【摘要】：语义物联网(SemanticWebofThings)是信息生态系统中人、机、物、事、网、时这六个基本要素及交互关系的整体体系结构,因此语义物联网中的物不仅仅是传统意义上物到物之间的网络,而是社会化网络中物与物、物与人、人与人之间的互联,在互联的过程中会产生许多新闻事件。本文着手于语义物联网中的"事"和"网"这两方面,新闻事件存在的动态实时性的特点并且网络上的新闻事件都是基于超链接架构,网站的编辑者是按照个人意愿进行相互链接而不是有效的关联链接,导致用户经常找不全自己所需的新闻信息,因此在超链接上添加语义因子后扩展为语义链接构成语义链网络进行新闻事件的相关链接,来解决上述问题。本文首先对语义链网络的现状进行了分析,在对语义链网络的相关理论和技术进行阐述的基础上,重点提出了基于新闻事件的语义链网络构建系统的框架,其语义链网络构建流程主要包括:(1)数据收集包括网页的收集、解析及存储,通过搜索引擎对大量新闻事件进行收集;(2)数据预处理包括语义元素提取、资源表示及关联关系的挖掘,主要是对收集到的新闻事件网页进行语义元素提取,并利用E-FCM表示新闻事件的语义节点,再根据关联关系挖掘算法获得语义节点间的语义链;(3)构建了基于新闻事件的语义链网络;然后对语义链网络构建系统进行分析与设计,设计的主要模块有:数据收集模块、数据处理模块、语义链网络构建模块及语义链网络操作模块;最后实现了系统的主要功能模块并分别对传统超链接网络和语义链网络做了相关实验。本文设计并实现了基于新闻事件的语义链网络构建系统。通过实验及对比分析可知:用户能够利用构建好的语义链网络,在查询所需新闻事件的查准率、召回率及F值等方面都有不同程度的提高,使得用户能够获得更丰富更全面的新闻信息。以弥补用户使用传统的超链接网络经常找不到所需求的相关新闻信息这一问题。
[Abstract]:Semantic information networking (SemanticWebofThings) is in the ecological system of people, machine, material, business, network, the whole architecture of these six basic elements and interactions, so semantic objects in Internet of things is not only the traditional sense to the physical network between objects and objects, but in social network,. With the Internet, between people, in the interconnection process will produce many news events. This paper starts from the semantics of the Internet of things "things" and "net" of these two aspects, news events exist the characteristics of dynamic real-time and network news events are hyperlink frame based on Web the editor is not associated with effective links linked according to the wishes of the individual, lead users often find insufficiency to news and information, thus adding semantic factors in hyperlinks on extended semantic link structure semantic chain network news. Related links, to solve the above problems. Firstly, the status of the semantic link network is analyzed in this paper, the theory related to the semantic link network and technology, puts forward the framework for constructing the semantic link network news events based on the process of building the semantic chain network (including: 1) data collection including web collection, analysis and storage, based on a large number of news search engine collected; (2) data preprocessing including semantic elements extraction, mining resource representation and relevance, is mainly to collect news events "semantic elements extraction, semantic representation and the use of E-FCM node news events then, according to the association rule mining algorithm to obtain semantic semantic link between nodes; (3) to construct a semantic chain network based on news events; then the semantic link network analysis and system construction The main design, module design, data collection module, data processing module, module and semantic link network operation module for constructing the semantic link network; the final realization of the main function modules of the system are the traditional hyperlink network and semantic link network experiments. This paper presents the design and implementation of system construction of semantic link network news based on the event. Through the analysis of experiment and comparison, the user can use semantic link network is constructed, the precision required for news events in the query, recall and F-measure aspects have different degrees of improvement, so that the user can get richer and more comprehensive information. As a hyperlink network for users the traditional often can not find the problem related news and information needs.
