摘　　要：为消除协同标注系统中标注信息的封闭性,为标注信息引入统一的数据元模型地理标识语言GML。为减少标注信息的异构性和局部自治性,引入模式匹配技术对GML模式中元素的相似度进行匹配计算。在一般模式匹配算法的基础上引入了动态权值调配函数,并根据规则之间的优先关系将规则组合起来,完成元素相似度的计算。通过标注信息模式匹配,协同标注系统用户在协同工作活动中可直接、透明的获取标注信息之间的相似关系,更高效的在协同工作环境下进行信息交流。For removing the closure characteristic of attribute data of plotting information, it is necessary to adopt a unified meta-data model GML （geography markup language） to represent the attribute data of plotting information. For reducing the heterogeneity and local-autonomy, it is necessary to adopt schema matching technology to calculate the similarity of element pairs in GML schema. Based on the general schema matching, the dynamic weight modulating function are adopted. After organizing the criterions by dynamic weight modulating function, the similarity of element pairs is figured out. The result of experiment indicates that schema matching technology can effectively accomplish the task of plotting information matching, and then have provided effective way of communication using plo- tting, then it basically achieves our elementary goals. Then the users can directly and transparently get the similarity relationship of plotting information in the collaboration actions; thus, they can communicate more efficiently in cooperative working environment.
