The paper selects &amp;ldquo;dirty porterhouse of one well-known catering enterprise&amp;rdquo; food safety public event in 2016, setting up comprehensive evaluation index system by AHP: the media, net citizen and government as the criterion level. Index weight can be calculated with improved entropy method. The state transition matrix will be constructed and food safety of public opinion's change interval will also be predicted by Markov. The results show that the comprehensive construction of the index system and the improved entropy weight method indeed improve the accuracy of the Markov model, and effectively realize the prediction of food safety public opinion finally.<\/jats:p>","DOI":"10.3233\/978-1-61499-927-0-30","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T05:26:53Z","timestamp":1740115613000},"source":"Crossref","is-referenced-by-count":0,"title":["Prediction of Food Safety Network of Public Opinion Hot-Degree Based on Improved Entropy Method and Markov"],"prefix":"10.3233","author":[{"family":"Hong Xiaojuan","sequence":"additional","affiliation":[]},{"family":"Zhang Cong","sequence":"additional","affiliation":[]},{"family":"Huang Weidong","sequence":"additional","affiliation":[]},{"family":"Hong Wei","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Fuzzy Systems and Data Mining IV"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T05:44:31Z","timestamp":1740116671000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-926-3&spage=30&doi=10.3233\/978-1-61499-927-0-30"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-927-0-30","relation":{"is-cited-by":[{"id-type":"doi","id":"10.1155\/2021\/9936965","asserted-by":"object"}]},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2018]]}}}
