Le arti del costruire. Corporazioni, mestieri e regole nel Mediterraneo aragonese (XV-XVI secolo)

2010

Monografia che affronta lo studio delle corporazioni del settore edile nel bacino Mediterraneo di influenza aragonese tra XV e XVI secolo. Il volume è articolato in tre parti: uno sguardo d’insieme che traccia un quadro comparativo sulle associazioni di mestiere vincolate al mondo della costruzione nel vasto ambito di studio delineato (ma con un’attenzione a un più ampio contesto europeo), facendo emergere elementi di unicità e analogie, possibili modelli organizzativi di successo, articolazione delle professioni e rapporti di forza, rivalità e contrapposizioni, con una riflessione finale sul rapporto tra architetti e corporazione; la parte seconda (affidata dalla sottoscritta a un selezion…

Innovative techniques for survey and communication of cultural heritage

2008

This paper deals with the survey and communications of Cultural Heritage through the development of innovative methodologies. The case of study is the polychrome wooden ceiling in the “Magna” Hall of “Palazzo Steri”. The “Steri”, built in the XIVth century by the noble family Chiaromonte, is at the present the headquarter of the Rector’s Office of Palermo University. A 3D model of the wooden ceiling has initially been carried out with laser-scanning and digital photogrammetric techniques; successively a multimodal interactive guide has been realized. The guide is integrated to the 3D model, so that visitors can navigate the virtual representation of the ancient wood ceiling and achieve, int…

A Hybrid Recommender System for Cultural Heritage Promotion

2021

Assisting users during their cultural trips is paramount in promoting the heritage of a territory. Recommender Systems offer the automatic tools to guide users in their decision process, by maximizing the adherence of the proposed contents with the particular preferences of every single user. However, traditional recommendation paradigms suffer from several drawbacks which are exacerbated in Cultural Heritage scenarios, due to the extremely wide range of users behaviors, which may also depend on their different educational backgrounds. In this paper, we propose a Hybrid recommender system which combines the four most common recommendation paradigms, namely collaborative filtering, popularit…

Evaluation of customer satisfaction with the hospital catering system in the city of Palermo (Italy) [Valutazione della Customer Satisfaction nella “…

2009

Obiettivi: lo scopo dello studio è stato quello di rilevare la ”customer satisfaction” nella ristorazione ospedaliera di pazienti ricoverati in due strutture pubbliche (Azienda Ospedaliera Universitaria Policlinico e Presidio Ospedaliero Asl 6) ed in un Presidio Ospedaliero privato di Palermo, valutandone le differenze anche in relazione alla diversa tipologia di preparazione dei pasti, con “cucina centralizzata”, nel pubblico, ed “in loco”, nel privato. Metodi: l’indagine è stata realizzata con questionario a risposta multipla mediante intervista diretta, somministrato a 207 pazienti, su 227 presenti, che hanno collaborato all’inchiesta. Risultati: Giudizi favorevoli sono stati espressi so…

Sub-Symbolic Mapping of Cyc Microtheories in Data-Driven 'Conceptual' Spaces

2007

The presented work aims to combine statistical and cognitive-oriented approaches with symbolic ones so that a conceptual similarity relationship layer can be added to a Cyc KB microtheory. Given a specific microtheory, a LSA-inspired conceptual space is inferred from a corpus of texts created using both ad hoc extracted pages from the Wikipedia repository and the built-in comments about the concepts of the specific Cyc microtheory. Each concept is projected in the conceptual space and the desired layer of sub-symbolic relationships between concepts is created. This procedure can help a user in finding the concepts that are "sub-symbolically conceptually related" to a new concept that he wan…

Sono analizzati singole opere e contesti architettonici insieme alle figure dei maggiori protagonisti.

Probabilistic techniques for bridging the semantic gap in schema alignment

Connecting pieces of informations from heterogeneous sources sharing the same domain is an open challenge in Semantic Web, Big Data and business communities. The main problem in this research area is to bridge the expressiveness gap between relational databases and ontologies. In general, an ontology is more expressive and captures more semantic information behind data than a relational database does. On the other side, databases are the most common used persistent storage system and they grant benefits such as security and data integrity but they need to be managed by expert users. The problem is quite significant above all when enterprise or corporate ontologies are used to share infomation…

Bio-inspired Sensory Data Aggregation

2013

The Ambient Intelligence (AmI) research field focuses on the design of systems capable of adapting the surrounding environmental conditions so that they can match the users needs, whether those are consciously expressed or not [4][1].

Effectively and efficiently supporting crowd-enabled databases via NoSQL paradigms

2013

In this paper we provide an overview of the Hints From the Crowd (HFC) project, whose main goal is to build a NoSQL database system for large collections of product reviews; the database is queried by expressing a natural language sentence; the result is a list of products ranked based on the relevance of reviews w.r.t. the natural language sentence. The best ranked products in the result list can be seen as the best hints for the user based on crowd opinions (the reviews). The HFC prototype has been developed as a web application, independent of the particular application domain of the collected product reviews. Queries are performed by evaluating a text-based ranking metric for sets of re…
