ISWC 2010 Attendees by Country
This is a preliminary stat of ISWC attendees by country. Data is from registration list as of Oct 28, 2010, and the final data may be a little different. Also note that it’s different from the author/organizer data.
By no surprise, the host country China has the most attendees (15.4%). US, UK and Germany follow as the next biggest players (14.9%, 14.4%, 12.6%), respectively. By continents, we have
Antarctica: 0% – not surprising, isn’t it ?
Clearly, Europe is still the most active in Semantic Web research. We also see this fact by various other statistics, e.g., orgnaizations involved in recent semantic web events.

The following tools are used:
- The original data is in spreadsheet. Countries are given in ISO 3166-1 alpha-2 code, e.g., Netherlands is NL, which many people are not familiar with. I found the code-to-name mapping from another source. However, as Excel can’t do join, I imported the two csvs into one RDF file using TopBraid Composer (here is how).
- A SPARQL query is used to do the join, the result is saved as a Google Docs spreadsheet.
- The spreadsheet is visualized by Datapress.
The SPARQL query I used
SELECT count(?subject) ?n
?subject a :Person ;
:country [:name ?n] .
GROUP BY ?n
It’s really likely that I missed some tools that can do the job easier, as semantic tools have been mushroomed in the recent years. I will keep looking for better ways to visualize ISWC data – in the end, I wish everyone, especially non-prorammers, can do it. That will show the most of the beauty of semantics. I believe we are very close to that.
