- Abstract:
-
Online healthcare platforms have become increasingly important in meeting the basic medical needs of the public, especially with the growing popularity of smart healthcare. A crucial step in the online consultation process is helping patients find a doctor with relevant expertise, as this not only enhances patient satisfaction but also fosters the development of online healthcare platforms. Unlike traditional recommendation systems, doctor recommendations are subject to privacy protection, and historical records for each patient cannot be accessed. As a result, models can only utilize the most recent consultation records for training, leading to severe data sparsity issues. Similarly, during prediction, recommendations are made solely based on the patient’s current disease description. However, different patients describe their conditions in different ways, which results in varying recommendation effectiveness across patients. This may fail to meet the needs of some, thereby affecting the overall performance of the recommendation system. Along this line, in this paper, we proposed a novel method called Sequential three-way decision with data augmentation (STWD-NA), which combined both matching and mismatched interaction information for doctor recommendation to expand training data. Specifically, this novel method consisted of two parts. On the one hand, it proposed a method to integrate the mismatched interaction information to alleviate the cold-start problem during training. On the other hand, an algorithm was proposed based on the idea of sequential three-way decisions to dynamically adjust the model’s attention during the training process. Evaluation based on real-world dataset haodf.com demonstrates the utility and the effectiveness of the proposed method.
