Multi-Party Dialogue Corpus

Abstract

Adequate dialogue data is needed to investigate the multi-party interaction with a computer system as an independent dialogue partner in the conversation with several humans. A look is taken at existing multi-party corpora in order to see if any of these could be used to investigate our research questions. The presented collection is limited to corpora that make use of multiple modalities. Although a wide variety of corpora is available, as far as the authors are aware, there is no existent collection of data that stresses the designated features important for our research. Thus, we perform the data collection presented in this chapter. We deploy the Wizard-of-Oz technique as introduced in Section 2.1 to simulate the envisaged system in the example domain of restaurant selection (refer to Section 1.3 for a description of the system) to obtain realistic interaction data which is then used to assist the development of the system (Chapter 4) and for evaluation (Chapter 5). The WOZ recording setup and procedure are presented in Section 3.2 followed by a detailed description of the software tool we have developed to support the recordings. The tool is easily adaptable to other domains and requirements and publicly available for other developers. The collected data results in the PIT corpus which is finally presented in Section 3.3.
