Dialogue state tracking accuracy improvement by distinguishing slot-value pairs and dialogue behaviour

<div><p>Dialog state tracking (DST) plays a critical role in cycle life of task-oriented dialogue system. DST represents the goals consumer at each step by and describes such objectives as conceptual structure comprising slot-value pairs actions that specifically improve performance effectiveness systems. faces several challenges: diversity linguistics, dynamic social context dissemination over candidate values both slot acts determined ontology. In many turns during dialogue, users indirectly refer to previous utterances, produce challenge distinguishing use related history, Recent methods used popular for are ineffective. this paper, we propose historical self-Attention framework recognizes relevant including user utterance beside current utterances system where specific piers variations uses together with weighted outperform existing models recognizing relevance utterance. For evaluation proposed model WoZ dataset was used. The implementation attempted prior encoder second additional score combined all utterances. obtained 0.8 per cent better results than state-of-the-art precision target, but is not turnaround submission.</p></div>
