Paperback. Na era digital, o rapido crescimento das plataformas online transformou significativamente o setor hoteleiro, onde as decisoes dos clientes sao cada vez mais influenciadas pelas avaliacoes geradas pelos utilizadores. Estas avaliacoes fornecem informacoes valiosas sobre as experiencias dos clientes; no entanto, o vasto volume de dados textuais nao estruturados torna a analise manual ineficiente e impraticavel. Para dar resposta a este desafio, este estudo propoe um sistema automatizado de analise de sentimentos que utiliza tecnicas de aprendizagem profunda para classificar as avaliacoes de hoteis em sentimentos positivos e negativos. A investigacao utiliza um conjunto de dados em grande escala, composto por mais de 500 000 avaliacoes de hoteis, que e submetido a um pre-processamento exaustivo, incluindo limpeza de texto, tokenizacao, remocao de palavras irrelevantes e equilibrio de dados, para garantir a fiabilidade do modelo. E realizada uma Analise Exploratoria de Dados (EDA) para compreender a distribuicao dos dados e extrair padroes significativos. Os dados textuais processados sao entao transformados em representacoes numericas utilizando tecnicas de tokenizacao e preenchimento de sequencias. Sao implementados dois modelos de aprendizagem profunda, a Memoria de Curto e Longo Prazo (LSTM) e a Memoria de Curto e Longo Prazo Bidirecional (BiLSTM), para captar dependencias sequenciais e relacoes contextuais. This item is printed on demand. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…
