going a mile inchi by inchi : enabling online chemistry at chemspider
DESCRIPTION
The task of finding chemical information online can be daunting since even the most rudimentary query on Google can provide tens to hundreds of thousands of links to peruse. While there has been an increase in the number of online chemical structure databases there has not been a central online resource allowing integrated chemical structure-searching of chemistry databases, chemistry articles, patents and web pages, such as blogs and wikis, until now. ChemSpider provides a significant knowledge base and resource for chemists working in different domains. From the perspective of the InChI identifiers this project can be considered to be a success story since ChemSpider has used both for the development of the database and the provision of fast searching routines. ChemSpider has provided web services for both InChI generation and searching, leading to a proliferation of InChI in the web-based domain of chemistry. This talk will provide an update of ChemSpiders functionality.TRANSCRIPT
