Embodiment Construction

[0025] Let the set of tax indicators be M={m i} n , the index m i The expression tree is T i =(V i , E i ); where V i is a set of nodes, which can be further expressed as V i ={m i}∪C i ∪D i , the index m i as an expression tree T i the root node of ; C i is the index m i The set of operation symbols in the evaluation expression of , as an expression tree T i The intermediate node of ; D i is the index m i The collection of data items in a computed expression, as an expression tree T i the leaf node; is the expression tree T i For example, for the indicator "power consumption rate", its calculation expression is "evaluation period electricity cost ÷ (evaluation period main business cost + ending inventory - beginning inventory)", and the root node of the corresponding expression tree is " "Power consumption rate", the intermediate nodes are "÷", "+", "-", and the leaf nodes are "Electricity fee during the evaluation period", "Main business cost during the ev...

Abstract

The invention discloses a tax intermediate index extraction method based on subtree pattern mining. The method includes the key steps that (1) all word strings of an aab format are found in postfix expressions of expression trees of tax indexes, so that all subtree patterns are identified; (2) expression trees of extremely large subtree patterns are established, and each expression tree is endowed with an intermediate index. According to the method, intermediate indexes can be utilized to replace a general character computational process frequently executed in tax index calculation, and therefore calculation of tax indexes is simplified.

Description

technical field [0001] The invention relates to a method for mining a maximal subtree pattern of a tax index calculation expression tree in tax data analysis, extracting tax intermediate indexes, and simplifying tax index calculation. Background technique [0002] Tax indicators are an important basis for identifying and tracking tax evasion, deepening tax information services, and optimizing tax policies. It involves tens of thousands of data items from different tax categories, different industries, and different database tables, and has two notable characteristics of complex mapping and redundant calculation. The former shows that each index contains 5-15 data items, and there are various arithmetic operation relationships between the data items, which brings great difficulties to the later index maintenance; the latter index has a large number of repeated calculation processes in the calculation. , for example, the calculation of the "business cost is abnormal in the inp...
