Abstract
Apparatus, systems and methods for contextual query revision are disclosed. A current search query is received during a search session. The current search query includes one or more current search tokens. Potentially inaccurate search tokens are identified from the one or more current search tokens. A possible replacement token is identified based upon the potentially inaccurate search token. A group of related tokens is identified from query logs, and a modified search query is generated if the replacement token is not included in the related tokens.
