Quick note to self, having stumbled on the Wikipedia page on transitive reduction. Given a graph like this:the transitive reduction is:Note that the original graph has an edge a -&gt; d, but this is absent after the reduction because we can get from a to d via b (or c). What's the point?

No, not taxonomy the discipline (although I've given a talk asking this question), but taxonomy.zoology.gla.ac.uk, my long-running web server hosting such venerable software projects as TreeView, NDE, and GeneTree, along with my home page.A series of power cuts in my building while I was away finally did for my ancient Sun Sparcstation5, running the CERN web server (yes, it's

The first pPod workshop happened last month at NESCent, and some of the presentations are online on the pPod Wiki. Although I'm a "consultant" I couldn't be there, which is a pity because it looks to have been an interesting meeting. When pPod was first announced I blogged some of my own thoughts on phylogenetics databases.

The latest version of the David and Wayne Maddison's Cartographer module for their program Mesquite can export KML files for Google Earth. They graciously acknowledge my crude efforts in this direction, and  Bill Piel's work -- he really started this whole thing rolling.So, those of you inspired to try your hand at Google Earth trees, and who were frustrated by the lack of tools should grab a copy of Mesquite and take it for a spin.

Mesquite does Google Earth files

In an earlier post I described the TBMap database (doi:10.1186/1471-2105-8-158), which contains a mapping of TreeBASE taxon names onto names in other databases. While this is one step towards making it easier to query TreeBASE, what I'd really like is to link the data in TreeBASE to sources such as GenBank and specimen databases.

I would prefer to avoid Microsoft-bashing, but today I've spent time trying to get my tree viewer to work under Internet Explorer 6 and 7, and it's hell. Here are the problems I've had to deal with:

For the "to do" list, expand-ahead browsing looks like a useful approach to build upon PygmyBrowse (see my live demo). The approach is described in "Expand-Ahead: A Space-Filling Strategy for Browsing Trees" by McGuffin et al. (doi:10.1109/INFOVIS.2004.21, PDF also here).There is a video on Ravin Balakrishnan's site, which is an AVI file that I haven't bee able to coerce my Mac into playing, hence I've posted it on YouTube.

OK, time to put my money where my mouth is. Here's a first stab at displaying big trees in a browser. Not terribly sophisticated, but reasonably fast. Take a look at Big Trees.

 Approach

Given a tree I simply draw it in a predetermined area (in these examples 400 x 600 pixels). If there are more leaves than can be drawn without overlapping I simply cull the leaf labels.

One of the striking pictures in Tamara Munzner et al.'s paper "TreeJuxtaposer: Scalable Tree Comparison using Focus+Context with Guaranteed Visibility" (doi:10.1145/882262.882291, also available here) is that of a biologist struggling to visualise a large phylogeny.

Based on my recent experience developing an OpenURL service (described here, here, and here), linking this to a reference parser and AJAX tool (see David Shorthouse's description of how he did this), and thoughts on XMP, maybe it's time to try and articulate how this could be put together to make taxonomic literature more accessible.Details below, but basically I think we could make major progress by:Creating an OpenURL service that knows about

Added the Biodiversity Heritage Library blog to my links on my blog, then noticed that BHL have disabled comments. So, we can view their progress, but can't leave comments. Sigh, I wonder whether BHL has quite grasped that one of the best uses of a blog is to interact with the people who leave comments, in other words, have a conversation.

postgenomic is a great way to keep up with science blogs. For example, searching for encyclopedia of life pulls up all sorts of interesting posts.

In the spirit of "release early, release often", a preliminary version of the TreeBASE name mapping project is now online at TBMap. It's a bit crude, the graphs look awful because they're generated on the fly on a Linux box using GraphViz, but you'll get the idea. I'll try and tidy it up and add a few more visuals to it next week after the EOL Informatics meeting at Woods Hole. There are also some missing mappings to add to the database.

My Taxonomic Search Engine is back online (mostly). This tool to search multiple databases for scientific names was another casualty of hacking. Having been developed under PHP 4, it needed some work to play nice with PHP 5. The changes were minor, and mainly concerned changes in code involving XPath and XSLT. I've commited these changes to SourceForge.

