Problems solved by technology

At present, there is no method for data association network in the automobile industry. The automobile industry database has problems such as a large number of data fields, irregular names, and a wide range of data. The traditional data association is aimed at the establishment of data association within the same range, and is directly used for data association in the automobile industry. The network is not well established

Abstract

The embodiment of the invention provides a method and system for establishing an automobile industry data association network. The method comprises the following steps: unifying each field name of each item of data in an automobile industry database to obtain a field vocabulary set; comparing the data field names with the field vocabulary set to obtain a field name vocabulary; calculating a field name similarity matrix through the field name vocabulary, calculating a similarity matrix of each data application scene in the automobile industry database according to the application scene, and carrying out weighted summation on the name similarity matrix and the application scene similarity matrix to obtain a data correlation matrix; and determining a data association relationship matrix according to the data association degree matrix, and forming an automobile industry data association network by the data association relationship matrix. According to the embodiment of the invention, the relevance of the data is determined from the two dimensions of the data content and the data application scene, and the automobile data relevance network is established.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a method and system for establishing an automobile industry data association network. Background technique [0002] At present, the establishment of data association is mainly based on the correlation algorithm of association rules, the most classic ones are Apriori algorithm and FP-Growth algorithm. [0003] 1. The main idea of ​​the Apriori algorithm is: (1) Find frequent itemsets, use the non-empty subsets of frequent itemsets to be frequent itemsets, first find the candidate sets of frequent itemsets, and count the candidate sets, which is greater than the support The degree is the frequent set; (2) Generate association rules from frequent itemsets. For references, see Agrawal R. Srikant R. Fast algorithms for mining association rules. In Proceedings of the 20th International Conference on VeryLarge Databases [M]. Santiago, Chile, 1994: 487-499.
