Similarity estimation module for OWSCIS
2008
Semantic interoperability based on ontologies is nowadays becoming a great challenge. We propose an architecture for semantic-based cooperation called OWSCIS (Ontology and Web Service based Cooperation of Information Sources). It allows to map various information sources using ontologies and to answer users' queries over the cooperation. In this paper we focus on the similarity estimation service of the OWSCIS Architecture which allows to discover mappings between different ontologies. It relies on various mappings methods which are combined and refined to semi-automatically generate mappings between a local and a reference ontologies.
Mobile agents and grid computing
2004
Publisher Summary This chapter describes mobile agents as an effective solution for grid service provision. A short overview is first introduced on the grid paradigm and the most known research activities in the field. Then, mobile agents are discussed and a comparison with the remote procedure call (RPC) method is made as far as the most effective solution to minimize network overload and fault occurrences is concerned. The common feature of all grid architectures is a coordinated and controlled resource sharing between the members of a dynamic multi-institutional virtual community. Community members agree on a set of sharing rules and permissions, by which resources to be shared and membe…
A multiple layered functional data model to support multiple representations and interoperability of GIS
2001
This paper presents a multi-layered functional data model to support multiple representation and information sharing among distributed spatial information systems. The key idea is that a geographical space (foe example an urban space) can be viewed as a set of abstract spatial functionalities on which different application classes can be derived to manipulate objects of the same geographical space and share the same abstract generic functionalities. The object classes define multiple views or representations of a domain. For example in urban management, transportation systems, water supply and sewage systems applications can share generic network functionalities defined by graph treversal o…
Accessibility on the web: planning and conformance
2021
In order to give everyone the chance to access, enjoy, create and share content on the web, it is necessary to design “interoperable” interaction systems, i.e., always reliable both in different contexts of use and in the presence of different input modes. For this purpose, UX/UI designers need to acquire specific skills in the field of web standards and in writing HTML, CSS, and Javascript languages, which are fundamental for the design of accessible web components.
Predictions in Resilient Hybrid AC/DC Grids Leveraged by an Interoperable and Secure ICT Platform
2022
Power systems are undergoing a significant change and the main elements to address the new challenges is the new key-role played by the distribution grid and its transformation into a smart grid. While the distribution grid has traditionally operated with alternating current (AC), nowadays most devices operate with DC internally, and most distributed renewable resources generate power in DC. Furthermore, storage components, such as batteries and supercapacitors, have a DC character. DC seems to be the one of the most promising candidates to avoid stranded investments and to guarantee incredible saving for the community in Europe, making the transition to a fully decarbonised energy system a…
Collective Reasoning over Shared Concepts for the Linguistic Atlas of Sicily
2013
In this chapter, collective intelligence principles are applied in the context of the Linguistic Atlas of Sicily (ALS - Atlante Linguistico Siciliano), an interdisciplinary research focusing on the study of the Italian language as it is spoken in Sicily, and its correlation with the Sicilian dialect and other regional varieties spoken in Sicily. The project has been developed over the past two decades and includes a complex information system supporting linguistic research; recently it has grown to allow research scientists to cooperate in an integrated environment to produce significant scientific advances in the field of ethnologic and sociolinguistic research. An interoperable infrastruc…
Internet of things: why we are not there yet
2014
Twenty-one years past since Weiser's vision of ubiquitous computing (UbiComp) has been written, and it is yet to be fully fulfilled despite of almost all the needed technologies already available. Still, the widespread interest in UbiComp and the results in some of its fields pose a question: why we are not there yet? It seems we miss the 'octopus' head. In this paper, we will try to depict the reasons why we are not there yet, from three different points of view: interaction media, device integration and applications.
An Ontology Architecture for Standards Integration and Conformance in Manufacturing
2007
Standards reflect consensus on the semantics of terms. When used to communicate, whether between people or software systems, standards ensure the communication is correct. Different standards have different semantics for the same terms and express common concepts using different terms and in different ways. Communication between software systems based on different standards is sometimes difficult to achieve. Standards integration concerns the explicit representation of the overlapping sets of concepts in standards and the differences in their semantics to ensure that these standards are used consistently together. This in turn enables software that is based on integrated standards to intero…
TIME : A Translator Compiler for CIS
2002
To build a Cooperative Information System, a first step is to collect schemas of each local database. All the schemas exported from databases are translated and integrated into a cooperative schema, which is used by the final user to query the cooperation “transparently”. In this article, we focus on the definition of tools that are used to build and manage cooperative information systems. These tools enable the automatic or semi-automatic generation of specific translators. The first step of our methodology is a knowledge acquisition step that allows for the data model description of each local database. The second step is to compare all these descriptions in order to organize the correspo…
A Rule-Based System for Hardware Configuration and Programming of IoT Devices
2019
Simplifying programming, deployment, and configuration of heterogeneous networked IoT devices requires networking, hardware, representation of knowledge and concepts, design and programming skills. In fact, IoT applications are mostly built by adopting different existing paradigms and technologies on a case-by-case basis. As a result, programming tools hinder adaptability and interoperability of applications with their rigidity. In this paper, we propose a rule-based system that configures and programs IoT devices automatically. The rule base holds formal specifications about hardware platforms, networking protocols, physical world concepts, and applications. Provided with a high-level appl…
