In recent years, in parallel with the general broad trend of information proliferation, many tens of public chemical databases have been created and made available using internet technologies. In many cases fluent data exchange has occurred between these various databases as they source information from one another. While this has the advantages of linking together multiple data sources the results also include the proliferation of errors across the various databases. The lack of a public authority to resolve such errors significantly affects the quality of freely accessible chemical information. While ChemSpider has previously allowed a crowdsourcing approach to curation efforts have now migrated to addressing this problem using a "federated resolver" approach. This presentation will report on our work in this area.
