"installing text extension with WordNet ( JWNL)"

Question

Hello.  I have the text extension up and running with version 4.2.  I also have WordNet 2.1 installed on my XP box.  The docs mention a JWNL sample configuration file in the "samples" directory, but I cannot for the life of me find it.  I would appreciate any suggestions on taking this last step to link word net with RM.  Cheers,  --chris

Hi,

actually no, wordnet is not supported by the current version (4.6 as well as 5.0) of the text processing extension. Maybe we will re-add this feature somewhen in the future although this is not planned for the short-term.

Best regards,
Tobias

Doesn`t exist any solution to make the wordnet support work for the synonym stemmer step? Or isn`t wordnet supported at all in rapid miner 4.6 text plugin?

Hi,

the WordNet bridge is no longer supported by the TextInput plugin. Sorry for the outdated documentation...

The main reason are the poor results it produced as JWNL did not support any part-of-speech or frequency information. So often ambigious words were not resolved correctly adding a lot of noise.

However, there is an upcoming 2.0 release of JWNL with an extended API that looks very promising. So maybe it would be a good idea to use this new version to write WordNet operators for the current version of the TextInput plugin.

As a point of departure, the code in the WVTool project could be used.

Best regards,
Michael
