For more information on FLICS, please check out: http://fantasticlecturesincomputerscience.blogspot.com/ Abstract: Moore's Law holds that, every 18 months, computing power doubles. Most of the wonders of the computer age can be attributed directly to Moore's Law. Alas, its days are numbered. What then? In this talk, I will argue that the years ahead will usher in the era of the "Algorithm," a notion that might prove just as disruptive as the revolution in the physical sciences was in the last century. I will discuss why algorithms are even more powerful than customarily believed but why they will not unleash their true potential until they become full-fledged scientific tools and not just problem-solvers. ----------------------------------------------------- BIO Bernard Chazelle is Eugene Higgins Professor of Computer Science at Princeton University, where he has been on the faculty since 1986.

At the core is the problem of discovering semantics for database schemas that describe the underlying data. The semantics of a database schema can be captured by a set of semantic mappings between the schema and a conceptual model or an ontology. In this talk, I will describe our study on discovering and maintaining semantics for database schemas and using the semantics to facilitate the discovery of direct mappings between relational schemas. We developed a semi-automatic tool, MAPONTO, which takes as input a database schema, a conceptual model (CM), and a set of simple correspondences between atomic elements in the schema and the CM. It then generates a set of logical formulas that define a mapping from the schema to the CM. To deal with CM/schema changes, we proposed a round-trip engineering solution which essentially synchronizes models by keeping them consistent for maintaining semantics. We also extended MAPONTO with a semantic approach to finding schema mapping expressions. The approach leverages the semantics of schemas expressed in terms of conceptual-relational mappings. Our evaluation results show that MAPONTO is effective in discovering and maintaining semantics for schemas and it outperforms the traditio! nal mapping techniques for building complex schema mapping expressions in terms of both recall and precision. Finally, I will discuss our experience in developing the MAPONTO tool and present several conclusions. Biography: Dr. Yuan An received a PhD degree in Computer Science from the University of Toronto in 2007. He has been an assistant professor in the College of Information Science and Technology at Drexel University since that year. He has research interests in conceptual modeling, data integration, schema and ontology mapping, requirements engineering, and the semantic web. Dr. An designed and developed the MAPONTO tool for creating semantic mappings between heterogeneous data representation. He is now working on several projects on healthcare informatics including designing healthcare information systems and integrating heterogeneous healthcare data. He has been publishing in ICDE, ER, CAiSE, ISWC, ODBASE, and the Journal of Data Semantics. Dr. An also has more than 10 years working experience in the Information Technology industry. As a principal developer and team leader, he designed and led the development of the management information systems for manufacturers of electro! nic products, real estate companies, financial and educational institutes in various sizes. Dr. An has a Master's degree in Computer Science from Dalhousie University, Canada. He also earned a Master's degree in Electrical Engineering from Tsinghua University, China, in 1989 and a Bachelor's degree in Electrical Engineering from the same Chinese university in 1987. Date: February 23, 2009 Time: 4:30 p.m. Location: Mendel Science Center 102 Refreshments and conversation will be shared immediately after the colloquium in MSC 159.
