    IAnnotation trait is used to abstract the annotator's output for each NLP tasks available in Spark NLP.

    Currently Spark NLP supports three types of outputs:

    LightPipeline models in Java/Scala returns an IAnnotation collection. All of these outputs are structs with the required data types to represent Text, Image and Audio.

    If one wants to access the data as Annotation, AnnotationImage or AnnotationAudio, one just needs casting to the desired output.

    This transformer parses text into tabular representation.

    This transformer parses text into tabular representation. The input consists of DOCUMENT annotations and the output are TABLE annotations. The source format can be either JSON or CSV. The format of the JSON files should be:

    {
  "header": [col1, col2, ..., colN],
  "rows": [
    [val11, val12, ..., val1N],
    [val22, va22, ..., val2N],
    ...
   ]
}

    The CSV format support alternative delimiters (e.g. tab), as well as escaping delimiters by surrounding cell values with double quotes. For example:

    column1, column2, "column with, comma"
value1, value2, value3
"escaped value", "value with, comma", "value with double ("") quote"

    The transformer stores tabular data internally as JSON. The default input format is also JSON.
