Given requirements are met, this applies ML transformation within a Pipeline or stand-alone Output annotation will be generated as a new column, previous annotations are still available separately metadata is built at schema level to record annotations structural information outside its content

True if all the required types are present, else false
Required input and expected output annotator types
Annotator that cleans out tokens. Requires stems, hence tokens.
Removes all dirty characters from text following a regex pattern and transforms words based on a provided dictionary
