1062The benefits of prototypes: The case of medical conceptsReti, Saperi E Linguaggi, The Italian Journal of Cognitive Sciences, 2017 3. 2017.In the present paper, we shall discuss the notion of prototype and show its benefits. First, we shall argue that the prototypes of common-sense concepts are necessary for making prompt and reliable categorisations and inferences. However, the features constituting the prototype of a particular concept are neither necessary nor sufficient conditions for determining category membership; in this sense, the prototype might lead to conclusions regarded as wrong from a theoretical perspective. That be…Read more

807Conceptual Spaces for Cognitive Architectures: A Lingua Franca for Different Levels of RepresentationBiologically Inspired Cognitive Architectures 19 1-9. 2017.During the last decades, many cognitive architectures (CAs) have been realized adopting different assumptions about the organization and the representation of their knowledge level. Some of them (e.g. SOAR [35]) adopt a classical symbolic approach, some (e.g. LEABRA[ 48]) are based on a purely connectionist model, while others (e.g. CLARION [59]) adopt a hybrid approach combining connectionist and symbolic representational levels. Additionally, some attempts (e.g. biSOAR) trying to extend the re…Read more

327Rappresentare i disordini mentali mediante ontologieApprendimento, Cognizione E Tecnologia. 2016.Come è emerso dall’analisi filosofica e dalla ricerca nelle scienze cogni- tive, la maggior parte dei concetti, tra cui molti concetti medici, esibisce degli “effetti prototipici” e non riesce ad essere definita nei termini di condizioni necessarie e sufficienti. Questo aspetto rappresenta un problema per la pro- gettazione di ontologie in informatica, poiché i formalismi adottati per la rap- presentazione della conoscenza (a partire da OWL – Web Ontology Langua- ge) non sono in grado di rende…Read more

1008Dealing with Concepts: from Cognitive Psychology to Knowledge RepresentationFrontiers of Psychological and Behevioural Science 2 (3): 96-106. 2013.Concept representation is still an open problem in the field of ontology engineering and, more generally, of knowledge representation. In particular, the issue of representing “non classical” concepts, i.e. concepts that cannot be defined in terms of necessary and sufficient conditions, remains unresolved. In this paper we review empirical evidence from cognitive psychology, according to which concept representation is not a unitary phenomenon. On this basis, we sketch some proposals for concept…Read more

490Ontologies, Disorders and PrototypesIn Cristina Amoretti, Marcello Frixione, Antonio Lieto & Greta Adamo (eds.), Proceedings of IACAP 2016, . 2016.As it emerged from philosophical analyses and cognitive research, most concepts exhibit typicality effects, and resist to the efforts of defining them in terms of necessary and sufficient conditions. This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field (such as, in the first place, the Web Ontology Language - OWL) do not allow for the representation of concep…Read more

67The Spirit of Cocktails: On the Conceptual Structure of Cocktail RecipesHumana.Mente - Journal of Philosophical Studies 38 (13): 37-59. 2020.In this paper, we discuss the conceptual structure of cocktail recipes. This topic involves engaging questions for philosophers and food theorists due to some peculiar characteristics of cocktail recipes, such as the fact that they are standardised by international associations but, nonetheless, vagueness in some elements of the recipes introduces a degree of variability between cocktails of the same type. Our proposal is that a classical theory of concepts is unable to account for such peculiar…Read more

1241Representing Concepts in Formal Ontologies: Compositionality vs. Typicality Effects"Logic and Logical Philosophy 21 (4): 391-414. 2012.The problem of concept representation is relevant for many sub-fields of cognitive research, including psychology and philosophy, as well as artificial intelligence. In particular, in recent years it has received a great deal of attention within the field of knowledge representation, due to its relevance for both knowledge engineering as well as ontology-based technologies. However, the notion of a concept itself turns out to be highly disputed and problematic. In our opinion, one of the causes …Read more

24Formal Ontologies and Semantic Technologies: A “Dual Process” Proposal for Concept RepresentationPhilosophia Scientiae 18 139-152. 2014.Pour la plupart des systèmes de représentation de la connaissance orientés concept, l’un des problèmes principaux relève de la commodité technique. A savoir, la représentation de connaissance en termes prototypiques, tout comme la possibilité d’exploiter des formes de raisonnement conceptuel basées sur la typicalité, ne sont pas autorisées. Au contraire, dans les sciences cognitives, il existe des données en faveur de concepts prototypiques, et des formes non-monotoniques de raisonnement concept…Read more

