Evaluation System Based on Dynamic Weighted Averaging Algorithm and Its Application in WebGIS

摘要：

Evaluation systems based on Web is a convenient way for tourists to Understanding the attractions. However, many common Web-based evaluation systems have a shortcoming that there is no logical correlation between the total score and evaluation indicators or correlation is too simple. Obviously, only use the arithmetic mean value of evaluation indicators as the total score/star rating is difficult to meet the requirements of tourists who have special attention to service, price or traffic. Moreover, a high-total-score attraction with a low score in security should be early warning to users by a special color. The system discussed in this article established a more reasonable relationship between the indicators and the overall score/star rating by dynamic weighted averaging algorithm to make assessment results more accurately. This system can generate and adjust weights of each indicators automatically according to the users preferences. Furthermore, the system makes the attractions whose security have abnormal evaluations appears as special color by programming design. The algorithm based on Java language and JSP, use struts2 and spring3.5 as its framework, so it has strong portability to be applied in various terminals in the scenic spots and can be easily embedded in WebGIS systems.
