When developing hotel information platform, the service providers face an important issue, how to attract more hotels to join in their platform without significantly increasing integration cost but maintaining effective information integration? This paper considers the issue in two aspects of business integration policy and technology support, which bring up a novel Hotel Power Policy Approach for service providers to define different hotel partners and integrate heterogeneous hotel information. With this approach, a Hotel Information Collaboration Platform is proposed to implement the hotel power policy for integrating the complex real-world hotel information. ©2007 IEEE.
