The Challenge of Constructing, Classifying, and Representing Metabolic Pathways
This review describes the criteria that need to be considered, and the rules that have been developed by MetaCyc curators as they make decisions regarding the representation and classification of…

Extracting Spoken and Acoustic Concepts for Multimedia Event Detection
In this paper, we explore using acoustic concepts and spoken concepts extracted via audio segmentation/recognition and speech recognition respectively for Multimedia Event Detection (MED).
-
Computing Minimal Nutrient Sets from Metabolic Networks Via Linear Constraint Solving
We present a method for computationally determining alternative growth media for an organism based on its metabolic network and transporter complement.
-
A Systematic Comparison of the MetaCyc and Kegg Pathway Databases
We present a comparison of the compound, reaction, and pathway content of MetaCyc version 16.0 and a KEGG version downloaded on Feb-27-2012...

Sparse Conditional Mixture Model: Late Fusion with Missing Scores for Multimedia Event Detection
We present the Sparse Conditional Mixture Model (SCMM) which models only the observed detection scores for each example, thereby avoiding making any assumptions about the distributions of the scores that…

Conceptual Models of Structure and Function
We report our achievements in creating conceptual, multidimensional models of biological structure and function out of the linear text of an introductory biology textbook.

Data Mining in the Metacyc Family of Pathway Databases
The MetaCyc family of pathway databases consists of thousands of databases that were derived through computational inference of metabolic pathways from the MetaCyc pathway/genome database (PGDB).

KB_Bio_101: A challenge for OWL Reasoners
We describe the axiomatic content of a biology knowledge base that poses both theoretical and empirical challenges for OWL reasoning.

Dead End Metabolites — Defining the Known Unknowns of the E. coli Metabolic Network
We have analysed the occurrence of dead end metabolites within the database – these are metabolites which lack the requisite reactions (either metabolic or transport) that would account for their…
