摘要： Techniques are provided maintaining data that indicates for a plurality of query terms whether the plurality of query terms are date-qualified query terms. A query is received, and in response to receiving the query, the query is inspected to determine that the query contains a particular date-qualified query term. Then it is determined that the particular date-qualified query term has been associated with a plurality of dates, and it is determined which of the plurality of dates with which to associate the date-qualified query term for the query, based at least in part on the frequency with which each particular date of the plurality of dates has been associated with the particular date-qualified query term.

摘要： Techniques are provided for (1) extending SQL to support direct invocation of frequent itemset operations, (2) improving the performance of frequent itemset operations by clustering itemset combinations to more efficiently use previously produced results, and (3) making on-the-fly selection of the occurrence counting technique to use during each phase of a multiple phase frequent itemset operation. When directly invoked in an SQL statement, a frequent itemset operation may receive input from results of operations specified in the SQL statement, and provide its results directly to other operations specified in the SQL statement. By clustering itemset combinations, resources may be used more efficiently by retaining intermediate information as long as it is useful, and then discarding it to free up volatile memory. Dynamically selecting an occurrence counting technique allows a single frequent itemset operation to change the occurrence counting technique that it is using midstream, based on cost considerations and/or environmental conditions.
摘要翻译：提供技术用于（1）扩展SQL以支持频繁项目集操作的直接调用，（2）通过聚类项目组合来提高频繁项目集操作的性能，以更有效地使用先前生成的结果，以及（3）选择在多相频繁项目集操作的每个阶段期间使用的发生计数技术。当在SQL语句中直接调用时，频繁的项目集操作可以从SQL语句中指定的操作结果接收输入，并将其结果直接提供给SQL语句中指定的其他操作。通过对项目集合进行聚类，可以通过保留中间信息来更有效地使用资源，只要它是有用的，然后丢弃它来释放易失性存储器。动态选择发生计数技术允许单个频繁项目集操作基于成本考虑和/或环境条件来改变它正在中游使用的发生计数技术。

摘要： A method and apparatus for discovering polysemous words and classifying polysemous words found in web documents. All document corpi in any natural language have words that have multiple usage contexts or words that have multiple meanings. Semantic analysis is not feasible for classifying all word occurrences in all documents on the web, which contain trillions of words in total. In addition, semantic analysis typically cannot distinguish multiple usages of a given meaning of a given word. In one embodiment of this invention, polysemous words in natural languages can be discovered by analyzing the co-occurrence of other words with the polysemous word in web documents. In one embodiment, the multiple meanings and usages of a polysemous word can be determined by analyzing the co-occurrences of other words with the polysemous word. No semantic analysis is used in discovering or classifying polysemous words.

摘要： Join predicate push down transformations push down a join predicate of an outer query into a view. Among the types of views for which join predicate push down is performed are a view with a GROUP BY or DISTINCT operator, an anti-joined or semi-joined view, and a view that contains one or more nested views. During optimization, join predicate push down may be used to generate many transformed queries for comparison. The number of query transformations performed for comparison is managed.

摘要： A method for IP Security within Multi-Topology Routing is disclosed. Disclosed methods may also include IKE extensions. A route eligible for IPSec protection is injected into a topology routing table. Network traffic can then be protected in accordance with a security session, such as an IPSec session, between a first network node and a second network node and forwarded through a selected topology to take advantage of the service-differentiation capabilities of MTR.

摘要： A project management system manages project schedule data using separate current and historical task schedule data structures. In general, current schedule data is stored separately from historical schedule data, so that the current schedule data may be retrieved separately from the historical task schedule data. The project management system may also maintain unscheduled tasks as “to-do lists.” Tasks may be added to a member's schedule without specifying any planned dates and the tasks are added to the database. The tasks have an associated revision number of 0 to indicate that the tasks were added, but not yet scheduled. The tasks are displayed in the member schedule editor and in Web page schedules. The tasks may then be displayed in the member schedule editor and in Web page schedules in a manner that allows a user to readily determine that the tasks are “to-do list” tasks.
摘要翻译：项目管理系统使用单独的当前和历史任务计划数据结构来管理项目进度数据。通常，当前日程数据与历史计划数据分开存储，从而可以与历史任务调度数据分离地检索当前日程数据。项目管理系统还可以将非计划任务作为“待办事项列表”进行维护。可以将任务添加到成员的计划中，而不指定任何计划日期，并将任务添加到数据库。这些任务的修订版本号为0，表示已添加但尚未安排任务。任务显示在成员计划编辑器和网页计划中。然后，任务可以以允许用户容易地确定任务是“待办事项列表”任务的方式显示在成员计划编辑器和网页调度中。

摘要： Mechanisms model, detect, and predict user behavior as a user navigates the Web. In one embodiment, mechanisms model user behavior using predictive models, such as discrete Markov processes, where the user's behavior transitions between a finite number of states. The user's behavior state may not be directly observable (e.g., a user does not proactively indicate what behavior state he is in). Thus, the behavior state of a user is usually only indirectly observable. Mechanisms use predictive models, such as hidden Markov models, to predict the transitions in the user's behavior states.
摘要翻译：机制在用户导航Web时模拟，检测和预测用户行为。在一个实施例中，机制使用诸如离散马尔可夫过程之类的预测模型来模拟用户行为，其中用户的行为在有限数量的状态之间转换。用户的行为状态可能不是可以直接观察到的（例如，用户不主动地指示他所处的行为状态）。因此，用户的行为状态通常只是间接可观察的。机制使用预测模型，如隐马尔可夫模型，来预测用户行为状态的转变。

摘要： A method and apparatus is disclosed for graceful restart in a multi-process operating system. A transport protocol process, which is capable of restarting independently from the operating system, is executed in a network element. The network element executes a Border Gateway Protocol (BGP) process, which installs one or more routes in a global Routing Information Base (RIB). When the BGP process detects that the transport protocol process has become unavailable, the BGP process keeps the one or more routes in the global RIB even though the transport protocol process is not available.

摘要： A declarative mechanism is used to manage large documents within a repository. The large documents are sectioned into subdocuments that are linked together by a parent document. The combination of the parent document and subdocument is referred to as a compound document. There are multiple options for configuring rules to break up a source document into a compound document and naming the subdocuments. The compound documents may be queried using statements that treat the compound document as a single XML document, or the parent document of a subdocument may be queried and treated independently. Access control and versioning can be applied at the finer granularity of the subdocument.
摘要翻译：声明机制用于管理存储库中的大型文档。大文档被分段到由父文档链接在一起的子文档中。父文档和子文档的组合被称为复合文档。有多种选项用于配置将源文档分解为复合文档并命名子文档的规则。可以使用将复合文档视为单个XML文档的语句来查询复合文档，或者可以单独查询和处理子文档的父文档。访问控制和版本控制可以在子文档的更细粒度上应用。
