A Fuzzy TOPSIS Approach for Evaluating the Quality of Breast Cancer Information on the Internet

摘要

Breast cancer, a worldwide disease that typically affects women, is among the most ubiquitous types of malignant tumors and is the result of abnormal growth of breast cells. Despite heavy reliance on the internet to obtain breast cancer information, the credibility of provided information remains unclear. Inaccurate information causes detrimental consequences to the public. Evaluating the quality of online information on breast cancer is a challenge and therefore requires a rational and systematic evaluation method. This study aimed to evaluate the quality of online information on breast cancer based on fuzzy TOPSIS with the application of linguistic variables, which assists expert decision making in terms of uncertainty and subjectivity. The results can then be used to identify credible websites that can educate the public, including breast cancer patients, on breast cancer issues. Moreover, this study assists in validating the quality of online information on breast cancer. The results obtained from this study were compared to the results obtained using VIKOR, which is a beneficial tool for evaluating the quality of online information on other health issues as well.
