Information-Centric Networking (ICN) has recently emerged as a result of the increased demand to access contents regard-less of their location in the network services. This new approach facilitates content distribu-tion as a service of the network with lower de-lay and higher security in comparison with the current IP network. Applying ICN in current IP infrastructure leads to major complexities. One approach to deploy ICN with less com-plexity is to integrate ICN with Software De-fined Networking (SDN). The SDN controller manages the content distribution, caching, and routing based on the users’ requests. In this paper, we extend these context by addressing the ICN topology management problem over the SDN network to achieve an improved user experience as well as network performance. In particular, a centralized controller is designed to construct and manage the ICN overlay. Ex-perimental results indicate that this adopted topology management strategy achieves high performance, in terms of low failure in interest satisfaction and reduced download time com-pared to a plain ICN.

目的 视频精彩片段提取是视频内容标注、基于内容的视频检索等领域的热点研究问题。视频精彩片段提取主要根据视频底层特征进行精彩片段的提取,忽略了用户兴趣对于提取结果的影响,导致提取结果可能与用户期望不相符。另一方面,基于用户兴趣的语义建模需要大量的标注视频训练样本才能获得较为鲁棒的语义分类器,而对于大量训练样本的标注费时费力。考虑到互联网中包含内容丰富且易于获取的图像,将互联网图像中的知识迁移到视频
