Construction of Web Camera Searching Environment Using the Next Generation Web

近年来，作为下一代Web，语义网引起了世界各国研究人员的广泛关注，相关研究成果在国际语义网会议等国际会议上也得到了积极的报道。在日本，研究成果也可以在各种学术团体中找到，比如网络智能和互动协会。虽然语义网已经引起了众多研究者的关注，但从用户的角度来看，我们不得不说语义网还不为人所熟知，还只是一个正在进行中的研究课题，我们认为这是因为目前对语义网的研究缺乏对应用的关注，过于注重基础设施。在这样的研究背景下，本文第一年(2007年)实现了一个网络摄像机发布平台，包括一个用于标注网络摄像机的元数据模式、一种元数据的表示方法以及一个网络摄像机和元数据的发布工具。2008年，我们利用该平台搭建了一个网络摄像机搜索环境。然后在2009年，也就是研究的最后一年，我们通过进行广泛的实验来研究我们的网络摄像头搜索环境的性能，并评估了环境的精确度、召回率和F度量。

Recently, as the next generation of Web, the Semantic Web has attracted considerable attention of researchers around the world, and research results related to it have been being actively reported at various international conferences such as ISWC (International Semantic Web Conference). In Japan, research results could also be found in various academic societies like the Web Intelligence and Interaction society. Although it has attracted considerable attention of the researchers, from viewpoint of the users, we have to say the Semantic Web has not been well known and is still no more than a research subject in progress.We think that this is because the present research on Semantic Web pay little attention to the application; it pays too much attention to the infrastructure. Thus, in this research, we focus our attention on the application of Semantic Web, and in particular, we construct practically a Web Camera Searching Environment in which Web cameras can be intellectually retrieved over the Semantic Web.Given such a background of research, in the first year (year 2007), we implemented a platform for publishing Web cameras, including a schema of metadata for tagging Web cameras, a presentation method of metadata, and a publishing tool of Web Camera and Metadata. In 2008, using the platform, we constructed a Web Camera Searching Environment. Then in 2009, the last year of the research, we studied the performance of our Web Camera Searching Environment by conducting extensive experiments, and evaluating the precision, recall rate, and F-measure of the environment.
