The application discloses a data integration method and device. Among them, the method includes: obtaining multiple original data sources, the original data sources include image data sources and text data sources; performing redundant processing on multiple original data sources to obtain processed data sources; respectively constructing The local ontology corresponding to each original data source obtains multiple local ontologies, and the local ontology contains data description information of the corresponding original data source; constructs a global ontology based on multiple local ontologies, and the global ontology contains data descriptions of multiple original data sources information. This application solves the technical problem of using ontology-based data integration methods for data integration at the present stage, which requires a lot of manpower and material resources when building ontology, and requires the participation of experts in related fields when building a specific domain ontology, resulting in high cost.
Description
technical field [0001] The present application relates to the field of data integration, in particular, to a data integration method and device. Background technique [0002] In the early stage of informatization construction, due to the lack of effective and reasonable planning and collaboration, the phenomenon of "information islands" is common, a large amount of redundant data and garbage data exist in the information system, the data quality cannot be guaranteed, and the utilization efficiency of information is obvious. Low, in order to solve this problem, data integration technology came into being. Data integration technology is to coordinate the mismatch between data sources, integrate heterogeneous, distributed, and autonomous data, and provide users with a single view so that they can access data sources transparently. [0003] When we realize data integration, we need to solve the following problems: First, heterogeneity, data heterogeneity includes two aspects: f...
