中文摘要:
      数据与数据之间通过富含语义链接的方式形成了有价值的数据网络,在以语义网为核心的网络架构中,网络资源的语义化结构、细粒度描述、数据关联等特性对数据加工及利用提出了新的挑战,信息组织的处理对象及外延发生着变化,信息组织工具不断丰富且功能趋于统一。本文依据信息组织的不同功能和处理流程可以将其细分为资源层、元数据记录层、词表层,分别对各个层次的特点、变化及其未来发展进行分析,认为从文本中准确提取出反映语义含义的特征项是当前信息组织的关键问题,元数据集、知识组织系统成为词表的主要构成,知识组织系统呈现出描述对象概念化、语义关系多样化、描述语言形式化、数据开放关联性四大特点。图3。参考文献23。
英文摘要:
The network is regarded as the global data space in the semantic web architecture. The form of resource organization is transformed from file centered to data centered. The valuable data network is formed between data and data employing rich semantic links. The semantic structure, fine grained description and data correlation of network resources pose new challenges and possibilities for data processing and utilization. With the development of Semantic
web technology and the change of user demand for information, the objects and extension of information organization processing are constantly changing from document unit centered to knowledge unit centered. And information organization tools are constantly enriched and tend to be functionally unified and extend from controlled vocabularies such as classification schemes and thesaurus to knowledge organization systems such as semantic network and ontology to meet the needs of large scale, diversified and semantic information processing. In the process of development and evolution, how to abstractly summarize the process flow of information organization, and whether the roles played by different levels have changed? What are the essential links between different types of tools? What are the characteristics of the development of information organization tools? This paper focuses on those core issues and has a study using the method of literature analysis and system theory. According to the different functions and the process flow, information organization can be subdivided into resource layer, metadata record layer, and vocabulary layer. This paper makes a detailed and in depth analysis of the characteristics, changes and future development of each layer. The resource layer is the resource objects processed and can be divided into unstructured, semi structured or structured objects. The metadata record layer is formed after resource objects being described and indexed. Metadata set and knowledge organization system constitute the vocabulary layer, which is the schema of the data network, specifies the basic mode of information description, and clarifies the selected description elements and their corresponding value types and ranges. The analysis results show that the key problem of information organization is to extract the feature items which reflect the semantic meaning from the text accurately. Knowledge organization system aims at expanding the functions of information organization tools, expanding library resources to network resources, deepening the description and representation of resources from original document units to knowledge units, changing from human oriented construction to machine understanding, and gradually approaching user needs with finer descriptions. The knowledge organization system has four characteristics: conceptualization of descriptive objects, diversification of semantic relations, formalization of descriptive languages and open relevance of data. This paper systematically describes the process flow of information organization and clarifies the characteristics and future development requirements of resource layer, metadata record layer and vocabulary layer in the current stage of development. The deficiency is that there is no discussion on non information resource objects and information resource objects respectively. 3 figs. 23 refs.
