Some quick notes on possibilities for text-mining BHL (in rough order of priority). Any text-mining would have to be robust to OCR errors.

Anyone who works with taxonomic databases is aware of the fact that they have errors. Some taxonomic databases are restricted in scope to a particular taxon in which one or more people have expertise, these then get aggregated into larger databases, which may in turn be aggregated by databases whose scope is global.

Just some random thoughts on creating searchable PDFs for article extracted from BHL.

In Arthur C. Clarke's short story The Nine Billion Names of God Tibetan monks hire two programmers to help them generate all the the possible names of God. The monks believe that the purpose of the Universe is to generate those names, once that goal is achieved the Universe will end.

As part of a project to build a tool to navigate through taxonomic names and classifications I've become interested in quick ways to compare classifications.

One visualisation method I keep coming back too is the treemap.

While exploring ways to visually compare classifications I came across the Australian snake name Demansia atra , and ended up reading a series of papers in the Bulletin of Zoological Nomenclature discussing the status of the name (more fun than it sounds, trust me). For example, Smith and Wallach Case 2920.

In response to Rutger Vos's question I've started to add GBIF taxon ids to the iPhylo Linkout website. If you've not come across iPhylo Linkout, it's a Semantic Mediawiki-based site were I maintain links between the NCBI taxonomy and other resources, such as Wikipedia and the BBC Nature Wildlife finder. For more background seePage, R. D. M. (2011). Linking NCBI to Wikipedia: a wiki-based approach. PLoS Currents, 3, RRN1228.

There's a recent thread on the Encyclopedia of Life concerning erroneous images for the crab Leptograpsus . This is a crab I used to chase around rooks on stormy west-coast beaches near Auckland, so I was a little surprised to see the EOL page for Leptograpsus looks like this:The name and classification is the crab, but the image is of a fish ( Lethrinus variegatus ). Perhaps at some point in aggregating the images the two

This post arose from an ongoing email conversation with Tony Rees about extracting and annotating taxonomic names. In BioStor I use the GBIF classification to display the taxonomic names found in the OCR text in the form of a tree.
