Information extraction with HMM structures learned by stochastic optimization
This paper demonstrates that extraction accuracy strongly depends on the selection of structure, and presents an algorithm for automatically finding good structures by stochastic optimization.

An Evaluation of Ontology Exchange Languages for Bioinformatics
This paper reports on an effort among the authors to evaluate alternative ontology-exchange languages, and to recommend one or more languages for use within the larger bioinformatics community.
-
Boosted wrapper induction
We describe an algorithm that learns simple, low-coverage wrapper-like extraction patterns, which we then apply to conventional information extraction problems using boosting.

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…

An Ontology for Biological Function Based on Molecular Interactions
The article explores the notion of computing with function, and explains the importance of ontologies of function to bioinformatics.

Global Properties of the Metabolic Map of Escherichia coli
Here we present a computational analysis of the global properties of that network, which consists of 744 reactions that are catalyzed by 607 enzymes.
-
The EcoCyc and MetaCyc Databases
Both databases are queried using the Pathway Tools graphical user interface, which provides a wide variety of query operations and visualization tools.

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.
