Associative Thinking Agent
Figure 1. The proposed system allows any entity that can provide associative data to interested parties to register as associative thinking agent source. This includes general-purpose search engines like Google, specialized search engines like the Internet Archive, and ordinary users of personal computers. Associative thinking agents, residing on personal computers, help the user identify sources and information relevant to the user’s current task.

Associative Source API and Registry
• A common search/link info API
• A central UDDI registry
• Allows for meta-search clients with dynamic lists of sources.
Clients can access even those sources created after the client itself.

Connecting Personal Webs
People create knowledge-- bookmarking, annotating, linking, synthesizing-- every day.
People are lousy about taking the extra step to communicate this knowledge.
