Identifying and Segmenting Human-Motion for Mobile Robot Navigation using alignment errors
This paper presents a new human-motion identification and segmentation algorithm from moving cameras. The algorithm is based on alignment error between pairs of moving object images. Pairs of object images…

Mixed-Initiative Issues for a Personalized Time Management Assistant
This paper explores the mixed-initiative issues arising in the Personalized Time Manager (PTIME) system. PTIME is a persistent assistant that builds on our previous work on a personalized calendar agent.

A Portable Process Language
In this paper, we report on a process language, PPL, that we have designed to serve as a bridge between a representation designed for execution and a representation designed for…

MetaCyc and AraCyc. Metabolic Pathway Databases for Plant Research
In conjunction with the Pathway Tools software, MetaCyc can be used to computationally predict the metabolic pathway complement of an annotated genome.

A Personalized Time Management Assistant
This paper presents ongoing work to build the Personalized Time Manager (PTIME) system, a persistent assistant that builds on our previous work on a personalized calendar agent.

Execution Monitoring and Replanning with Incremental and Collaborative Scheduling
We describe the Flight Manager Assistant (FMA), a prototype system, designed to support real-time management of airlift operations at the USAF Air Mobility Command (AMC).

Querying and Computing with BioCyc Databases
We describe multiple methods for accessing and querying the complex and integrated cellular data in the BioCyc family of databases.

The Role of Higher-Order Constructs in the Inexact Matching of Semantic Graphs
This paper reports the results of an experimental analysis of higher-order constructs in graphical patterns and their effect on pattern matching efficiency.

Expansion of the BioCyc Collection of Pathway/Genome Databases to 160 Genomes
This paper discusses the computational methodology by which the BioCyc collection has been expanded, and presents an aggregate analysis of the collection that includes the range of number of pathways…

Genome Annotation Errors in Pathway Databases Due to Semantic Ambiguity in Partial EC Numbers
We report on a new type of systematic annotation error in genome and pathway databases that results from the misinterpretation of partial Enzyme Commission (EC) numbers such as ‘1.1.1.-’.

New experiments in distributional representations of synonymy
We generated a TOEFL-like test using WordNet, containing thousands of questions and composed only of words occurring with sufficient corpus frequency to support sound distributional comparisons.
