Abstract
We demonstrate a conversational interface that assists pedestrian users in navigating within urban environments and acquiring tourist information by combining spoken dialogue system, question-answering (QA), and geographic information system (GIS) technologies. In contrast to existing mobile applications which treat these problems independently, our Android agent addresses the problem of navigation and touristic question-answering in an integrated fashion using a shared dialogue context with multiple interleaved dialogue threads. In this paper, we present the architecture and features of our latest system, extended from an earlier version which was built and evaluated with real users (Janarthanam et al., 2013). The new features include navigation based on visible landmarks, navigation adapted to the user's previous route knowledge, and tourist information pushing based on visible and proximal points-of-interest. The system also uses social media to infer "popularity" of geographical entities.
