Abstract ：
近年来，基于深度学习模型的药物推荐在智慧医疗领域得到了广泛的研究和应用。提出了一种基于图嵌入的双层图卷积网络药物推荐模型。构建患者属性知识图谱和患者用药知识图谱，利用图嵌入生成嵌入表示，将患者属性知识图谱的嵌入表示放入加载了注意力机制和双向传播机制的多层图注意力网络层进行信息传播与融合，将得到患者的特征表示和患者用药知识图谱嵌入表示进行聚合，再次放入多层图注意力网络层训练，从而挖掘患者属性和患者用药之间的高阶关联，最终完成药物推荐。以重症监护医学信息数据库数据集中的患者基本信息、生理特征和患者用药数据作为对象开展实证研究。实验结果证明，其在推荐准确率、召回率、F1分数和NDCG四个评价指标上均优于基线方法。

Abstract ：
Acute complication prediction model is of great importance for the overall reduction of premature death in chronic diseases. The CLSTM-BPR proposed in this paper aims to improve the accuracy, interpretability, and generalizability of the existing disease prediction models. Firstly, through its complex neural network structure, CLSTM-BPR considers both disease commonality and patient characteristics in the prediction process. Secondly, by splicing the time series prediction algorithm and classifier, the judgment basis is given along with the prediction results. Finally, this model introduces the pairwise algorithm Bayesian Personalized Ranking (BPR) into the medical field for the first time, and achieves a good result in the diagnosis of six acute complications. Experiments on the Medical Information Mart for Intensive Care IV (MIMIC-IV) dataset show that the average Mean Absolute Error (MAE) of biomarker value prediction of the CLSTM-BPR model is 0.26, and the average accuracy (ACC) of the CLSTM-BPR model for acute complication diagnosis is 92.5%. Comparison experiments and ablation experiments further demonstrate the reliability of CLSTM-BPR in the prediction of acute complication, which is an advancement of current disease prediction tools.

Abstract ：
为了研究安全事故案例报告中上下文语义指代和复杂领域内容对机器自动识别与抽取信息的性能影响，通过考虑局部特征增强构建了BERT+Multi-CNN+BiGRU+CRF(BMulCBC)模型。BERT负责将非结构化文本转化输入，Multi-CNN和BiGRU负责向量局部特征与序列特征编码，CRF则负责完成准确的实体标签解码。研究结果表明：模型实体识别的精确率、召回率和F1值分别为65.94%,74.02%,69.75%,在精确率和F1值上皆优于同类对比模型。研究结果可为安全事故事理图谱推理提供理论支持。

Abstract ：
Energy supply policy quality is an important factor that would impact national energy security. While existing research conducted policy evaluation from the lens of performance assessment, less study has been devoted to evaluating energy supply policy from the perspective of policy making. This study takes the energy supply policy documents issued by China's central government during the '13th Five-Year Plan' period (2016-2020) as the research sample, and pioneers the use of the extended policy modelling consistency (PMC) index model combined with the text mining methodology to construct a policy evaluation index system with the characteristics of the energy supply policy which conducts a more in-depth quantitative evaluation of the energy supply policy documents. The results show that the average PMC index value of China's energy supply policies is 7.26, and the overall quality is high. The concerns of existing policies are mainly focused on reform and development planning, safety production management and project engineering construction, but there is still room for improvement in policy predictability, coordination of policy areas, clarity of policy basis and goals and comprehensiveness of policy tool combinations. Based on this, China should improve the comprehensiveness of its energy supply policy tool combinations in terms of policy design norm; strengthen policy predictability and coordination of policy areas in terms of policy implementation guarantee; and clarify the basis and goals of policies in terms of policy orientation enhancement, to provide a reference basis for the formulation and improvement of future energy supply policies and to realise the sustainable development of energy supply. This study takes the energy supply policies issued by China's central government during the '13th Five-Year Plan' period as the object of research and utilises the extended policy modelling consistency index model to conduct a multidimensional evaluation of energy supply policies. The results show that the overall quality of China's energy supply policies is high, but there is still room for improvement in terms of policy predictability, coordination of policy areas, clarity of policy basis and goals and comprehensiveness of policy tool combinations. Based on this, this paper gives the corresponding suggestions to provide a reference basis for the formulation and improvement of subsequent energy supply policies.image

Abstract ：
Background: Online medical and health communities provide a platform for internet users to share experiences and ask questions about medical and health issues. However, there are problems in these communities, such as the low accuracy of the classification of users' questions and the uneven health literacy of users, which affect the accuracy of user retrieval and the professionalism of the medical personnel answering the question. In this context, it is essential to study more effective classification methods of users' information needs.Objective: Most online medical and health communities tend to provide only disease-type labels, which do not give a comprehensive summary of users' needs. The study aims to construct a multilevel classification framework based on the graph convolutional network (GCN) model for users' needs in online medical and health communities so that users can perform more targeted information retrieval.Methods: Using the Chinese online medical and health community "Qiuyi" as an example, we crawled questions posted by users in the "Cardiovascular Disease" section as the data source. First, the disease types involved in the problem data were segmented by manual coding to generate the first-level label. Second, the needs were identified by K-means clustering to generate the users' information needs label as the second-level label. Finally, by constructing a GCN model, users' questions were automatically classified, thus realizing the multilevel classification of users' needs.Results: Based on the empirical research of questions posted by users in the "Cardiovascular Disease" section of Qiuyi, the hierarchical classification of users' questions (data) was realized. The classification models designed in the study achieved accuracy, precision, recall, and F1-score of 0.6265, 0.6328, 0.5788, and 0.5912, respectively. Compared with the traditional machine learning method naive Bayes and the deep learning method hierarchical text classification convolutional neural network, our classification model showed better performance. At the same time, we also performed a single-level classification experiment on users' needs, which in comparison with the multilevel classification model exhibited a great improvement.Conclusions: A multilevel classification framework has been designed based on the GCN model. The results demonstrated that the method is effective in classifying users' information needs in online medical and health communities. At the same time, users with different diseases have different directions for information needs, which plays an important role in providing diversified and targeted services to the online medical and health community. Our method is also applicable to other similar disease classifications.(JMIR Form Res 2023;7:e42297) doi: 10.2196/42297
