Hence, portlet description and discovery are the key issues that have to be considered for the development of portal-based composite applications. This paper proposes a novel concept POI （Presentation Oriented Interface） to describe the presentation features of a portlet, so that interactive web services may be extended to facilitate the selection and interoperation of portlets. Portlet discovery can be effectively achieved based on the calculation of POI similarity that considers both type and structure similarity. Experiments show that the proposed approach can improve the satisfaction of portlet discovery, and also facilitate the portlet interoperation, thereby achieving better application integration at presentation level.展开更多
