基于Web Services的异构数字地图资源检索算法

Research on Retrieval Algorithm of the Digital Map Resources Based on Web Services

从数字地图资源互联互检的现状出发,研究了传统异构数据源统一检索的3种模式,提出了基于Web Services的数字地图资源检索模式,设计了基于Web Services的数字地图资源统一检索结果融合算法和元数据更新算法,完成了一个基于Web Services的数字地图资源检索原型系统,对数字地图资源统一检索系统的开发具有借鉴意义。

Starting from the present situation of research on information retrieval in digital map resource, this paper analyzed the characteristics of the model unified retrieval of traditional heterogeneous data resources, proposed a digital map resource unified retrieval service model based on Web Services, designed the results fusion algorithm and metadata update algorithm of the digital map resources retrieval system based on Web Services in detail, and completed a digital map resources retrieval prototype system based on Web Services. This research is of great significance for the development of the digital map resources retrieval system.
