AIR represents a fundamentally new approach to ranking web pages that integrates advanced concepts from Applied Physics and Engineering Dynamics. AIR identifies exceptional web pages by understanding the level of interconnection between valuable sites from within specific fields of interest. AIR evaluates a web page based on what other "knowledgeable" sites in that specific field say about the page, and also evaluates the page based on what the page says about other "knowledgeable" sites in the specific field.

"By obtaining the standing of a web page within a given topic,'s AIR technology is able to provide exceptionally focused search results for users," Yun continues.
