摘要： A method and apparatus that detects mirrored host pairs using information about a large set of pages, including URLs. The identities of the detected mirrored hosts are then saved so that browsers, crawlers, proxy servers, or the like can correctly identify mirrored web sites. The described embodiments of the present invention look at the URLs of pages hosts to determine whether the hosts are potentially mirrored.

摘要： A method and system that detects mirrored host pairs using information about a large set of pages, including one or more of: URLs, IP addresses, and connectivity information. The identities of the detected mirrored hosts are then saved so that browsers, crawlers, proxy servers, or the like can correctly identify mirrored web sites. The described embodiments of the present invention use one or a combination of techniques to identify mirrors. A first group of techniques involves determining mirrors based on URLs and information about connectivity (i.e., hyperlinks) between pages. A second group of techniques looks at connectivity information at a higher granularity, considering all links from all pages on a host as one group and ignoring the target of each link beyond the host level.
摘要翻译：使用关于大量页面的信息来检测镜像主机对的方法和系统，包括以下一个或多个：URL，IP地址和连接信息。然后保存检测到的镜像主机的身份，以便浏览器，爬网程序，代理服务器等可以正确识别镜像的网站。所描述的本发明的实施例使用一种或技术的组合来识别反射镜。第一组技术涉及基于URL和关于页面之间的连接性（即，超链接）的信息来确定镜像。第二组技术以更高的粒度来考虑连接信息，考虑到主机上所有页面的所有链接为一个组，并忽略超出主机级别的每个链接的目标。

摘要： A computer-implemented method and system providing both query-specific bookmarking and query-specific data collection. These features allow users to search more efficiently on the WWW by allowing users to explicitly maintain their search context. In addition, users can also collect query-specific relevance and usage data. User marked search results are saved as leads, which are displayed on a user interface such as a SearchPad. One embodiment of the invention involves extending HTML to include a Query attribute that saves the query context and returns it with a search result page. Another embodiment involves the use of cookies to save the query context. Saved query-specific bookmarks and query-specific data can be periodically saved to a central site, although not all embodiments perform this task.
摘要翻译：一种计算机实现的方法和系统，提供查询特定的书签和特定于查询的数据收集。这些功能允许用户通过允许用户明确维护其搜索上下文来更有效地搜索WWW。此外，用户还可以收集特定于查询的相关性和使用数据。用户标记的搜索结果保存为引线，显示在用户界面（如SearchPad）上。本发明的一个实施例涉及扩展HTML以包括保存查询上下文的Query属性并使用搜索结果页面返回它。另一个实施例涉及使用Cookie来保存查询上下文。保存的特定于查询的书签和特定于查询的数据可以定期保存到中央站点，尽管并非所有实施例都执行此任务。

摘要： The present invention relates to methods and systems for requesting and providing information in a social network. A method can comprise outputting an information request interface, which can provide a user with the ability to request information from at least one member of a social network associated with the user. One or more members of the social network can be notified of the user's information request and can provide, or assist in providing, the requested information to the user.

摘要： A method and apparatus perform vector error diffusion and result in reduced graininess of a color halftone image representing a continuous tone image. The method controls the output colors while reducing the visibility of the error diffusion pattern inherent in forming a bilevel image. Specifically, the method involves influencing the dot pattern correlation using vector error diffusion and takes into account the effects caused by the interactions of dot patters for all of the different color components.
摘要翻译：一种方法和装置执行向量误差扩散，并导致代表连续色调图像的彩色半色调图像的颗粒度降低。该方法控制输出颜色，同时降低形成二维图像中固有的误差扩散模式的可视性。具体地说，该方法包括使用向量误差扩散来影响点图案相关性，并且考虑由点图案对所有不同颜色分量的相互作用所引起的影响。
