中文摘要: 随着对地观测软硬件的发展,传感器观测与数据处理技术也正从单机、计算机网络向传感网方向发展。然而在传感网环境下如何将异质观测数据进行融合、异质的网络服务进行集成,实现对多传感器资源的共享和互操作已经是当前研究热点。本课题以OGC不同类型和版本的网络服务信息模型为研究对象,针对当前不同类型网络服务间还不能进行直接访问和互操作,同类型不同版本网络服务通过版本协商机制进行集成访问存在的版本不一致和可靠性差的问题,提出了一种基于动态语义模式匹配和自动信息提取和智能数据融合的异构网络服务集成方法。主要研究异构网络服务信息模型的精确匹配、异构网络服务实例的自动转换和数据融合,研究成果可以提高地学传感器资源的精确发现、高效访问能力,可直接应用于我国"天地图"网站应用中,为提升我国地理信息服务集成能力,促进地理信息资源的共享和高效利用奠定基础,具有重要学术价值和现实意义。

英文摘要: With the development of hardware and software for earth observation, sensor observation and data processing technology is also from the stand-alone, computer networks to the direction of the sensor network. However, in the sensor network environment, how to realize the integration of heterogeneous observational data, integration of heterogeneous network services, to achieve multi-sensor resource sharing and interoperability is the current research focus. The project apply different types and versions of OGC web service information model for the study, due to directly access and interoperate between different types of network services can not be achieved currently, different versions of the same type of network services through a consultation mechanism to access in an integrated way cause the problem of version of the inconsistency and the problem of poor reliability, therefore, we propose an approach to integrate heterogeneous network service based on dynamic schema matching and automatic information retrieval and intelligent data fusion. The main research contents include: the exactly schema matching for heterogeneous web service information model , heterogeneous web service instance automatic conversion and data fusion, the research results can improve the ability of geo-sensor resources' precise discovery,
