ODINet - Online Data Integration Network

Along with the expansion of Open Data and according to the latest EU directives for open access, the attention of public administration, research bodies and business is on web publishing of data in open format. However, a specialized search engine on the datasets, with similar role to that of Google for web pages, is not yet widespread. This article presents the Online Data Integration Network (ODINet) project, which aims to define a new technological framework for access to and online dissemination of structured and heterogeneous data through innovative methods of cataloging, searching and display of data on the web. In this article, we focus on the semantic component of our platform, emphasizing how we built and used ontologies. We further describe the Social Network Analysis (SNA) techniques we exploited to analyze it and to retrieve the required information. The testing phase of the project, that is still in progress, has already demonstrated the validity of the ODINet approach

ODINet un framework innovativo per l\u27accesso e la diffusione on-line di dati strutturati ed eterogenei

ODINet is a research and development project, approved as part of the Regional Operational Programme through the European Regional Development Fund 2007-2013. The project involves the construction of a semantic search engine prototype able to catalog the data in a ontological graph, to extract the most relevant information depending on user requests and return them in a highly usable way. The application domain concerns the social, economic and health, in order to cover most of the data held by public bodies in the national context. The focus of this report is in the first place the description of the semantic components of the platform, emphasizing how the ontologies have been used to build an index in the form of graph. We also present a description of our semantic searches and finally an analysis of the results obtained in the final stage of the ODINEt prototype testing
