Such evaluation and computation processes are closely related to sentiment analysis and opinion mining. These techniques incorporate new features into traditional tasks, like polarity detection for positive or negative reviews. The \u201call excellent reputation\u201d problem is common in the e-commerce domain. Another problem is that sellers can write unfair reviews to endorse or reject any targeted product since a higher reputation leads to higher profits. Therefore, the purpose of the present work is to use a statistical technique for excluding unfair ratings and to illustrate its effectiveness through simulations. Also, the authors have calculated reputation scores from users' feedback based on a sentiment analysis model (SAM). Experimental results demonstrate the effectiveness of the approach.<\/p>","DOI":"10.4018\/ijoci.2020010103","type":"journal-article","created":{"date-parts":[[2019,11,29]],"date-time":"2019-11-29T04:45:11Z","timestamp":1575002711000},"page":"32-62","source":"Crossref","is-referenced-by-count":11,"title":["Building Sentiment Analysis Model and Compute Reputation Scores in E-Commerce Environment Using Machine Learning Techniques"],"prefix":"10.4018","volume":"10","author":[{"given":"Elshrif Ibrahim","family":"Elmurngi","sequence":"first","affiliation":[{"name":"\u00c9cole de Technologie Sup\u00e9rieure, Montreal, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9117-5743","authenticated-orcid":true,"given":"Abdelouahed","family":"Gherbi","sequence":"additional","affiliation":[{"name":"\u00c9cole de Technologie Sup\u00e9rieure, Montreal, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"IJOCI.2020010103-0","doi-asserted-by":"publisher","DOI":"10.5539\/cis.v6n4p59"},{"key":"IJOCI.2020010103-1","unstructured":"Abdel-Hafez, A., Xu, Y., & Tjondronegoro, D.