41Representing wine concepts: A hybrid approachApplied ontology 15 (4): 475-491. 2020.Wines with geographical indication can be classified and represented by such features as designations of origin, producers, vintage years, alcoholic strength, and grape varieties; these features allow us to define wines in terms of a set of necessary and/or sufficient conditions. However, wines can also be identified by other characteristics, involving their look, smell, and taste; in this case, it is hard to define wines in terms of necessary and/or sufficient conditions, as wine concepts exhib…Read more

647Can the g Factor Play a Role in Artificial General Intelligence Research?In Davide Serpico & Marcello Frixione (eds.), Proceedings of the Society for the Study of Artificial Intelligence and Simulation of Behaviour 2018, . pp. 301-305. 2018.In recent years, a trend in AI research has started to pursue human-level, general artificial intelli-gence (AGI). Although the AGI framework is characterised by different viewpoints on what intelligence is and how to implement it in artificial systems, it conceptualises intelligence as flexible, general-purposed, and capable of self-adapting to different contexts and tasks. Two important ques-tions remain open: a) should AGI projects simu-late the biological, neural, and cognitive mecha-nisms r…Read more

343Spazi multidimensionali per la rappresentazione semanticaPenguin-Random House. 2019.Nel campo delle scienze cognitive molti oggi condividono l’ipotesi che siano necessari differenti tipi di rappresentazioni per modellare i sistemi cognitivi sia naturali, sia artificiali. Si considerino le rappresentazioni basate su reti neurali, i formalismi simbolici e rappresentazioni analogiche quali rappresentazioni diagrammatiche o modelli mentali. Tutti questi metodi hanno successo nello spiegare e modellare alcune classi di fenomeni cognitivi, ma nessuno è in grado di rendere conto di tu…Read more

This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field do not allow for the representation of concepts in terms of typical traits.

11Concepts and Fat PlantsProtoSociology 30 152-166. 2013.During the last decades it has emerged that concepts probably do not constitute a homogeneous set of entities from a psychological point of view. Various divides can be drawn between different types of concepts. Probably, the main empirical achievement in this field has been the inadequacy of the so-called “classical view”: most concepts cannot be characterised in terms of sets of necessary and sufficient conditions; rather, they exhibit typicality effects. In this chapter I will suggest that ty…Read more

629Introduzione alle Logiche ModaliLaterza. 2016.La logica modale è nata per studiare i ragionamenti su ciò che è possibile e ciò che è necessario. Negli ultimi decenni, a partire dal lavoro di logici e filosofi quali Rudolf Carnap, Saul Kripke e David Lewis, la sua applicazione è stata progressivamente estesa ad altri ambiti, quali il ragionamento sul tempo, sulla conoscenza e sui sistemi di norme. Queste ricerche hanno condotto a un complesso e intrigante dialogo con alcune fondamentali branche della filosofia: la metafisica, l’epistemologia…Read more

64Tractable competenceMinds and Machines 11 (3): 379-397. 2001.In the study of cognitive processes, limitations on computational resources (computing time and memory space) are usually considered to be beyond the scope of a theory of competence, and to be exclusively relevant to the study of performance. Starting from considerations derived from the theory of computational complexity, in this paper I argue that there are good reasons for claiming that some aspects of resource limitations pertain to the domain of a theory of competence.

100On the advantage (if any) and disadvantage of the conceptual/nonconceptual distinction for cognitive scienceMinds and Machines 20 (1): 29-45. 2010.In this article we question the utility of the distinction between conceptual and nonconceptual content in cognitive science, and in particular, in the empirical study of visual perception. First, we individuate some difficulties in characterizing the notion of “concept” itself both in the philosophy of mind and cognitive science. Then we stress the heterogeneous nature of the notion of nonconceptual content and outline the complex and ambiguous relations that exist between the conceptual/noncon…Read more

73Art, the brain, and family resemblances: Some considerations on neuroaestheticsPhilosophical Psychology 24 (5). 2011.The project of neuroaesthetics could be interpreted as an attempt to identify a ?neural essence? of art, i.e., a set of necessary and sufficient conditions formulated in the language of neuroscience, which define the concept art . Some proposals developed within this field can be read in this way. I shall argue that such attempts do not succeed in individuating a neural definition of art. Of course, the fact that the proposals available for defining art in neural terms do not work does not mean …Read more
