Unlike other service evaluation model, this study suggests a 4 dimensional approach in evaluating web services. It uses reciprocal evaluation\u0000 methods on a web service by both services providers and service users. It identifies the cognitive differences on web services between these two groups. The study also uses text mining technologies such as social mining and topic analysis to find images of the web services. The results from\u0000 the study show that there are significant differences between the evaluations on web services by service providers and service users. There are also differences between images of a service provider from news data and social media data. These differences are represented with keywords related\u0000 to the service providers. Texts from news are collected and analyzed to have more object images of a web service providers. Texts from social media are collected and analyzed to have more personal images of a web service providers. A decision tree analysis, as a data mining tool, is used to\u0000 induce and to produce a strategy to understand the cognitive differences and to improve the quality of services. A decision tree analysis is used to find the pattern and to explain the difference between service providers and service users. It can be used to better understand the quality of\u0000 their services and to improve the quality of service from service provider’s point of view. The approach this study suggests can be used to other evaluation areas such as customer satisfaction on new products or services.","PeriodicalId":15416,"journal":{"name":"Journal of Computational and Theoretical Nanoscience","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46705295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
