以专用词典为切分工具,建立以概念为基础的、具有主题分类特点的类目结构是中文信息动态自动聚类的一种适用方式。该文探索了基于控制词集的中文信息动态自动聚类技术,包括专用控制词集的构建,动态有限环境下的自动聚类程序、聚类算法,以及结合控制词集对聚类结果进行优化控制等,最后对实验结果给出了概要评价。  相似文献   

Fair and Explainable Depression Detection in Social Media     

《Information processing & management》2023,60(1):103168

Detection at an early stage is vital for the diagnosis of the majority of critical illnesses and is the same for identifying people suffering from depression. Nowadays, a number of researches have been done successfully to identify depressed persons based on their social media postings. However, an unexpected bias has been observed in these studies, which can be due to various factors like unequal data distribution. In this paper, the imbalance found in terms of participation in the various age groups and demographics is normalized using the one-shot decision approach. Further, we present an ensemble model combining SVM and KNN with the intrinsic explainability in conjunction with noisy label correction approaches, offering an innovative solution to the problem of distinguishing between depression symptoms and suicidal ideas. We achieved a final classification accuracy of 98.05%, with the proposed ensemble model ensuring that the data classification is not biased in any manner.  相似文献
