Neptune: a Mixed-Initiative Environment for Planning and Scheduling
We describe the design of a user-centric, integrated planning and scheduling system that assists the user in exploring the rich space of plans and associated resource assignment options in complex,…

RADAR: a Personal Assistant That Learns to Reduce Email Overload
This paper describes the integration of diverse AI technologies and presents results from human evaluation studies comparing RADAR user performance to unaided COTS tool users and users partnered with a…

A Process Catalog for Workflow Generation
This paper describes PROCAT, an implemented ontology-based catalog for components, built on a layered representation that allows reasoning about processes at varying levels of abstraction, from qualitative constraints reflecting preconditions and…

A Demonstration of the Radar Personal Assistant
Email clients were not designed to serve as a task management tools, but a high volume of task-relevant information in email leads many people to use email clients for this…

A Framework for Evidential-Reasoning Systems
Both the formal basis and a framework for the implementation of automated reasoning systems based upon these techniques are presented. The formal and practical approaches are divided into four parts.

Outdoor Mapping and Navigation Using Stereo Vision
We consider the problem of autonomous navigation in an unstructured outdoor environment. The goal is for a small outdoor robot to come into a new area, learn about and map…

Sampling Stable Properties of Massive Track Datasets
In this paper, we explore ways in which stable properties of sensor observations can be extracted and visualized using a statistical sampling of features from a very large track dataset,…

Enabling Experts to Build Knowledge Bases from Science Textbooks
As a near-term goal, we are focusing on enabling subject matter experts (SMEs) to construct declarative knowledge bases (KBs) from 50 pages of a science textbook in the domains of…

Detecting and Summarizing Action Items in Multi-Party Dialogue
This paper addresses the problem of identifying action items discussed in open-domain conversational speech, and does so in two stages: firstly, detecting the subdialogues in which action items are proposed,…

A Preference Model for Over-Constrained Meeting Requests
We develop a preference model designed to capture user scheduling preferences for overconstrained meeting requests between multiple people, and a methodology for preference elicitation to initially populate this model.

Efficient Message Passing and Propagation of Simple Temporal Constraints
We first show that for an STN, these messages can be represented compactly as sub-STNs. We then present an efficient message passing scheme for computing the minimal constraints of an…
