[Solomonov Seminar] 209. Solomonov seminar

[Marko Grobelnik]

V ponedeljek 25. maja bo ob 11:30h v Oranzni predavalnici IJS
(drugo nadstropje glavne zgradbe), 209. Solomonov seminar.
Posnetki preteklih seminarjev so na http://videolectures.net/solomon/

Predavala bo gostja Renee J. Miller iz Univerze v Torontu -
tema bo pregledno predavanje o povezovanju podatkovnih shem.
Ta temo je v zadnjih letih precej pomembna v smislu integracije
raznih podatkovnih baz.

Renee J. Miller Uni. Toronto:
   Schema Mapping:  Past, Present and Future

We present a retrospective on key contributions of the Clio project, a joint project between the IBM Almaden Research Center and the 
University of Toronto begun in 1999.  Clio's goal was to radically simplify information integration, by providing tools that help in 
automating and managing one challenging piece of that problem: the conversion of data between representations.  Clio pioneered the 
use of schema mappings, specifications that describe the relationship between data in two heterogeneous schemas.  From this 
high-level, non-procedural representation, it can automatically generate either a view, to reformulate queries against one schema 
into queries on another for federated data integration, or code, to transform data from one representation to the other for data 
exchange.  We then consider how the foundations laid by Clio have been used and extended in Iliads, a system for ontology alignment 
developed in collaboration with the University of Maryland.  Time permitting, we will briefly describe how integrated data is 
managed and queried today, including techniques for querying potentially inconsistent data developed in our ConQuer system.  We 
conclude with a vision for the future of data integration research.Renee J. Miller is a professor of computer science and the Bell Canada Chair of Information Systems at the University of Toronto. 
She received the US Presidential Early Career Award for Scientists and Engineers (PECASE), the highest honor bestowed by the United 
States government on outstanding scientists and engineers beginning their careers. She received an NSF CAREER Award, the Premier's 
Research Excellence Award, and an IBM Faculty Award.  Her research interests are in the efficient, effective use of large volumes of 
complex, heterogeneous data.  This interest spans data integration and exchange, inconsistent and uncertain data management, and 
data curation and cleaning.  She serves on the Board of Trustees of the
VLDB Endowment and served as PC co-chair of VLDB in 2004.  She received her PhD in Computer Science from the University of 
Wisconsin, Madison and bachelor's degrees in Mathematics and Cognitive Science from MIT.
