We investigate using the PARADISE framework to develop predictive models of system performance in our spoken dialogue tutoring system. We represent performance with two metrics: user satisfaction and student learning. We train and test predictive models of these metrics in our tutoring system corpora. We predict user satisfaction with 2 parameter types: 1) system-generic, and 2) tutoringspecifi...

1834), the English Romantic poet, wrote, “If a man could pass through Paradise in a dream, and have a flower presented to him as a pledge that his soul had really been there, and if he found that flower in his hand when he [awakes]—Aye, what then?” Coleridge’s scenario is not hypothetical. On the edge of death, millions of people have passed through what seems to them a paradise. This phenomeno...

The design of methods for performance evaluation is a major open research issue in the area of spoken language dialogue systems. This paper presents the PARADISE methodology for developing predictive models of spoken dialogue performance, and shows how to evaluate the predictive power and generalizability of such models. To illustrate the methodology, we develop a number of models for predictin...

In this paper, we introduce the PARADISE search engine in TREC09 Web track. PARADISE is the abbreviation for Platform for Applying, Research and Developing Intelligent Search Engine, which is a search engine platform developed by SEWM group, Peking University. The system is designed to support both English and Chinese information retrieval. This system preprocessed and indexed the five hundred ...

Birds-of-paradise are nature's prime examples of the evolution of color by sexual selection. Their brilliant, structurally colored feathers play a principal role in mating displays. The structural coloration of both the occipital and breast feathers of the bird-of-paradise Lawes' parotia is produced by melanin rodlets arranged in layers, together acting as interference reflectors. Light reflect...
