Elastic Personalized Nonfunctional Attribute Preference and Trade-off Based Service Selection

Kenneth K. Fletcher, Xiaoqing F. Liu, Mingdong Tang
2015 ACM Transactions on the Web  
For service users to get the best service that meet their requirements, they prefer to personalize their nonfunctional attributes, such as reliability and price.  ...  The method allows users to represent their elastic nonfunctional requirements and associated importance using linguistic terms to specify their personalized trade-off strategies.  ...  A service user may specify his or her nonfunctional requirements on, for instance, service response time (the lower the value, the better the nonfunctional attribute) as follows: the response time for  ...
