Filter terms that were tagged by two taggers

Hi,

how is it possible to filter the terms that were tagged by two taggers? 

I know that, "If two named entity recognizers are applied one after the other, the latter will overwrite the tagging of the former in case of conflicts" (source: https://www.knime.org/files/knime_text_processing_introduction_technical_report_120515.pdf). 

To understand my case: I did a Sentiment Analysis and used one dictionary tagger for positive and one for negative words (in this order). Now, some words get this result in the term column: 

[POSITIVE(SENTIMENT) NEGATIVE(SENTIMENT)]

Becaus I uses the dictionary tagger with the negative dictionary last, this term is tagged as negative. Now I want to take an extra look at terms that were tagged twice.

Does somebody has a clue?

Thanks a lot 

Jasmin

You can use two General Tag Set Filter nodes in a row for this. First filter all positive words and then all negative words. Don't forget to check the "ignore unmodifiability" box to filter also tagged and thus unmodifiable words.
