Why Worksets?
• The result of a first-level, rough filter
• Better scale for intensive analytics
• Provides essential scope for certain analytics
– Word frequency scope over Bacon’s essays
• Some tools (are trained to) work best on a
narrow, homogeneous work-set
• Eliminate noise that would otherwise arise by
asking questions across whole of HT
