The Predictive Toxicology Challenge 2000-2001

A Workshop at the 5th European Conference on Principles and Practice of Knowledge Discovery in Databases (PKDD 2001), September 3 - 7, 2001, Freiburg, Germany

Background

The purpose of this workshop is to discuss the results and submissions from the Predictive Toxicology Challenge 2000-2001. The present Predictive Toxicology Challenge is the successor of an earlier one announced at the International Joint Conference on AI 1997 conference. Both competitions were inspired by the NIEHS Predictive-Toxicology Evaluation Project, which involved contributions from human experts, expert systems, experimental techniques and data driven methods. 

The Predictive Toxicology Challenge (PTC) 2000-2001

The Challenge is to obtain models that predict the outcome of biological tests for the carcinogenicity of chemicals using information related to chemical structure only. Details, including datasets and instructions for submissions, can be found on the PTC website.

Workshop Organization

This workshop shall give all participants of the Predictive Toxicology Challenge the opportunity to present and discuss the submissions. Short presentations can cover methodological details of PTC submissions or aspects of Predictive Toxicology with general relevance. Participants interested in an oral presentation should submit an extended abstract, no longer than 2000 words, until July 20, 2001 to helma@informatik.uni-freiburg.de and register for the ECML/PKDD 2001 Conference. The collection of abstracts will be published as Workshop proceedings, further dissemination in a special issue of a journal will be discussed at the workshop. Acceptable abstract formats are HTML, Postscript and PDF. A large part of the workshop will be devoted to discussions about issues which will arise during the evaluation of the PTC submissions.
