Abstract

An ontology based task oriented dialogue as an interface to an user developing applications using natural language instructions is presented. The dialogue system represents the domain knowledge in an OWL2 ontology that is consulted and updated in the interpretation of the user utterances. The utterances are processed using an Universal Dependencies parser whose output is then interpreted to obtain a partial semantic representation. The pragmatic interpretation computes a set of possible interpretations by matching the partial representation with the ontology information, classes, properties, instances and data properties values, such as names. The dialogue manager is able to use soft constraints to choose the set of best interpretations. A set of preliminary experimental cases with promising results is also presented.
