信息构建视角下政府间国际组织门户网站主题导航方案研究　———以WHO/Europe门户网站为例

[ Purpose/Significance ] This paper analyzes the rationality of theme navigation of portal sites of intergovernmental international organizations and puts forward optimization strategies, which can improve the efficiency of portal sites to convey information to users. [Method/Process] From the perspective of information construction, starting from the association mechanism between the two pages of content relationships and link relationships, this paper constructed the association networks based on two different association mechanisms, compared and analyzed the K-means clustering and the original classification of topic navigation, measured the rationality of the existing topic navigation settings, and selected the theme portal WHO/Europe established in the European region under the World Health Organization as an example for empirical analysis. [ Result/Conclusion] Through the analysis and discussion of the rationality of the theme navigation setting of the empirical objects, this paper finds that the existing theme navigation methods of the website are unreasonable, including the inability to fully reflect the content relevance. Based on this, this paper puts forward systematic optimization suggestions on optimizing global navigation, adding links and enriching information contents from the macro, meso and micro levels, in order to give full play to the social benefits of information resources.
