- Abstract:
-
Formal and organized mining and clarifying of different categories of product improvement demands from online comments are necessary for the product improvement process. On considering the multilevel and multifeature nature of product design information, a topological analysis method based on a matter-element model used for hierarchical representation of online review product design information and identification of product improvement demands was proposed. PYLDAvis interactive visualization library was used to extract product elements from online comments, and the product elements were then divided into three levels, namely entity, function, and attribute. In addition, the matter-element model was used for hierarchical expression. The emotion inclination pointwise mutual information algorithm was combined to calculate the evaluation value of user opinions at all levels, and an affair–element model was used to express the user’s demand for the object features with low evaluation value. The correlation network analysis method was used to determine the relationship between defective matter elements, and the implication system analysis method was used to determine the realization of the product improvement demand. The case study took the online reviews of a health pot as an example, the user’s improvement demands for the product were found by mining online reviews, and means to achieve the demands were identified. A product improvement demand identification method incorporating topology and online comment mining can realize the hierarchical expression of user demands and clarify product improvement design information in a formalized and organized manner, providing a scientific basis and effective methods for identifying the improvement paths of products.
