For performance analysis of integrated social-sensor networking service, a unified approach in a unified web service was studied. As a convenient and usable mobile web service for unified social-sensor networking service, the multilingual singlecharacter domain names as indexing keys to metadata information in ubiquitous web service are convenient mobile interfaces when searching for social-sensor information and registering metadata information. We introduce the sketched design goals and experience of mobile interaction in Korea, Japan and China, with the implementation of integrated social-sensor networking service as an example of unified web service.
