about me



I am a Research Scientist in the Relational Agents group at Northeastern University. Our lab creates animated, conversational agents that build long-term relationships with their users. Systems we are currently fielding act as coaches for a variety of lifestyle changes in the area of behavioral medicine. We are currently in the pilot phase of a system to encourage walking in older adults with low health literacy.
My own research focuses on computational modeling for referring expressions in dialog. Recently, I have concentrated on the special problems that come up for embodied, situated dialog agents.

Active Projects:

  • Establishing and Breaking Conceptual Pacts with Dialog Partners
    People use the identity of the person speaking to them when they comprehend language. Between a pair of discourse partners, their interaction history creates expectations of the way objects will be described, and when the speaker complies with those expectations, comprehension is faster (as measured by eye-gaze fixations). However, when speaking to a different dialog partner, the expectations are reset. In computational terms, this would be a reset point in the discourse context.

    The goal of this project is to understand whether language comprehension works the same when humans converse with animated dialog agents. The results will impact the future design of noun phrase generation for dialog agents, as well as behavioral models for relation-building agents.

    This project is supported by the National Science Foundation.

  • The GIVE Challenge: Generating Instructions In Virtual Environments
    GIVE is a challenge problem for natural language generation. We have built a test platform in which systems can be matched with online users through a web interface, and test their mettle in generating intelligible instructions that direct the human partner to solve a treasure hunt task (there are three different tasks in GIVE-2009, with varying levels of difficulty). The results of over 1000 system runs will be presented in the GIVE workshop at ENLG in 2009, and we will show a demo at EACL 2009. For more details, see the Press Release, Play a game (only until 1/31/2009), or stay tuned here for updates.

  • CIVET: Collaborative Interaction in Virtual EnvironmenTs
    Software agents that are embodied and mobile within a 3D space are a core component of many exciting developing application areas within AI. Examples are unmanned autonomous vehicles, assistant robots like domestic helpers or hospital couriers, or characters that run within simulated worlds for training, entertainment, or social interaction. These sorts of agents need to carry on a dialog while also having a shared experience of the external world with their human partner, and they also must understand spatial relationships between the dialog partners and objects in the world that are under discussion, which requires a variety of dialog skills that existing software does not model.

  • Computational Models for Zero Anaphors in Korean
    In languages such as Korean, Japanese, Spanish and Portuguese that make heavy use of null anaphors, are null anaphors used in the same circumstances as overt pronouns in languages like English? If they are like English overt pronouns, they may yield to the same processing models as we use for English pronouns. Intuitively, it would seem that null anaphors would appear in highly predictable positions, and their meaning would therefore be easy to calculate. But when the language has both overt and null anaphora, as Korean does, do the two forms need different processing? Computer-readable texts and transcripts have recently become available that allow us to investigate these questions.

  • Bootstrapping Linguistic Resources
    AI system development has always been plagued by the problem of codifying human knowledge and experience in computer form. Natural language systems are no exception. For spoken dialog systems, all of the vocabulary items and concepts that a particular system needs to be able to discuss must be painstakingly defined by hand. With the availability of large knowledge collections such as the WWW, it has recently become more feasible to automatically bootstrap linguistic knowledge for a system under development. Like many other labs, we are experimenting with techniques to bootstrap vocabulary items, examples of larger constituents such as full sentences, and concepts for a particular domain from the web.
