The transnational marriage is a phenomenon with ever-increasing in Taiwan and around the world. For a student who has a transnational foreign mother, home-school communication is often an obstacle because the foreign mother has language difficulty understanding the delivered messages in the communication book from teachers. In order to improve parent-teacher communications for the transnational families, we designed and constructed the cloud service platform with online multilingual communications and translation service functions, such that teachers can prepare different sheets of multilingual messages for home-school communication books and foreign mothers can read the messages from the teachers in their native languages through the web interface.展开更多

The platform can facilitate expense reduction and improve the scalability of the cloud, which is divided into three layers： The user-layer receives requests from end-users, the auction-layer matches the requests with the cloud services provided by the Cloud Service Provider（CSP）, and the CSP-layer forms a coalition to improve serving ability to satisfy complex requirements of users.In fact, the aim of the coalition formation is to find suitable partners for a particular CSP. However, identifying a suitable combination of partners to form the coalition is an NP-hard problem. Hence, we propose approximation algorithms for the coalition formation. The Breadth Traversal Algorithm（BTA） and Revised Ant Colony Algorithm（RACA） are proposed to form a coalition when bidding for a single cloud service in the auction. The experimental results show that RACA outperforms the BTA in bid price. Other experiments were conducted to evaluate the impact of the communication cost on coalition formation and to assess the impact of iteration times for the optimal bidding price. In addition, the performance of the market model was compared to the existing CA-based model in terms of economic efficiency.展开更多
