Tartan is a social bot that engages users in sharing daily personal experiences in multiple domains. Our work contributes to Conversational AI in two aspects: 1) We extract common-sense knowledge expressed in large-scale user utterances in conversations, and find that more than 20% of the shared information is related to personal life, such as social relationships and individual activities. 2) Based on the underlying structure of daily life common sense knowledge, we decompose the task of open-domain social chat into a dialog management problem over a set of independent topical bots. In addition to analysis of the effectiveness of the critical components in our design, we also present analysis on the breadth of common sense knowledge expressed in conversational language and the depth of conversations that can be grounded on common sense knowledge.
