Hi there,

is there a possibility to filter tokens by startwords (imported from a csv), so that only  the tokens matching one startword are passed through?

Kind of an inversion of the "Filter Stopwords (Dictionary)" operator.

Thx in advance

    Hi,

    I think this is not possible unfortunately. This should be no real problem to implement though. If we face that problem we will surely add such an operator somewhen. Until then, the only solution for you is to extend RapidMiner by writing your own operator or by writing a script.

    Kind regards,
    Tobias
