Embodiment Construction

[0028] In order to make it easier for those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The theoretical basis of the present invention is established on the inextricably linked directly or indirectly between all things in nature, but for different application requirements, the subjects to be concerned about can often be summarized into a limited number of goals, so that The limited attention target is the root node, and other related information as its sub-nodes at different levels can form several information trees, so as to realize the orderly organization and intuitive expression of complex information in line with human thinking habits.

[0030] Dendrogram is an important nonlinear data structure, which exists widely in the objective world. A tree is a finite collection of n (n>0) elements, where:

Abstract

The invention relates to a knowledge base-based fast construction method of a common correlation information query tree. The knowledge base-based fast construction method comprises the following steps of: (1) constructing a correlation information logic tree structure of a business main body by taking the business main body as a root node according to business relations among various data in target data; (2) recording datasheets to which a father node and child nodes point, as well as correlation fields among the datasheets according to the correlation information logic tree structure; (3) constructing a knowledge base of the correlation information tree structure according to information of the correlation fields among the datasheets of the tree-like structure; (4) constructing a correlation information query function according to the knowledge base of the correlation information tree structure, and realizing the common correlation information query with a loose coupling degree in a recursive manner; and (5) reconstructing the correlation information of the business main body according to the correlation information logic tree structure. The method is suitable for all one-to-one table correlation business requirements; and by adopting the method, the construction efficiency of a complex business information extraction function can be greatly improved, and the fast adaptation to the adjustment of the business requirements can be realized.

Description

technical field [0001] The invention relates to a retrieval method for associated information, in particular to a method for quickly constructing a query tree of general associated information based on a knowledge base. Background technique [0002] Information retrieval, or Information Retrieval (IR), is a science dedicated to the effective storage and acquisition of large-capacity information. In practical applications, large-capacity information is reflected in the huge amount of data on the one hand, and the correlation between data on the other. complex. In the Internet age, public information facing the public is not only massive in quantity, but also has complex relationships among various types of information, and often these relationships exist implicitly, requiring further excavation and discovery. In the Internet age, there is an urgent demand for fast and high-quality information retrieval technology, and various intelligent retrieval technologies, especially ar...
