Text classification with multiple topics
I´m quite new here in RapidMiner and I´ve seen many text classificators to set each text in one topic or another. My aproach is a little different: I want to classify also text but the point is that my text may have multiple topics. For example:
I have as topics science, biology, informatics ... and texts belong to this topics, but one can belong to more than one at the same time, for example a text can be about science and informatics. Can i set any kind of array to do this or how could i do this job?
