Portuguese Language Sentiment Models

Repustate has developed sentiment language models specific to Portuguese to capture the various phrases, idioms, and expressions that help define certain sentiments. It turns unstructured Portuguese data into business intelligence you can use to increase your value proposition, brand experience, and value delivery.

What are the Basic Steps in Portuguese Sentiment Analysis?

Repustate has a massive corpus of Portuguese text that has been tagged manually, as the first step towards Portuguese 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 Portuguese text.
2. Feed this text into an ML-based algorithm to create an Portuguese 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 Portuguese Named Entity Recognition (NER) with advanced semantic search to identify brand and business entities in data. No matter how misspelled a word is, the Portuguese 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 Portuguese sentiment analysis?

Trying to achieve Portuguese sentiment analysis by using an API that uses translations can yield incorrect results. So, the answer is, no. As your Portuguese sentiment analysis company, Repustate, uses intricate Portuguese 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.
