Sentiment Analysis

Hello, Why Sentiment value are not categorizing with postive and negative values ?
it shows null value or invalid value

hi @alizasnow

Have you seen this workflow on Sentiment Analysis from the KNIME Hub. It is a good starting point to do your sentiment analysis. To do a sentiment analysis you need a labeled dataset with POS/NEG sentiment (as in this example from the hub) as a starting point to score your “unseen” data. And yes that is a little bit of work… Another route may be to google for a Sentiment Analysis Wordlist and use this words to enrich your text/docuements.
