Stop Words Cleaner for Slovak

Description

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_sk", "sk") \
        .setInputCols(["token"]) \
        .setOutputCol("cleanTokens")
nlp_pipeline = Pipeline(stages=[document_assembler, tokenizer, stop_words])
light_pipeline = LightPipeline(nlp_pipeline.fit(spark.createDataFrame([['']]).toDF("text")))
results = light_pipeline.fullAnnotate("Okrem toho, že je kráľom severu, je John Snow anglickým lekárom a lídrom vo vývoji anestézie a lekárskej hygieny.")

val stopWords = StopWordsCleaner.pretrained("stopwords_sk", "sk")
        .setInputCols(Array("token"))
        .setOutputCol("cleanTokens")
