Abstract

The Internet of Medical Things (IoMT) will come to be of great importance in the mediation of medical disputes, as it is emerging as the core of intelligent medical treatment. First, IoMT can track the entire medical treatment process in order to provide detailed trace data in medical dispute resolution. Second, IoMT can infiltrate the ongoing treatment and provide timely intelligent decision support to medical staff. This information includes recommendation of similar historical cases, guidance for medical treatment, alerting of hired dispute profiteers etc. The multi-label classification of medical dispute documents (MDDs) plays an important role as a front-end process for intelligent decision support, especially in the recommendation of similar historical cases. However, MDDs usually appear as long texts containing a large amount of redundant information, and there is a serious distribution imbalance in the dataset, which directly leads to weaker classification performance. Accordingly, in this paper, a multi-label classification method based on key sentence extraction is proposed for MDDs. The method is divided into two parts. First, the attention-based hierarchical bi-directional long short-term memory (BiLSTM) model is used to extract key sentences from documents; second, random comprehensive sampling Bagging (RCS-Bagging), which is an ensemble multi-label classification model, is employed to classify MDDs based on key sentence sets. The use of this approach greatly improves the classification performance. Experiments show that the performance of the two models proposed in this paper is remarkably better than that of the baseline methods.
