Interspace Semantic Middleware (DARPA, 1997-2000, $1.1M): Principal investigator (PI) of an
DARPA-funded project on “The Interspace Prototype: An Analysis Environment based on Scalable
Semantics.” The foundation of our proposed analysis environment will be a “semantic middleware” for
scalable distributed services, which consist of a hierarchy of statistical and pattern analysis algorithms that
are valid across the range of object types (e.g., texts and images) and subject domains. This middleware
will be used to construct a prototype Interspace with large collections across text (abstracts in engineering)
and image (aerial photos in geography), and then across subjects (medical thesaurus relationships) and
classifications (personal Web documents). We plan to use NCSA-unique computing, network, and
visualization resources as a “time-machine” to simulate a generation-after-next hardware and software
environment. (Collaborators: B. Schatz, B. Pottenger, D. Lawrie at UIUC, M. Ramsey, T. Ng, K. Tolle, B.

related to spatially-oriented, multimedia geographic information access. Based on the concept space
approach developed by the Illinois Digital Library Initiative (DLI) project and the Alexandria (University
of California at Santa Barbara) geo-referenced collections, this research proposes to develop knowledge
representations and structures to capture concepts of relevance to spatial and multimedia information
(natural language phrases and geo-related textures). Selected machine learning techniques and general
Artificial Intelligence (AI) graph traversal algorithms will also be adopted to assist in semantic, concept-
based spreading activation in integrated knowledge networks. (Collaborators: T. Smith, B. Schatz, L.
