Semantic Web Technology Using Collective Intelligence of Mobile Social Networks

In the past several years, the World Wide Web has experienced a new era, in which user communities are greatly involved and digital content explodes via the Internet. Community information systems have been highlighted with the emerging term mobile Social Network. In this paper, we explore the impact of mobile social software on the community of cultural heritage management. Furthermore, mobile and ubiquitous technologies have provided capabilities for more sophisticated approach to cultural heritage management. We analyze these features of mobile information systems for cultural communities. We also present a mobile community framework with mobile Web Services to enable professionals to collect, manage and retrieve cultural heritage information in wide user communities. Recently, there has been an increasing interest in a social network. In a social network, nodes and links represent participants and their friendships, respectively. We have designed and implemented a query propagation mechanism and its applications to realize a social network composed by cellular phone users. In these applications, users can retrieve information from their friends or their friends' friends by propagating the query in the network. To propagate a query in a wide range and improve the query success ratio, most users who receive the query must relay it to all their friends. However, this increases communication packets. In this paper, we propose a query routing method to decrease the number of communication packets by using user profiles.
