Existing approaches to text generation fail to consider how interactions with the user may be managed within a coherent explanation or description. This paper presents an approach to generating such interactive explanations based on two levels of discourse planning { content planning and dialogue planning. The system developed allows aspects of the changing context to be monitored with an expla...

Three questions to ask of a proposal for a shared evaluation task are: whether to evaluate, what to evaluate and how to evaluate. For NLG, shared evaluation resources could be a very positive development. In this statement I address two issues related to the what and how of evaluation: establishing a “big picture” evaluation framework, and evaluating generation in context.

This paper describes an integrated architecture for online collaborative multimedia (audio and text) meetings which supports the recording of participants' audio exchanges, automatic metadata generation and logging of users editing interaction and also information derived from the use of group awareness widgets (gesturing) for post-meeting processing and access. We propose a formal model for ti...

covering arrays of strength two have been widely studied as combinatorial models of software interaction test suites for pairwise testing. while numerous algorithmic techniques have been developed for the generation of covering arrays with few columns (factors), the construction of covering arrays with many factors and few tests by these techniques is problematic. random generation techniques c...

In this paper, we study how to generate entanglement by interaction-free measurement. Using Kwiat et al.’s interferometer, we construct a two-qubit quantum gate that changes a particle’s trajectory according to the other particle’s trajectory. We propose methods for generating the Bell state from an electron and a positron and from a pair of photons by this gate. We also show that using this ga...
