Embodiment Construction

[0033] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementations.

[0034] Spatial data fusion technology can integrate the superior information of multi-source heterogeneous spatial data, and integrate and generate a new set of spatial data with higher accuracy, richer information, better current and higher value. A large amount of data in the data contains spatial location information. Therefore, the present invention regards the data as spatial data, and applies the spatial data fusion technology to the data fusion field to improve the quality of the data.

[0035] The rule engine is a rule-based expert system that abstracts business specifications as "rules" and business operations as "engines", which can separate the two processes of business specification formulation and business operation execution, and ensure that ...

Abstract

The invention belongs to the technical field of data fusion, and discloses a rule engine-driven data fusion method, which comprises the following steps of: setting an expression specification of a fusion rule; setting implementation specifications of the fusion engine; formulating fusion rules of four stages of data preprocessing, data integration, homonymous entity matching and homonymous entityfusion and constructing fusion rule bases corresponding to the four stages; analyzing fusion rules in the four-stage fusion rule library, creating a corresponding fusion engine for each fusion rule, and constructing fusion engine libraries corresponding to the four stages; reading the multi-source heterogeneous data; and enabling a user to specify a fusion rule, create a data fusion task, and calla fusion engine to automatically complete a data fusion process. According to the invention, the problem that a data fusion method in the prior art is difficult to meet the dynamic demand of data issolved.

Description

Technical field [0001] The invention relates to the technical field of data fusion, in particular to a data fusion method driven by a rule engine. Background technique [0002] In the process of data fusion, there are problems such as complex fusion logic and dynamic changes in fusion requirements. Conventional data fusion methods have a fixed fusion process, and the data involved in fusion and the data fusion process are fixed and unchanging, and it is difficult to meet the dynamics of data. demand. Summary of the invention [0003] The embodiment of the present application solves the problem that the data fusion method in the prior art cannot meet the dynamic demand for data by providing a data fusion method driven by a rule engine. [0004] The embodiment of the application provides a data fusion method driven by a rule engine, which includes the following steps: [0005] Step 1. Set the expression standard of fusion rules; [0006] Step 2. Set the implementation specification of ...
