Methods, software and devices for responding to a user query are disclosed. A user query received from a user is matched to stored responses to obtain initial matched responses. A confidence metric indicating the likelihood of the initial matched responses satisfying the user query is calculated. Upon determining the confidence metric to be below a specified threshold, the user query is supplemented with contextual data, The user query, supplemented by contextual data, is further matched to stored responses by applying disparate matching techniques to obtain further matched responses, where at least one of the disparate matching techniques differs from techniques used to obtain the initial matched responses. Degree-of-match metrics are calculated taking into account the contextual data, where each degree-of-match metric indicates a quality of match between the user query and a matched response. At least one of the matched responses is presented to the user. |
