Collarity was co-founded in 2005 by Levy Cohen and Emil Ismalon based on the idea that data related to web user interactions with web content (sometimes referred to as passive filtering) could be used to improve search relevance, as an alternative to the historical emphasis on link analysis or explicit user feedback systems. The company was officially launched in November 2006.
Collarity's technology is focused in the area of collaborative filtering attempting to leverage anonymous implicit web user data (e.g., articles/videos searched on or clicked), as opposed to explicit metadata such as tagging or rating, with the goal of creating an information value hierarchy. The intent is for this base of behavioral knowledge to ultimately make specific information more findable for specific online audience segments.
The technology is related to currently popular notions of The Wisdom of Crowds, "harnessing collective intelligence" (a core tenet of Tim O'Reilly's original Web 2.0 definition), and "the database of intentions" (a phrase coined by John Battelle in his book The Search. ISBN 1-59184-088-0. ). Collarity's technology development has been mentioned in several search innovation articles and has been highlighted in others.
Collarity delivers what they call an audience engagement platform enabling web publishers to guide their web visitors to relevant content based on the historical content consumption patterns of previous site customer segments. The platform also enables web publishers to dynamically target advertising based on how specific site segments have responded to ads in the past.
