Fuzzy ontologies and fuzzy integrals Bobillo F., Straccia U. Fuzzy ontologies extend classical ontologies to allow the representation of imprecise and vague knowledge. Although a relatively important amount of work has been carried out in the last years and they have been successfully used in several applications, several notions from fuzzy logic, such as fuzzy integrals, have not been considered yet in fuzzy ontologies. In this work, we show how to support fuzzy integrals in fuzzy ontologies. As a theoretical formalism, we provide the syntax and semantics of a fuzzy Description Logic with fuzzy integrals. We also provide a reasoning algorithm for a family of fuzzy integrals and show how to encode them into the language Fuzzy OWL 2.Source: 11th International Conference on Intelligent Systems Design and Applications, ISDA-11, pp. 1311–1316, Cordoba, Spain, 22-24 November 2011 DOI: 10.1109/isda.2011.6121841 Metrics:

Some issues on object-oriented re-engineering Signore O., Loffredo M. Software re-engineering and object orientation are two areas of growing interest in the last years. However, while many researchers have focused their interest in the object-oriented design methodologies, a little attention has been paid to the re-engineering towards an object-oriented environment. In this paper, after a brief discussion of the re-engineering issues, we examine the motivations towards object-oriented re-engineering (extendibility, robustness and reusability of the code) and the related problems, related to the difficulty of moving from a process-based to an object oriented perspective. Finally, we describe a general framework for the implementation of an object-oriented re-engineering tool.Source: ERCIM Workshop on Methods and Tools for Software Reuse, pp. 243–265, Heraklion, Crete, Greece, 29-30/10/1992

Un browser grafico sul sistema di classificazione ICONCLASS Signore O., Bartoli R., Fresta G., Loffredo M. La ricchezza delle relazioni esistenti tra i vari tipi di informazioni e la varietà degli interessi culturali degli utenti potenziali delle applicazioni nel settore dei beni culturali rendono la realizzazione di applicazioni ipermediali in questo settore una sfida di estremo interesse. L'enfasi sulle "autostrade dell'informazione" accresce l'impazienza e le aspettative degli studiosi. Tuttavia, l'entusiasmo per queste nuove tecnologie porta spesso a trascurare l'importanza di approcci più tradizionali e maturi, spesso scartati a priori perchè ritenuti "superati". In questo lavoro descriviamo il modo in cui sono stati utilizzati strumenti "vecchi", come le schede di catalogo, le liste di autorità e i thesauri, per realizzare lo strato cognitivo di un ipermedia in un progetto il cui obiettivo è lo sviluppo di una interfaccia uniforme verso le banche dati del Catalogo Nazionale dei Beni Culturali.Source: Bollettino d'informazioni - Centro di elaborazione automatica di dati e documenti storico-artistici 6 (1996): 19–28.
Parallelising the Mean Value Analysis algorithm Gennaro C., King P. J. B. The Mean Value Analysis (MVA) algorithm is one of the most popular for evaluating the performance of separable (or product form) queueing networks. Although its complexity is modest when jobs are indistinguishable, the introduction of different customer classes rapidly increases its computational cost. The problems of parallelising the algorithm while retaining its conceptual simplicity are examined. In particular, a parallel implementation of MVA on a distributed memory machine is developed using the MPI library for communication.Source: Transactions of the Society for Computer Simulation 16 (1999): 16–22. doi:10.1177/003754979907200304 DOI: 10.1177/003754979907200304 Metrics:

