dr. Sebastian Ryszard Kruk is the co-founder and CEO of KnowledgeHives.com, a Web 3.0 startup. Previously, he was a PhD student, researcher (Semantic Infrastructure Lab at e-Learning Cluster in DERI NUI Galway), and project manager (Corrib.org) affiliated with DERI, National University of Ireland, Galway and the Gdansk University of Technology (GUT). His main areas of interest cover Semantic Web and social networking technologies, digital libraries, knowledge management, information retrieval, security and distributed computing.
In 2002, together with prof. Henryk Krawczyk he came up with an idea of the semantic digital library which was implemented first at GUT as the Elvis-DL project. In 2004, together with prof. Stefan Decker he transformed Elvis-DL into an open source project called JeromeDL, which was established as a joint initiative between DERI NUI Galway and GUT. In 2006 he delivered JOnto component, a unified API for
accessing different knowledge organization systems; recently published OpenVocabulary service builds on the ideas researched in the JOnto project. Together with Adam Gzella, he set up notitio.us - a social semantic information sources discovery and sharing service. His company has released the digi.me service, which grew out of ideas researched in the notitio.us.
In 2008, together with Bill McDaniel he edited a book, and contributed to most of the chapters, on Semantic Digital Libraries (published by Springer). He was invited to give five tutorials (at ICSD, JCDL, ESWC,WWW) on Semantic Digital Libraries and one on tutorials on Web 3.0 (Autumn Meetings of PTI). In 2007, he organized the Irish Digital Libraries Summit and co-organized a Workshop on Web Archiving and NKOS
Workshop (at ESWC 2006).
He contributes to the Open Source community. He received the best paper award for the paper "Semantically Enhanced Search Services in Digital Libraries" at the International Conference on Internet and Web Applications and Services, 2006.
