| titleOfInvention | Product characteristic structure tree construction method based on comment text mining |
| abstract | The invention provides a product characteristic structure tree construction method based on comment text mining, and provides a novel and effective method for data mining research. The method comprises the following steps: 1, obtaining a corpus; 2, extracting product characteristics; 3, constructing a product characteristic structure tree; 4, quantitative analysis of product characteristics; and 5, expanding the product characteristic structure tree. At present, technologies related to obtaining of comment texts, extraction of product features and the like are mature, but deep research on the extracted product features is not carried out. The invention aims to research the relationship between product characteristics and the reaction of the product characteristics on the product quality characteristics, and develops the direction and provides the idea for the research after the product characteristics are extracted. By using the method of the invention, manufacturing enterprises can quickly and effectively know the use product information fed back by users, thus being beneficial to establishing a conversation between the enterprises and consumers, helping the enterprises to improve product design and expanding market share. |
