This paper presents a method to model network delay for overlay network application. The network topology measurement technology and network AS information is used to build up model of network delay via AS and geographic distance. Based on global Internet measurement result, we calculated the parameters of the model. Furthermore, the model verification is done by comparing on AS-MMI protocol an...

In this research, we examine the relationship between power and three characteristics of construal—abstraction, valence, and certainty—in individuals’ verbatim reactions to the events of September 11, 2001 and during the immediate aftermath of the terrorist attacks. We conceptualize power as a form of social distance and find that position power (but not expert power) was positively associated ...

Markets that are well-integrated spatially are important to the stability and success of the economy because they balance supply and demand and create incentives for innovation. Electronic commerce has the potential to improve market integration by providing visibility into supply/demand conditions in different geographic regions and facilitating trade across geographic distance. We study the e...

A tremendous amount of information is being shared every day on social media sites such as Facebook, Twitter or Google+. However, only a small portion of users provide their location information, which can be helpful in targeted advertising and many other services. Current methods in location estimation using social relationships consider social friendship as a simple binary relationship. Howev...

The collection of speech data suitable for speech technology development is a challenge for under-resourced languages. Factors such as cost, availability of mother-tongue speakers and vast geographic distances call for techniques to optimise the data collection process in order to reduce re-collection of data. The use of mobile devices facilitate remote speech data collection. Although mobile (...

While the geographical domain has long been involved as an important part of the Linked Data, the small amount of Chinese linked geographical data impedes the integration and sharing of both Chinese and cross-lingual knowledge. In this paper, we contribute to the development of a new Chinese linked geographical dataset named Clinga, by obtaining data from the largest Chinese wiki encyclopedia. ...

The rapid emerging of mobile Internet provides new opportunities for information services. One of the service types is tied to mobile location technology that allows defining the geographical location of a mobile user. It enables the development of new class geographical information services. Location-based applications require careful development of the general architecture as well as a data f...

traditional leveraging statistical methods for analyzing today’s large volumes of spatial data have high computational burdens. to eliminate the deficiency, relatively modern data mining techniques have been recently applied in different spatial analysis tasks with the purpose of autonomous knowledge extraction from high-volume spatial data. fortunately, geospatial data is considered a proper s...

This paper proposes using data broadcasting to build urban intelligent information infrastructures. It presents a conceptual framework for integrating cellular network location management into geographical data broadcast to provide efficient location dependent services. Within the context of the proposed framework, the paper then discusses the four major research issues: generic and geographic ...
