a new dimension within which even the rules of law take on new content.

We are interested in facing the challenges of contemporary public law (regulatory issues, new jurisprudential trends and practices adopted by the sector Authorities), in an inter-sectoral perspective and according to a markedly international and European approach, through the use of the legal perspective and method compared.
