abstract:
The wide interest in ambiguities is because it represents uncertainty but also a fundamental item of discussion for who is interested in the interpretation of
languages also considering that it is functional for communicative purposes. This paper addresses ambiguity issues in terms of identifcation of the meaningful features of multimodal ambiguities and it evaluates
a dynamic HMM-based classifcation method that is able to classify ambiguities by learning, and progressively adapting the model to the evolution of the interaction, refning the existing classes, or identifying new ones. The comparative evaluation of the considered method of the considered method with other surveyed methods demonstrates an improvement considering the performance evaluation measures.
