Book Abstract

万维网已经成为人们获取信息的主要渠道之一,深刻影响到人类社会生活的各个方面:人们在Web上浏览新闻、搜索信息、买卖商品及服务。然而,目前的万维网是面向人而不是面向机器的。换句话说,人可以理解万维网上的内容,而机器则不能理解。随着万维网上的内容越来越多(据Google的官方Blog公布的数据,目前Google索引了IT个URL),人们准确、快速、全面获取到信息也越来越难。
对此,Www、URIs、HTTP和}tTMI,的发明人Berners-Lee提出了语义网概念。他认为“The Semantic Web will bring structure to the meaningful contentof web pages。creating an environment where software agents roaming from pageto page can readily carry out sophisticated tasks for users”自从提出语义网之后,语义网得到了学术界和工业界的重视。Gartner认为企业语义网是3个具有影响力的万维网技术之一。许多语义网公司,如Siderean、SandPiper、Intellidimension等在兴起。一些大公司,如Adobe、HP、IBM、Nokia、Oracle、’Vodaphone等纷纷对语义网技术进行研发。一些国家和国际组织,如英国、欧盟、美国也投入资金资助相关研究。
语义网是关于万维网的元数据网。数据一直是语义网的核心问题,Berners-Lee曾经公开表示,他认为对语义网更准确的名称应该是数据网(data web)。语义网存在及互联的目的是使得计算机能够自动处理、集成来自不同数据源的数据,而不仅仅是为了让计算机能够正确显示。为了实现让机器或设备能够自动识别和处理网上数据,需要在内容中加入标记,即需要采用标记语言。考虑到适应不同领域的标记需要,标记语言必须是灵活、可扩展的。为了实现此目标,研究和制定在万维网上发布能够帮助计算机理解内容的设施、技术和规范成为迫切需要解决的问题。
对此,研究人员、标准化组织包括互联网工程任务组和W3C等都致力于增强、扩展语义网能力,在研究、制定以及部署能够共享语义的语言以及工具方面进行了大量工作。这些语言为语义互操作提供了基础。1997年,W3C定义了资源描述框架规范RDF。此后,相继提出了RDFS/OWL、GRDDL、RDFa等规范或建议规范。研究人员也开发了许多工具,如Kowari、RDFLib、Jena、Sesame、Protege、SWOOP等。w3C将其中的部分技术标准化,形成了一些标准,包括资源描述框架RDF、RDFS/0WL等。
Introduction

国家重点基础研究发展计划项目“语义网格的基础理论、模型与方法研究”从2003年开始围绕“规范重构,语义互联,智能聚融”这三个科学问题系统地探索了未来互联环境的语义基础问题,取得了一系列成果,本书是其中的重要成果之一。
自从计算机诞生以来,数据管理一直是计算机科学的核心问题之一。特别是随着信息技术的快速发展与普及,个人与社会每时每刻都在大量产生数据。人类将生活在一个充满数据的世界里。如何对海量数据进行有效管理就成为一个重要的研究问题。
要实现海量数据的有效管理首先要解决语义问题。有效利用海量数据更加依赖语义问题的解决。计算机科学乃至信息科学的许多问题在本质上都可以归结为语义问题。虽然人们自觉不自觉地都在使用语义,但不同的领域对语义有不同的认识。例如,语义网研究领域希望对万维网中的数据增加机器可理解的语义,以使机器能快速、准确地从万维网上获取全面有用的信息并进行自动处理。但大量加上标注的数据如何进行管理就成为了一个新的问题。传统的数据库模型难以适应如今的网络数据管理,从而研究规范组织的语义网数据模型就成为问题的核心。
该书结合作者的研究体会,吸收了新的技术和方法,大跨度地阐述了语义数据管理的技术和研究问题,涉及诸如数据模型、抽取、分类、存储、检索、呈现等。适应了语义网数据管理开发、应用和研究的需要。
该书内容丰富,希望读者能从中获得对语义数据管理的知识,对相关研究有所启示。故向读者郑重推荐。
