  5. Integrate information retrieval in desktop applications • As user writes, browses, creates • Zero-input interface • No context switch to search • Impromptu information discovery

  6. Letizia • Local Reconnaissance • As user looks at document, use idle time to crawl and choose best “link” • “Link” not just one degree away: the neighborhood of the page • Letizia Demo (film clip)

  7. Powerscout • Global Reconnaissance • Semantic Neighborhood of page • Concept Browsing “the idea of browsing links not specified by a document's author, but nonetheless semantically relevant to the document being viewed.
