    • Techniques are disclosed for automatic static summarization of videos. For example, a method of creating a static summary of a video comprises the following steps. Shots in the video are detected, wherein the detected shots are frames of the video having a correlation. The detected shots are clustered into clusters based on similarity. The clusters of shots are ranked. At least a portion of the shots are selected based on cluster ranking for inclusion in the static summary. The static summary is generated by combining thumbnail images of the selected shots. Prior to the ranking step, the method may further comprise detecting a presence of slides in any of the shots, and the ranking of a given shot is based in part on whether the shot is a slide. By way of example, such static summaries can be shared in emails and in calendar applications.
    • 公开了用于视频的自动静态摘要的技术。 例如,创建视频的静态摘要的方法包括以下步骤。 检测到视频中的拍摄,其中检测到的拍摄是具有相关性的视频的帧。 基于相似性将检测到的照片聚类成簇。 这些镜头的排列是排名。 至少一部分镜头是根据包含在静态摘要中的聚类排列来选择的。 通过组合所选镜头的缩略图来生成静态摘要。 在排序步骤之前,该方法还可以包括在任何拍摄中检测幻灯片的存在,并且给定镜头的排名部分地基于镜头是否是幻灯片。 作为示例,这些静态摘要可以在电子邮件和日历应用程序中共享。

    • Automated contextual information retrieval techniques are provided based on multi-tiered user modeling and a dynamic retrieval strategy. Content relevant to a current message is presented by initially obtaining a multi-tiered user model containing a multi-tiered representation of interactions of a first user with each contact, wherein the multi-tiered representation includes a plurality of topic models each corresponding to interactions between the first user and one contact. The topic models contain a set of topics, each containing topic keywords. Context information is extracted based on content of the current message, a sender and/or a recipient of the current message, and the multi-tiered user model. A retrieval strategy is determined based on the extracted context information. Contextual queries are generated to search the information repositories selected based on the determined retrieval strategy. Content relevant to the current message is presented based on search results from the selected information repositories.
    • 基于多层次用户建模和动态检索策略提供了自动上下文信息检索技术。 通过最初获得包含第一用户与每个联系人的交互的多层次表示的多层次用户模型来呈现与当前消息相关的内容,其中所述多层表示包括多个主题模型,每个主题模型对应于 第一个用户和一个联系人。 主题模型包含一组主题,每个主题包含主题关键字。 基于当前消息的内容,当前消息的发送者和/或接收者以及多层次用户模型来提取上下文信息。 基于提取的上下文信息确定检索策略。 生成上下文查询以搜索基于确定的检索策略选择的信息库。 基于所选信息存储库的搜索结果显示与当前消息相关的内容。

    • Methods and apparatus are provided for run-time user control of system-generated content. A user is presented with the system-generated content and can configure one or more rules at run-time. The rules identify one or more automated actions to perform upon the system-generated content when one or more conditions are satisfied. The automated actions are executed upon the system-generated content when the one or more conditions are satisfied. The exemplary automated actions may comprise transform, retrieve, update and alert. The conditions can specify, for example, when to perform the automated actions. Active tags may optionally be attached to or embedded directly in the system-generated content or in a document containing the system-generated content. Tools are optionally provided to allow a user to manage active tags.
    • 提供了用于系统生成内容的运行时用户控制的方法和装置。 向用户呈现系统生成的内容,并可以在运行时配置一个或多个规则。 当满足一个或多个条件时,规则识别在系统生成的内容上执行的一个或多个自动化动作。 当满足一个或多个条件时,自动化操作在系统生成的内容上执行。 示例性的自动化动作可以包括变换,检索,更新和警报。 条件可以指定例如何时执行自动化操作。 活动标签可以可选地附加到或直接嵌入系统生成的内容或包含系统生成的内容的文档中。 可选地提供工具以允许用户管理活动标签。
