The features are present as LIST of LIST and I see the 1st and 3rd list are exactly the same. The contents of 1st list is present in the 2nd list as well. Then why don’t we just have features like below
Hi, according the documentation of LexicalSyntacticFeaturizer, the three lists in this case define the features that are extracted in a sliding window for the token before, the current token, and the following token. This allows following NLU components to take features from the surrounding tokens into account when looking at a particular token position.
So in this case the window is 1 on both sides of token. So if we can the info about 2 words on either side of the token then should we define it like below?
