Stop Words Cleaner for Greek


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_el", "el") \
        .setInputCols(["token"]) \
nlp_pipeline = Pipeline(stages=[document_assembler, tokenizer, stop_words])
light_pipeline = LightPipeline([['']]).toDF("text")))
results = light_pipeline.fullAnnotate("Εκτός από το ότι είναι ο βασιλιάς του Βορρά, ο John Snow είναι Άγγλος γιατρός και ηγέτης στην ανάπτυξη της αναισθησίας και της ιατρικής υγιεινής.")

val stopWords = StopWordsCleaner.pretrained("stopwords_el", "el")
