PERSONAL VIRTUAL ASSISTANT WITH SEMANTIC TAGGING

A computer based method for performing a command via a voice user interface on a subset of objects. The subset is selected from a set of objects, each having an object type. At least one taggable field is associated with the object type and has a corresponding value. The set of objects is stored in the computer memory. An utterance is received from the user and includes a command, an object type selection, a taggable field selection, and a value for the taggable field. Responsive to the utterance, at least one object is retrieved from the set of objects, the object of the type selected by the user and having a value in the taggable field selection that matches the taggable field value received from the user. The command is performed on the object. The object consists of text which is converted to voice output.
