We Have …Too Much Data!!!

Page 3: RSC ChemSpider for students

The World of Online Chemistry Property databases Compound aggregators Screening assay results Scientific publications Encyclopedic articles (Wikipedia) Metabolic pathway databases ADME/Tox data – eTOX for example Blogs/Wikis and Open Notebook Science Contributing Open Source code to projects

ChemSpider

The Free Chemical Database

A central hub for chemists to source information >28 million unique chemical records Aggregated from >400 data sources Chemicals, spectra, CIF files, movies, images,

podcasts, links to patents, publications, predictions

A central hub for chemists to deposit & curate data

We Want to Answer Questions

Questions a chemist might ask… What is the melting point of n-heptanol? What is the chemical structure of Xanax? Chemically, what is phenolphthalein? What are the stereocenters of cholesterol? Where can I find publications about xylene? What are the different trade names for Ketoconazole? What is the NMR spectrum of Aspirin? What are the safety handling issues for Thymol Blue?

Conclusions ChemSpider is a FREE resource for the community Grows daily with new data – do you have any to

share? Concerned about data quality! YOU SHOULD BE! Crowdsourced and algorithmic curation is working API is available to access data – any informatics

people want access??

If you want hands on training I can come and give it
