Last month Attivio announced general availability of the Attivio Active Intelligence Engine™ (AIE) version 2.1. AIE 2.1 includes a slew of new features and refinements that collectively realize our widely accepted (and often imitated) vision: Unified Information Access (UIA). Simply put, UIA asserts that information, regardless of type, needs to be available to users through a single interface. Of course the user is free to consume the information using a variety of methods: search interfaces, Business Intelligence (BI) tools, reporting engines, and applications - which may be search or BI based, or entirely new combinations of any of those.
One of the new core features in AIE 2.1 is the Key Phrase or Statistically Improbable Phrase extractor. It looks at the frequency of words and phrases in a document and finds the phrases that best distinguish the document from a large group of "background" documents. These words and phrases aren't usually named entities, but they're informative about the content of the document. The extracted key phrases are aggregated in a multi-value field and can then be presented as a facet.
