Google knows how many species there are. More significantly, it knows what I mean when I type in "how many species are there". Wouldn't it be nice to be able to do this with biodiversity databases? For example, how many species of insect are found in Fiji? How would you answer this question? I guess you'd Google it, looking for a paper.

Last week I attended the Wikipedia Science Conference (hashtag: #wikisci) at the Wellcome Trust in London. it was an interesting two days of talks and discussion. Below are a few random notes on topics that caught my eye. What is Wikidata? A recurring theme was the emergence of Wikidata, although it never really seemed clear what role Wikidata saw for itself.

Over the weekend, out of the blue, Dan Whaley commented on an earlier blog post of mine (Altmetrics, Disqus, GBIF, JSTOR, and annotating biodiversity data. Dan is the project lead for hypothes.is, a tool to annotate web pages.

A little over a week ago I was at the 6th International Barcode of Life Conference, held at Guelph, Canada. It was my first barcoding conference, and was quite an experience. Here are a few random thoughts. Attendees It was striking how diverse the conference crowd was. Apart from a few ageing systematists (including veterans of the cladistics wars), most people were young(ish), and from all over the world.

Yet another barely thought out project, although this one has some crude code. If some 16,000 new taxonomic names are published each year, then that is roughly 40 per day. We don't have a single place that aggregates these, so any major biodiversity projects is by definition out of date. GBIF itself hasn't had an update list of fungi or plant names for several years, and at present doesn't have an up to date list of animal names.

I need more time to sketch this out fully, but I think a case can be made for a taxonomy-centric (or, perhaps more usefully, a biodiversity-centric) clone of PubMed Central. Why? We already have PubMed Central, and a European version Europe PubMed Central, and the content of Open Access journals such as ZooKeys appears in both, so, again, why?

One of the limitations of the Biodiversity Heritage Library (BHL) is that, unlike say Google Books, its search functions are limited to searching metadata (e.g., book and article titles) and taxonomic names. It doesn't support full-text search, by which I mean you can't just type in the name of a locality, specimen code, or a phrase and expect to get back much in the way of results.

One of the less glamorous but necessary tasks of data cleaning is mapping "strings to things", that is, taking strings such as "George A. Boulenger" and mapping them to identifiers, such as ISNI: 0000 0001 0888 841X. In case of authors such as George Boulenger, one way to do this would be through Wikipedia, which has entries for many scientists, often linked to identifiers for those people (see the bottom of the Wikipedia page for George A.

Following on from Testing the GBIF taxonomy with the graph database Neo4J I've added a more complex test that relies on linking taxa to names. In this case I've picked some legume genera ( Coursetia and Poissonia ) where there have been frequent changes of name.

Imagine a web site where researchers can go, log in (easily) and get a list of all the species they have described (with pretty pictures and, say, GBIF map), and a list of all DNA sequences/barcodes (if any) that they've published. Imagine that this is displayed in a colourful way (e.g., badges), and the results tweeted with the hastag #itaxonomist.
