移动相册的复杂网络分析


  摘 要:带有照相功能的移动终端的普及,产生了大量的照片,记录了用户的日常生活,这些照片附带了大量的多维元数据如时间、地点、作者、事件等,如何利用多维的元数据有效管理这些照片是一个研究热点。创新地提出利用复杂网络的方法分析和可视化移动相册,将照片看做一个节点,利用照片的多维元数据之间的相关性建立照片之间的边,这样所有在相册中的照片就组成了一个多维复杂加权网络。分析了照片复杂加权网络的统计特性,揭示了其小世界特性。利用照片复杂网络,不仅可以可视化照片之间的多维关系,而且可以快速检索相关照片。

  Abstract:With the popularity of mobile terminal equipped with camera, lots of photos were taken to record the user daily life. The photos were associated with rich metadata such as time, location, author and event, etc. How to use these metadata to efficiently manage the photos has become a hot research topic.This paper proposed a novel method of complex graph to analyze and visualize mobile photo album.Considered a photo was as a node,used the relevance of photos based on multi-dimensional metadata to build the edges between nodes. So all photos in the album would be formed a complex multiple dimension weight network.This paper also analyzed the statistic feature of such a photo generated complex network, and discovered it had the small work effect. Photo complex network was used not only for visualization of multidimensional relation of photo, but also for quick photo retrieval.
