A novel and validated agile Ontology Engineering methodology for the development of ontology-based applications

The goal of this Thesis is to investigate the status of Ontology Engineering, underlining the main key issues still characterizing this discipline. Among these issues, the problem of reconciling macro-level methodologies with authoring techniques is pivotal in supporting novel ontology engineers. The latest approach characterizing ontology engineering methodologies leverages the agile paradigm to support collaborative ontology development and deliver efficient ontologies. However, so far, the investigations in the current support provided by these methodologies and the delivery of efficient ontologies have not been investigated. Thus, this work proposes a novel framework for the investigation of agile methodologies, with the objective of identifying the strong point of each agile methodology and their limitations. Leveraging on the findings of this analysis, the Thesis introduces a novel agile methodology – AgiSCOnt – aimed at tackling some of the key issues characterizing Ontology Engineering and weaknesses identified in existing agile approaches. The novel methodology is then put to the test as it is adopted for the development of two new domain ontologies in the field of health: the first is dedicated to patients struggling with dysphagia, while the second addresses patients affected by Chronic obstructive pulmonary disease.The goal of this Thesis is to investigate the status of Ontology Engineering, underlining the main key issues still characterizing this discipline.

Distributed Parameters Dynamic Model of a Solar Fresnel Collector Field

8th World CongressThe International Federation of Automatic ControlMilano (Italy) August 28 - September 2, 2011This paper describes a dynamic model for a linear Fresnel collector field of a solar refrigeration plant. The collector field concentrates solar radiations on a tube that heats up water that is used by an absorption machine to produce chilled air for refrigeration purposes. The model takes into account the solar radiation losses produced by the mirrors and the absorbing tube structure as well as the temperatures in 64 segments of the receiving tube and water. Although the dynamic model is of high dimension and nonlinear, the identification problem can be expressed as a linear problem in model parameters. The least square method was used for identification. The model was validated comparing the simulation results with the plant data for different operating conditions

Collaborative Ontology Engineering Methodologies for the Development of Decision Support Systems: Case Studies in the Healthcare Domain

New models and technological advances are driving the digital transformation of healthcare systems. Ontologies and Semantic Web have been recognized among the most valuable solutions to manage the massive, various, and complex healthcare data deriving from different sources, thus acting as backbones for ontology-based Decision Support Systems (DSSs). Several contributions in the literature propose Ontology engineering methodologies (OEMs) to assist the formalization and development of ontologies, by providing guidelines on tasks, activities, and stakeholders' participation. Nevertheless, existing OEMs differ widely according to their approach, and often lack of sufficient details to support ontology engineers. This paper performs a meta-review of the main criteria adopted for assessing OEMs, and major issues and shortcomings identified in existing methodologies. The key issues requiring specific attention (i.e., the delivery of a feasibility study, the introduction of project management processes, the support for reuse, and the involvement of stakeholders) are then explored into three use cases of semantic-based DSS in health-related fields. Results contribute to the literature on OEMs by providing insights on specific tools and approaches to be used when tackling these issues in the development of collaborative OEMs supporting DSS

An Ontology-Based Decision Support System to Foster Innovation and Competitiveness Opportunities of Health Tourism Destinations

The competitiveness of nature-based Health Tourism (NHT) industry, especially in the Alpine regions, is increasingly linked to the sustainability and exploitation of unique natural resources of tourism destinations, which often lack the access to knowledge and networks of stakeholders to improve their offerings. In this sense, the use of digital tools can open up further opportunities to reconsider value offerings and better access different knowledge resources and relationships within the industry network. This Chapter illustrates the collaborative design approach adopted in HEALPS2 for the development of an ontology-based Decision Support System for health tourism destinations. The resulting ontology aims to model the relationships between the available natural resources, the value offerings and the target groups of NHT destinations. Moreover, the Collaborative Design approach foresees the involvement of end-users (i.e. not only tourism destinations, but also the network of stakeholders, and the actual and potential future tourists) as both sources of knowledge and validators of the ontology and its outputs, aiming to inform decision-making processes in a shared knowledge model that leverages on digital tools

Minimalismo: pintura-suporte-espaço - o papel da arte na educação como possibilidade de transformar a percepção de si no espaço e do espaço em lugar

