Our access to scientific information has changed in ways that were hardly imagined even by the early pioneers of the internet. The immense quantities of data and the array of tools available to search and analyze online content continues to expand while the pace of change does not appear to be slowing. ChemSpider is one of the chemistry community’s primary online public compound databases. Containing tens of millions of chemical compounds and its associated data ChemSpider serves data tens of thousands of chemists every day and it serves as the foundation for many important international projects to integrate chemistry and biology data, facilitate drug discovery efforts and help to identify new chemicals from under the ocean. This presentation will provide an overview of the expanding reach of the ChemSpider platform and the nature of the solutions that it helps to enable. We will also discuss the possibilities it offers in the domain of crowdsourcing and open data sharing. The future of scientific information and communication will be underpinned by these efforts, influenced by increasing participation from the scientific community and facilitated collaboration and ultimately accelerate scientific progress.

  1. 1. eScience Resources for the Chemistry Community from the Royal Society of Chemistry Antony Williams NCSU, College of Textiles October 2nd 2013
  2. 2. We Have …Too Much Data!!!
  3. 3. 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
  4. 4. e-Science and Primary Data • How much data generated in a lab, that COULD go public, is lost forever?
  5. 5. e-Science and Primary Data • How much data generated in a lab, that COULD go public, is lost forever? • Public Domain reference databases of value? – Syntheses – Properties – Spectra – CIFs – Images
  6. 6. e-Science and Primary Data • How much data generated in a lab, that COULD go public, is lost forever? • Public Domain reference databases of value? – Syntheses – Properties – Spectra – CIFs – Images • Much of chemistry is chemical structure-based – where and how could we host these data?
  7. 7. RSC’s ChemSpider
  8. 8. ChemSpider • >29 million unique chemicals from >500 data sources • Focus on improving data quality, enhancing functionality, integrating and enabling
  9. 9. Crowdsourced “Annotations” • Users can add – Descriptions/Syntheses/Commentaries – Links to PubMed articles – Links to articles via DOIs – Add spectral data – Add Crystallographic Information Files – Add photos – Add MP3 files – Add Videos
  10. 10. Spectra
  11. 11. Chemistry Data online are messy • We have inherited errors • All public compound databases have errors • “Incorrect” structures – assertions, timelines etc • “Incorrect” names associated with structures • Properties • Links • Publications • ENORMOUS CHALLENGE
  12. 12. Crowdsourced Curation • Crowd-sourced curation: identify/tag errors, edit names, synonyms, identify records to deprecate

  15. 15. “Curate” Identifiers
  16. 16. “Curate” Identifiers
  17. 17. Validated Name-Structure Dictionaries • Chemical name dictionaries are used for: • Text-mining (publications, patents) – Used to index PubMed and link to Google Patents • Linking to other databases – think Biology! – When structures are not available drug names link • Searching the web – Names link to structures link to InChIs
  18. 18. I want to know about “Vincristine”
  19. 19. Vincristine: Identifiers and Properties
  20. 20. Vincristine: Vendors and Sources Linked by Structure

  32. 32. Some usage statistics • ca. 200 visitors at any one time, ~30,000 visits per day • Mar 4-Apr 3, 2013 – Visits = 731,656 – Unique Visitors = 527,008 • Independent servers to support other projects
  33. 33. Publications - a summary of work • Scientific publications are a summary of work – Is all work reported? – How much science is lost to pruning? – What of value sits in notebooks and is lost? • How much data is lost? – How many compounds never reported? – How many syntheses fail or succeed? – How many characterization measurements?
  34. 34. About Me…as a Chemist • I’ve performed a few dozen chemical syntheses • I’ve run thousands of analytical spectra • I’ve generated thousands of NMR assignments • I’ve probably published <5% of all work • Most of it has been lost • But things can be different today…. • But it still needs to be associated with me…
