Introduction
Ever since they were created, search engines are used
to locate URLs on the web, according to the given
keywords. They have been a useful tool to researchers
all over the world, as the exponential growth of the
Internet became overwhelming. But along with the
evolution of the net, certain problems arise. Namely, a
good percentage of the URLs returned from the search
engines are either non-existing or they no longer carry
the required content. Searching the Internet can become
a costly and time consuming task because most wireless
devices connect to the Internet through a high-cost low-
bandwidth connection.
Typically web based search engines (Kamei et al.,
1997) use a web spider, which constantly collects new or
updated web pages, and a database in which the infor-
mation of the web page information (URL, words,
links, date, etc.) are archived. Most of these search en-
gines use a com

前言
自他们被创造了以后，查寻引擎使用找出URL网，根据特定
主题词。他们对全世界的研究员都非常有用。互联网的指数增长
迅速。
但与之俱来的，某些问题出现了。 即，从 查寻引擎返回的URL的百分比或者非存在或他们不再运载必需的内容。 因为多数无线电设备连接到互联网都通过高费用低带宽
连接，搜寻互联网可能成为一项昂贵和费时的任务。
典型地基于互联网的查寻引擎(Kamei， 1997)，经常收集新或更新网页和网页信息的一个数据库 (URL、词、链接、日期 等等)
大多这些查寻e引擎使用主题词和布尔操作工的组合
找出适合他们网页的数据库。 这运载也有些缺点。 例如，
没有办法使用布尔逻辑指定一关键词的重要性。 此外，
由于用于网查寻引擎的句法的非均匀性，同一次询问在
不同的查寻引擎也许导致不同的结果。 所以， 用户被迫使熟悉每一个。
