Re: text visualizer

Which extension did you install to get the TextVisualizer?

Re: text visualizer

Sorry for replying to such an old post, but I have the exact same problem.

The TextVisualizer from the IE plugin gives me this error when I try to run the first sample (1_Read-Tokenize-Visualize).

Is the plugin broken/no longer supported? There seem to have been no updates over the last two years.

Re: text visualizer

OK, solved the issue myself: The plugin on the marketplace is NOT up-to-date (if any RapidMiner folks are on this forum, pay attention... Smiley Happy).

So to get the IE plugin to work correctly, you need to download the latest jar here:


Uninstall the Marketplace version, if you have it installed.
Then, place the jar (rapidminer-Information-Extraction-1.0.2.jar) in your $RAPIDMINER_HOMER/lib/plugins directory.

To get the examples I mentioned above, do:

svn checkout https://svn.code.sf.net/p/ieplugin4rm/code/informationextractionplugin_Vega/trunk/informationExtract...
mv samples ~/.RapidMiner/repositories/MyRepo/

Finally, the IE plugin works! (Well, the examples, at least - still have to see if this is generally true...)

Restart RapidMiner.

Re: text visualizer


this is not an extension developed by us so we can't do much about the marketplace version.
Thanks for sharing how to get it to work though!
