Sweet Tools Listing

Version 11 Shows Semantic Web Tools Announcements to be on a Furious Pace

This AI3 blog maintains Sweet Tools, the largest listing of about 800 semantic Web and -related tools available. Most are open source. Click here to see the current listing!

After a two months hiatus, I have just updated AI3's listing of semantic Web and -related tools to version 11; follow the links below.

This version adds 72 new tools — one of the largest additions ever — since the last update on September 16, bringing the new total to 650 tools.

Like prior versions, this new Sweet Tools listing is provided either as:

Background on prior listings and earlier statistics may be found on these previous posts:

With interim updates periodically over that period.

In thanks to Henry Story, whose chat note prompted me to post this long overdue update, I have also included some of the tools breakdowns he enjoys.

Here is a table of tools categories, showing both the last breakdown from about 9 months ago when there were 500 tools in the listing, and today with 650 tools:

The fastest growing categories are listed first, with RDF, ontologies, and search growing the most. Note some categories have been added and others are being re-classified or delisted as time and familiarity with the listing grows. Certain areas of current interest, such as NLP, also see increased listings as a result. Of course, all such categorizations have a degree of arbitrariness.

As with the last survey, Java and JavaScript are dominant languages, with considerable growth. Python and PHP have also shown higher than average growth. Ruby appears to have stagnated, and many other languages are in second-tier positions:

You’ll be pleased to see, Henry, that Java is still holding serve on market share!

Note: Because of comments expirations on prior posts, this entry is now the new location for adding a suggested new tool. Simply provide your information in the comments section, and your tool will be included in the next update. (Hopefully, that will not take another two months!) :)
