1. A computing system comprising: a storage unit configured to receive an input query; and a control unit, coupled to the storage unit, configured to: identify input query components in the input query; detect a query conflict between one or more of the input query components based on inclusion of the input query components in a conflict set, wherein the conflict set is a set of associated semantic concepts defining a scope of the conflict; generate a conflict free query by replacing one of the input query components based on query context including a historical context, a user context, and a current context of a user making the input query, wherein: the historical context includes past usage or behavior of the user; the user context includes preferences and other factors associated with the user, including appointments and personal relationships of the user: the current context includes events occurring at the time the input query is made, including communications received by the user, a time of day, a location of the user, and current activities of the user; and generate a query response for the conflict free query for displaying on a device.
