	Representations of molecular pathways: an evaluation of SBML, PSI MI and BioPAX Bioinformatics, Vol. 21, No. 24.

Standards for representation of information about pathways are necessary for integration and analysis of data from various sources. Recently, a number of representation formats for pathway data, SBML, PSI MI and BioPAX, have been proposed. RESULTS: In this paper we compare these formats and evaluate them with respect to their underlying models, information content and possibilities for easy creation of tools. The evaluation shows that the main structure ...
	PAX of mind for pathway researchers. Drug discovery today, Vol. 10, No. 13. (1 July 2005), pp. 937-942. by J. S. Luciano posted to biopax data dt format pathway representation by wnpx on 2006-11-17 15:55:21 along with 4 people allysonlister balajis dullhunk lenov Abstract Copy My Attachments My Copy Abstract Scientists seeking to understand the inner workings of cells have access to a multitude of pathway data resources. However, the representations of pathway data within these resources are not consistent or interchangeable. To facilitate easy information retrieval from a wide variety of pathway resources, such as signal transduction, gene regulation, molecular interaction and metabolic pathway databases, a broad effort in the biopathways community called BioPAX was formed. New biological pathway software applications built using the BioPAX standard will be able to ...
	Module networks: identifying regulatory modules and their condition-specific regulators from gene expression data. Nature genetics, Vol. 34, No. 2.

We present a probabilistic method for identifying regulatory modules from gene expression data. Our procedure identifies modules of coregulated genes, their regulators and the conditions under which regulation occurs, generating testable hypotheses in the form 'regulator X regulates module Y under conditions W'. We applied the method to a Saccharomyces cerevisiae expression data set, showing its ability to identify ...
	Dynamic Multi-Dimensional Models for Text Warehouses by Maria Z. Bleyberg posted to data database multidimensional natlang warehouse by wnpx on 2006-01-29 19:43:55 Abstract Copy My Attachments My Copy Abstract In this paper, we introduce a dynamic multidimensional model, which is suitable for building text warehouses. The dimensions are atomic semantic categories embedded in a familiar taxonomy. This approach to text warehouses requires a large number of dimensions, some of which may be not known in advance. Central to the dynamic multi-dimensional model is the meta-snowflake schema, which is a snowflake schema with an index table. The index table contains metadata on dimensions consisting of... ...
	Why is the Star Schema a Good Data Warehouse Design? by Mark Levene, George Loizou posted to data database multidimensional schema star by wnpx on 2006-01-29 19:43:17 along with 1 person danchicu Abstract Copy My Attachments My Copy Abstract Database design for data warehouses is based on the notion of the snowflake schema and its important special case, the star schema. The snowflake schema represents a dimensional model which is composed of a central fact table and a set of constituent dimension tables which can be further broken up into subdimension tables. We formalise the concept of a snowflake schema in terms of an acyclic database schema whose join tree satisfies certain structural properties. We then define a normal form... ...
