Tope Omitola is a Senior Research Fellow with the Web and Internet Science Group at the School of Electronics and Com puter Science in the University of Southampton. His research interests include provenance for Linked Data, semantic social data mining and text extraction, semantic search and informa tion discovery, and semantic dataset discovery and ranking. He was educated at King’s College London and at Jesus College Cambridge. He has worked in a variety of programming and software engineering positions with companies such as ARM and BT Labs. He co-authored the paper “Put In Your Postcode, Out Comes the Data: A Case Study” which won the best paper award at ESWC 2010, and has published at various high-profile conferences. Dr. Omitola is a member of AAAS, ACM and IEEE.Sebastián A. Ríos is an Assistant Professor in the Industrial Engineering Department of the University of Chile, where he is also Director of the Masters in Business Engineering. He is the Director of the CEINE Business Intelligence (BI) Research Center at the University of Chile, a collaborative applied re search effort with Telefonica Chile. His interests include BI, the Semantic Web, social networks, latent semantics, process mining and business process redesign, and he has received fund ing from CONICYT and CORFO. He completed his Ph.D. in Knowledge Engineering at the University of Tokyo in 2007 after receiving the Mobukagakusho Scholarship from the Japanese Government, and has a degree in industrial engineering and IT/- data mining from the University of Chile.
