Spark NLP MultiDateMatcher

Description

Spark ML transformer that reads from different forms of date and time expressions and converts them to a provided date format. E See https://nlp.johnsnowlabs.com/docs/en/annotators#multidatematcher

Usage

nlp_multi_date_matcher(
  x,
  input_cols,
  output_col,
  anchor_date_day = NULL,
  anchor_date_month = NULL,
  anchor_date_year = NULL,
  default_day_when_missing = NULL,
  read_month_first = NULL,
  format = NULL,
  source_language = NULL,
  uid = random_string("multi_date_matcher_")
)

Arguments

x	A spark_connection, ml_pipeline, or a tbl_spark.
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
default_day_when_missing	Which day to set when it is missing from parsed input (Default: 1)
read_month_first	Whether to interpret dates as MM/DD/YYYY instead of DD/MM/YYYY (Default: true)
format	Output format of parsed date. Defaults to yyyy/MM/dd
source_language	Source language for explicit translation
uid	A character string used to uniquely identify the ML estimator.

Value

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.
