===Intellectual Merit===
The project will develop a methodology that exploits the wealth of annotation knowledge,
notably Gene Ontology (GO) and Plant Ontology (PO) annotations of Arabidopsis genes.
Motivated by the availability of rich and as yet insufficiently tapped  collections of gene annotations,
the project aims to facilitate the discovery of hidden knowledge that could be the basis of further
scientific research.  The methodology will extract patterns of interest from annotation graphs (pattern
discovery). Literature-based methods will extract sentences that validate the  biological meaning
underlying these patterns (pattern validation).
To demonstrate the methodology, the PattArAn tool (Patterns in Arabidopsis Annotations) will be
customized for Arabidopsis. PattArAn will provide the user with a graphical presentation of patterns
of Arabidopsis genes and associated GO and PO CV terms. Graph data mining techniques and
efficient algorithmic solutions to identify dense subgraphs (DSG) and to perform graph
summarization (GS) will be developed. Algorithms to mine the literature for  relevant sentences for
an extracted pattern (referred to as the imprint) will be developed. PattArAn will enable iterative
exploration and will incorporate allied steps such as consulting gene function prediction.
The project will involve collaboration with biologists for building and refining annotation graphs, and
validating patterns to ensure relevance to their research.

also be used to bootstrap an annotation database  for other plant species.  The 
project will offer significant research and educational experiences for graduate 
students (University of Maryland and Iowa) and undergraduate students (St.

Intellectual Merit

The project will develop a methodology that exploits the wealth of annotation knowledge, 
notably Gene Ontology (GO) and Plant Ontology (PO) annotations of Arabidopsis genes.

Motivated by the availability of rich and as yet insufficiently tapped  collections of gene annotations, 
the project aims to facilitate the discovery of hidden knowledge that could be the basis of further 
scientific research.  The methodology will extract patterns of interest from annotation graphs (pattern 
discovery). Literature-based methods will extract sentences that validate the  biological meaning 
underlying these patterns (pattern validation). 

To demonstrate the methodology, the PattArAn tool (Patterns in Arabidopsis Annotations) will be 
customized for Arabidopsis. PattArAn will provide the user with a graphical presentation of patterns 
of Arabidopsis genes and associated GO and PO CV terms. Graph data mining techniques and 
efficient algorithmic solutions to identify dense subgraphs (DSG) and to perform graph 
summarization (GS) will be developed. Algorithms to mine the literature for  relevant sentences for 
an extracted pattern (referred to as the imprint) will be developed. PattArAn will enable iterative 
exploration and will incorporate allied steps such as consulting gene function prediction. 
The project will involve collaboration with biologists for building and refining annotation graphs, and 
validating patterns to ensure relevance to their research.

Broader Impact

This project brings broad contributions to the Arabidopsis thaliana community; 
PattArAn may assist Arabidopsis curators to manage GO-PO annotations.  It can 
also be used to bootstrap an annotation database  for other plant species.  The  
project will offer significant research and educational experiences for graduate  
students (University of Maryland and Iowa) and undergraduate students (St. 
Bonaventure University).  Team members will continue to mentor women and students 
from under-represented communities, participate in outreach activities, lead a  
Journal Club, etc. The outcomes from this research project will be disseminated  
via biology and bioinformatics venues.
