摘要

Development of information technology makes the production of data increase dramatically. We can get lots of data from the internet, including data reviews about a product or service. The more data obtained, the system is needed to process it. Sentiment analysis is a text processing of Natural Language Processing (NLP) that can help someone to see the quality of service offered, including hotel services. This paper uses hotel review data to carry out sentiment analysis obtained from the Traveloka website. The data classified using the Long Short-Term Memory (LSTM) algorithm. To get better results, the authors use word embedding to convert words into vectors. This study aims to compare the performance of several word embedding, while word embedding compared is word2vec Continuous Bag of Words CBOW, word2vec skip-gram, doc2vec, and glove. From the experiment conducted, the results show that the glove method has the highest accuracy of 95.52% while the word2vec skip-gram model has the lowest accuracy of 91.81%, so it concluded that the glove method is the best word embedding method for hotel review data.
