  ]
}

실제 사용 방법은 Elasicsearch analysis를 참고하세요.

User Dictionary

기본사전 이외에 사용자가 원하는 단어를 추가하여 사용할 수 있습니다. 예를들어 말썽쟁이를 분석하면 말썽(Noun)쟁이(suffix)로 추출되지만, 사전에 말썽쟁이를 추가하면 말썽쟁이(Noun)로 추출할 수 있습니다.

Analyzer Plugin을 설치하면 {ES_HOME}/plugins/elasticserach-analysis-openkoreantext 위치에 dic/ 디렉토리를 찾을 수 있습니다. 해당 디렉토리 안에 사전 텍스트 파일을 추가하면 됩니다.

사전 텍스트 파일은 각 단어들을 줄바꿈하여 넣으면 됩니다. (단, 띄워쓰기는 단어로 인식하지 않습니다.)

# {ES_HOME}/plugins/elasticserach-analysis-openkoreantext/dic/sampledictionary
말썽쟁이
뚜쟁이
욕쟁이할머니
...

Components

이 Analyzer는 몇 가지 components로 구성되어 있습니다.

Charater Filter

  • openkoreantext-normalizer
    • 구어체를 표준화 합니다.

    훌쩍훌쩍훌쩍훌쩍 -> 훌쩍훌쩍, 하겟다 -> 하겠다, 안됔ㅋㅋㅋ -> 안돼ㅋㅋ

Tokenizer

  • openkoreantext-tokenizer
    • 문장을 토큰화 합니다.

    한국어를 처리하는 예시입니다 ㅋㅋ -> [한국어, 를, 처리, 하는, 예시, 입니다, ㅋㅋ]

Token Filter

  • openkoreantext-stemmer  * 형용사와 동사를 스테밍합니다.

    새로운 스테밍을 추가했었다. -> [새롭다, 스테밍, 을, 추가하다, .]

  • openkoreantext-redundant-filter

    • 접속사, 공백(띄워쓰기), 조사, 마침표 등을 제거합니다.

    그리고 이것은 예시, 또는 예로써, 한국어를 처리하기 -> [예시, 예, 한국어, 처리, 하다]

  • openkoreantext-phrase-extractor

    • 어구를 추출합니다.

    한국어를 처리하는 예시입니다 ㅋㅋ -> [한국어, 처리, 예시, 처리하는 예시]

Analyzer

[openkoreantext-normalizer] -> [openkoreantext-tokenizer] -> [openkoreantext-stemmer, openkoreantext-redundant-filter, classic, length, lowercase]

  • 이 analyzer에는 openkoreantext-phrase-extractor가 기본 token filter로 적용되어있지 않습니다.
  • custom analyzer 구성을 원하시면 custom analyzer를 참고하세요.
