Comparação de ferramentas de processamento de linguagem natural para análise de sentimento em português: um estudo de caso em avaliações online de hotéis

Abstract

Apply natural language processing tools and Machine Learning tools to conduct a sentiment analysis in online hotel reviews. The score of a review does not convey all the expressiveness of the user's review, so there is a need to apply an analysis in the texts of the online reviews to obtain better parameters for the hotel's online reputation statistics. Search for natural language processing tools and Machine Learning tools to extract the parameters from a sentiment analysis in the reviews. It is expected with the application of these tools it will be possible to obtain a sentiment analysis in hotels reviews, thus making it possible to have a more concise analysis of the company's online reputation.
