Towards Continuous Dialogue Corpus Creation: writing to corpus and generating from it

This paper describes a method to create dialogue corpora annotated with interoperable semantic information. The corpus development is performed following the ISO linguistic annotation framework and primary data encoding initiatives. The Continuous Dialogue Corpus Creation (D3C) methodology is proposed, where a corpus is used as a shared repository for analysis and modelling of interactive dialogue behaviour, and for implementation, integration and evaluation of dialogue system components. All these activities are supported by the use of ISO standard data models including annotation schemes, encoding formats, tools, and architectures. Standards also facilitate practical work in dialogue system implementation, deployment, evaluation and re-training, and enabling automatic generation of adequate system behaviour from the data. The proposed methodology is applied to the data-driven design of two multimodal interactive applications - the Virtual Negotiation Coach, used for the training of metacognitive skills in a multi-issue bargaining setting, and the Virtual Debate Coach, used for the training of debate skills in political contexts.
