Ivan Tashev, Michael L. Seltzer, Yun‐Cheng Ju, Dong Yu, Alex Acero · 2007
In this paper, we describe a telephone dialog system for location-based services.In such systems, the effectiveness with which both the user can input location information to the system and the system delivers location information to the user is critical.We describe strategies for both of these issues in the context of a dialog system for real-time information about traffic, gas prices, and weather.The strategies employed by our system were evaluated through user studies and a system employing the best strategies was deployed.The system is evaluated through an analysis of 700 calls over a two month period.S: Welcome to Commute UX.Would you like traffic, gas prices, or weather?U: I need the closest gas station in Redmond.S: In that case, I need you to tell me the intersection where you are.U: I'm on the corner of 148 th and 35 th .S: You are at the corner of 148 th Avenue NE
