DESCRIPTION

This component filters the tokens of the input based on the list of tokens provided. The component has 3 inputs for the type of data to be filtered (tokens, token counts or tokenized sentencesand one input for the list of tokens to filter. It will output the same data type it received. If new tokens to filter are provide they either replace the current ones or add them to the black list. The component waits for a black list and then begins processing the data it receives. The component outputs the filtered tokens, token counts or tokenized sentences. The comparison of blacklisted tokens to the data will ignore case by default. Set ignore_case=false to work in case sensitive mode.
