Create the Classifier Mapping

Create the Classifier Mapping

You create a mapping that reads a data source, classifies the languages in the data, and writes the data to targets based on the languages they contain.
The following image shows the mapping in the Developer tool:
The mapping contains a data source object, a Classifier transformation, a Router transformation, and two data target objects. The mapping writes data to either target object based on the language used in the data.
The mapping you create contains the following objects:
Object Name
Description
Read_tweet_user_lang
Data source.
Contains the twitter messages
Classifier
Classifier transformation.
Identifies the languages used in the twitter messages.
Router
Router transformation.
Routes the twitter messages to data target objects according to the languages they contain.
Write_en_tweets_out
Data target.
Contains twitter messages in English.
Write_other_tweets_out
Data target.
Contains non-English-language twitter messages.
