Title: Federated Data Stores using Semantic Web Technology
Abstract: Big Data is a popular buzzword today, underscored by the March 29th 2012 White House announcement of the federal Big Data Research and Development Initiative. This talk will provide a gentle introduction to one aspect of big data, which is the use of semantic technology languages. These languages provide greater expressivity than with traditional databases, and offer the ability to query data distributed among multiple data stores, making it easier to dynamically integrate disparate systems. Some examples uses of these capabilities will be given.
Speaker Bio: Steven R. Ray is a Distinguished Research Fellow at Carnegie Mellon Silicon Valley, where he researches information interoperability and standards in application domains including disaster management, smart electrical grid, electronic business, supply chains, and manufacturing. A common theme of his work is the use of ontologies and formal representations to ensure unambiguous definitions of terms and relations. He has a twenty-seven year track record of initiating and leading technical R&D projects at the National Institute of Standards and Technology in Gaithersburg, Maryland. Until 2009, he was responsible for the management of a $10-13M division of 60 staff and visiting researchers dedicated to the solution of national problems related to measurements and standards supporting systems interoperation in the manufacturing sector. Dr. Ray’s current activities include work in new research programs at Carnegie Mellon Silicon Valley in disaster management and in smart grid interoperability, chairmanship (Emeritus) of the Ontology Summit and the OASIS Quantities and Units of Measure Ontology Standard (QUOMOS) TC, as well as consulting support for local technology companies. He is a member of ASME and SME. He received his Ph.D. in Mechanical and Aerospace Engineering in 1981 from Princeton University, and his Bachelor's degree in Physics from the University of Bristol, England.
