What are the Basic Steps in Portuguese Sentiment Analysis?
Repustate has a massive corpus of Portuguese text that has been tagged
as the first step towards Portuguese sentiment analysis. This corpus is then
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 Portuguese text.
Feed this text into an ML-based algorithm to create an Portuguese
Granulate the algorithm for deeper accuracy using NER.
Extract the sentiment score for each aspect, theme, and topic.
Repustate uses Portuguese Named Entity Recognition
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.

Nem todas as línguas são iguais
As regras de gramática variam de uma língua para a outra. As regras da conjugação verbal, concordância entre o nome e o verbo e as negações variam de uma língua para a outra.
O português é uma língua única e difere do inglês em vários aspetos. Usar as mesmas técnicas e modelos de linguagem que funcionam para análise de sentimentos em inglês ao conduzir análise de sentimentos em português produziria resultados extremamente imprecisos.
Foi por isso que o Repustate desenvolveu ferramentas específicas para o português para ajudar na análise de sentimentos em português, incluindo uma marcação de uma parte do texto, um "lemmatizer" de português, e claro, modelos de sentimentos específicos para o português.
Marcação de uma parte do texto do português
A marcação de uma parte do texto do português permite que o Repustate limite onde possa estar um sentimento numa caixa de texto. Verbos, nomes e adjetivos, fornecem as sugestões necessárias para determinar o sentimento.
Para criar uma marcação de uma parte do texto em português que seja precisa e rápida, precisa de ter grandes corpos de texto em português marcados manualmente. Este texto em português pode depois ser introduzido numa máquina de aprendizagem de algoritmos para criar uma marcação de uma parte de texto em português.
Quanto maior o corpo, e mais importante, quanto mais variado o corpo, melhores os resultados ao criar a marcação da parte do texto em português. O Repustate criou um corpo massivo de texto em português arrastando dados de uma variedade de fontes para garantir uma boa cobertura.
Modelos de sentimentos da língua portuguesa
O Repustate desenvolveu modelos de sentimentos de línguas específicos para o português para capturar as várias frases, idiomas e expressões que ajudam a definir o sentimento ao escrever em português. Compreender os vários aspetos gramaticais do português que o tornam único e bastante diferente do inglês é o que permite que a análise de sentimentos do Repustate em português seja tão rápida e tão precisa quanto é.
