Guest Editorial Web-Based Intelligent Support Systems—Preface to the Special Section

The six articles in this special section aim at presenting the recent theoretical achievements and real-world applications in the developments of fuzzy set techniques in web-based support systems. It brings well-focused, high-quality publications in this area with the intent to report on significant results and promote the visibility of fuzzy sets. It raises awareness about the domain of web-based technologies as a high-potential subject area to be pursued by the fuzzy set research community. Moreover, we anticipate that some results presented in this special issue can be directly used by e-service researchers and developers to assist their provision of higher quality information and recommendations.
