路西登记了,但是皮特有点不满:“给我些详细资料”, 这是我所有资料。(当然,皮特不能拒绝计划,尽管它不在名单中, 在晚上他让他的代理解释。)
Expressing Meaning(表达方式 )
Pete and Lucy could use their agents to carry out all these tasks thanks not to the World Wide Web of today but rather the Semantic Web that it will evolve into tomorrow. Most of the Web's content today is designed for humans to read, not for computer programs to manipulate meaningfully. Computers can adeptly parse Web pages for layout and routine processing?here a header, there a link to another page?but in general, computers have no reliable way to process the semantics: this is the home page of the Hartman and Strauss Physio Clinic, this link goes to Dr. Hartman's curriculum vitae.
皮特和路西能让他们的代理处理这些任务,不但要感谢今天的互联网,还要感谢明天将会出现语义网。今天大部分网页内容是设计给普通人读的,不是专给程序来操作。通常计算机能敏捷分隔网页和常规地处理主题,并可以把它连接到另一个网页,但是计算机并没有一种可靠的方法处理语义:这是Hartman和Strauss医务所的主页,连接可以带到Hartman医生的简历的网页。
The Semantic Web will bring structure to the meaningful content of Web pages, creating an environment where software agents roaming from page to page can readily carry out sophisticated tasks for users. Such an agent coming to the clinic's Web page will know not just that the page has keywords such as "treatment, medicine, physical, therapy" (as might be encoded today) but also that Dr. Hartman works at this clinic on Mondays, Wednesdays and Fridays and that the script takes a date range in yyyy-mm-dd format and returns appointment times. And it will "know" all this without needing artificial intelligence on the scale of 2001's Hal or Star Wars's C-3PO. Instead these semantics were encoded into the Web page when the clinic's office manager (who never took Comp Sci 101) massaged it into shape using off-the-shelf software for writing Semantic Web pages along with resources listed on the Physical Therapy Association's site.
