The Big Picture
• Find the words
• Index the words
• Do ranked retrieval
• Use that system to find what you want

Some Issues
• Language-based search without language!– Shape codes
• Accuracy-selection effect of ranked retrieval– Poor recognition scatters in the query-term space
• Blind relevance feedback– Based on clean text
• Image-domain summaries

Some Applications
• Case management for litigation
• Duplicate detection for declassification productivity and anti-tiling
• Knowledge management from everything I have ever xeroxed or faxed
