语义网的应用领域(Semantic Web Application Areas)

今天又看了一片介绍语义网的论文，下面是一些笔记。 有效的知识管理被定义为是组织团体间竞争的关键。传统的知识管理现在正面临着互联网带来的一些问题；信息超载、低效的关键字查询、不同类型的信息整合和地理上分布的内部网问题，(to name but a few?)。这些问题将会被现代的语义网技术所解决。Ontoknowledge项目在通过推动本体进化来寻找内容驱动的知识管理解决方案中起到了重要作用。它用语义网技术的力量促进了知识管理的发展。 Efficient knowledge management has been identified as key in maintaining the competitiveness of organizations. Traditional knowledge management is now facing new problems triggered by the web; information overload, inefficient keyword searching, heterogeneous information integration and geographically-distributed intranet problems, to name but a few. These problems will be tackled by the modern technology known as Semantic Web Technology ([Fensel, 2001] and [Fensel et al., 2002]). The Ontoknowledge2 (OTK) project (cf. [Fensel et al., 2000]) is an important player devoting itself to finding content-driven knowledge management solutions through evolving ontologies. It employs the power of the Semantic Web Technology to facilitate knowledge management. Ontoknowledge操作的全部层次工具环境： The complete layered tool environment of Ontoknowledge operates:  OntoExtract和OntoWrapper从英特网或内部网里的特定域提取出未结构化的(注：OntoExtract处理)和已结构化的(注：OntoWrapper处理)文本信息。这些被提取出来的信息被存入RDF-DB中(这种数据库叫Sesame)，这些数据能够被OntoEdit工具编辑。最后，RQL(RDF查询语言)推理引擎允许这种数据库接受查询和把结果通过RDF Ferret用可视化的方式展示给用户。 OntoExtract and OntoWrapper extract unstructured and structured textual information sources from specified domains on the Internet or Intranet. The extracted information is pumped into the RDF-DB (Sesame), where it can be edited with the OntoEdit tool. Finally, the RQL (RDF querying language) reasoning engine allows for the querying of this database and delivers results to a user through RDF Ferret which may be visualized by Spectacle. 在电子商务中领域： 本体映射：整合商业文档 Ontology Mappings: Integrating Business Documents • Vocabularies that mostly represent sets of terms, sometimes enriched with topology. • Business documents that mostly represent part-breakdown of documents into elements and their ontological models that contain a shallow concept hierarchy but a number of constraints on element values. • Processes ontologies that contain a limited number of terms corresponding to timepoints, activities, objects etc., but a rich set of temporal axioms. 一种RDF映射技术RDFT现在被开发出来用于描述、重用和执行这些映射。特别的，RDFT提供一个整合机构，一个叫做桥的特定的元-本体映射结构，和一个将这些映射图转换为XSLT的技术。 An RDF mapping technology RDFT is now being developed to represent, reuse and execute these mappings [Omelayenko et al, 2002]. Specifically, RDFT provides an integration architecture, a mapping meta-ontology that specifies the mapping constructs called bridges, and the technology for map interpretation and translation to XSLT. 本体版本：内容标准 Ontology Versioning: Content Standards Web服务(Web Services)： 语义网技术一直处于它的早期阶段。我们一直聚焦在建立它的一些基础 —— 和大多数静态的 ——基础结构。下一步就是要开发一些活跃原件来使用这些基础设施，为用户提供智能的服务。 Semantic Web technology is still in its early stages. We are focusing on building its basic - and mostly static - infrastructure. The next step will be to produce active components that use this infrastructure to offer users intelligent services. |
