I am an adjunct prof at University of North Carolina Chapel Hill so when I stopped by yesterday for a business meeting I was informed that I had been lined up to give a talk to the students at 1pm. I had 20 minutes to prepare and assembled a mish-mash of information that might be of value to Citizen Chemists, those who might want to contribute to chemistry on the internet

      • Subset searching – choose from 200 data sources
      • Property searching
      • Searches are used in various ways by different types of chemists…
    • ChemSpider Searches
    • ChemSpider Searches
    • Antony Williams vs Identifiers Passport ID Dad, Tony, others SSN Green Card License 5 email addresses ChemSpiderman (blog, Twitter account, Facebook, Friendfeed) OpenID … .
    • Aspirin vs Chemical Identifiers
    • Aspirin names and synonyms
      • Text searches depend on correct association
      • 335 suggested identifiers for Aspirin just on PubChem!
      • Disambiguation dictionaries are necessary
    • The Final Search Strategy
    • All Those Names, One Structure
    • Connections Can Lead Anywhere
    • The InChI Identifier
    • Multiple Layers
    • InChIStrings Hash to InChIKeys
    • Oleoylethanolamine
    • Search Engine Dependencies
    • Search Engine Dependencies
    • Vancomycin
    • Vancomycin
      • Who will curate?
      • How would you clean such a large dataset?
    • Chemistry on the Internet
      • Much of the information is based on assertions and User Beware!
      • The Quality of information available is diverse and how does the user know what is and is not “correct”?
    • Caution! Question Everything!
    • Question Everything online: www.dhmo.org
    • Vancomycin on ChemSpider
    • Vancomycin

    • Where is ChemSpider Lacking?
      • ChemSpider is limited to “defined chemicals”. No support for:
        • Polymers
        • Minerals
        • Markush structures
      • ChemSpider is very dependent on InChIs
        • Stereochemistry around non-carbon centers

      • Curate ChemSpider data and link to us
      • Deposit your data with us
        • Structures
        • Spectra
        • Synthesis procedures
      • ChemSpider Synthesis is under development
    • People Make Change Happen
      • ChemSpider was a “hobby project”
      • Housed in a basement and running off three servers – one bought, two built
      • Sensitive to weather and power stability
      • Went live at ACS Spring 2007 in Chicago
      • ca. 6000 visitors a day, >50,000 transactions daily
    • Organizations Scale Innovation
