Abdullah Uz Tansel
Professor at Baruch College-CUNY
Abdullah Uz Tansel is professor of Computer Information Systems at the Zicklin School of Business at Baruch College and Computer Science PhD program at the Graduate Center. His research interests are database management systems, temporal databases, data mining, and semantic web. Dr. Tansel published many articles in the conferences and journals of ACM and IEEE. Dr. Tansel has a pending patent application on semantic web. Currently, he is researching temporality in RDF and OWL, which are semantic web languages. Dr. Tansel served in program committees of many conferences and headed the editorial board that published the first book on temporal databases in 1993. He is also one the editors of the forth coming book titled Recommendation and Search in Social Networks to be published by Springer.

Throughout the history, exchange of trusted information among people played an essential role in every aspect of their lives: socially, economically and politically. Blockchain is an innovation in database technology for keeping temper proof (trusted) data in a permanent, immutable, decentralized, global, and trustless ledger. It combines distributed computing, databases, networks and cryptogra...

Big data is of interest to many applications and it naturally involves time. The presentation explores time ontology and addresses the subtle issues in managing temporal data and temporal knowledge: comparing database states at two different time points, capturing the periods for concurrent events and accessing to times beyond these periods, sequential semantics, handling multi-valued attribute...
In the past manipulating temporal data was rather ad hoc and in the form of simple solutions. Today organizations strongly feel the need to support temporal data in a coherent way. Consequently, there is an increasing interest in temporal data and major database vendors recently provide tools for storing and manipulating temporal data. However, these tools are far from being complete in address...
