Heceta is part of the Fogcutter suite of tools for building intelligent applications.
Heceta is a search engine that leverages all of the various bits of information from Neddick, Quoddy, and "Other" systems to provide better / deeper / more insightful search results than you can get from simple document content analysis. Intranet search in organizations is usually very poor, largely because page-rank type algorithms don't work well due to the lack of links between documents. But by supplementing the content analysis with scoring based on tags, social graph connections, activity-stream information, etc., and applying machine-learning / artificial-intelligence techniques Heceta can do a superior job of locating the knowledge and information a user needs.