Digital Libraries over the Grid: Heaven or Hell?. Castelli D., Ioannidis Y. The last decade has seen unprecedented advances in network and distributedsystem technologies, which have opened up the way for the construction of globalscale systems based on completely new conceptions of computation and sharing of resources. The dream of integrating unlimited levels of processing power, unlimited amounts of information, and an unlimited variety of services, and o.ering the entire package in a reliable and seamless fashion to widely distributed users is quickly becoming reality. As Digital Libraries move towards more usercentric, pro-active, collaborative functionality and application diversity, they should be among the first to take advantage of such environments. The long-term vision of the field for creating Dynamic Universal Knowledge Environments calls for intensive computation and processing of very large amounts of information, hence, the needs for the appropriate distributed architecture are pressing.Source: ECDL 2005 - 9th European Conference on Digital Libraries (Vienna, Austria, 18-23 September 2005), pp. 477–478, Vienna, 18-23 September 2005
ENGAGED - Roadmap templates to support the cluster members in the assembly of raw roadmaps Braun A., Chessa S., Fullaondo Zabala A. The deliverable D4.1 - Roadmap templates to support the cluster members in the assembly of raw roadmaps is the first deliverable of WP4. The purpose of this document is to describe the procedure and provide supporting documents that will be used in creating the ENGAGED roadmaps as final results of the work package. The document first gives an overview of the rationale in deciding on the structure of the ENGAGED roadmap, using best practices by third party sources. In the following the roadmap template is described in detail. The next part summarises the Action Plans of the different Action Groups within EIP AHA. The input of those to the ENGAGED roadmap is discussed in detail and potential topics for the ENGAGED workshops are suggested. The next part of the document outlines templates for both workshop agenda and minutes that are specifically tailored to simplify the collection of the inputs relevant to the future roadmaps. Help is provided to the minute takers on filling out the templates, by giving detailed examples on all relevant parts and sections. The document concludes with a résumé and two annexes providing two blank templates for structural roadmap and workshop summary, respectively.Source: Project report, ENGAGED, Deliverable D4.1, 2013 Project(s): ENGAGED
Visual media for Cultural Heritage: an opportunity for assessing, finding limitations and enhancing technologies Scopigno R. Digital technologies are now mature for producing high quality digital replicas of Cultural Heritage (CH) artifacts. The research results produced in the last two decades have shown an impressive evolution and consolidation of the technologies for acquiring high-quality digital 3D models, encompassing both geometry and color (or, better, surface reflectance properties); technologies for the interactive visualisation of complex models and the integration of different media have been also an important subject of research. In this talk, I will present the more recent progresses, focusing on practical solutions which aim at a major impact in real applications. The talk will also try to give a glance into the near future, demonstrating how geometry processing and visualization could become a major instrument in the study and dissemination of our cultural heritage.Source: CESCG 2014 - 18th Central European Seminar on Computer Graphics, pp. 5–5, Smolenice, Slovakia, 25-27 May 2014
Editing Wikipedia Content by Screen Reader: Easier Interaction with ARIA Buzzi M., Leporini B. Purpose. This study aims to improve Wikipedia usability for the blind and promote the application of standards relating to Web accessibility and usability. Method. First, accessibility and usability of Wikipedia home, search result and edit pages are analysed using the JAWS screen reader; next, suggestions for improving interaction are proposed and a new Wikipedia editing interface built. Most of the improvements were obtained using the Accessible Rich Internet Applications (WAI-ARIA) suite, developed by the World Wide Web Consortium (W3C) within the framework of the Web Accessibility Initiative (WAI). Last, a scenario of use compares interaction of blind people with the original and the modified interfaces. Results. Our study highlights that although all contents are accessible via screen reader, usability issues exist due to the user's difficulties when interacting with the interface. The scenario of use shows how building an editing interface with the W3C WAI-ARIA suite eliminates many obstacles that can prevent blind users from actively contributing to Wikipedia. Conclusion. The modified Wikipedia editing page is simpler to use via a screen reader than the original one because ARIA ensures a page overview, rapid navigation, and total control of what is happening in the interface.Source: Disability and rehabilitation.

Oil spills detection through a marine environment monitoring system Moroni D., Pieri G., Salvetti O., Tampucci M. The ability to detect and monitor oil spills at sea is becoming more and more important due to the high demand of oil based products and to the increase in maritime traffic density. Remote sensing frameworks have been proved to yield accurate results in the case of major events; nonetheless also medium and micro oil spills are of their own importance, especially in protected areas that deserve special attention. In this paper, we propose a monitoring framework based on the collection of in-situ observations and on their integration with remote sensing in order to fill out existing observational gaps. A risk assessment model is included for providing environmental decision support and for generating alerts in case of potentially dangerous situations. Field operational tests in an area of great environmental interest demonstrate the technical validity of the approach.Source: IBIMET 2014 - Fifth International Symposium Monitoring of Mediterranean Coastal Areas: problems and measurement techniques, pp. 440–448, Livorno, Italy, 17-19 June 2014
Thesaurus: un database per il patrimonio culturale sommerso La Monica D., Costa S., Pace G., Martinelli M., Salvetti O., Tampucci M., Righi M. Thesaurus Project aims at promoting the knowledge of the underwater cultural heritage, ancient and modern, through the application of several typologies of tools: underwater autonomous vehicles, which will be able to explore the sea bottom in teams communicating with each other; a database, which will be useful to store and manage all the information referring to archaeological or historical objects, shipwrecks and sites. This paper aims to explain the logic structure of the database indicating the particular needs of the research, the different typologies of items which have to be managed (archaeological and historical objects; ancient, medieval or modern shipwrecks; underwater sites; written or figurative sources, etc.), the relation with other similar databases and projects. The main task of this part of Thesaurus is to plan and organize an IT system, which will allow archaeologists to describe information in detail, in order to make an efficient managing and retrieving data system available.Source: Archeologia e calcolatori 25 (2014): 51–69.
