Crowdsourced Multimodal Corpora Collection Tool

Abstract

In recent years, more and more multimodal corpora have been created. To our knowledge there is no publicly available tool which allows for acquiring controlled multimodal data of people in a rapid and scalable fashion. We therefore are proposing (1) a novel tool which will enable researchers to rapidly gather large amounts of multimodal data spanning a wide demographic range, and (2) an example of how we used this tool for corpus collection of our "Attentive listener'' multimodal corpus. The code is released under an Apache License 2.0 and available as an open-source repository, which can be found at https://github.com/kth-social-robotics/multimodal-crowdsourcing-tool. This tool will allow researchers to set-up their own multimodal data collection system quickly and create their own multimodal corpora. Finally, this paper provides a discussion about the advantages and disadvantages with a crowd-sourced data collection tool, especially in comparison to a lab recorded corpora.
