The Prague Computer Science seminar series, coorganized by Department of Computer Science, presents:
Programming with Semantic Broad Data by Steffen Staab
Thursday, September 22, at 4 p.m. in room KNE:107.
The challenges of Big Data are frequently explained by dealing with Volume, Velocity, Variety and Veracity. The large variety of data in organizations results from accessing different information systems with heterogeneous schemata or ontologies. In this talk I will present the research efforts that target the management of such broad data. They include: (i) an integrated development environment for programming with broad data, (ii) a query language that allows for typing of query results, (iii) a typed lambda-calculus based on description logics, and (iv) efficient access to data repositories via schema indices.
More about the lecturer:
Steffen studied computer science and computational linguistics in Erlangen (Germany), Philadelphia (USA) and Freiburg (Germany). Afterwards he worked as researcher at Uni. Stuttgart/Fraunhofer and Univ. Karlsruhe, before he became professor in Koblenz, Germany. Since 2015 he also holds a chair in Web and Computer Science at University of Southampton, UK. In his research career he has managed to avoid almost all good advice that he now gives to his team members. Such advise includes focusing on research (vs. company) or concentrating on only one or two research areas (vs. considering ontologies, semantic web, social web, data engineering, text mining, peer-to-peer, multimedia, HCI, services, software modelling and programming and some more). Though, actually, improving how we understand and use text and data is a good common denominator for a lot of Steffen's professional activities.
