Understanding the interrelation between information diffusion in online social media and user web interests can help the web ecosystem stakeholders in developing new services and designing efficient systems with optimized resources. This paper explores whether or not one can infer the trends of topics in the web by observing the Twitter microcosm. Using data- sets collected from Twitter and two representative web services （Google and Alexa）, this work con- ducts a comparative analysis between trending patterns of topics in Twitter and in the web by consid- ering both the temporal and spatial perspectives, and finds that individual topics in Twitter and in the web share similar trending patterns both from the temporal and spatial aspects. Nevertheless, the tren- diness in Twitter can precede for a few hours and is highly unstable compared to the one in web. The application of these findings is also discussed on ad keywords planning in Search Engine Marketing.展开更多

In order to solve some of these problems, stakeholders need to observe and talk about the river. Also recently, the ＂MIZBERING Project＂ has been opening up possibilities for renewing riverside uses of lost activities from the old days in Japan. This project is being conducted by citizens, companies and government administrations with an interest in waterside areas. The First MIZBER1NG Zuibaiji River Conference was held to discuss the issues of the Zuibaiji Basin. Its purpose was to visit and search out the nature and history of the entire Zuibaiji Basin from its mountains to the sea and to rediscover the Zuibaiji Basin, and finally to discuss future plans for the Zuibaiji Basin and Imazu Tidal Flat at its outlet. After visiting the Zuibaiji Basin, we discovered a problem that the Zubaiji Dam is holding not only water but also sand, and this problem affects the environment of the Zuibaiji Basin, such as its ecosystem and topography. Finally, we provided a venue for the local people to discuss problems and future plans for the Zuibaiji Basin.展开更多