Taxonomic Search Engine back online

Not a huge fan of IE, but this post on David Patten's blog nicely illustrates the ease of use of A9's OpenSearch with IE 7. I'd previously played with OpenSearch as a quick way to integrate biodiversity sources, and put together a couple that have been registered with A9 (search for "taxonomy" and you'll find them). It's essentially adding a few tags to RSS or Atom feeds, coupled with a simple way to describe the search engine.Perhaps it's time

A quick Google found this Firefox extension for turning built-in SVG on and off, posted on or maybe something uplifting.Really useful little extension, because Firefox SVG support is actually pretty awful very good. (Just discovered that FireFox couldn't handle my original SVG, but if I put in the namespaces as attributes of the

tag, everything worked fine.

Continuing the theme of visualising phylogenies, one thing which strikes me is the parallel between genome browsers that display annotation "tracks" (such as the UCSC Genome Browser) and illustrations of "chronograms" with geological periods and accompanying data, such as sea levels, isotope levels, etc. In my haste I couldn't find an example with a sea-level track, but I know they exist. The chronogram at right comes from Steppan et al.

I've updated my extension to resolve LSIDs in Firefox so that it works with version 1.5.0.1 (the most recent version of Firefox). The extension is available from Mozdev. It may take a little while for the mirrors to update with the new version, so if you get a "404" when trying to download, you may need to come back later.IBM's LSID project have their own Firefox extension LSID Launchpad for Firefox, which is a lot slicker than mine.

One of the potentially powerful features of TreeBASE II is availability of a RDF version of a study. This means that, in principle, one could take the RDF for a TreeBASE study, combine it with RDF from other sources, and generate a richer view of a particular study.

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.

The following is a guest post by Bob Mesibov. Do you know the party game "Telephone", also known as "Chinese Whispers"? The first player whispers a message in the ear of the next player, who passes the message in the same way to a third player, and so on. When the last player has heard the whispered message, the starting and finishing versions of the message are spoken out loud. The two versions are rarely the same.

GBIF is running its Ebbe Nielsen Challenge for the third successive year. This year the title is Liberating species records from open data repositories for scientific discovery and reuse. To quote from the Challenge background on Devpost:  In essence, the 2017 Challenge is to develop tools to discover these biodiversity-relevant datasets, and make them available to GBIF.

At present BioStor provides a simple display of an article extracted from BHL. You get the page images, and sometimes a map and an altmetric "donut". But we can do better than this. For example, I'm starting to experiment with displaying a list of literature cited by the article.

New feature for BioStor: extracting literature cited from OCR text

Given that Wikipedia, Wikidata, and the Biodiversity Heritage Library (BHL) all share the goal of making information free, open, and accessible, there seems to be a lot of potential for useful collaboration. Below I sketch out some ideas.

 BHL as a source of references for Wikipedia

Wikipedia likes to have sources cited to support claims in its articles. BHL has a lot of articles that could be cited by Wikipedia articles.

Some notes to self about future directions for the "million DNA barcodes map" http://iphylo.org/~rpage/bold-map/. At the moment we have an interactive map that we can pan and zoom, and click on a marker to get a list of one or more barcodes at the location. We can also filter by major taxonomic group. Here are some ideas on what could be next.

Bibliographic coupling is a term coined by Kessler (doi:10.1002/asi.5090140103) in 1963 as a measure of similarity between documents. If two documents, A and B, cite a third, C, then A and B are coupled.I'm interested in extending this to data, such as DNA sequences and specimens. In part this is because within the challenge dataset I'm finding cases where authors cite data, but not the paper publishing the data.

In case I forget how to do this, and as an example of how easy it is to get sucked into a black hole of programming micro-details, I spent a hour or more trying to figure out how to handle Japanese characters.I'm building a database of publications linked to taxonomic names, and I'm interested in linking to electronic versions of those publications.

One thing about ChatGPT is it has opened my eyes to some concepts I was dimly aware of but am only now beginning to fully appreciate.

Indeed, ChatGPT itself now supports this using plugins.

Taxonomic treatments have come up in various discussions I'm involved in, and I'm curious as to whether they are actually being used, in particular, whether they are actually being cited. Consider the following quote:  "Traditional" academic citation is from article to article.

uBioRSS: Tracking taxonomic literature using RSS

Aggregating, Tagging and Integrating Biodiversity Research

Over a decade ago RSS (RDF Site Summary or Really Simple Syndication) was attracting a lot of interest as a way to integrate data across various websites. Many science publishers would provide a list of their latest articles in XML in one of three flavours of RSS (RDF, RSS, Atom). This led to tools such as uBioRSS [1] and my own e-Biosphere Challenge: visualising biodiversity digitisation in real time.

