To perform this recommen- dation, it draws upon a large collection of distributed, linked-data and Web 2.0 data sources it queries live, and provides a clear, simple user in- terface that regular citizens can easily use to situate useful, but formerly inaccessible, information within the context of their daily activities.

Many ontologies have been proposed over the years in different domains, thus producing a semantic heterogeneity that is difficult to manage. Var- ious automated ontology mapping techniques and tools have been developed to facilitate the bridging and inte- gration of

In the present paper we report on the work done inside a project sponsored by ASI (the Italian Space Agency) aimed at building an intelligent multi-agent system for the control and supervision of the SPIDER Manipulation System with some form of interaction with the human operator. In particular, we will ...

Current solutions facilitating end user access to Linked Data are either thought the use of data-mapping approaches, which allow configureable interfaces to be quickly deployed over preselected aggregations of Linked Data, or enable users themselves to browse the Web of Data through the use of generic data browsers.

Besides, there are agent based formalisms which allow to study the emergency of social behavior with the creation and study of models, known as artificial societies.

Known as” open data” while these are valuable assets, much of this data remains useless because it is effectively inaccessible for citizens to access for the following reasons:(1) it is often a tedious, many step process for citizens simply to find data relevant to a query.

While reusing existing ontologies is the choice of preference, the exploitation of ontology alignments still is a required step for easing the burden of integrating heterogeneous data sets.
The development of diagnostic software is very critical in current generation automotive systems.

These data, and datasets, are normally in different datastores and of different formats. Connecting these datasets together will increase their value and help discover interesting relationships amongst them. This paper describes our experience of using Linked Data to inter-operate these different datasets, the challenges we faced, and the solutions we devised. The paper concludes with apposite design principles for using linked data to inter-operate disparate datasets.

For several years, the Semantic Web community has been developing algorithms for aligning data models (ontologies). Nevertheless, exploiting such ontology alignments for achieving data integration is still an under supported research topic. The semantics of ontology alignments, often defined over a logical framework, implies a reasoning step over huge amounts of data. This is often hard to implement and rarely scales on Web dimensions. This paper presents our approach for translating DL-like ontology alignments into graph patterns that can be used to implement ontological mediation in the form of SPARQL query rewriting and generation. This approach backs up a previous work for achieving SPARQL query rewriting where syntactical transformations of basic graph patterns are used. Supporting a rich ontology alignment language into our system is important for two reasons. Firstly the users can express rich alignments focusing on their semantic soundness; secondly more verbose correspondences of RDF patterns can be generated by the translation process providing a denotational semantics to the alignment language itself. The approach has been implemented into an open source Java API freely available to the community.

In particular, general guidelines do not take into account the fact that the tools needed for laboratory and instrumental investigations might be unavailable at a given hospital. Moreover, computer-based guideline managers must also be integrated with the Hospital Information System (HIS), and usually different DBMS are adopted by different hospitals. The GLARE (Guideline Acquisition, Representation and Execution) system addresses these issues by providing a facility for automatic resource-based adaptation of guidelines to the specific context of application, and by providing a modular architecture in which only limited and well-localised changes are needed to integrate the system with the HIS at hand.

GLARE has been built within a 7-year project with Azienda Ospedaliera San Giovanni Battista in Turin (one of the largest hospitals in Italy) and has been successfully tested on clinical guidelines in different domains, including bladder cancer, reflux esophagitis, and heart failure. GLARE is characterized by the adoption of advanced Artificial Intelligence (AI) techniques, to support medical decision making and to manage temporal knowledge.

By secure data exchange we mean that privacy and integrity are ensured when documents flow among different parties. A key issue in this scenario is how to ensure that web documents, when moving among different parties, are modified only according to the stated access control policies. To cope with such an issue, in this paper we propose a distributed infrastructure that enable subjects to verify, upon receiving a document, ...
