This document summarizes ChemSpider, a database containing over 28.5 million unique chemicals from over 400 data sources. ChemSpider aims to improve data quality and functionality by integrating data and enabling other platforms. It receives around 30,000 daily visits and over 500,000 unique monthly visitors. ChemSpider provides programmatic APIs and widgets to embed content. It also supports the semantic web by providing data in RDF format. ChemSpider works to support various audiences and natural products research. It contributes chemistry services, user interfaces, and acts as a "quality police" by checking data. ChemSpider also integrates with other projects and aims to build a chemical registration system and community data repository.

13. • 3-year knowledge management IMI project
• Integrating chemistry and biology data and delivering
using semantic web technologies
• Open source code, open data and open standards
• Academics, Pharma companies, Publishers….

14. ChemSpider Contributions
• The host of the chemistry services
– Supplier of “standardized” chemical data files
– Chemistry searching (structure, substructure etc)
– Provider of data in RDF format
– Curator and data quality checking
• Now building the Open PHACTS chemical
registration system

15. ChemSpider Contributions
• Supplier of chemistry UI components
• “Quality Police” for data checking
• Chemical Validation and Standardization Platform
• Nanopublications from RSC publications

16. • FP7 Initiative. PharmaSea: increasing value and flow in
the marine biodiscovery pipeline

17. PharmaSea
• Dereplication via ChemSpider
• Segregation of natural products datasets
• Analytical data algorithms & integration
– Mass spec searching – predicted fragmentation
– NMR feature searching – NMR prediction
– Computer-assisted structure elucidation

18. Integrate to instruments and software
• Integration to analytical instrumentation vendors
already in place
– Agilent, Bruker, Thermo, Waters
• Also, Cheminformatics vendors link to ChemSpider
– Accelrys, ACD/Labs, ChemAxon, iChemLabs, and…

19. Natural Products Updates
• Names hard, Structures
“Obvious”
• New content based on
monthly updates of the
database
• Click through to the Natural
Products Updates entry

20. National Chemical Database Service

21. Chemical Database
Service
• National Chemical Database Service
for UK Academics
• Integrating Commercial Databases
and Services
• Chemicals, analytical data,
prediction algorithms
• Development of data repository

22. Retrosynthetic Analysis

23. 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?

24. Community Repository for Data
• Funding agencies encourage sharing of data
• Increasing availability of “Open Data”
• Institutional repositories no specific domain
support
• Develop a community repository for chemistry
data – private, public, embargoed
• Provides data to develop models/algorithms

25. Community Repository for Data
• Automated depositions of data
• DOI’ed data objects for citation purposes
• A database of reference data, but validated by
the community
• National services feeding the repository –
crystallography, mass spectrometry
• Integrate to blogging tools for chemistry
• Integrate to Electronic Lab Notebooks as feeds

26. Model Building with Community Data
• Community data as a basis of model building
– Consume data from available databases, community
data, new publications and build predictive
algorithms for the community
– How many algorithms are reported and lost? How
much repeat work is done in the domain of
algorithmic development?

27. Recognition on
Data
IC50 Measurements for 62 substituted benzoxazoles

45. Rewards and Recognition
The First Step badge is
awarded when a user
submits (& has published)
their 1st CSSP article.
Congratulations! Your 1st CSSP article
has been published. Philosopher Lao
Tzu said “A journey of a thousand
miles begins with a single step”. In the
same way we hope that this will be
the first of many submissions that you
make to CSSP.
