This paper aims to conduct a comparative analysis of two of the most popular cloud computing platforms, namely Amazon Web Services (AWS) and Microsoft Azure, in terms of their sentiment detection services through the complex analysis of multiple texts. The comparative analysis was carried out by implementing an application that integrates both the sentiment analysis (SA) solutions provided by Amazon Web Services and those offered by Microsoft Azure. To evaluate the services offered by the two platforms, different evaluation metrics were analyzed and compared, such as accuracy, precision, recall, and other relevant characteristics. Also, the paper examines the costs and limitations of the two platforms, Amazon Comprehend and Azure AI Language Text, when they are used to implement solutions for analyzing the sentiments of product reviews. The results obtained highlighted the advantages and disadvantages between the two platforms from several perspectives, such as performance, the quality of the answers provided, or their accuracy. All these aspects help to obtain a clear picture of the advantages and limitations of each service offered by the two cloud platforms.<\/jats:p>","DOI":"10.3390\/bdcc8120166","type":"journal-article","created":{"date-parts":[[2024,11,21]],"date-time":"2024-11-21T04:46:11Z","timestamp":1732164371000},"page":"166","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Sentiment Analysis Using Amazon Web Services and Microsoft Azure"],"prefix":"10.3390","volume":"8","author":[{"given":"Sergiu C.","family":"Ivan","sequence":"first","affiliation":[{"name":"Department of Computers and Information Technology, University of Oradea, 410087 Oradea, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7027-5750","authenticated-orcid":false,"given":"Robert \u015e.","family":"Gy\u0151r\u00f6di","sequence":"additional","affiliation":[{"name":"Department of Computers and Information Technology, University of Oradea, 410087 Oradea, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7815-4355","authenticated-orcid":false,"given":"Cornelia A.","family":"Gy\u0151r\u00f6di","sequence":"additional","affiliation":[{"name":"Department of Computers and Information Technology, University of Oradea, 410087 Oradea, Romania"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"131","DOI":"10.14257\/ijast.2018.118.12","article-title":"Amazon Machine Learning vs. Microsoft Azure Machine Learning as Platforms for Sentiment Analysis","volume":"118","author":"Harfoushi","year":"2018","journal-title":"Int.
