Problems solved by technology

[0004] Aiming at the deficiencies and defects of the prior art, the present invention provides a multi-source data fusion system based on rules and credibility, so that it can provide a flexible and universal plug-and-play system for different information integration systems in a distributed environment. The data fusion system used in the current information integration system needs to repeatedly develop the data fusion function, and the existing data fusion system cannot meet the needs of the information integration system, as well as the problems of inflexibility and poor scalability, and promote the application and development of data fusion

Embodiment Construction

[0023] An embodiment of the present invention is described in detail below: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and processes are provided, but the protection scope of the present invention is not limited to the following embodiments.

[0024] The system of this embodiment uses a microcomputer as a device platform, and can perform data fusion on heterogeneous data source data in different information integration systems based on a series of fusion rules and data source credibility, and supports safe and reliable data transmission.

[0025]As shown in FIG. 1 , the system structure of this embodiment is logically divided into three layers, namely a system interaction layer, a data fusion layer and an application layer. The system interaction layer mainly includes the system interaction management server. The system connection unit of the system interaction management server is respo...

Abstract

The system includes system interaction management server (MS), certainty MS, data syncretizing MS, rule MS, display terminal. Connecting information integration system, the system interaction MS sands data to be interfused and relevant information to data syncretizing MS. data syncretizing MS syncretizes the inputted data through inference, and provides result for users through display terminal. In batch mode, user determines or further processes syncretized result. System returns final syncretized result back to external information integration system. Based on final syncretized result of system and QoS of each data sources in this syncretizing procedure, certainty MS modifies certainty of data sources. User can manage rule base in rule manager and certainty of each data source in data source certainty manager. Features are: legible modules, dynamic performance, generality and flexibility.

Description

technical field [0001] The invention relates to a system in the technical field of telecommunications, in particular to a rule-based and credibility-based multi-source data fusion system for solving data conflicts when multi-source heterogeneous data are integrated. Background technique [0002] The work of providing unified representation, storage, query and management of heterogeneous multiple data sources is called information integration. Since the data provided by different data sources for the same data item may conflict, information integration needs to use data fusion technology to fuse these conflicting data and eliminate data conflicts. At present, the information integration systems developed by different people and different organizations all need repeated development of data fusion function modules, the system flexibility is poor, and the cost of system development and maintenance is increased. At present, there is a lack of a flexible and scalable data fusion ...
