Abstract
A method, a system and a computer program product for interpreting a verbal input in a multimodal dialog system are provided. The method includes assigning (302) a confidence value to at least one word generated by a verbal recognition component. The method further includes generating (304) a semantic unit confidence score for the verbal input. The generation of a semantic unit confidence score is based on the confidence value of at least one word and at least one semantic confidence operator.
Claims15
A method for interpreting a verbal input in a multimodal dialog system, the multimodal system being an apparatus that comprises input and output devices and a processing system, the method comprising:
- receiving the verbal input at an input device of the multi modal dialog system,
- generating a word sequence from the verbal input by a verbal recognition component of the processing system using a recognition grammar, the word sequence comprising at least one word that is semantically tagged;
- assigning by a value assigner component of the processing system a confidence value to each of the at least one word generated by the verbal recognition component, based on the word's semantic importance;
- generating by a score generator of the processing system a semantic unit confidence score for the word sequence, the generation of the semantic unit confidence score being based on the confidence value of each of the at least one word and at least one semantic confidence operator;
- and
- generating an output by a human interface output device based on the semantic unit confidence score.
A multimodal dialog system for interpreting a verbal input, the multimodal dialog system comprising:
- an input device that receives the verbal input;
- an input processor that comprises:
- a verbal recognition component that generates a word sequence comprising at least one word from the verbal input using on a recognition grammar, the word sequence comprising at least one word that is semantically tagged,
- a value assigner component, that assigns a confidence value to each of the at least one word generated by the verbal recognition component, based on the word's semantic importance, and
- a score generator that generates a semantic unit confidence score for the verbal input, the generation of the semantic unit confidence score being based on the confidence value of the at least one word and at least one semantic confidence operator;
- and
- a human output device that generates a human interface output based on the semantic unit confidence score.
