Title: Spoken-Dialogue Healthcare Companionbots for Elders
Abstract: The percentage of the population over the age of 65 in most developed countries is expected to increase significantly by the year 2030. In the U.S. it will increase by about two thirds, rising from 12 to 20%. With over 50% of hospital patients and 36-50% of healthcare costs attributed to this population, it is critical that we act now to avoid a future healthcare crisis. The Companionbots project is building the framework for perceptive, emotive, spoken-dialogue, companion robots that will proactively monitor, educate, train, motivate and provide therapy to elders. The first part of this talk will discuss Companionbots for Therapeutic Dialogue on Depression. This discussion will emphasize prior and planned research in semi-supervised machine learning algorithms to improve reasoning based on multi-modal input streams including vision, speech, and language. The second part of the talk will discuss the knowledge representation that will be used to construct a user model and track the dialogue history, along with a domain-independent semantic analysis approach to compare the semantics of two utterances in this representation.
