Problems solved by technology

The rule-based method is relatively simple, but the biggest flaw is that these pre-set rules cannot be used across domains, and different types of products require different acquisition rules
[0005] Existing methods have great application defects, either they cannot meet the needs of cross-domain, or they cannot achieve a high recall rate

Embodiment Construction

[0026] In order to understand the present invention and its advantages more fully, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] First of all, what the present invention is given is a series of user comment information of specific products, which are stored as text format.

[0028] figure 1 is an example of the target review data, where the underlined words are the product parameter words to be obtained. For any given specific product name, the product name corresponds to a target review text and several product review texts in different fields.

[0029] Next, refer to image 3 , to illustrate the product parameter acquisition method according to the present invention.

[0030] like image 3 As shown, the product parameter acquisition method according to the present invention comprises steps:

[0031] A. Count and sort the occurrence frequency (namely word frequency) of each...

Abstract

The invention relates to a system and a method for acquiring product parameters, wherein the system comprises a target comment word frequency statistical unit, a product comment word frequency statistical unit, a correlation calculating unit, an expression pattern extraction unit and a matching unit, wherein the target comment word frequency statistical unit is used for carrying out statistics to all the word frequencies of each noun in an object comment and obtaining a word table; the product comment word frequency statistical unit is used for carrying out statistics to the word frequency of each word in a product comment and simultaneously, viewing the number of clauses of adjectives occurred in the word; the correlation calculating unit is used for calculating the correlation of each word in the word table; the expression pattern extraction unit is used for extracting the expression pattern of each product parameter in the target product comment and recording expression pattern tables; and the matching unit is used for finding product parameter words with low frequency of occurrences by matching the expression patterns in the target comment sentences.

Description

technical field [0001] The present invention relates to a system and method for acquiring product parameters, in particular to a system and method for automatically acquiring various parameters of products in field-oriented product reviews. Background technique [0002] At present, there have been some researches on automatically obtaining product parameters from product reviews, and there are mainly two methods: the method based on word frequency statistics and the method based on rules. [0003] The method based on word frequency statistics is mainly to count the occurrence frequency of each word or phrase in the comments, and use the noun or noun phrase with higher frequency as an alternative product parameter, and remove some noise through some denoising rules. The existing method based on word frequency statistics assumes that only products with high frequency of occurrence may be product parameters, but sometimes there may be product parameters with low frequency in th...
