Summaries in the SBU Rate-A-Course Dialog System Patricia Ding Advisor: Amanda Stent
What is a Summary in Spoken Dialog Systems? • A brief statement that presents the main points in a concise form. • Gives system users a brief overview.
Why Are Summaries So Important? • Information presentations take up the most time in spoken dialogues with computers (Stent et al. 2002). • Summaries take up less time, so they can improve users’ satisfaction (Walker et al. 2002).
What is the Rate-A-Course System? • A survey dialog system that permits college students to evaluate their courses over the telephone (Stent et al. 2006). • Could be used as a replacement for or in addition to other course evaluation methods. • The survey results, which includes comments to open-ended questions, are available in electronic form. They can be distributed over the web or telephone. • Currently, the system only lets students rate courses, not hear others’ ratings.
My Summaries • Basic Summary • Goes through ratings and gives all information about each course rating. • Summary with no and • Better syntax of basic summary. • Parallel Summary • Makes sure the topics for each course rating are presented in the same order. • Easier for users to remember the ratings. • Average Summary • Presents information by topic, rather than by rating. • Shorter summaries = less bored users. • (For the future) User-model Summary • Skip topics the user doesn’t care about.
