What are the Basic Steps in Korean Sentiment Analysis?

Repustate has a massive corpus of Korean text that has been tagged manually, as the first step towards Korean sentiment analysis. This corpus is then processed by an ML model for high precision in aggregate sentiment scoring. The steps can be laid out as:

  1. Collect a massive, highly varied corpus (collection of texts) of the manually tagged Korean text.
  2. Feed this text into an ML-based algorithm to create an Korean part-of-speech tagger.
  3. Granulate the algorithm for deeper accuracy using NER.
  4. Extract the sentiment score for each aspect, theme, and topic.

Repustate uses Korean Named Entity Recognition (NER) with advanced semantic search to identify brand and business entities in data. No matter how misspelled a word is, the Korean NLP model will reproduce the name in the native script and give accurate name search, transliteration, and identity verification measures. This gives high-accuracy ranked results, based on the linguistic, phonetic, and specific cultural variation patterns of the names.

Should translations be used for Korean sentiment analysis?

Trying to achieve Korean sentiment analysis by using an API that uses translations can yield incorrect results. So, the answer is, no. As your Korean sentiment analysis company, Repustate, uses intricate Korean NLP for higher accuracy in sentiment scoring of your data. This is because translations dilute the nuance of a statement. If a text has multiple topics, sentiments, and themes, as reviews and comments usually do, the aggregate semantic score of the data (+1 for positive, and -1 for negative) will be inaccurate with translations.

언어라고 다 같은 게 아니다

문법 규칙은 언어마다 다 다릅니다. 동사 활용, 명사와 동사의 일치, 부정 표현에 관한 규칙이 언어마다 다 다르다는 이야기입니다.

한국어는 하나의 고유한 언어로, 영어와 여러 모로 다릅니다. 한국어 정서를 분석하면서 영어 정서를 분석할 때 쓰는 기술과 언어 모델을 똑같이 사용해 버리면 아주 부정확한 결과가 나오고 맙니다.

그래서 Repustate는 한국어 특화 정서 모델은 물론, 한국어 품사 식별기(tagger), 한국어 어휘 정리기(lemmatizer) 등 한국어 정서 분석에 일조하기 위한 한국어 특화 도구를 개발했습니다.

한국어 품사 식별

Repustate는 한국어 품사 식별을 이용해 문서의 한 단락 속에서 정서가 드러난 부분을 추립니다. 동사, 명사, 형용사는 정서를 알아내는 데 필요한 단서가 되기 때문입니다.

신속하고 정확한 한국어 품사 식별기를 만들기 위해서는 막대한 말뭉치가 필수인데, 이 말뭉치란 손수 품사를 식별해 놓은 한국어 문서를 가리킵니다. 이 한국어 문서는 기계 학습 알고리즘에 넣어 한국어 품사 식별기를 만드는 데 쓰입니다.

말뭉치가 클수록 좋은 것은 맞지만, 그보다 더 중요한 것은 다양해야 한다는 것입니다. 다양할수록 더 나은 한국어 품사 식별기를 만들 수 있습니다. Repustate는 넓은 범위를 보장하기 위해 다양한 출처에서 자료를 구해 막대한 양의 한국어 말뭉치를 만들어 냈습니다.

한국어 정서 모델

Repustate는 한국어를 글로 적을 때 정서가 드러나는 표현, 숙어, 구문을 다양하게 포착하고자 한국어에 특화된 정서 언어 모델을 개발했습니다. 또, 영어와 확연하게 구분되는 한국어의 고유하고 다양한 문법 특성을 이해한 덕에 한국어 정서를 매우 신속하고 정확하게 분석할 수 있습니다.
