摘要：With the development of information technology today is the nature of today's information is also experiencing growth. These developments encourage a more dynamic source of information, autonomy, variety and large. Diversity occurs not only at the technical level but also at the level of representation of information. This difference can occur at syntactic, schematic and semantic level. This diversity also occurs in the hotel domains that do not have a standard that refers to the tourism domain. The existing traditional methods have not been able to overcome the problem of diversity to achieve interoperability in heterogeneous data sources. So with this method the obtained results are not necessarily relevant to the user wishes. One of the most viable approaches is the creation �Query Rewriting� based on ontology and mapping. As a mapping approach it is used GLAV (Global-Local-As-View) which is a combination of approaches GAV (Global-As-View) and LAV (Local-As-View). While the diversity of existing terminology in each source of data for specific domains basically state the same meaning as defined in the common ontology. In this paper it will be explained the illustrations of �Query Re-writing� and the steps to create mappings for the hotel domain using the Protege 3.4 as tool.
