荷兰阿姆斯特丹自由大学Frank van Harmelen回答德国著名IT杂志C'T记者的提问:什么是SW的“killer application"?

[@more@]Q:All great technological inventions and milestones are marked by the
advent of a killer application. What could/will be the Semantic Web's
killer application? Will there be one at all?

A: I find the perennial question for the "killer app" always a bit
naive. For example: can we agree that the widespread adoptation of XML is
an important technical innovation? But what was XML's "killer app"? Was
there a single one? No. There are just many places where XML facilitates
progress "under the hood"? Semantic Web technology is primarily
*infrastructure* technology. And infrastructure technology is under the
hood, not directly visible for users. You will simply notice websites
becoming more personalised (because under the hood semantic web
technology allows your personal interest profile to be interoperable
with the data-sources of the web-site), or you will simply notice search
engines doing better clustering of results (because under the hood they
have classified search results in a meaningful ontology), or you will
simply notice your desk-top search tool being able to link author names
of documents with email addresses in your address-book (because under
the hood, these data-formats have been made to interoperate by exposing
their semantics), but none of these applications will have "Semantic Web
technology" written on their interface. Semantic Web technology is like
Nikasil coating in the cylinders of your car: very few car drivers are
aware of it, but they are aware of reduced fuel consumption, higher top
speeds and extended lifetime of the engine. Semantic Web technology is
the Nikasil of the next generation of humanfriendly computer
applications that are being developed right now.

问:所有大的技术发明和里程碑都是以其杀手锏应用(Killer application)的出现为标志的。语义网的杀手锏会是什么?究竟有没有?

答:我发现关于“杀手锏应用(killer app)”这一反复问及的问题总是有些幼稚。举个例子:我们同不同意 XML的广泛采纳是一项重要技术创新?但谁是XML的“killer app”?这样一个“killer app”存在吗?不。存在的只是许多场合,XML 在这些场合下能够“在背后”起到促进作用。语义网技术主要是基础设施技术,而基础设施技术是存在于背后、并非用户直接可见的。你所能感受到的只是诸如网站变得更人性化了(因为背后存在语义网技术,你的个人兴趣概要可以与网站的数据源进行互操作)、搜索引擎在结果聚类方面做得更好了(因为搜索引擎在背后采用具备含义的本体来对搜索结果加以分类)或者桌面搜索工具能够把文档作者的姓名与你的地址簿里的 Email地址联系起来了(因为这些数据格式在背后通过暴露其语义来实现互操作),但这些应用不会在其界面上注明“语义网技术”。语义网技术就像是汽车汽缸上的Nikasil涂层[1]:虽然很少有司机去注意它,但司机能够察觉到燃料消耗的减少、最高时速的提升以及引擎寿命的延长。语义网技术就是目前正在开发着的、下一代人类友好的计算机应用的Nikasil涂层。

译注:Nikasil涂层是Yamaha公司的一种专利技术。Nikasil是一种镍矽碳化物,将它电镀在汽缸上可以解决铝硅发动机耐磨性问题。
