In this paper a novel ontology-based data semantic fusing frame named ODSF is introduced, the basic element of ODSF is dataset its semantic is obtained by the mapping between the domain ontology and dataset. ODSF adopts nested relation model to represent the schema information of dataset, and realizes the data fusing from coarse-grained level to the small-grained level by wrapping the datasets registered in virtual database as a new dataset. We also present the semantic model of ODSF, query executing process and algorithm of virtual database, so ODSF can provide the semantic supported and QoS supported data access for user. The experiments demonstrate our work and show the feasibility and effectiveness of ODSF and its key techniques.

本文提出了基于本体的语义数据容融合方法ODSF；该方法中的基本元素是数据对象，通过数据对象和领域本体之间的映射关系来表达数据对象的语义，使用嵌套关系模型来表达数据对象的模式信息，通过一个网格节点中集成的所有数据对象作为下一个节点的数据对象来实现数据资源由粗到细的融合；定义了ODSF的语义模型，给出了虚拟数据库的查询执行过程和算法，可以为使用者提供具有语义支持、服务质量保障的数据访问服务；通过原型系统验证了ODSF中理论和关键技术的正确性和可行性。

Peacock and theory of Talcott Parsons, the Latent Pattern-Maintenance（Cultural-Motivational System） of the AGIL schema.

Peacock所强调的&整体论&和Talcott Parsons所提出的AGIL理论之一的潜在模式维持的概念，采用了人类学、社会学、土壤学、社会心理学、传播学理论及其研究法解释支持捡骨重葬行为背后的死的传统理念模式。

The data model is the data source for the integrated mining which is built by using Snow Flake Schema. The integrated mining model consists of local mining and global mining. That is to say, firstly, monitoring cell mining, point mining and monitoring data mining are fulfilled respectively, then global mining model is run to opimize the monitoring process. The paper brings forward how to build up these models and the framework, and what variables should be delivered.

首先，采用雪花结构建立了数据模型构架，为流程挖掘提供数据底层；然后建立了监测流程综合挖掘模型构架，给出了监测单元挖掘、监测点位挖掘和监测数据挖掘，以及综合挖掘的模型函数和参数，以局部优化和全局优化的思路实现了土壤环境监测全流程优化。

Using stratificational grammar of structuralist linguistics for reference, the first chapter analyses the conventional categories and schema, principle, character of news structure and relations between them and cognition. Based on the analysis of news examples, the chapter draws the conclusions: first, news discourse consists of six basic categories of headline, lead, event, consequence/reaction, background and comment.
