DialCrowd: A toolkit for easy dialog system assessment

Abstract

When creating a dialog system, developers need to test each version to ensure that it is performing correctly. Recently the trend has been to test on large datasets or to ask many users to try out a system. Crowdsourcing has solved the issue of finding users, but it presents new challenges such as how to use a crowdsourcing platform and what type of test is appropriate. DialCrowd makes system assessment using crowdsourcing easier by providing tools, templates and analytics. This paper describes the services that DialCrowd provides and how it works. It also describes a test of DialCrowd by a group of dialog system developers.
