网页文字随心用

许多朋友可能都遇到过这样的问题,想阅读网页中的文字,可字体不是太小就是太大,看起来很不舒服。想单独复制网页中的文字,可有的网页禁止使用右键复制命令,有的网页文本分隔混在图片中,复制起来很麻烦,有的网页文本在复制后往往会夹杂着各种乱七八糟的格式符号等等。其实只需用     

个性化IE地址栏字体

我们知道,在Internet Explorer浏览器中,可以在 “Internet选项”中设定Web网页字体和纯文本字体,这 样就可以以自己独特的风格浏览网页,另一方面也缓解了 因显视器分辨率而引起的阅读问题。可还有一点不完美, 那就是Internet Explorer地址栏字体如何修改呢?到底     

Flash移花接木

网页中虽然有很多好看的Flash动画，但是他们都是存在网页中的文件无法利用鼠标右键功能直接进行保存。每次只能看着心爱的Flash在网页中闪烁，无法保存到硬盘中欣赏，不过，当笔者找到“Flash移花接木”的时候一切问题就可以迎刃而解。“Flash移花接木”可以保存已经下载到IE缓存中的文件，还可以替换Flash中的图片达到“移花接木”的效果。

基于MMTD网页挂马响应的研究

当今网络中通过网页来种植木马的现象已很普遍。利用网页来传播木马技术就是将木马的域名隐藏在网页里,用户在浏览网页时,隐藏在网页中的木马就会被种植到用户的系统中。因此如果被访问的网页嵌入了木马的域名,那么当网络用户发出链接请求响应时,网络的响应将变得异常。基于上述原因,本文从链接请求响应次数的角度,来判断网页中是否藏有木马域名。首先简介木马技术,网页挂马技术和中介的基本概念,然后给出检测函数y=f(x)以及MMTD在检测木马上的应用,最后给出具体检测算法。

A text mining approach for automatic construction of hypertexts

The research on automatic hypertext construction emerges rapidly in the last decade because there exists a urgent need to translate the gigantic amount of legacy documents into web pages. Unlike traditional ‘flat’ texts, a hypertext contains a number of navigational hyperlinks that point to some related hypertexts or locations of the same hypertext. Traditionally, these hyperlinks were constructed by the creators of the web pages with or without the help of some authoring tools. However, the gigantic amount of documents produced each day prevent from such manual construction. Thus an automatic hypertext construction method is necessary for content providers to efficiently produce adequate information that can be used by web surfers. Although most of the web pages contain a number of non-textual data such as images, sounds, and video clips, text data still contribute the major part of information about the pages. Therefore, it is not surprising that most of automatic hypertext construction methods inherit from traditional information retrieval research. In this work, we will propose a new automatic hypertext construction method based on a text mining approach. Our method applies the self-organizing map algorithm to cluster some at text documents in a training corpus and generate two maps. We then use these maps to identify the sources and destinations of some important hyperlinks within these training documents. The constructed hyperlinks are then inserted into the training documents to translate them into hypertext form. Such translated documents will form the new corpus. Incoming documents can also be translated into hypertext form and added to the corpus through the same approach. Our method had been tested on a set of at text documents collected from a newswire site. Although we only use Chinese text documents, our approach can be applied to any documents that can be transformed to a set of index terms.     

基于遗传算法的主题爬虫

针对目前主题网络爬虫搜索策略难以在全局范围内找到最优解,通过对遗传算法的分析与研究,文中设计了一个基于遗传算法的主题爬虫方案。引入了结合文本内容的PageRank算法;采用向量空间模型算法计算网页主题相关度;采取网页链接结构与主题相关度来评判网页的重要性;依据网页重要性选择爬行中的遗传因子;设置适应度函数筛选与主题相关的网页。与普通的主题爬虫比较,该策略能够获取大量主题相关度高的网页信息,能够提高获取的网页的重要性,能够满足用户对所需主题网页的检索需求,并在一定程度上解决了上述问题。     

Automatic image–text alignment for large-scale web image indexing and retrieval

In this paper, an automatic image–text alignment algorithm is developed to achieve more effective indexing and retrieval of large-scale web images by aligning web images with their most relevant auxiliary text terms or phrases. First, a large number of cross-media web pages (which contain web images and their auxiliary texts) are crawled and segmented into a set of image–text pairs (informative web images and their associated text terms or phrases). Second, near-duplicate image clustering is used to group large-scale web images into a set of clusters of near-duplicate images according to their visual similarities. The near-duplicate web images in the same cluster share similar semantics and are simultaneously associated with a same or similar set of auxiliary text terms or phrases which co-occur frequently in the relevant text blocks, thus performing near-duplicate image clustering can significantly reduce the uncertainty on the relatedness between the semantics of web images and their auxiliary text terms or phrases. Finally, random walk is performed over a phrase correlation network to achieve more precise image–text alignment by refining the relevance scores between the web images and their auxiliary text terms or phrases. Our experiments on algorithm evaluation have achieved very positive results on large-scale cross-media web pages.     

Exploiting link structure for web page genre identification

As the World Wide Web develops at an unprecedented pace, identifying web page genre has recently attracted increasing attention because of its importance in web search. A common approach for identifying genre is to use textual features that can be extracted directly from a web page, that is, On-Page features. The extracted features are subsequently inputted into a machine learning algorithm that will perform classification. However, these approaches may be ineffective when the web page contains limited textual information (e.g., the page is full of images). In this study, we address genre identification of web pages under the aforementioned situation. We propose a framework that uses On-Page features while simultaneously considering information in neighboring pages, that is, the pages that are connected to the original page by backward and forward links. We first introduce a graph-based model called GenreSim, which selects an appropriate set of neighboring pages. We then construct a multiple classifier combination module that utilizes information from the selected neighboring pages and On-Page features to improve performance in genre identification. Experiments are conducted on well-known corpora, and favorable results indicate that our proposed framework is effective, particularly in identifying web pages with limited textual information.     

基于支持向量机与无监督聚类相结合的中文网页分类器

提出了一种将支持向量机与无监督聚类相结合的新分类算法,给出了一种新的网页表示方法并应用于网页分类问题。该算法首先利用无监督聚类分别对训练集中正例和反例聚类,然后挑选一些例子训练SVM并获得SVM分类器,任何网页可以通过比较其与聚类中心的距离决定采用无监督聚类方法或SVM分类器进行分类。该算法充分利用了SVM准确率高与无监督聚类速度快的优点。实验表明它不仅具有较高的训练效率,而且有很高的精确度。     

基于编辑距离的网页去重策略

互联网中存在着大量的重复网页,在进行信息检索或大规模网页采集时,网页去重是提高效率的关键之一。本文在研究＂指纹＂或特征码等网页去重算法的基础上,提出了一种基于编辑距离的网页去重算法,通过计算网页指纹序列的编辑距离得到网页之间的相似度。它克服了＂指纹＂或特征码这类算法没有兼顾网页正文结构的缺点,同时从网页内容和正文结构上进行比较,使得网页重复的判断更加准确。实验证明,该算法是有效的,去重的准确率和召回率都比较高。
