兼顾用户因素的地理信息资源检索研究

Research on Geographic Information Resources Retrieval Considering User Factors

在地理信息资源检索应用中,用户因素会对检索结果产生很大影响。但现有地理信息资源检索应用对用户因素还不够重视,地理信息资源的服务水平还比较低。针对该问题,本文对影响地理信息资源检索的用户因素进行分析,提出了兼顾用户因素的地理信息资源间关联关系计算方法。采用所提出的算法进行了地理信息资源检索实验,实现了对不同用户的资源推荐,促进个性化推荐在地理信息资源检索中的应用。

In the retrieval of geographic information resources, user factors will have a great impact on the retrieval results. However, the existing retrieval application of geographic information resources has not enough attention to the user factors, and the level of serv- ice of geographic information resources is still relatively low. Aiming at this problem, this paper analyzed the user factors which affect- ed the retrieval of geographic information resources, and put forward the calculation method of the relationship between the geographic information resources which taking into account the users factors. By the proposed algorithm, several retrieval experiments were car- tied out to realize the resources recommendation for different users and promote the application of personalized recommendation in geo- graphic information retrieval.
