EcoCyc: Encyclopedia of Escherichia coli genes and metabolism
The encyclopedia of Escherichia coli genes and metabolism (EcoCyc) is a database that combines information about the genome and the intermediary metabolism of E.coli .
-
Metabolic Databases
This article will describe some of the uses of these databases and then provide descriptions of the metabolic databases available.

Adaptive Process Management: An AI Perspective
In an effort to encourage the exchange of ideas, this paper explores how techniques from intelligent reactive control might be leveraged to provide adaptivity within workflow technologies, while also acknowledging…

Automatic Detection of Discourse Structure for Speech Recognition and Understanding
We describe a new approach for statistical modeling and detection of discourse structure for natural conversational speech. Our model is based on 42 `Dialog Acts' (DAs), (question, answer, backchannel, agreement,…
-
Using Information Extraction to Improve Information Retrieval
The authors describe an approach to applying a particular kind of Natural Language Processing NLP system to the TREC routing task in Information Retrieval IR.

Speech: A Privileged Modality
In this article, we use our interaction model to demonstrate that during multimodal fusion, speech should be a privileged modality, driving the interpretation of a query, and that in certain…
-
HMM State Clustering Across Allophone Class Boundaries
We present a novel approach to hidden Markov model (HMM) state clustering based on the use of broad phone classes and an allophone class entropy measure. Our algorithm allows clustering…
-
A Study of Multilingual Speech Recognition
This paper describes our work in developing multilingual (Swedish and English) speech recognition systems in the ATIS domain. The acoustic component of the multilingual systems is realized through sharing Gaussian…

Automatic Pronunciation Scoring of Specific Phone Segments for Language Instruction
The aim of the work described in this paper is to develop methods for automatically assessing the pronunciation quality of specific phone segments uttered by students learning a foreign language.
-
A Prosody-Only Decision-Tree Model for Disfluency Detection
We have developed a disfluency detection method using decision tree classifiers that use only local and automatically extracted prosodic features. Because the model doesn't rely on lexical information, it is…

Diagrammatic Methods for Deriving and Relating Temporal Neural Network Algorithms
We present an alternative approach based on a set of simple block diagram manipulation rules. The approach provides a common framework to derive popular algorithms including backpropagation and backpropagation-through-time, without…
