Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings.

[0023] figure 1 It is a flowchart of how to extract evaluation objects and assign weights to them in the commodity performance evaluation method guided by network evaluation texts. In this embodiment, it mainly includes the following steps:

[0024] Merchants collect all review text sets for sold items through agents.

[0025] Preprocess the collected online review text set. The preprocessing content includes removing stop words, using the Chinese Academy of Sciences Chinese word segmentation system ICTCLAS or CRF++0.54 to perform word segmentation and part-of-speech marking, and the preprocessed evaluation text data export for use;

[0026] According to the processed evaluation text data, extract the evaluation object set O=(o 1 ,o 2 ,...o n ), and calculate its TF-IDF value, take its natural logarithm and assign weight w to the e...

Abstract

The present invention provides a commodity performance evaluation method through network evaluation test guiding. The method comprises: a, obtaining all the evaluation tests of the commodity from the network aiming at the commodity requiring performance evaluation; b, performing preprocessing of the obtained commodity evaluation test, comprising works such as removing stop words, performing participle, marking phrase and the like; c, obtaining the evaluation object of the commodity according to the processed evaluation test, namely the commodity features which clients may pay attention to, and calculating the weight of the evaluation object; d, performing preprocessing of each comment of the commodity, constructing the evaluation object vector, and performing normalization processing; e, extracting the emotion words related to the evaluation object, and giving emotion polarity, and extracting the privative words and the adverb of degree related to the emotion word and giving a weight; and f, according to the obtained data, calculating the emotion polarity of each comment so as to obtain the emotion polarity of all the evaluation texts.

Description

technical field [0001] The invention relates to a commodity performance evaluation method, which is a commodity performance evaluation method guided by network evaluation texts. Background technique [0002] With the rapid development of e-commerce, online shopping has become a common phenomenon. However, due to the lack of direct contact with commodities in online shopping, checking other people's comments on commodities has become an important way for consumers to obtain commodity information. [0003] However, the current product evaluation system is not satisfactory. Most of the products adopt the method of good, medium and bad reviews. Although some products have parameters such as materials and other performance parameters, there are often performance characteristics that customers are concerned about. It is not included in the evaluation. At this time, it is necessary to check the comments of other customers one by one to dig out the information you need, which is ext...
