摘要 个人计算机技术的不断发展使得传统的桌面检索和排序方式越来越不能满足用户的需求。本文给出了一种语义桌面环境下的桌面资源索引排序模型,并在PageRank和数据库的权威度传递图理论基础上提出了一种索引排序算法。与传统的检索排序方式相比,本方法能更好地反映查询与检索结果之间的相关程度以及结果的重要程度次序。实验表明,本方法在时间效率和空间占用方面均能适应目前普通个人计算机的处理能力。本方法在语义桌面以及桌面搜索等相关领域有着广泛的应用前景。 With the development of computer science and the technology of PC, the traditional desktop searching and ranking method could not satisfy the requirement of user. This paper provides a ranking model for the desktop resource searching based on metadata in the environment of semantic desktop, then after the study of PageRank algorithm and the theory of authority transfer graph, a new index ranking algorithm is provided. The experiment proves that this ranking method could effectively reflect the priority of the researching results and the relationship between the query and the results. The time and space efficiency of this method could also meet the capability of today＇s normal computers. This method could work for semantic Web, desktop searching and other correlative domains.
