BlueBRIDGE organized a webinar on 28 June 2017, 11.10am CEST, with the aim to highlight the importance of a semantic integration of data, the current approaches for integration and the main case studies of marine data coming from the BlueBRIDGE project. It showcased a process to construct semantic warehouse of marine data and how it can be exploited. 

This webinar was of particular interest for data Scientists working with marine data, engineers working on semantic data integration solutions and researchers interested in semantic data integration approaches.

Webinar Description

Every day we produce huge amounts of data of various types and purposes, however these data are not integrated. Data integration aims at combining data residing in different sources and providing users with a unified view of these data. The unified view enables answering queries and discovering insights which are not possible to obtain from individual sources. Data integration is significant in a variety of situations and of paramount importance for e-science  especially for large-scale scientific questions such as global warming, invasive species spread, and resource depletion.
This webinar described the motivation for semantic integration of data, its difficulties, the related requirements and tasks, the main approaches for integration, and then it focused on case studies of marine data coming from the ongoing BlueBRIDGE project as well as from previous projects in the same area (the completed EU research infrastructure project iMarine). A process for constructing semantic warehouses of marine data was introduced, a process that comprises various steps including ontology-engineering, schema mapping, entity matching, provenance management, and quality testing.  Finally, the webinar discussed the exploitation of such semantic warehouses, as well as future steps and open challenges.

Speaker profile

Yannis Tzitzikas is currently Associate Professor of Information Systems in the Computer Science Dep. at University of Crete (Greece) and Affiliated Researcher of the Information Systems Laboratory at FORTH-ICS (Greece). Before joining UofCrete and FORTH-ICS he was postdoctoral fellow at the University of Namur (Belgium) and ERCIM postdoctoral fellow at ISTI-CNR (Pisa, Italy) and at VTT Technical Research Centre of Finland. He conducted his undergraduate and graduate studies (MSc, PhD) in the Computer Science Department at the University of Crete. In parallel, he was a member of the Information Systems Lab of FORTH-ICS for about 8 years, where he conducted basic and applied research around semantic network-based information systems within several EU-founded research projects. His research interests fall in the intersection of the following areas: Information Systems, Information Indexing and Retrieval, Conceptual Modeling, Knowledge Representation and Reasoning, and Collaborative Distributed Applications. Currently his research focuses on: exploratory searching (principles, techniques, applications), semantic data management (comparison functions, knowledge evolution, indexes, visualization, integration), and methodologies and technologies for building advanced information systems for digital preservation.
The results of his research (mainly conducted with students) have been published in more than 90 papers in refereed international conferences and journals, and he has received two best paper awards (at CIA’2003 and ISWC’07). He has supervised more than 20 Diploma and 15 MSc theses, and he actively participates in EU projects having achieved more that 700K Euros funding the last 4 years. Finally he regularly participates to the scientific committees of several international conferences and journals.
