Segmenting Reactions to Improve the Behavior of a Planning/Reacting Agent
In this paper, we examine the problem of selecting the best set of reactions for an agent to store. In particular, we examine the benefit of including {em intervals} of…

Scatter/Gather Browsing Communicates The Topic Structure Of A Very Large Text Collection
Users are presented with automatically computed summaries of the contents of clusters of similar documents and provided with a method for navigating through these summaries at different levels of granularity.…

Agent Development Tools for the Open Agent Architecture
The ADT provides a variety of mechanisms that support the specification and implementation of individual agents, as well as cooperating communities of agents. This paper discusses a number of general…

Strategic Advice for Hierarchical Planners
This paper describes an Advisable Planner framework that marries an advice-taking interface to AI planning technology. The framework is designed to enable users to interact with planning systems at high…

Canonical representations for the geometries of multiple projective views
We present a new unified representation which will be useful when dealing with multiple views in the case of uncalibrated cameras.

Database Links are a Foundation for Interoperability
This article provides an overview of the DB-interoperation problem, and offers several solutions. It discusses how links are used in molecular biology DBs, and describes the potential stumbling blocks when…

Statistical Language Modeling for Speech Disfluencies
We introduce a language model that predicts disfluencies probabilistically and uses an edited, fluent context to predict following words. It uses dynamic programming to compute the probability of a word…

The Fundamental matrix: theory, algorithms, and stability analysis
We analyze in some detail the geometry of a pair of cameras, i.e., a stereo rig. Contrarily to what has been done in the past and is still done currently,…

A Machine Learning Architecture for Optimizing Web Search Engines
We describe a wide range of such heuristics including a novel one inspired by reinforcement learning techniques for propagating rewards through a graph|which can be used to affect a search…

Designing For Cognitive Communication: Epistemic Fidelity Or Mediating Collaborating Inquiry
aps between worldviews prevent students from interpreting displays literally, and thus limit the extent to which communication can be achieved by representing knowledge accurately. Hence, rather than merely representing mental…

A Phone-Dependent Confidence Measure for Utterance Rejection
An acoustic confidence measure for acceptance/rejection of recognition hypotheses for continuous speech utterances is proposed. This measure is useful for rejecting utterances that are out of domain, or contain out-of-vocabulary…
