    • A push-based filtering of objects in a client-server hierarchy based on usage information. A method of annotating a push object with meta information on its content and/or urgency is also described. Objects can be staged at the server(s) to provide fast access when the filtered object is later requested. The PICS protocol may be used to communicate various types of information: e.g., by the content provider or a higher level proxy to annotate the object, including an urgency, a summary or title, a group classification, and/or an identity of the push; to convey usage or preference information on pushed objects up the hierarchy, including usage information and user preferences based on object group classifications; and to convey a staging status of each staged object down the hierarchy to improve caching efficiency. An object may include a content hierarchy such as a title, a summary and the full content. The filtering process can factor in not only which next (lower) level nodes will receive the push, but also the content level each node will receive. The push filtering decision can be based on aggregate usage information at the lower level proxy or client nodes. A staging decision can be based on the filtering decision, the successful completion of the push to the selected lower level proxies/clients, object usage information and/or a staging decision on other nodes in the hierarchy. An efficient means to purge a staged object is also described.
    • 基于使用信息的客户机 - 服务器层次结构中的对象的基于推送的过滤。 还描述了使用具有关于其内容和/或紧急性的元信息来注释推送对象的方法。 当稍后请求过滤的对象时,可以在服务器上上传对象以提供快速访问。 PICS协议可以用于传达各种类型的信息:例如,由内容提供商或更高级别的代理来标注对象,包括紧急性,摘要或标题,群组分类和/或推送的身份 ; 基于对象组分类来传送层次结构上的推送对象的使用或偏好信息,包括使用信息和用户偏好; 并将层次结构中的每个阶段对象的分期状态传达给提高缓存效率。 对象可以包括诸如标题,摘要和完整内容的内容层次结构。 过滤过程不仅可以考虑下一个(较低)级节点将接收推送,还可以考虑每个节点将接收的内容级别。 推送过滤决定可以基于较低层代理或客户端节点上的聚合使用信息。 分期决策可以基于过滤决策,成功完成对所选择的较低级别代理/客户端的推送,对象使用信息和/或对该层级中的其他节点的分级决定。 还描述了清除分段对象的有效方法。

    • A method and apparatus to dynamically maintain META-tag information specifying categorization and/or degree of compound documents, which are collections or hierarchy of collections of objects (possibly web pages), for efficient retrieval of leaf or intermediate objects with specific characteristics without the need to search any content of the collection. The specific characteristic and the contents of the collection can change constantly both qualitatively and quantitatively (including the insertion, deletion and update of objects). While dynamically maintaining the META-tag information, there are no inclusion restrictions on these compound documents, i.e., any collection can contain itself either directly or recursively; and all objects within a META-tagged compound document are not required to participate. The PICS protocol may be used to specify this META-tag information with both categorization and degree; to reflect the obsolescence, currency or freshness of an objects; to validate a given object using a digital signature; and to enable charging for the META-tag service. Aggregation methods are provided to enable maximization, minimization, and averaging; to limit the propagation of META-tags; and to handle the time-out of META-tag and information validity.
    • 一种用于动态地维护META标签信息的方法和装置,所述META标签信息指定复合文档的分类和/或程度,所述复合文档是对象(可能的网页)的集合或层次结构,用于有效地检索具有特定特征的叶或中间对象而不需要 搜索集合的任何内容。 集合的具体特征和内容可以在定性和定量上(包括对象的插入,删除和更新)不断变化。 在动态维护META标签信息的同时,对这些复合文档没有包含限制,即任何集合都可以直接或递归地包含它们; 并且META标记的复合文档中的所有对象都不需要参与。 PICS协议可用于指定具有分类和度数的META标签信息; 反映物体的过时,货币或新鲜度; 使用数字签名验证给定对象; 并为META标签服务启用计费。 提供聚合方法以实现最大化,最小化和平均化; 限制META标签的传播; 并处理META标签的超时和信息有效性。

    • The present invention relates to a method for creating a meta-document. The method collects at least one hyperlinked document based on a seed document and cross-references the documents within the collection. Cross-referencing includes resolving an anchor and an object, and indexing the resolved anchor and object based on respective locations within a meta-document. The method organizes the collected documents and seed documents. The method also publishes the meta-document including the cross-referenced documents. Preferably, the method of collecting includes accepting the seed document having an anchor pointing to an object, and adding a document containing the object to the collection. In addition, collecting includes the step of manually modifying the collection. The meta-document is a collection of the seed document and the hyperlinked document. Further, the index is one of a footnote, an end note, a table of contents, and an appendix.
    • 本发明涉及一种创建元文档的方法。 该方法基于种子文档收集至少一个超链接的文档,并交叉引用集合中的文档。 交叉引用包括解析锚和对象,并且基于元文档内的相应位置对解析的锚和对象进行索引。 该方法组织收集的文件和种子文件。 该方法还会发布包含交叉引用文档的元文档。 优选地,收集方法包括接受具有指向对象的锚点的种子文档,以及将包含对象的文档添加到集合。 此外,收集包括手动修改集合的步骤。 元文档是种子文档和超链接文档的集合。 此外,该指数是脚注,终端笔记,目录和附录之一。
