Update on WiChempedia

Antony Williams, WiChempedia Very Early Beta is Released Using New ChemSpider Dedicated Website Approach, ChemSpider Blog, April 15, 2008.

I blogged previously about our intention to build a structure/substructure searchable version of Wikipedia. We declared we would call it WiChempedia. Since rolling out the new website we have had the ability to provide access to subsets of data (See Molecule of the Day and Molbank as two examples). With this newfound ability it became easier to rollout WiChempedia and the first version is now available at

The difference between ChemSpider and WiChempedia, for now, is the presence of the first paragraph of the Wikipedia text on the WiChempedia site and a link out to the original article on Wikipedia. An example is shown below. Notice the link to the GNU free documentation license .

Hopefully we will receive feedback on the site quite quickly and get it out of beta at speed so please do let your colleagues know about it. We will design a new logo header shortly and we are aware that some minor types of the data resulting from the scraping process have slipped in so we will resolve those too. An example of how much information is starting to be populated can be seen by looking at the record for Cocaine here. Here you will see the Wiki first paragraph content, a link out to a GC run on the Phenomenex website, a series of validated identifiers and an IR spectrum. The content continues to expand as we source more information

I also point you to another implementation of a Wikipedia chemistry system,, that you might be interested in reviewing.
