Abstract(in English)	In this paper, we suggest a comparison engine and schema generator for semistructured data. Our comparison engine discovers differences between semistructured data. The schema generator makes common schema of OEM graphs from semistructured data, semistructure data can be comparable. We assume that data with the same or similar property belong to the same category, we call these data "same field data". Difference between same-field data can be discovered from their OEM graphs by using its common schema. We use upper schema for discovering the difference on attribute values, lower schema for discovering that on structure. Moreover, visualization of difference are represented by the colored OEM graphs.
