Big Data, Semantic Web, and EarthCube

One of the key challenges of dealing with Big Data is that of semantic variety (or heterogeneity), i.e. the fact that the meaning (and, thus, how to make intelligent use) of the data varies widely due to differing viewpoints, conceptualizations, and contexts underlying the data. Semantic Web technologies have been designed for more than a decade now to deal with semantic heterogeneity, and they thus provide foundational methods for tackling this key Big Data issue. We present central challenges and some recent advances in this context, and discuss the potential of ontology design patterns for tackling semantic heterogeneity, with examples from the geosciences.

About Pascal Hitzler

Pascal Hitzler is Associate Professor at the Kno.e.sis Center for Knowledge-enabled Computing, which is an Ohio Center of Excellence at Wright State University in Dayton, Ohio, U.S.A. From 2004 to 2009, he was Akademischer Rat at the Institute for Applied Informatics and Formal Description Methods (AIFB) at the University of Karlsruhe in Germany, and from 2001 to 2004 he was postdoctoral researcher at the Artificial Intelligence institute at TU Dresden in Germany. In 2001 he obtained a PhD in Mathematics from the National University of Ireland, University College Cork, and in 1998 a Diplom (Master equivalent) in Mathematics from the University of Tuebingen in Germany. His research record lists over 250 publications in such diverse areas as semantic web, neural-symbolic integration, knowledge representation and reasoning, machine learning, denotational semantics, and set-theoretic topology. He is Editor-in-chief of the Semantic Web journal by IOS Press and of the IOS Press book series Studies on the Semantic Web. He is co-author of the W3C Recommendation OWL 2 Primer, of the first German introductory textbook to the Semantic Web published by Springer Verlag, and of the book Foundations of Semantic Web Technologies by CRC Press, 2010 which was named as one out of seven Outstanding Academic Titles 2010 in Information and Computer Science by the American Library Association’s Choice Magazine, and is currently being translated into Chinese. He is on the editorial board of several journals and book series and on the steering committee of conference series like RR and ICCS, and he frequently acts as conference chair in various functions, including e.g. General Chair (RR2012), Program Chair (ODBASE2011, RR2010), Track Chair (ESWC2013, ESWC20111, ISWC2010), Workshop Chair (K-Cap2013), Sponsor Chair (ISWC2013, RR2009, ESWC2009).
