ChemSpider is a free access online structure-based community for chemists to research data and information. The database of over 20 million chemical structures and associated data has been derived from depositions by well over a hundred contributing data sources including chemical vendors, commercial database providers, web-based scraping of data and individual scientists looking to share their information with the community. Text-mining and conversion of chemical names and identifiers to chemical structures has made an enormous contribution to the availability of diverse data on ChemSpider and includes contributions from patents, open access articles and various online resources. This presentation will provide an overview of the present state of development of this important public resource and review the processes and procedures for the harvesting, deposition and curation of large datasets derived via text-mining and conversion.
