Establishment method and system for city management ontology knowledge base

Abstract

The invention provides an establishment method and system for a city management ontology knowledge base. The method comprises the steps of obtaining data sets of city management department systems and law and regulation documents related to departments; performing knowledge extraction on the data sets of the department systems and the law and regulation documents related to the departments according to a preset policy to obtain corresponding first knowledge entity set and second knowledge entity set; adding keyword tags and unique identifiers for all knowledge entities in the first knowledge entity set and the second knowledge entity set, establishing entity link relationships between the knowledge entities in the first knowledge entity set and the knowledge entities in the second knowledge entity set according to the keyword tags, and obtaining instances in the ontology knowledge base; and obtaining internet data matched with the instances, and establishing links between the instances and the corresponding internet data. According to the method and the system, the problem on information intercommunication among the departments is solved, and automated knowledge extraction and ontology knowledge base establishment are realized.

Description

technical field [0001] The invention relates to the technical field of knowledge engineering, in particular to a construction method and system for an urban management ontology knowledge base. Background technique [0002] With the accelerating process of urban informatization, people's production and lifestyle have undergone earth-shaking changes. People's requirements for urban service capabilities are also getting higher and higher, so the concept of smart cities came into being. Especially in terms of urban management, the public hopes that the government's governance methods will be more humane, and the municipal departments should no longer be pure urban managers, but should also transform into urban service providers. Therefore, it is particularly important to develop an ontology knowledge base application based on urban management with the help of knowledge engineering and related technologies, because it can effectively solve the above-mentioned bottleneck problems...

AI Technical Summary

Problems solved by technology

[0004] At present, people have carried out a lot of work on the construction of general knowledge bases, and the realization of existing ontology knowledge bases often has the following problems: the knowledge base is only constructed for a specific field; the data sources and formats required for building knowledge bases are also Relatively simple, mostly based on Internet data

Compared with knowledge in other fields, the amount of knowledge in the field of urban management is huge and the information is complex. In the process of building a knowledge base for massive data, there is still a problem of low query efficiency
