Abstract: There is lots of deep web in each field, if people retrieve all deep web in an area to obtain the required information, the workload is very huge. For the above reason, the data source selection technology is introduced. There are rich relationships among entities in the area of medicine, effectively integrate the entity association can promote the people’s health. In order to enhance the efficiency of information integration for entity association, proposing a data source selection method based on the characteristics of the associated entities. Firstly, construct a matrix summary of entity association based on weight and link information; Secondly, propose a correlation calculation method of data source based on the query intent. A number of experiments based on field data collection are conducted, the result show that our method's accuracy and recall are higher. So, it can provide a effective support to the entity integration in medical field.
