We describe our efforts in designing and building the multimodal Bell Labs Communicator system. Several innovations are necessary for generalizing the speech-only user interface and the semantic/pragmatic algorithms to handle both speech and visual modalities, including changes to the parser, semantic and pragmatic modules to integrate better the user input from different modalities within and across dialogue turns, as well as extending the concept of e-forms to include visual modality. The paper also describes the design of a natural, consistent and efficient multimodal user interface. We introduce the concept of "dominant modality": the system adaptively tracks the most probable interaction mode and suggests that modality to the user. Modality tracking provides an elegant solution to the "turn-taking" issue in multimodal spoken dialogue systems.

We've been investigating how to use Gaussian mixture continuous-density hidden Markov, models (CDHMMs) for handwritten Chinese character modeling and recognition. We've identified and developed a set of techniques that can be used to construct a practical CDHMM-based offline recognition system for a large vocabulary of handwritten Chinese characters. We have reported elsewhere the key techniques that contribute to the high recognition accuracy. In this paper we describe how to make our recognizer compact without sacrificing too much of the recognition accuracy. We also report the results of a series of experiments that were performed to help us make a good decision when we face several design choices.
In this paper, we compare three representative modeling approaches, namely the multiple-prototype-based template matching approach, the subspace approach and the continuous density hidden Markov model approach for lar...

The paper proposed a new syntactic annotation scheme - functional chunk, which tried to represent information about grammatical relations between sentence-level predicates and their arguments. Under this scheme, we built a Chinese chunk bank with about two million Chinese characters, and developed some learned models for automatically annotating fresh text with functional chunks. We also proposed a two-stages approach to build Chinese tree bank on the top of chunk bank, and gave some experimental results of chunk-based syntactic parser to show the advantage of functional chunk for parsing performance increase. All these work lays good foundations for further research project to build a large scale Chinese tree bank.
We present an algorithm for computing the distance between two free-form surfaces. Using line geometry, the distance computation is reformulated as a simple instance of a surface-surface intersection problem, which le...
