SIMULATING A NEW WORLDSIMULATING A NEW WORLD
Obtain discipline-scale collection MEDLINE from NLM, 10M bibliographic abstracts human classification: Medical Subject Headings
Partition discipline into Community Repositories 4 core terms per abstract for MeSH classification 32K nodes with core terms (classification tree)
Community is all abstracts classified by core term 40M abstracts containing 280M concepts concept spaces took 2 days on NCSA Origin 2000
Simulating World of Medical Communities 10K repositories with > 1K abstracts (1K w/ > 10K)

Rice InterspaceRice Interspace Gather the Information Sources
each (college, class, student) has repository each (department, lab, faculty) has repository
Generate the Community Repositories text documents with articles and annotations specialty datatypes: databases and motifs
Construct the Analysis Environment federated concept switching across sites type-dependent parsing for text/data interlinks
