    I am not totally clear about what you mean by "removing negation" from tweets.  Do you simply want to eliminate negative words like (no, not, never, etc.) from your analysis?

    If so, one way would be to process your tweets as text, tokenizing by non-letters (to get individual words), and then create a custom stopword dictionary for negative words and use the Stopword (Dictionary) operator to remove them.  You can also use Replace Tokens for any abbreviations that you want to expand to the full word.

    @gham @khazan If you want to alert someone to your post, I suggest using the '@' symbol and their name, like @Telcontar120. Threads get buried after a while.

     

    With respect to remicing negative words, how is this good if you're trying to understand emotion/sentiment? To turn words into abbreviations or something else, you can use the Replace Token operator or Replace operator.

     

    Also, it' always best to post your XML process, community members have a hard time guessing what some posters are thinking.

    hello @gham I am sorry to say this but I am starting to issue temporary bans to users who cannot understand the protocol on how to ask questions on the community. In order to ask a question like this, you MUST post your process XML at the least. There are instructions on how to do this in many, many places including here: https://youtu.be/KkgB5QXWXJ8, and the enormous "Read Before Posting" banner on right when you post/reply to any message.

     

    Please post your XML so we can help you better.

     

    Respectfully,
