    • Disclosed is a general framework for extracting semantics from composite media content at various resolutions. Specifically, given a media stream, which may consist of various types of media modalities including audio, visual, text and graphics information, the disclosed framework describes how various types of semantics could be extracted at different levels by exploiting and integrating different media features. The output of this framework is a series of tagged (or annotated) media segments at different scales. Specifically, at the lowest resolution, the media segments are characterized in a more general and broader sense, thus they are identified at a larger scale; while at the highest resolution, the media content is more specifically analyzed, inspected and identified, which thus results in small-scaled media segments.
    • 公开了从复合媒体内容以各种分辨率提取语义的一般框架。 具体地,给定媒体流,其可以由包括音频,视觉,文本和图形信息的各种类型的媒体模式组成,所公开的框架描述了如何通过利用和集成不同媒体特征来在不同级别提取各种类型的语义。 该框架的输出是不同尺度的一系列带标签(或注释)的媒体片段。 具体来说,在最低分辨率下,媒体部分的特征更广泛和更广泛,因此它们被更广泛地识别出来。 而在最高分辨率下,更具体地分析,检查和识别媒体内容,从而导致小规模媒体片段。

    • A mechanism for controlling live migration of a running application between a source machine and a target machine. At least one application characteristic and at least one network characteristic are obtained. An objective function that defines a cost to migrate from the source machine to the target machine as a function such as a weighted combination of at least one cost property is obtained. The objective function is optimized using the at least one application characteristic and the at least one network characteristic to determine a policy specifying when to switch execution of the running application from the source machine to the target machine. Live migration of the application from the source machine is controlled to send pages from the source machine to the target machine in accordance with the policy, and to switch the execution of the application from the source machine to the target machine at a state specified by the policy.

    • Computer implemented method, system and computer usable program code for achieving transactional quality of service in a transactional object store system. A transaction is received from a client and is executed, wherein the transaction comprises reading a read-only derived object, or reading or writing another object, and ends with a decision to request committing the transaction or a decision to request aborting the transaction. Responsive to a decision to request committing the transaction, wherein the transaction comprises writing a publishing object, events are delivered to event stream processing queries, and are executed in parallel with executing of the transaction. Responsive to a decision to request committing a transaction that comprises reading a read-only derived object, a validation is performed to determine whether the transaction can proceed to be committed, whether the transaction should abort, or whether the validation should delay waiting for one or more event stream processing queries to complete.

    • System and method for partitioning a video into a series of semantic units where each semantic unit relates to a generally complete thematic topic. A computer implemented method for partitioning a video into a series of semantic units wherein each semantic unit relates to a theme or a topic, comprises dividing a video into a plurality of homogeneous segments, analyzing audio and visual content of the video, extracting a plurality of keywords from the speech content of each of the plurality of homogeneous segments of the video, and detecting and merging a plurality of groups of semantically related and temporally adjacent homogeneous segments into a series of semantic units in accordance with the results of both the audio and visual analysis and the keyword extraction. The present invention can be applied to generate important table-of-contents as well as index tables for videos to facilitate efficient video topic searching and browsing.
