Maximum Entropy Markov Models for Information Extraction and Segmentation
We address: modeling sequential data with HMMs, problems with previous methods: motivation, the maximum entropy Markov model, segmentation of FAQs: experiments and results.

Domain Metatheories: Enabling User-Centric Planning
In this paper, we argue that improved usability requires a new representational layer that captures metatheoretic properties of a planning domain.

Ontology Construction Toolkit
The goal of this project was to enable knowledge engineers to construct knowledge bases (KBs) faster. To achieve this goal, we investigated two techniques: knowledge reuse and axiom templates. The…

Bridging the lexical chasm: statistical approaches to answer-finding
This paper investigates whether a machine can automatically learn the task of finding, within a large collection of candidate responses, the answers to questions.

Planning with Conflicting Advice
This paper introduces two contrasting methods for planning with conflicting advice, suited to different user requirements. Soft enforcement embodies a heuristic approach that prefers planning choices that are consistent with…

Coordinating Planning Activity and Information Flow in a Distributed Planning System
Distributed SIPE (DSIPE) is a distributed planning system that provides decision support to human planners in a collaborative planning environment.

A Survey of Research in Distributed, Continual Planning
In this article, we describe a new paradigm for planning in complex, dynamic environments, which we term distributed, continual planning (DCP). We argue that developing DCP systems will be necessary…

Characterizing the Performance of Multiple-Image Point-Correspondence Algorithms using Self-Consistency
A new approach to characterizing the performance of point- correspondence algorithms is presented.

At the Boundary of Workflow and AI
This paper describes how techniques from the AI community, specifically reactive control, planning, and scheduling, could be leveraged to develop powerful, next-generation adaptive workflow engines that provide many of the…

Task-based Information Management
We are constructing a system, called the Task-based Information Distribution Environment (TIDE), that delivers information to participants in a dynamic collaboration by evaluating the relevance of incoming and newly generated…

What we do not know about sequence analysis and sequence databases
The marriage of high-throughput nucleotide sequencing with computational methods for the analysis of nucleotide and protein sequences have ushered in a new era of molecular biology.

CPEF: A Continuous Planning and Execution Framework
This article reports on the first phase of the continuous planning and execution framework (CPEF), a system that employs sophisticated plan-generation, -execution, -monitoring, and -repair capabilities to solve complex tasks…
