Title: Semantic Digital Libraries  (slides)

Su-Shing Chen

Professor, Dept. of Computer Information Science & Engineering, University of Florida, U.S.A.

Abstract:

Digital libraries and web services have converged. Recently the Semantic Web has proposed an ontology-based approach to both digital libraries and web services. The question remains on how to map an
existing digital library to another large ontology database. I will present new results on assigning MEDLINE citations to the GO (Gene Ontology) database by the associative naive Bayesian classifier.

Title: Knowledge Based Techniques for Retrieving Free Text Medical Reports (slides)

Wesley Chu

Professor, Dept. of Computer Science, University of California, Los Angeles, U.S.A.

Abstract:

Medical free-text queries often share the same scenario. A scenario represents a repeating task in healthcare. For example, a specific scenario is searching for treatment methods for a specific disease, where “treatment” is a term indicating the scenario. To support scenario-specific retrieval, in this talk, we present a new knowledge-based approach to address these problems. In addition, we describe a testbed system developed using the approach. Our specific implementation uses the UMLS Metathesaurus and semantic structure to extract key concepts from a free-text. The approach uses phrase-based indexing to represent similar concepts, and query expansion to improve matching query terms with the terms in the document. The system formulates the query based on the user’s input and the selected scenario template such as “disease, treatment” or “disease, diagnosis.” Thus, it is able to retrieve documents relevant to the specific scenario. Evaluating the system using the standard OSHMED corpus, our empirical results
validate the effectiveness of this new approach over the traditional text retrieval techniques.

Wesley Chu is a Professor of Computer Science and was the past chairman (1988-1991) of the Computer Science Department at the University of California, Los Angeles. He received his B.S.E. (EE) and M.S.E (EE) from the University of Michigan in 1960 and 1961. He received his Ph.D. (EE) from Stanford University in 1966.

     From 1988 to 1991, he was the Principal Investigator of ONR contract on Fault Tolerant Distributed Database Systems, and from 1989 to 1991, he was the Co-Principal (Dr. Popek, the Principal Investigator) of a DARPA contract on Very Large Distributed Information Processing Systems. From 1991 to present, he is the Co-Principal Investigator of a DARPA contract on Large Scale Filing and Data Management Environments. From 1991 to 1993, he is the principal investigator of the NSF contract on A Knowledge-Based Multimedia Medical Distributed Database System.

     From 1964 to 1966, he worked on the design of large-scale computers at IBM, Menlo Park and San Jose, California. From 1966 to 1969, he researched computer communications and distributed databases at Bell Laboratories, Holmdel, New Jersey. He joined the University of California, Los Angeles in 1969. He directs a research group at UCLA in the areas of computer communications and networking, distributed processing, and knowledge based distributed databases. He is also a consultant to government agencies and private industries. He has authored or co-authored more than 100 articles on information processing systems and has edited three textbooks: Advances in Computer Communications, (Artech House, 1st ed. 1974 and 2nd revised ed. 1977), Centralized and Distributed Database Systems (co-edited with P. P. Chen, IEEE Computer Society, 1979), and Distributed Systems, Vol. I: Distributed Processing Systems, Vol.II: Distributed Database Systems (Artech House, 1986).

     Dr. Chu is a Fellow of IEEE. He was the program co-chairman for the First International Conference on Data Engineering, and the program co-chairman for the 12th International Conference on VLDB in 1986. He was an associate editor for the IEEE Transactions on Computers for the field of computer networking and distributed processing systems (1978-1982) and received a meritorious award for his service to the IEEE (1983). He was the workshop co-chair of the IEEE First International Workshop on Systems Management, April 1993 and received a Certificate of Appreciation award for his significant service. He is currently a member of the Editorial Board of the Journal of Very Large Data Bases and an Associate Editor for the Journal of Data and Knowledge Engineering. Dr. Chu is the Principal Investigator of an ARPA contract of $1,664,000 (from March 1991 to April 1995) for researching and developing CoBase.
 

Metadata Aggregation - Challenges and the Evolution of OAI-based Services for Scientific and Heritage Content  (slides)

Muriel Foulonneau

Visiting Project Coordinator CIC-OAI Metadata Portal, University of Illinois at Urbana-Champaign, U.S.A.

Abstract:

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), initially published in 2001, has been widely adopted, particularly in the ePrints community and in scientific and cultural heritage institutions such as libraries, museums and archives. To help regulate information sharing and publishing on the Internet, OAI-PMH defines explicit roles and expectations for content and service providers. A number of services have been developed based on OAI-PMH.  Service providers initially struggled with the heterogeneity of content and repositories, but with experience they have been able to implement more and more systems and features to improve data discoverability. The whole environment of metadata aggregation is changing accordingly. A number of new services have been built over aggregations of metadata, notably the CIC metadata portal, the IMLS registry of digital collections, the Digital Library Federation (DLF) Aquifer project, the U.S. National Science Digital Library (NSDL), the American West project, the MetaCombine project, and OAISter. The DLF and the NSDL are jointly developing best practices for OAI implementers. These best practices take into account experiences to date, especially in the science, heritage and library sectors, and emphasize the complexity of metadata related issues for both data and service providers and the importance of a properly balanced share of work and responsibilities between data and service providers.

Biography:

Muriel Foulonneau is project coordinator at the University of Illinois at Urbana-Champaign for the CIC-OAI metadata harvesting project, an initiative for developing common best practices for sharing metadata among the CIC group of research universities in the U.S.A. She is part of the American Digital Library Federation and National Science Digital Library best practices expert group on the Open Archives Initiative and shareable metadata. She previously worked as an IT advisor for the French Ministry of culture and was a participant in Minerva project, a collaboration among European ministries of culture on digitization of cultural heritage resources. She also served as an expert for the European Commission for research projects related to digital heritage. She holds a degree from the National School of Library and Information Science in France.
 

Title: Information, Interface and Interaction in Digital Cities (slides)

Toru Ishida

Professor, Dept. of Social Informatics, Kyoto University, Japan

Abstract:

This talk introduces various trials on Digital City Kyoto towards a social information infrastructure for urban life (including shopping, business, transportation, education, welfare and so on). We propose the three layer architecture for digital cities: a) the information layer integrates both WWW archives and real-time sensory information related to the city, b) the interface layer provides 2D and 3D views of the city, and c) the interaction layer assists social interaction among people who are living/visiting in/at the city. This talk introduces various experiments including crisis management based on technologies such as 3D, animation, agents, distributed vision and mobile computing.
