中文简介:
在Tim Berners Lee,James Hendler和Ora Lassila发表的开创性文章发表十二年后,语义网仍然明显缺乏“令人惊叹的因素”,它阐述了以动态和大规模代理互操作为特征的语义Web的愿景。存在许多SW应用程序,但是它们的特征通常是在编译时将很少的数据源放在一起以驱动一些相对简单的用户功能。在许多情况下,与使用传统技术构建的系统相比,很难确定“语义”为这些应用提供的竞争优势。当然,有人可能会认为这不一定是一个问题:一个地区的成功是以其学术活力及其对商业和社会的影响来衡量的。但是,我认为这里确实存在一个问题,在我的演讲中,我将通过研究如何在我们的社区中使用语义概念来分析这些问题,强调该术语的生产性和非生产性用法,特别是描述不同的可以有效利用语义为应用程序提供附加值的方法。关键信息是,尽管有许多方法可以利用语义来开发更好的功能,但作为一个社区,我们需要对使用语义提供的价值主张有更好的理解(从根本上和实际上)。如果没有这样的理解,我们就有可能无法充分利用我们正在开发的技术及其为我们创造的机会。
课程简介: Twelve years after the publication of the seminal article by Tim Berners-Lee, James Hendler and Ora Lassila, which expounded the vision of a Semantic Web characterised by dynamic and large scale agent interoperability, the Semantic Web still distinctly lacks a “wow factor”. Many SW applications exist, but too often they are characterised by few data sources put together at compile time to drive some relatively simple user functionality. In many cases it is difficult to identify the competitive advantage that ‘being semantic’ affords these applications, compared to systems built using conventional technologies. Of course, one could argue that this is not necessarily a problem: the success of an area is measured in terms of its academic vitality and its impact on commerce and society. However, I would argue that there is actually a problem here and in my talk I will analyse these issues by examining how the notion of semantics is used in our community, highlighting the productive and unproductive uses of the term, and in particular describing the different ways in which semantics can be effectively exploited to provide added value to applications. The key message is that while there are many ways to exploit semantics to develop better functionalities, as a community we need to develop a better understanding (both fundamentally and pragmatically) of the value proposition afforded by the use of semantics. Without such understanding there is a risk that we will fail to take full advantage of the technologies that we are developing and the opportunities they create for us.
