"Unknown operator class GSP in text plugin samples"

Hello all,
I am looking at the samples provided with the text plugin and I cannot get one of the samples to load because RM cannot find an operator called GSP. This is contained in the sample "06_GSP". Here's a fragment referring to it.
It would be great if this GSP class really existed somewhere. Can anyone offer any assistance?
hopefully,
Andrew

It looks similar to Weka W-GeneralizedSequentialPatterns but try as I might, I cannot get this to work in RM (it works in Weka itself though :-\).
<operator name="GSP" class="GSP">
<parameter key="dateAttribute" value="time"/>
<parameter key="maxGap" value="0.0"/>
<parameter key="maxPass" value="6"/>
<parameter key="maxTxItems" value="6"/>
<parameter key="minSup" value="0.3"/>
<parameter key="seqenceIdAttribute" value="session"/>
It would be great if this GSP class really existed somewhere. Can anyone offer any assistance?
hopefully,
Andrew

this seems to be a rather old sample process. The former GSP operator has long been removed as far as I know. I think the main reason was its incompatible license and it never worked reliable.
We have currently an own implementation of GSP which is working quite well with RapidMiner 4.6, but it is sold separately as extension for RapidMiner. If you are interested, please write an email to contact@rapid-i.com.