Anais do II Seminário Seminário Estadual PIBID do Paraná: tecendo saberes / organizado por Dulcyene Maria Ribeiro e Catarina Costa Fernandes — Foz do Iguaçu: Unioeste; Unila, 2014O presente trabalho expõe as contribuições do Programa Institucional de Bolsa de Iniciação à Docência (PIBID-ARTE) no processo de formação estética e cidadã de alunos do primeiro ano do ensino médio do Colégio Estadual Professora Roseli PiottoRoehrig - Londrina (PR), no segundo semestre de 2013. A partir de uma problematização puramente estética, voltada para a arte abstrata, propôs-se nessa experiência-aula, como processo/resultado, a apreensão dos elementos que estruturam e organizam as artes visuais, assim como a aplicabilidade destes elementos no espaço de inserção do aluno, possibilitando que os mesmos se reconhecessem como criadores e produtores de trabalhos em artes visuais, e que esses trabalhos contribuíssem afirmativamente para a melhoria do espaço coletiv

Digital and Strategic Innovation for Alpine Health Tourism

This open access book presents a set of practical tools and collaborative solutions in multi-disciplinary settings to foster the Alpine Space health tourism industry’s innovation and competitiveness. The proposed solutions emerge as the result of the synergy among health, environment, tourism, digital, policy and strategy professionals. The approach underlines the pivotal role of a sustainable and ecomedical use of Alpine natural resources for health tourism destinations, and highlights the need of integrating aspects of natural resources’ healing effects, a shared knowledge of Alpine assets through digital solutions, and frames strategic approaches for the long-term development of the sector. The volume exploits the results of the three-years long EU research project HEALPS 2, which involved several stakeholders from the health tourism, healthcare and sustainable tourism industries. This book is relevant for health tourism destinations and facilities (hotels, clinics, wellness and spa companies), regional and local authorities (policy makers), business support organizations, researchers involved in digital healthcare and geoinformatics

Left Ventricular “Diverticulum” in a Patient Affected by Galactosialidosis

We present the case of a 35-year-old man affected by the late juvenile form of galactosialidosis. He was known for a moderate pericardial effusion which remained unchanged in the last 12 months. Last follow-up transthoracic echocardiographic examination showed a bulging of the posterior and lateral wall of the left ventricle. This finding has never been described before in galactosialidosis

LA COMUNICAZIONE POLITICA SUI SOCIAL NETWORK: UN’ANALISI LINGUISTICA

Questo lavoro si propone di analizzare le scelte linguistiche dei soggetti politici che utilizzano Facebook e Twitter per rivolgersi al sempre più frammentato panorama dei potenziali elettori. In particolare, analizza le tendenze linguistiche comuni che questi social network hanno fatto emergere nel rapporto tra politica, web e lettori. Cominciando dall’analisi della presenza di parlamentari e senatori su Facebook e Twitter, si cerca di riassumere le principali caratteristiche delle due piattaforme, per giungere ad una classificazione dei testi prodotti attraverso di esse; si analizza la scrittura di post e tweet, sottolineando la presenza di espedienti tipici del mezzo e valutando il loro effetto sui lettori, e si studiano le scelte sintattiche e morfosintattiche in relazione alla struttura e alle possibilità dei due social network. In ultima analisi si osservano le scelte lessicali dei soggetti politici, studiandone i campi semantici e la quantità di tecnicismi. Infine, si cerca di compiere una valutazione delle due differenti tipologie di trasmesso scritto rinvenute nei campioni, osservando come ognuna di esse abbia uno scopo ben preciso nell’economia della comunicazione politica sui social network. Political communication policy in social networks: a language analysis  Daniele Spoladore This paper aims to analyze the linguistic choices of politicians who use Facebook and Twitter to address the increasingly fragmented landscape of potential voters. In particular, it analyzes the common language trends that these social networks have revealed in the relationship between politics, the web and readers. Starting from the analysis of the presence of MPs and senators on Facebook and Twitter, we try to summarize the key features of the two platforms, in order to arrive at a classification of the texts produced using them.  We analyzed posts and tweets, emphasizing the  typical characteristics of these means and evaluating their effect on readers, and we studied the syntactic and morpho-syntactic choices in relation to the structure and the possibilities offered by the two social networks. In the final analysis, we observed the lexical choices of politicians, studying the semantic fields and the amount of technicalities. Finally, we tried to make an assessment of two different types of writing found in the samples submitted, noting that each has a specific purpose in the economy of political communication on social networks.
