Abstract: A named entity integration model (NEIM) was proposed for Dataspace, as well as integration methods for named entities of heterogeneous data sources. Named entity integration model describes the relations among data source, named entity and the descriptions of entity. It supports any inquires from one of them to the other relevant information. I}he framework of named entity integration points out that the main works of the integration arc named entity and its information recognition, entity integration and mapping, and entity resolution. The integrated algorithm repre-Bents the integration methods of named entity and its information in heterogeneous data sources. Especially, for the structural and semi structured data, it constructs mapping rules, makes the system can continuous integration. The experiment validates the mapping rules.