This is a guest post by Tony Rees. It would be difficult to encounter a scientist, or anyone interested in science, who is not familiar with the microscope, a tool for making objects visible that are otherwise too small to be properly seen by the unaided eye, or to reveal otherwise invisible fine detail in larger objects.

I've made Species Cite live. This is a web site I've been working on with the GBIF Challenge as a notional deadline so I'll actually get something out the door. "Species Cite" takes as its inspiration the suggestion that citing original taxonomic descriptions (and subsequent revisions) would increase citation metrics for taxonomists, and give them the credit they deserve.

This is just some random notes on an “ideal” taxonomic journal, inspired in part by some recent discussions on “turbo-taxonomy” (e.g., https://doi.org/10.3897/zookeys.1087.76720 and https://doi.org/10.1186/1742-9994-10-15), and also examples such as the Australian Journal of Taxonomy https://doi.org/10.54102/ajt.qxi3r which seems well-intentioned but limited.

Quick notes on "taxon concepts". In order to navigate through taxon names I plan to have at least one taxonomic classification in BioNames. GBIF makes the most sense at this stage. The model I'm adopting is that the classification is a graph where nodes have the id used by the external database (in this case GBIF). Each node has one or more names attached, and where possible the names are linked to the original description.

BioNames update - taxon concepts

As part of the discussion on whether legacy biodiversity literature matters a graph from the following paper came up:So, why is the Sarkar et al. graph bogus? Here is their graph (Fig. 3) for animals:This is the number of new animal species described each year, estimated by parsing taxonomic names and extracting the date in the taxonomic authority. There are two prominent "spikes" which are worrying.

Note to self. The challenge of finding specimen citations in papers keeps coming around. It seems that this is basically the same problem as finding citations to papers, and can be approached in much the same way. If you want to build a database of reference from scratch, one way is to scrape citations from papers (e.g., from the "literature cited" section), convert those strings into structured data, and add those to your database.

that I alluded to earlier has been accepted for publication. I've put a preprint up at Nature Preceding (hdl:10101/npre.2008.1760.1). The final version will appear in print later this year.

Biodiversity informatics: the challenge of linking data and the role of shared identifiers

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.

The GBIF classification is broken — how do we fix it?

Not really a blog post, more a note to self. If I ever did get around to writing a book again, I think

 
 Scripting Life
 

would be a great title.

Tony Rees commented on my recent post Ten years and a million links. I’ve responded to some of his comments, but I think the bigger question deserves more space, hence this blog post. Tony’s comment {#tony’s-comment} My response I think there are several ways to approach this.

Given that the Twitter stream tagged #vizbi will fade away soon, I've grabbed most of the links I tweeted during VIZBI 2011 and have put them here.

I'm trying to get my head around the data model used by ZooBank to store taxonomic names. To do this, I've built a graph for the species

I attended the TDWG-GUID workshop on Global Unique Indenitifers (GUIDs) held at NESCent, which has issued a report. Essentially, the aim of this work is to deploy globally unique identifiers for digital objects in biodiversity informatics, such as taxon names, specimen records, images, etc. The workshop settled on LSIDs (Life Science Identifiers), which is a sensible choice.

Globally Unique Identifiers

Comments by David Marjanović elsewhere on this blog (here and here) about TreeBASE, classification and Phylocode have prompted me to write a little bit about why I'm underwhelmed by the Phylocode. Suppose I have the question:How do I answer this? Well, my approach is to do the following. Firstly, I attempt to map every name in TreeBASE onto a name in an external database, such as NCBI Taxonomy, uBio, etc.

Some good news! pPOD, a  NSF-funded project on integrating data from AToL (A Tree of Life) projects has been funded. Val Tannen (right) is the co-ordinating PI. I'm a consultant, which means more opportunities to mouth-off about phylogenetic data and databases (for earlier examples see TreeBASE rocks, TreeBASE talk at CIPRES, and Towards the ToL database - some visions).The project is called pPOD, and has a wiki.

Recently I've been thinking about the best ways to make article-level metadata from BioStor more widely available. For example, for someone visiting the BHL site there is no easy way to find articles, which are the basic unit for much of the scientific literature. How hard would it be to add articles to BHL?
