Method for modeling layered network knowledge model and method for establishing knowledge warehouse system

Abstract

The invention discloses a method for modeling a layered network knowledge model, which comprises the following steps of: confirming a knowledge field to be modeled; establishing a knowledge model of the knowledge field; and detecting whether the knowledge model is logic or not. The invention also discloses a method for establishing a knowledge warehouse system by utilizing the knowledge model, comprising the following steps of: establishing a knowledge database group for storing knowledge concepts and examples thereof; establishing a non-knowledge database for recording the storage position of each example in the knowledge database group; and establishing a knowledge edition database for managing different knowledge editions in the knowledge warehouse. The invention uses the layered network knowledge modeling method to facilitate data modeling, provides maximum expandability for knowledge models and organizes all knowledge related in the system by adopting distributed storage and multi-computer automatic mutual backup strategies to form a data warehouse in a true meaning, thereby improving the robustness, the fault tolerance and the recoverability of the whole system.

Description

technical field [0001] The invention relates to the technical field of e-commerce, in particular to a modeling method of a layered network knowledge model and a method for establishing a knowledge warehouse system. Background technique [0002] Unlike most Internet applications based on document presentation, e-commerce systems need to store and process large amounts of data. These data include product information, business information, buyer information and transaction logistics information. How to safely and efficiently integrate and analyze these data on a logical level is the primary problem faced by e-commerce systems. In addition, how to improve the information processing intelligence and automation of the system to reduce system R&D and maintenance costs, and shorten the R&D cycle are also key factors that determine the success or failure of e-commerce system operations. [0003] As we all know, current e-commerce systems and other Internet application systems use r...
