Title: DUDU: A TURKISH DIALOGUE CORPUS GENERATOR FOR MEDICAL DOMAIN

Abstract:
Domain-oriented dialogue datasets are essential for building dialogue systems. TV subtitles enable the construction of these datasets because of including large amounts of dialogue material but lack speaker information and the turn structure. In this paper, we present a novel method to build a Turkish and domain-specific dialogue corpus called as DuDu (Dialogue Dataset) from monolingual scripts and their corresponding Turkish subtitles. Initially, we align each sentence with its translation considering timeline information for Turkish subtitles. Then, we employ our similarity method using knowledge base embeddings. This method matches the utterances between scripts and subtitles and assigns the speaker and dialogue boundaries for aligned subtitles. Finally, we evaluate the quality of the constructed corpus with existing mainstream methods. We examine a combination of both feature and embedding-based response retrieval method and experiments of this combined mainstream method achieve 0.675 F1 score.
