一种基于XML的Web数据挖掘方法

XML的出现为基于Web的数据挖掘带来了便利,但是目前很多网站都是用HTML构建的,要真正做到高效准确的挖掘数据非常困难.介绍一种方法充分利用XML的优点对HTML描述的网站信息进行挖掘,并结合实例说明了这种方法.     

基于模板类的动态网页的实现

网页界面设计和程序的分离是简化网页维护的必由之路。本文在对网页界面设计和程序的分离中的问题进行分析的基础上，提出将模板技术应用于动态网页中来实现网页界面设计和程序的分离。当要对网页的界面进行变动时，只需修改HTML模板，简化了网页的维护。     

PHP录入页面动态从数据库中提取数据的实现

用PHP制作动态Web页面时,在提交服务器之前,让PHp根据用户在当前页面上录入的某字段的值,立即从数据库中取出相关的其他字段的值并显示到当前页面上,是PHP程序开发中的难点.本文以一个具体实例,详细介绍了怎样将两个HTML内嵌式语言PHP和JavaScript巧妙结合起来解决这个难点的具体方法.     

基于本体论的Web信息抽取

以本体论为基础，以所要提取的信息的层次结构作为信息提取的路径，定义了Web页面的信息项本体，并自动解析生成Web页面的结构本体．通过对这两个本体进行对比，构造了一种归纳学习算法来半自动地生成信息提取规则，对Web页面的信息提取具有较高的效率．     

Automating Content Extraction of HTML Documents

Web pages often contain clutter (such as unnecessary images and extraneous links) around the body of an article that distracts a user from actual content. Extraction of useful and relevant content from web pages has many applications, including cell phone and PDA browsing, speech rendering for the visually impaired, and text summarization. Most approaches to making content more readable involve changing font size or removing HTML and data components such as images, which takes away from a webpages inherent look and feel. Unlike Content Reformatting, which aims to reproduce the entire webpage in a more convenient form, our solution directly addresses Content Extraction. We have developed a framework that employs an easily extensible set of techniques. It incorporates advantages of previous work on content extraction. Our key insight is to work with DOM trees, a W3C specified interface that allows programs to dynamically access document structure, rather than with raw HTML markup. We have implemented our approach in a publicly available Web proxy to extract content from HTML web pages. This proxy can be used both centrally, administered for groups of users, as well as by individuals for personal browsers. We have also, after receiving feedback from users about the proxy, created a revised version with improved performance and accessibility in mind.

利用HTML标签筛选网页分类样本

互联网的Web网页中蕴藏着内容广泛、形式各异的信息资源,通过网页的自动分类可以更好地对其内容进行组织和管理,加快信息检索的速度。在训练网页分类器时,对网页样本集进行有效地筛选有可能改善分类器的性能。文中利用HTML文档的结构特点,基于标签对网页样本集进行筛选,从中去除索引型和表格型网页,实验表明,这种方法有一定的可行性。     

HTML^＋＋—一种增强WWW智能的途径

There are problems to access information from the Web. It is the HTML's weakness in knowledge representation and the WWW's shortage in knowledge handling. This paper presents a ob-ject-oriented hyper text makeup language－HTML++ , which is an enhanced version of HTML, in order to optimize the information structure of hyper text and provide it the capability of semantantic representation. HTML++ provides WWW a practicable approach of importing the capability of information processing such as reasoning. This makes it posstble accessing information in an ad-hoc, direct, precision and customized style.
