Community Information Management

• Numerous Web communities
• database researchers, movie fans, legal
  professionals, bioinformatics, etc.
• enterprise intranets, tech support groups
• Each community many data sources many
  members
• Members often want to integrate data, query, and
  discover community information
• any interesting connection between researchers X
  and Y?
• find all citations of this paper in the past one
  week on the Web
• what is new in the past 24 hours in the database
  community?
• what are current hot topics? who has moved where?
