Embodiment Construction

[0075] The technical solution proposed by the present invention will be further explained below in conjunction with the accompanying drawings.

[0076] The e-commerce commodity classification system based on the hierarchical combination model of the present invention is constructed through the python environment. The classification system of the present invention mainly includes four functional modules: a hierarchical classification thesaurus construction module, a data processing module, a classification matching module and a classification auxiliary module. The above four modules respectively complete the four process steps of the construction of the hierarchical classification thesaurus, data processing, classification matching, and auxiliary classification. The four major process steps together constitute the complete classification process of the e-commerce commodity classification system (hereinafter referred to as the system or classification system) of the present inve...

Abstract

The invention belongs to the technical field of Internet, and discloses an e-commerce commodity classification method and system based on a hierarchical combination model, and the method comprises thesteps: building a multi-layer classification lexicon or a hierarchical classification lexicon based on the hierarchical combination model; and matching the commodity titles subjected to word segmentation processing with a multi-layer classification word bank or a hierarchical classification word bank step by step from the uppermost level to the lower level, and finally determining the classification of the commodities by using paths or hierarchical classification tags according to a matching result. According to the classification method and system, on one hand, classification confusion of different categories of commodities with the same name is effectively avoided, and on the other hand, the problem of classification errors caused by noun stacking in titles is successfully solved.

Description

technical field [0001] The invention belongs to the technical field of the Internet and relates to commercial data processing technology, in particular to a method and a system for automatically classifying commodities on an e-commerce platform through a computer. Background technique [0002] At present, the development of the e-commerce field is still growing gradually, and the data generated can be said to be growing exponentially. All kinds of commodities emerge in endlessly. Due to the huge amount of data, manual classification has been difficult to achieve; therefore, it is necessary to use a computer classification system to complete the classification of e-commerce commodities. [0003] The computer classification system described in the present invention is not a management system disclosed in patent applications such as publication numbers CN1920831A and CN102915498A. The task of those management systems is to establish a commodity classification management system ...
