Mathieu D'Aquin — Semantic Web, Linked Data and Education: A Perfect Fit?

The Semantic Web has been for a long time considered a pure research area, concerned with the way to formally express and share knowledge in reusable forms. With the emergence of Linked Data, it is now considered from a more practical perspective, with many concrete applications in many different domains, as well as new technical issues related to the scale, distribution and heterogeneity of the data now available online. The Open University has pioneered the use of Linked Data in the higher education sector, not only through providing the first university-wide deployment of Linked Data to expose its public information, but also through the large variety of applications developed that exploit these data. Besides providing a valuable resource for learners and teachers, this experience has made emerge new challenges for research in the Semantic Web area, related to the discoverability of (educational) resources through Linked Data, the analysis and interpretation of information from connected sources, or the way following links into Web knowledge can lead to new research methodologies and new research questions. By investigating such challenges, we show how the realisation of the Semantic Web could provide the perfect technological solution to one of the most fundamental goals of education: sharing knowledge globally.

Mathieu d’Aquin is a Research Fellow at the Knowledge Media Institute of the The Open University. He obtained is PhD in 2005 from the University of Nancy, France, where he worked on concrete applications of semantic technologies in the medical domain. He is now leading research around concrete solutions for the realization of applications producing and consuming linked data, as well as on more fundamental aspects of the Semantic Web (ontology modularization, evolution and matching, Semantic Web reasoning and analysis). He was a key member of the EU NeOn and the director of the LUCERO project responsible for setting up the Open University’s Linked Data platform. He is now involved in several research and development projects, related to the exploitation of Linked Data and Semantic Web technologies for education and research. Mathieu d’Aquin was Vice-Chair for the 2010 conference on Web Intelligence, Chair of the Ontology Track at the Extended Semantic Web Conference 2011 and senior programme committee member for the International Semantic Web Conference in 2011. Mathieu d’Aquin was recognised in 2011 as one of the 10 most promising young researchers in artificial intelligence, through the “AI 10 to watch” award from the prestigious magazine IEEE Intelligent Systems, and has won numerous other awards especially related to innovative applications of semantic technologies. He is also, since 2012, the director of the SSSW summer school on ontology engineering and the Semantic Web, one of the key educational events in the Semantic Web area.

Alessio Malizia — Sentiment Analysis and Opinion Mining: The New Semantics of Users' Perception

This talk presents a review of theories and frameworks for building intelligent systems for detecting users’ perception and opinions through the use of Internet. Users’ perception is crucial for detecting the possible success or failure of a company in the Web 2.0 era more than in the past. For this reason we propose in this speech a series of approaches for building intelligent systems that are able to detect users’ opinion about a topic in Internet (Social Networks, Recommendation Systems, etc.) We demonstrate how such systems could provide stakeholders with knowledge about users’ perception for decision-making, and knowledge discovery applications, by presenting two use cases.

Alessio Malizia is Senior Lecturer at Dept. of Information Systems and Computing, Brunel University, Uxbridge, UK. He obtained the Master degree cum laude in Computer Science from the University of Rome "La Sapienza" (ITALY), in December 1997. From 1998 until 2007, he was a member of Pictorial Computing Lab, Computer Science Dept., University “La Sapienza” of Rome. From 1999 to 2002 he was software engineer for Rome IBM Tivoli Lab, Silicon Graphics and Reply group. During the Summer 2003, he had a three months summer internship at the XEROX PARC (Palo Alto Research Center, Palo Alto, CA, USA) in the ISTL (Information Science and Technology) Lab working in Human Document Interaction. In 2003-2004 he had a Visiting researcher contract at the XEROX PARC (Palo Alto Research Center, Palo Alto, CA, USA) in the ISTL (Information Science and Technology) Lab working in Human Document Interaction. In March 2003-Feb 2007, he is a research fellow at the Department of Computer Science of the University of Rome "La Sapienza". From March 2007 to Sept 2012 he had different positions at Computer Science Dept. of University Carlos III in Madrid, Spain as visiting professor, lecturer and tenure-track Associate Professor. In the past his research activities focused on theory and algorithms for pattern recognition, machine learning and visualization. Today he is working on Human Computer Interaction and Information Retrieval, Pervasive Computing and Social Networking.
