Balance is very important in all areas from art down to the details of our daily life. There is no exception in research work especially when we want to develop an application which will be used in the real world. Currently more and more semantic Web applications are emerging. Although there are some researches on the evaluation and benchmarking of semantic Web applications, they mainly focused on the semantic Web technology itself or specific types of applications. The evaluation of general features of Semantic Web applications is not sufficient. In this paper, we will focus on the evaluation of one of the general characteristics - balance of semantic Web applications. An analysis of current semantic Web applications will be given first in order to summarize their statistical features and get some hints for identifying the aspects that are critical for balance evaluation. Then we summarize the main aspects of balance evaluation, and present the key factors for each balance evaluation aspect. Finally, suggestions for future semantic Web application development and evaluation will be made based on the analysis of semantic Web applications and the summarizing of balance evaluation aspects.
