What are the Basic Steps in Vietnamese Sentiment Analysis?
Repustate has a massive corpus of Vietnamese text that has been tagged manually,
as the first step towards Vietnamese 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:
Collect a massive, highly varied corpus (collection of texts) of the manually tagged Vietnamese text.
Feed this text into an ML-based algorithm to create an Vietnamese part-of-speech tagger.
Granulate the algorithm for deeper accuracy using NER.
Extract the sentiment score for each aspect, theme, and topic.
Repustate uses Vietnamese Named Entity Recognition (NER) with
advanced semantic search to identify brand and business entities in data. No matter how misspelled a word is,
the Vietnamese 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 Vietnamese sentiment analysis?
Trying to achieve Vietnamese sentiment analysis by using an API that uses translations can
yield incorrect results. So, the answer is, no. As your Vietnamese sentiment analysis company,
Repustate, uses intricate Vietnamese 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.
