Due to the masses of social activities information available on the Internet, a major challenge is how to access them efficiently. The traditional keyword search is imprecise and inconvenient for web surfing to find interest information on the internet. This study addresses this issue by defining a Multi-layered Cloud Service Framework (MCSF) for integrating ontology and Web 2.0 technologies into cloud computing environment. The proposed MCSF is used to develop an Intelligent Social Activity Cloud Platform (ISACP) that provides customized social activity for personal needs. To demonstrate the feasibility of ISACP, the experimental results illustrate the efficiency and effectiveness of the proposed approach.
