Problems solved by technology

[0004] In view of the fact that the current smart city evaluation methods are all-round measures of the city's wisdom, it is impossible to highlight the characteristics of a certain theme in a large and comprehensive index system. Therefore, a theme-oriented smart city index system is proposed. method

Embodiment 1

[0055] A subject-oriented smart city index system tailoring method, including the following steps:

[0056] Step 1, build an index system (such as figure 1 shown), the specific steps are as follows:

[0057] The data structure of the index item in the definition index system is: ID, Name, Sort, PID and Note, where ID is the number of the index item / index system, and its value is unique and cannot be empty; Name is the index item / The name of the indicator system; the value of Sort is divided into two cases: if the current data is an indicator system, its value is empty, otherwise, if it is an indicator item, it is the sort number of the index item at the same level under the same parent node; The value of PID is divided into two cases: if the current node is an indicator system, the PID is empty; otherwise, if it is an indicator item, its value is the number of the parent node; Note is the remark of the indicator item / indicator system.

[0058] Step 2, build a theme library ...

Embodiment 2

[0091] The present invention is a theme-oriented smart city index system tailoring method, based on the existing index system, combined with the theme characteristics, with the AHP as the core, through the field experts to assign scores, judgment matrix generation, feature decomposition, judgment matrix Steps such as consistency check and judgment matrix adjustment, and based on the threshold of the weight of the index item set in advance, cut out the index items that are not very relevant to the topic, and then update the weight of the index item under the topic to realize the theme-oriented index System tailoring. Finally, apply the tailor-made index system under this theme to evaluate the designated cities. The specific steps are as follows:

Abstract

The invention belongs to the field of big data analysis, and particularly relates to a theme-oriented smart city index system cutting method. In order to solve the problems that an existing index system is face-to-face but cannot highlight a theme, and an evaluation result based on the index system cannot reflect city characteristics. According to the the method, firstly, on the basis of the existing index system, the index system is constructed into a tree structure, and hierarchical and modularized management is performed on the index system; a characteristic theme inheriting a certain index system is created in a theme library; and an index weight under a certain theme is set by selecting weight setting under the theme in a theme library, a method for modifying the same-level index weight under the theme takes an analytic hierarchy process as a core, index items which are not related to the theme are cut off through a series of steps on the basis of a preset threshold value of the index item weight, and the weights of the index items under the theme are updated, so that theme-oriented index system cutting is realized.

Description

technical field [0001] The invention belongs to the field of big data analysis, and in particular relates to a subject-oriented smart city index system cutting method. Background technique [0002] In recent years, with the continuous improvement of city scale and urbanization level, a series of "urban diseases" such as traffic congestion, environmental pollution, unfair education and incomplete medical security, expensive medical treatment, lagging urban services, and unbalanced economic development have become increasingly serious. , people are increasingly calling for "how city managers use 5G, big data, cloud computing, Internet of Things and artificial intelligence and other new generation information technologies to build smart cities", hoping that smart cities relying on the latest information technology can give cities Governance brings new technical paths and governance solutions, making urban management more scientific, making citizens' lives better, making economi...
