Sistemi integrati per la visualizzazione immersiva

2015

Il disegno dell’architettura ha, tra i suoi obiettivi disciplinari, quello di “far vedere” lo spazio, sia nelle sue declinazioni temporali, sia in quelle descrittive di forme, luce, colori e materiali, caratteri connotativi che cerca di riprodurre grazie a metodi di proiezione codificati e tecniche di rappresentazione in continuo mutamento. Tra le tecniche di rappresentazione informatica la visualizzazione immersiva consente di ruotare lo sguardo, in tempo reale, all’interno di uno spazio, cercando di superare i limiti della rappresentazione piana, simulando la visione sferica dello spazio. La tecnica può essere utilizzata sia per vedere la realtà esistente, tramite immagini fotografiche, s…

$$PO^2$$ - A Process and Observation Ontology in Food Science. Application to Dairy Gels

2016

This paper focuses on the knowledge representation task for an interdisciplinary project called Delicious concerning the production and transformation processes in food science. The originality of this project is to combine data from different disciplines like food composition, food structure, sensorial perception and nutrition. Available data sets are described using different vocabularies and are stored in different formats. Therefore there is a need to define an ontology, called \(PO^2\) (Process and Observation Ontology), as a common and standardized vocabulary for this project. The scenario 6 of the NeON methodology was used for building \(PO^2\) and the core component is implemented i…

Conceptual graph operations for formal visual reasoning in the medical domain

2014

International audience; Objective - Conceptual graphs (CGs) are used to represent clinical guidelines because they support visual reasoning with a logical background, making them a potentially valuable representation for guidelines.Materials and methods - Conceptual graph formalism has an essential and basic component: a formal vocabulary that drives all of the other mechanisms, notably specialization and projection. The graph's theoretical operations, such as projection, rules, derivation, constraints, probabilities and uncertainty, support diagrammatic reasoning.Results - A conceptual graph's graphical user interface includes a multilingual vocabulary management, some query and decision-m…

Codebook is an effective image representation method. By clustering in local image descriptors, a codebook is shown to be a distinctive image feature and widely applied in object classification. In almost all existing works on codebooks, the building of the visual vocabulary follows a basic routine, that is, extracting local image descriptors and clustering with a user-designated number of clusters. The problem with this routine lies in that building a codebook for each single dataset is not efficient. In order to deal with this problem, we investigate the influence of vocabulary sizes on classification performance and vocabulary universality with the kNN classifier. Experimental results in…

Ontology languages for the semantic web: A never completely updated review

2006

This paper gives a never completely account of approaches that have been used for the research community for representing knowledge. After underlining the importance of a layered approach and the use of standards, it starts with early efforts used for artificial intelligence researchers. Then recent approaches, aimed mainly at the semantic web, are described. Coding examples from the literature are presented in both sections. Finally, the semantic web ontology creation process, as we envision it, is introduced.

Rethinking Political Representation from the Perspective of Rhetorical Genres

2019

This article is a thought experiment. It constructs ideal types of political representation in the sense of Max Weber. Inspired by Quentin Skinner and others, the aim is to give a rhetorical turn to contemporary debates on representation. The core idea is to claim an ‘elective affinity’ (Wahlverwandschaft, as Weber says following Goethe) between forms of representation and rhetorical genres of their justification. The four ideal types of political representation are designated as plebiscitary, diplomatic, advocatory, and parliamentary, corresponding to the epideictic, negotiating, forensic, and deliberative genres of rhetoric as the respective ways to plausibly appeal to the audience. I dis…

Domain Specific Knowledge Representation for an Intelligent Tutoring System to Teach Algebraic Reasoning

2012

Translation of word problems into symbolic notation is one of the most challenging steps in learning the algebraic method. This paper describes a domain-specific knowledge representation mechanism to support Intelligent Tutoring Systems (ITS) which focus on this stage of the problem solving process. The description language proposed is based on the concept of a hypergraph and makes it possible to simultaneously a) represent all potential algebraic solutions to a given word problem; b) keep track of the student's actions; c) provide automatic remediation; and d) unequivocally determine the current state of the resolution process. An experimental evaluation with students at a public school su…

THE SCUOLA OFFICINA MECCANICA IN VILLAGGIO MONTE DEGLI ULIVI IN RIESI. READING AND ANALYSIS THROUGH SURVEYING.

2017

This research analyses in depth the project of one of the most representative work of the Modern Architectural Movement in Sicily – the Scuola Officina Meccanica, located in Villaggio Monte degli Ulivi, in Riesi (CL), designed by the architect Leonardo Ricci between 1962 and 1968. The main objective is to contribute to the conservation of the architectural work through its analysis and study for a careful and conscious restoration. The research methodology aimed to retrace the compositional and geometric principles that defined the design process and its unique configuration.

A Semantic Publish/Subscribe Approach for U-VR Systems Interoperation

2008

As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrastructure that lies on a description logics reasoner and OWL ontologies for managing heterogeneous event models and performing the matching of events and subscriptions in such U-VR systems.

The teaching of the Valencian language and linguistic prejudices. A case study in a secondary school in Plana Utiel-Requena

2020

[EN] The present research deals with the question of the teaching of Valencian in the Spanish-speaking areas where the LUEV (1983) is in force, which determines the possibility of exemption from the subject of Valencian. Specifically, we approach the question of the beliefs and social representations on the language and its teaching from a case study carried out in a secondary school of the city of Requena. The aim of the study is to identify and differentiate the linguistic attitudes towards the Valencian language in this sociolinguistic context and it is an opportunity to present an educational change. The results of this study respond to the ideas of the students and the native teachers …
