In distributed e-commerce environment, there?s a need to integrate information of services from different information sources in order to discover services. There are structure and semantic differences between services information stored in information 1sources. Traditional ontology pattern-matching can solve some structure difference problem. But in order to solve semantic difference problem, we propose a architecture for context-based information integration. Within the domain of numerical information integration, we define some novel modeling primitives of translation ontology and propose an algorithm for translation. At last, we give an example of currency translation, and we show how to integrate numerical information using the methodology we proposed.
