nlp_date_normalizer | R Documentation |
Spark ML transformer that tries to normalize dates in chunks annotations. The expected format for the date will be YYYY/MM/DD. If the date is normalized then field normalized in metadata will be true else will be false. See https://nlp.johnsnowlabs.com/licensed/api/com/johnsnowlabs/nlp/annotators/normalizer/DateNormalizer.html
nlp_date_normalizer( x, input_cols, output_col, anchor_date_day = NULL, anchor_date_month = NULL, anchor_date_year = NULL, uid = random_string("date_normalizer_") )
x |
A |
input_cols |
Input columns. String array. |
output_col |
Output column. String. |
anchor_date_day |
Add an anchor day for the relative dates such as a day after tomorrow (Default: -1). By default it will use the current day. The first day of the month has value 1 |
anchor_date_month |
Add an anchor month for the relative dates such as a day after tomorrow (Default: -1). By default it will use the current month. Month values start from 1, so 1 stands for January. |
anchor_date_year |
Add an anchor year for the relative dates such as a day after tomorrow (Default: -1). If it is not set, the by default it will use the current year. Example: 2021 |
uid |
A character string used to uniquely identify the ML estimator. |
The object returned depends on the class of x
.
spark_connection
: When x
is a spark_connection
, the function returns an instance of a ml_estimator
object. The object contains a pointer to
a Spark Estimator
object and can be used to compose
Pipeline
objects.
ml_pipeline
: When x
is a ml_pipeline
, the function returns a ml_pipeline
with
the NLP estimator appended to the pipeline.
tbl_spark
: When x
is a tbl_spark
, an estimator is constructed then
immediately fit with the input tbl_spark
, returning an NLP model.
