  15. The Canadian Potato Genomics Project ATLANTIC CANADA • 46% of national • potato production • $1 Billion/year • Home of McCain • Foods Ltd. • $5.5 billion/year • Potato Research • Center of AAFC • Solanum Genomics • International Inc.

  16. The Canadian Potato Genomics Project Research Areas • Bioinformatic Analysis • Access to resources via CBR membership/node status • Raw sequence processing and analysis by Fredericton • bioinformatics group • (Vector trimming, base calling, clustering, contig assembly, BLAST, annotations) • Relational database management system of CPGP to • link NRC (sequencing), CBR and researchers • In silico assignment of gene function • Microarray data

  17. The Canadian Potato Genomics Project Research Areas • Bioinformatic Research To Suit Project Needs (UNB): • Autonomous agent development to automatically update • sequence annotations • Enhancement of bioinformatic algorithm performance • with parallel computing • Algorithm development using annotation information to • enhance sequence searching • The application of clustering and learning techniques to • the analysis of expression data

  19. Performance Evaluation of ACORN • Test-bed: Several Autonomous Servers, each serving autonomous virtual users • Virtual User - capable of creating agents - picks up a topic from a client core’s interest - migrates to other servers - potential destinations

  20. Performance Evaluation of ACORN

  21. Why learning objects? • COST: 1000s of colleges have common course topics • large numbers of courses are going online • World does not need 1000s of similar learning topics • World needs only about a dozen • Expensive to develop so sharing is essential • (From Downes, 2000) Design courses as a collection of learning objects NOT HTML

  22. What is METADATA? data about data Metadata standards are agreed-on criteria for describing data to support interoperability Example: January 31, 2001 31 janvier 2001 2001-01-31 01-31-2000 31012000

  23. Metadata and RDF implementation * XML * Resource Description Framework (RDF) = structure Metadata = semantics & resources

  24. Conclusion • Parallel/Distributed Processing • Multi-Agent Systems (Distributed Artificial Intelligence) • NSERC Project, The Canadian Potato Genomics Project • eLearning (eduSorceCanada Project) • Automated and manually-driven user profile generation and update
