Hi Jose,

Are you asking if you can have terms of more than one word/token? If so, the answer is yes. After you tokenize, use the Generate n-Grams (Terms) operator. This will generate phrases of n sequential tokens. Note: you will still have the single terms in your term-by-document matrix too. For example, generating 2-grams you would have "heart", "attack", and "heart attack" in the matrix.

ok, perfect, thanks

How can I have only 2-grams and not 1-grams? e.g. "Heart Attack" and not "Heart" + "Attack" in the matrix?

Hi,

i think there is no way from preventing it to generate the table. There is the option however to use a clever Regex in Select Attributes and simply remove them.
