The activities of the government can be described as reporting the feelings of the people (receiving infor-mation), making policies (processing information) and issuing government orders (sending out information). This is a typical course of information processing. If we can successively trail and scientifically measure this information course, we will be able to appraise the performance of the government in a scientific way. The development of government informatiza-tion and e-government is providing such a kind of appraisement for the government. The paper mainly discusses the possi-bilities of informetric analysis of the e-government. Methods for such analysis are also described.  相似文献

In this paper, we focus on applying sentiment analysis to resources from online art collections, by exploiting, as information source, tags intended as textual traces that visitors leave to comment artworks on social platforms. We present a framework where methods and tools from a set of disciplines, ranging from Semantic and Social Web to Natural Language Processing, provide us the building blocks for creating a semantic social space to organize artworks according to an ontology of emotions. The ontology is inspired by the Plutchik’s circumplex model, a well-founded psychological model of human emotions. Users can be involved in the creation of the emotional space, through a graphical interactive interface. The development of such semantic space enables new ways of accessing and exploring art collections.The affective categorization model and the emotion detection output are encoded into W3C ontology languages. This gives us the twofold advantage to enable tractable reasoning on detected emotions and related artworks, and to foster the interoperability and integration of tools developed in the Semantic Web and Linked Data community. The proposal has been evaluated against a real-word case study, a dataset of tagged multimedia artworks from the ArsMeteo Italian online collection, and validated through a user study.  相似文献

Cross-lingual semantic interoperability has drawn significant attention in recent digital library and World Wide Web research as the information in languages other than English has grown exponentially. Cross-lingual information retrieval (CLIR) across different European languages, such as English, Spanish, and French, has been widely explored; however, CLIR across European languages and Oriental languages is still in the initial stage. To cross language boundary, corpus-based approach is promising to overcome the limitation of the knowledge-based and controlled vocabulary approaches but collecting parallel corpora between European language and Oriental language is not an easy task. Length-based and text-based approaches are two major approaches to align parallel documents. In this paper, we investigate several techniques using these approaches and compare their performances in aligning English and Chinese titles of parallel documents available on the Web.  相似文献

中文本体的自动获取与评估算法分析   总被引:6,自引:0,他引:6  
在下一代互联网,即语义网中,信息模式建立在本体描述之上。由于手工构建本体是一项工作量巨大并且繁杂的任务,因而,能否自动构建本体正逐渐成为语义网使用的关键性要素。在这样的背景下,本文对比和借鉴了国内外本体自动获取的方法和思路,将中文领域本体的提取划分为文本预处理、本体抽取和本体关系获取三个阶段。接着,本文讨论了这三个步骤所涉及的算法,包括基于统计模式对文本抽词、基于奇异值分解从词—文档矩阵中提取本体、基于语义相似度对本体进行聚类等。对于本体自动获取的效果评估,本文提出了利用计算手工和自动两种方式得到的本体相似度来进行衡量的思路。  相似文献

语义Web的创建需要一套共同的标准概念体系,即本体(Ontology)。本体的构造手段仍然是以手工构造为主,效率和准确率都非常低,很容易导致知识获取的瓶颈。本文给出一个半自动化的需人工干预的本体学习体系结构,采用平衡的协作建模方式来构造语义Web中的本体;介绍了基于以上体系结构的本体学习的处理过程,并讨论了领域概念抽取,概念之间关系的抽取等关键技术。  相似文献

在介绍国内外相关研究现状的基础上构建了基于语义Web服务的虚拟图书馆体系架构,并详细阐述了体系架构的实现过程。该体系架构的平台采用SOA架构,采用完全开放的集成方式,保证了各种异构图书馆的开放集成;在功能上进行了语义扩充,其语义支持完全由平台中配置的领域本体来提供,可以根据各虚拟图书馆运作所涉及的各业务来进行配置可以实现更大规模和跨时空、跨领域的应用集成;同时,语义技术的采用还大大提高了平台的灵活性和可扩展性,业务的定义完全依赖各虚拟图书馆运作的要求,而与具体的应用集成系统无关,业务流程动态生成,使得业务的定义与执行完全独立。  相似文献
