Abstract

The invention relates to a fine grain scientific data fusion system based on minimal dependence. According to the system, mainly by utilizing the minimal dependence of data, a manner of active registration is adopted for strengthening the participant activity of a data source owner, reducing the technical difficulty of a data source participant and solving the data fusion problems of certain small and incomplete data sources. The system is of a distributed structure, so that the system has good expandability; and a flexible mechanism is provided by taking the minimal dependence, essential data pattern and the data logical layer of the fusion system of an essential data list as a data source mapping relation. The system interactive management server of a system application layer and a data publishing server respectively provide visual methods for data management, registration and access for different users. An information fusion server stored with the system uninterruptedly runs, so that the timeliness of data is ensured; and simultaneously, the fusion intelligence and the accuracy of system data are also greatly improved by the flexible application of fusion rules.

Description

technical field [0001] The present invention relates to a system in the field of information technology, specifically a fine-grained scientific research data fusion system based on minimum dependence, which is used for purposefully collecting scientific research data on the Internet. Background technique [0002] The information fusion system is a system that provides unified storage, query and management for multi-source heterogeneous data. Since data has different representations in different data sources, it is necessary to set specific data acquisition methods for each data source, and integrate these data to form practically meaningful data. [0003] Currently, the data source of data fusion is actively searched by the data fusion system, and a mapping relationship is established between the found data source schema and the target schema of the fusion system. This method is very passive, and it is easy to ignore some small, scattered, and not widely known data sources,...
