Prof. Dr. Christian Bizer
University of Mannheim, Germany
Christian Bizer explores technical and empirical questions concerning the development of global, decentralized information environments. He has initialized the W3C Linking Open Data community effort which is interlinking large numbers of data sources on the Web. He co-founded the DBpedia project which derives a comprehensive knowledge base from Wikipedia. He also initialized the WebDataCommons project which monitors the deployment of RDFa, Microdata, and Microformat data on the Web by analyzing large Web crawls. Further results of his work include the Named Graphs data model, the D2RQ mapping language, the Silk linking framework, and the Berlin SPARQL Benchmark. Christian Bizer holds an appointment as full professor at the University of Mannheim. Before moving to Mannheim, he headed the Web-based Systems Group at Freie Universität Berlin.

Prof. Emanuele Della Valle
DEIB – Politecnico di Milano, Italy
Emanuele Della Valle is assistant professor at the Department of Electronics, Information and Bioengineering of the Politecnico di Milano since 2008. He performs researches that are justified and guided by business needs in smart city, social media analytics, and, previously, in health care and life science. In more than a decade of research, his research interests covered Semantic Web, Big Data, Stream Management Systems, Search Engines, Rank-aware Databases and Service Oriented Architectures. The stream reasoning concept (an approach to master the velocity and variety dimensions of Big Data) and its embodiment in the Continuous SPARQL query language are his major research contributions. He co-authored the first book in Italian about Semantic Web (2008), a book on Web Information Retrieval (2013), 15 journal articles and more than 50 research papers in major conferences. His h-index is 20. From 2001 to 2008, he worked in CEFRIEL. Between 2001 and 2004, he worked in strategic consultancy IT projects of CEFRIEL in eBusiness, eGovernment and eHealth. In 2003, he started the Semantic Web Practice of CEFRIEL that he coordinated until 2008. He was Aggregated Professor of Knowledge Engineerig at Università dell’Insubria from 2006 and 2010.

Title of presentation: Smart Data & Privacy by Design. Win-to-win
business models on competitive digital market [abstract]
Christian Bizer: Evolving the Web into a Global Dataspace – Advances and Applications
Motivated by Google, Yahoo!, Microsoft, and Facebook, hundreds of thousands of websites have started to annotate structured data within their pages using markup formats such as Microdata, RDFa, and Microformats. In parallel, the adoption of Linked Data technologies by government agencies, libraries, and scientific institutions has risen considerably. In his talk, Christian Bizer will give an overview of the content profile of the resulting Web of Data. He will showcase applications that exploit the Web of Data and will discuss the challenges of integrating and cleansing data from thousands of independent Web data sources.
Emanuele Della Valle: Listening to the pulse of our cities fusing Social Media Streams and Call Data Records
The digital reflection of our cities is sharpening and it is tracking their evolution with a decreasing delay. This happens thanks to the pervasive deployment of sensors, the wide adoption of smart phones, the usage of (location-based) social networks and the availability of datasets about urban environment. So while data becomes every day more abundant, decision makers face the challenge to increase their capability to create value out of the analysis of this data. This key note presents how advance visual analytics, ontology base data access and information flow processing methods can help in making sense of Social Media Streams and Call Data Records from Mobile Network Operators during city scale events. Real-world deployments demonstrate the ability of those methods to advance our ability to feel the pulse of our cities in order to deliver innovative services.
Harald Sack: The Journey is the Reward – Towards New Paradigms in Web Search
Without search engines the information content of the World Wide Web would remain largely closed for the ordinary user. Current web search engines work well as long as the user knows what she is looking for. The situation becomes problematic, if the user has insufficient expertise or prior knowledge to formulate the search query. Often a sequence of search requests is necessary to answer the user’s information needs, whenever knowledge has to be accumulated first to determine the next search query. On the other hand, retrieval systems for traditional archives face the problem that there is possibly not always a result for an arbitrary search query, simply because of the limited number of documents available. Semantic search systems (try to) determine the meaning of the content of the archived documents first and thus in principle are able to overcome problems of traditional keyword-based search engines concerning the processing of natural language. Moreover, content-based relationships among the documents can be used to filter, navigate, and explore the archive. Content-based ‚intelligent’ recommendations help to open up the archive and to discover new paths across the search space.
