俗语说：大事不决问老婆，小事不决问Google。验证了Google的强大，无处不在，无所不能。在信息产业（Information）里，Google是行业老大，它的使命宣言是：把全世界所有的知识都组织起来。励德爱思唯尔排在第二，但爱思唯尔拿什么与Google竞争呢？

我觉得，在爱思唯尔诸多新产品中，illumin8代表了最先进的方向。Google的关键词搜索是第一代搜索，illumin8是基于semantic技术的搜索，这代表着搜索领域“先进技术的前进方向”。我在“双清论坛”上，向期刊界的同行们简单介绍过。

这也代表了爱思唯尔与Google在根本战略方面的不同：Google的目标是服务于一切人，爱思唯尔的目标服务好科研人员。还有一个根本区别，就是爱思唯尔拥有900万篇全文文献的版权——这个世界上每年出版的科研论文中，四分之一以上发表在爱思唯尔的期刊上。Google没有版权，没有全文，这就是它最近为什么输了官司，支付了十几亿美元版税给培生等出版公司。

什么是第二代搜索？什么是illumin8？它与Google有什么区别？最近有一篇小文章讲得很清楚，部分引用如下：

Semantic search said to surpass Google
R. Colin Johnson
EE Times

Serious research has a new tool called illumin8 that harnesses semantic searches, which understand the meaning of queries. Unlike the free Google search engine, which merely matches the words in a query against Web pages containing those keywords, Elsevier's illumin8 uses a thesaurus with a half-million pre-defined technology terms to associate semantics--the meaning of the phrases--with queries.

The new search engine is not free, but it does run on a Web page, permitting the user to enter queries very similar to those they are used to doing at Google, Yahoo or any of the keyword search engines. The difference comes when you press the search button. Rather than getting an immediate list of results ranked by popularity, illumin8 takes a few seconds to determine the meaning of your query by comparing it against its precompiled semantic database. Elsevier's crawler algorithm is constantly searching six billion Web pages, three million science and technical journal articles, 33 million reported scientific results, and 21 million patents, which it compiles into 1.1 billion semantic extractions of related concepts.

After determining the semantic extractions relevant to your query, it then presents a summary of its results organized in separate panes of a full-screen window, sorted by organization, approach, benefit, author/inventor, company and product. Each of these panes shows a list of items, each displaying how many individual records are associated with each item.
