ADSL免代理共享上网的两种方案

近几年来,随着科技的发展,许多网络通讯公司、电脑公司诞生,市场竞争导致了电脑价格、宽带上网的价格迅速下降,许多学生与家庭已经拥有电脑,校园里的学生宿舍与家庭组网已经是屡见不鲜;学生宿舍或家庭用户大多都是组建局域网通过ADSL调制解调器拨号共享宽带上网,目前ADSL免代理共享上网主要有两种方式,现介绍这两种ADSL免代理共享上网方案。     

基于非参数秩和检验的B站电影评分系统研究

该文通过爬虫代码搜集了当前B站电影栏目列表中的所有电影(约1000部),同时爬取每部电影下的所有评分数据(约65万条),每条评分数据包含评分时间与用户的ID信息。通过非参数统计中的Mann-Whitney秩和检验对搜集的数据进行分析和研究,结果表明:B站电影栏目中第一次评分人员的比例会对评分产生显著影响。同时参考美国IMDb贝叶斯加权统计算法中只收录“老用户”评分的处理方式,对B站评分系统提出建议,使评分能更加客观、全面地为观众提供参考。

Updating broken web links: An automatic recommendation system

Broken hypertext links are a frequent problem in the Web. Sometimes the page which a link points to has disappeared forever, but in many other cases the page has simply been moved to another location in the same web site or to another one. In some cases the page besides being moved, is updated, becoming a bit different to the original one but rather similar. In all these cases it can be very useful to have a tool that provides us with pages highly related to the broken link, since we could select the most appropriate one. The relationship between the broken link and its possible linkable pages, can be defined as a function of many factors. In this work we have employed several resources both in the context of the link and in the Web to look for pages related to a broken link. From the resources in the context of a link, we have analyzed several sources of information such as the anchor text, the text surrounding the anchor, the URL and the page containing the link. We have also extracted information about a link from the Web infrastructure such as search engines, Internet archives and social tagging systems. We have combined all of these resources to design a system that recommends pages that can be used to recover the broken link. A novel methodology is presented to evaluate the system without resorting to user judgments, thus increasing the objectivity of the results, and helping to adjust the parameters of the algorithm. We have also compiled a web page collection with true broken links, which has been used to test the full system by humans.
