Note to self about a possible project. This PLoS ONE paper: describes a method for inferring a hierarchy from a set of tags (and cites related work that is of interest). I've grabbed the code and data from http://hiertags-beta.elte.hu/home/ and put it on GitHub. Possible project Use Tibély et al. method (or others) on taxonomic names extracted from BHL text (or other) and see if we can reconstruct taxonomic classifications.

I've added a feature to my Biodiversity Heritage Library viewer that should help make sense of the names found on a page. Until now I've displayed them as a list of "tags", which ignores the relations among the names.

For fun I quickly programmed a little tool for bioGUID that makes use of Connotea's web api. When an article is displayed, the page loads a Javascript script that makes a call to a simple web service that looks up a reference in Connotea and displays a tag cloud if the reference is found.

My delicious tags as a Wordle. In my defense I've not had nearly enough coffee today.
