摘要： Embodiments of the invention relate to message queuing. In one embodiment, a request from an application for retrieving a message from a queue is received. The queue is stored across multiple nodes of a distributed storage system. A preference with respect to message order and message duplication associated with the queue is identified. A message sequence index associated with the queue is sampled based on the preference that has been identified. The message is selected in response to the sampling. The message that has been selected is made unavailable to other applications for a given interval of time, while maintaining the message in the queue. The message is sent to the application.
摘要翻译：本发明的实施例涉及消息队列。在一个实施例中，接收来自应用程序的来自队列检索消息的请求。队列存储在分布式存储系统的多个节点上。识别与队列相关联的消息顺序和消息复制的偏好。基于已经识别的偏好，对与队列相关联的消息序列索引进行采样。选择该消息以响应采样。已经选择的消息在给定的时间间隔内对其他应用程序不可用，同时将消息保留在队列中。该消息被发送到应用程序。

摘要： A semantic publish/subscribe system enables semantic event routing and allows publishers (resp. subscribers) to use self-defined event schemas to publish (resp. subscribe) events. The constraints on value-based publish/subscribe systems that publishers and subscribers must share the same event schemas are removed. With ontology support, the system conducts event correlation based on their semantics using relational operators. Event sources are searched for subscriptions and selected events are automatically correlated according to subscriptions. The system enables efficient semantic event routing by rewriting the subscription SQL statement, wherein no redundant events are generated.
摘要翻译：语义发布/订阅系统启用语义事件路由，并允许发布者（分别订阅者）使用自定义事件模式来发布（或者预订）事件。发布商和订阅者必须共享相同事件模式的基于价值的发布/订阅系统的限制将被删除。通过本体支持，系统使用关系运算符根据其语义进行事件关联。搜索订阅的事件源，并根据订阅自动关联选定的事件。该系统通过重写订阅SQL语句来实现有效的语义事件路由，其中不生成冗余事件。

摘要： A method, information processing system, and computer readable medium for modifying at least one data warehouse schema based on detected changes in an associated observation model are disclosed. The method includes determining if at least one new observation model has been created. The method also includes determining if at least one existing observation model is associated with the new observation model. In response to the existing observation model being associated with the new observation model, at least one changed attribute is identified by comparing the new observation model and the existing observation model. A set of files associated with the existing observation model is updated to reflect the changed attribute between the new observation model and the existing observation model.
摘要翻译：公开了一种基于相关观察模型中检测到的变化来修改至少一个数据仓库模式的方法，信息处理系统和计算机可读介质。该方法包括确定是否已经创建了至少一个新的观察模型。该方法还包括确定至少一个现有观察模型是否与新的观察模型相关联。响应于与新观测模型相关联的现有观测模型，通过比较新的观测模型和现有的观测模型来识别至少一个变化的属性。更新与现有观察模型相关联的一组文件，以反映新观测模型与现有观测模型之间变化的属性。

摘要： A system and method permits a user to observe the Quality of Service (QoS) of Web services and allows dynamic selection based on the user's preference. The system is built on QoS observation meta-model and comprises a QoS observation manager, service criteria generator, service repository, evaluation manager and service invocation manager. The QoS observation manager allows users to define observation model and deploy to the service criteria generator. The service criteria generator computes the QoS criteria values of services by subscribing events, which include user feedback events and service execution events, based on deployed observation model. The service repository provides the persistence storage for QoS criteria value. The evaluation manager allows users to specify selection preferences and select services based on QoS ranking. The service invocation manger invokes Web services and publishes events according to the QoS of Web services. The system enables users to observe the QoS of Web service and select Web service based on QoS ranking that reflects the user's selection preference.
摘要翻译：系统和方法允许用户观察Web服务的服务质量（QoS），并允许基于用户的偏好进行动态选择。该系统建立在QoS观察元模型上，包括QoS观察管理器，服务标准生成器，服务仓库，评估管理器和服务调用管理器。 QoS观察管理器允许用户定义观察模型并部署到服务标准生成器。服务标准生成器基于部署的观察模型，通过订阅事件（包括用户反馈事件和服务执行事件）来计算服务的QoS准则值。服务存储库为QoS标准值提供持久性存储。评估管理器允许用户根据QoS排名指定选择偏好和选择服务。服务调用管理器根据Web服务的QoS调用Web服务并发布事件。该系统使用户能够观察Web服务的QoS，并根据反映用户选择偏好的QoS排序选择Web服务。
