Stop Words Cleaner for German


This model removes ‘stop words’ from text. Stop words are words so common that they can removed without significantly altering the meaning of a text. Removing stop words is useful when one wants to deal with only the most semantically important words in a text, and ignore words that are rarely semantically relevant, such as articles and prepositions.

How to use

stop_words = StopWordsCleaner.pretrained("stopwords_de", "de") \
        .setInputCols(["token"]) \
nlp_pipeline = Pipeline(stages=[document_assembler, tokenizer, stop_words])
light_pipeline = LightPipeline([['']]).toDF("text")))
results = light_pipeline.fullAnnotate("John Snow ist nicht nur der König des Nordens, sondern auch ein englischer Arzt und führend in der Entwicklung von Anästhesie und medizinischer Hygiene.")

val stopWords = StopWordsCleaner.pretrained("stopwords_de", "de")
