pipe(note, nlp, n_jobs=-2, context=[], additional_spans='discarded', extensions=[], **kwargs)

Function to apply a spaCy pipe to a pandas or pyspark DataFrame

PARAMETER	DESCRIPTION
note	A pandas/pyspark/koalas DataFrame with a note_id and note_text column TYPE: DataFrame
nlp	A spaCy pipe TYPE: Language
context	A list of column to add to the generated SpaCy document as an extension. For instance, if context=["note_datetime"], the corresponding value found in thenote_datetimecolumn will be stored indoc._.note_datetime, which can be useful e.g. for thedates` pipeline. TYPE: List[str] DEFAULT: []
n_jobs	Only used when providing a Pandas DataFrame n_jobs=1 corresponds to simple_pipe n_jobs>1 corresponds to parallel_pipe with n_jobs parallel workers n_jobs=-1 corresponds to parallel_pipe with maximun number of workers n_jobs=-2 corresponds to parallel_pipe with maximun number of workers -1 TYPE: int, by default -2 DEFAULT: -2
additional_spans	A name (or list of names) of SpanGroup on which to apply the pipe too: SpanGroup are available as doc.spans[spangroup_name] and can be generated by some pipes. For instance, the date pipe populates doc.spans['dates'] TYPE: Union[List[str], str], by default "discarded" DEFAULT: 'discarded'
extensions	Spans extensions to add to the extracted results: For instance, if extensions=["score_name"], the extracted result will include, for each entity, ent._.score_name. TYPE: List[Tuple[str, T.DataType]], by default [] DEFAULT: []
kwargs	Additional parameters depending on the how argument. TYPE: Dict[str, Any]

RETURNS	DESCRIPTION
DataFrame	A DataFrame with one line per extraction

    Function to apply a spaCy pipe to a pandas or pyspark DataFrame


    Parameters
    ----------
    note : DataFrame
        A pandas/pyspark/koalas DataFrame with a `note_id` and `note_text` column
    nlp : Language
        A spaCy pipe
    context : List[str]
        A list of column to add to the generated SpaCy document as an extension.
        For instance, if `context=["note_datetime"], the corresponding value found
        in the `note_datetime` column will be stored in `doc._.note_datetime`,
        which can be useful e.g. for the `dates` pipeline.
    n_jobs : int, by default -2
        Only used when providing a Pandas DataFrame

        - `n_jobs=1` corresponds to `simple_pipe`
        - `n_jobs>1` corresponds to `parallel_pipe` with `n_jobs` parallel workers
        - `n_jobs=-1` corresponds to `parallel_pipe` with maximun number of workers
        - `n_jobs=-2` corresponds to `parallel_pipe` with maximun number of workers -1
    additional_spans : Union[List[str], str], by default "discarded"
        A name (or list of names) of SpanGroup on which to apply the pipe too:
        SpanGroup are available as `doc.spans[spangroup_name]` and can be generated
        by some pipes. For instance, the `date` pipe populates doc.spans['dates']
    extensions : List[Tuple[str, T.DataType]], by default []
        Spans extensions to add to the extracted results:
        For instance, if `extensions=["score_name"]`, the extracted result
        will include, for each entity, `ent._.score_name`.
    kwargs : Dict[str, Any]
        Additional parameters depending on the `how` argument.

    Returns

    DataFrame
        A DataFrame with one line per extraction
