New paper: "Integration among databases and data sets to support productive nanotechnology: Challenges and recommendations"

The U.S.A and European nanosafety communities have a longstanding history of collaboration. On both sides there are working groups, NanoWG and WG-F (previously called WG4) of the NanoSafety Cluster. I have been chair of WG4 for about three years and still active in the group, though in the past half year, without dedicated funding, less active. That is already changing again with the imminent start of the NanoCommons project. 1 minute read

Two conference proceedings: nanopublications and Scholia

It takes effort to move scholarly publishing forward. And the traditional publishers have not all shown to be good at that: we’re still basically stuck with machine-broken channels like PDFs and ReadCubes. They seem to all love text mining, but only if they can do it themselves. 1 minute read

The SWAT4LS poster about eNanoMapper

SWAT4LS was once again a great meeting. I doubt I will find time soon enough to write up notes, but at least I can post the eNanoMapper poster I presented, which is available from F1000Research: less than 1 minute read

New Paper: "Using the Semantic Web for Rapid Integration of WikiPathways with Other Biological Online Data Resources"

Andra Waagmeester published a paper on his work on a semantic web version of the WikiPathways (doi:10.1371/journal.pcbi.1004989). The paper outlines the design decisions, shows the SPARQL endpoint, and several examples SPARQL queries. These include federates queries, like a mashup with DisGeNET (doi:10.1093/database/bav028) and EMBL-EBI’s Expression Atlas. That results in nice visualisations like this: 2 minute read

Migrating pKa data from DrugMet to Wikidata

In 2010 Samuel Lampa and I started a pet project: collecting pKa data: he was working on RDF extension of MediaWiki and I like consuming RDF data. We started DrugMet. When you read this post, this MediaWiki installation may already be down, which is why I am migrating the data to Wikidata. Why? Because data curation takes effort, I like to play with Wikidata (see this H2020 proposal by Daniel Mietchen et al.), I like Open Data, and it still much needed. 3 minute read
