Problems solved by technology

However, its shortcomings are also very obvious: on the one hand, when the review comments containing multi-dimensional quality descriptions such as appearance, taste, and aroma are converted into a single score, the detailed information in the comments will inevitably be lost; The scale is too fine and does not match the expression of sensory quality differences in tea evaluation, making the judgment of the score more arbitrary
The above defects will amplify the influence of subjective factors in the conversion of comments to scores, and reduce the accuracy and stability of the results of tea quality comparison

Abstract

The invention discloses a method and system for comparing the sensory quality of tea leaves based on evaluation comments. The method includes: presetting comment words and their corresponding assignments; setting the term weight vector and Scale vector; obtain the Hadamard product of term weight vector and scale vector as the comment vector; extract the most value comment vector according to the comment vector of each sample in this batch; then calculate the maximum similarity according to the comment vector and the most value comment vector degree and the minimum similarity; based on the maximum similarity and the minimum similarity, calculate the sample score of each sample; judge the sensory quality of each sample by the size of the sample score. By adopting the invention, the accuracy and stability of the tea quality comparison results can be improved.

Description

technical field [0001] The invention relates to a natural language processing technology, in particular to a method and system for comparing sensory quality of tea leaves based on evaluation comments. Background technique [0002] The quality of tea mainly comes from the color, aroma, taste and shape of tea soup and dry tea. Sensory evaluation is the most intuitive, convenient and commonly used method to evaluate the quality of tea, and its results have a direct impact on the judgment of tea commodity value. [0003] Review comments are the carrier of tea sensory review results and the basis for comparison of tea quality. The standardized review comments generally cover the description of the characteristics and degree of the main sensory qualities in the appearance and inner quality of the tea. However, since reviews are textual information and contain various types of sensory descriptions, it makes direct comparison between reviews difficult, especially for a large numbe...
