Toward Establishing Trust in Adaptive Agents
We present the results of a study among test users of CALO, one such complex adaptive agent system, to investigate themes surrounding trust and understandability. We identify and discuss eight…

Template-Based Structured Argumentation
Collaborative analysis is supported via simultaneous access to arguments through web browser clients connected to a common argument server.

Using a Semantic Wiki as a Knowledge Source for Rich Modeling and Question Answering
We are exploring the following hypothesis at the intersection between knowledge engineering and the semantic web: Can we use a semantic wiki to acquire symbolic knowledge on the web that…

An Email Assistant That Learns to Suggest Reusable Replies
We have implemented an approach in which rapid improvement in performance at suggesting reusable text is achieved by learning from limited user feedback.

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,…

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…

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.

An Intelligent Personal Assistant for Task and Time Management
We describe an intelligent personal assistant that has been developed to aid a busy knowledge worker in managing time commitments and performing tasks. The system draws on a diverse set…

Proactive Behavior of a Personal Assistive Agent
Our model for proactive assistance employs a meta-level layer to identify potentially helpful actions and determine when it is appropriate to perform them. We conclude by identifying technical challenges in…

Deductive Biocomputing
We describe a deduction-based approach to biocomputation that semiautomatically combines knowledge, software, and data to satisfy goals expressed in a high-level biological language.
