Research and Development Team Structure

As recommended by the ADL Advisory Board, the organization of the ADL teams has been changed to better reflect their functioning as follows:

• Information Systems Research Team
  Membership: Singh (leader), Agrawal, El Abbadi, Kothuri, Prabhakar, Smith, Su, Wu
  Mission: The Team's research is focused on a number of issues pertaining to the architecture of digital libraries including resource discovery, extensible data store, and the implications of building a geographically referenced database. In rela tion to geographically referenced databases, issues under investigation include multi-dimensional indexing, data placement, tertiary storage, content-based retrieval, and performance tuning.

• Performance and Parallel Processing Research Team
  Membership: Yang (leader), Andresen, Egecioglu, Ibarra, Poulakidas, Watson, Zheng
  Mission: The goal of the Performance and Parallel Processing Team is to identify and investigate aspects of ADL that will benefit from high-performance computing on multi-computers. Current investigation is focused on various performance issues arising from the ADL environment in terms of both space and time complexities, including WWW applications. It is also developing algorithms and software techniques for efficient image processing for high performance digital libraries.

• Image Processing Research Team
  Membership: B. Manjunath (leader), Y. Ma, S. Mitra, N. Stroebel, Y. Wang
  Mission: The goal of the Image Processing Team is to investigate issues concerning the representation, storage, and access of image-related data. The Team also aids the implementation team in adapting their research findings and recommendations for the testbed system. Particular foci of activity for the Team are wavelet decompositions for storage, manipulation and transmission of images, and access of images by content.

• Geospatial Information Research Team
  Membership: Goodchild (leader), Carver, Geffner, Hill, Kemp, Kothuri, Larsgaard, Smith
  Mission: Responsible for investigating a variety of issues relating to the integration of spatially referenced information objects into ADL.

• Collection Development Team
  Membership: Carver (leader), Goodchild, Hajic, Larsgaard, Simpson, Smith
  Mission: Oversee ADL collection development plans, including criteria for new additions to the collection. Prioritization and schedule for loading new data into ADL. Track issues related to data formats, data ingest and analysis tools, catalog maintenance.

• Systems Engineering Team
  Membership: Frew (leader), Andresen, Colucci, Freeston, Hajic, Lovette, Nideffer, Simpson, Zheng
  Mission: Responsible for design and implementation of ADL on-line query and retrieval services, and for overall integration of all ADL services into operational and research testbed system.

• User Interface Design & Implementation Team
  Membership: Nideffer (leader), Lovette, Freitas
  Mission: Design and implement ADL user interface.

• User Interface Evaluation Team
  Membership
  UCSB Subteam: Hill (leader), Carver, Dolin, Frew, Larsgaard, Rae, Simpson
  Colorado Subteam: Buttenfield (leader) Larsen, Reitsma, Kersky, Tsou, Rokoske, Rock, Smith, Kole
  Mission: Evaluate the effectiveness of the ADL system from the perspective of potential user of the system. Knowledge gained from these evaluation activities is used to inform the design and implementation of ADL, and to document in detail the effectiveness of ADL and areas calling for improvement, both in the interface design and in the underlying system functionality and content.

• Digital Library Requirements Team
  Membership: Smith (leader), Carver, Colucci, Frew, Hill
  Mission: Define set of library services that will define current and future ADL systems.
