Automatic text classification (TC) is essential for information sharing and management. Its ideal goals are to achieve high-quality TC: (1) accepting almost all documents that should be accepted (i.e., high recall) and (2) rejecting almost all documents that should be rejected (i.e., high precision). Unfortunately, the ideal goals are rarely achieved, making automatic TC not suitable for those applications in which a classifier’s erroneous decision may incur high cost and/or serious problems. One way to pursue the ideal is to consult users to confirm the classifier’s decisions so that potential errors may be corrected. However, its main challenge lies on the control of the number of confirmations, which may incur heavy cognitive load on the users. We thus develop an intelligent and classifier-independent confirmation strategy ICCOM. Empirical evaluation shows that ICCOM may help various kinds of classifiers to achieve very high precision and recall by conducting fewer confirmations. The contributions are significant to the archiving and recommendation of critical information, since identification of possible TC errors (those that require confirmation) is the key to process information more properly. 相似文献

对自然资源进行统一的科学分类是开展自然资源调查评价、履行其管理职责、编制国土空间规划、实施山水林田湖草的整体保护、系统修复和综合治理、实现自然资源治理能力现代化等重大战略任务的最基础性前期工作。针对学术界、管理层和实际工作者对自然资源分类的不同意见和分歧,本文创新性地从空间、属性、用途、管理等视角提出了一个含有3个一级大类、11种二级门类、62种三级类别的新分类框架和分类方案。该方案不仅区分了自然资源的地理空间,便于分类管理和实际操作,而且区分了自然资源的不同用途与属性,很好地反映了作为物质或能量的自然资源与作为环境条件的自然要素之间类型上的差异性。研究成果为推进自然资源分类体系的完善,并与国际接轨、提升自然资源治理现代化能力,以及推动自然资源管理部门与生态环境、农田水利、国土空间规划、城乡建设等部门在自然资源、国土空间、生态修复等重大任务和目标上的有机衔接,具有重要应用价值和现实意义。 相似文献

In recent years, Zero-shot Node Classification (ZNC), an emerging and more difficult task is starting to attract attention, where the classes of testing nodes are unobserved in the training stage. Existing studies for ZNC mainly utilize Graph Neural Networks (GNNs) to construct the feature subspace to align with the classes’ semantic subspace, thus enabling knowledge transfer from seen classes to unseen classes. However, the modeling of the node feature is single-view and unilateral, e.g., the bag-of-words vector, which is not enough to fully describe the characteristics of the node itself. To address this dilemma, we propose to develop the Multi-View Enhanced zero-shot node classification paradigm (MVE) to promote the machine’s generality to approach the human-like thinking mode. Specifically, multi-view features are obtained from different aspects such as pre-trained model embeddings, knowledge graphs, statistic methods, and then fused by a contrastive learning module into the compositional node representation. Meanwhile, a developed Graph Convolutional Network (GCN) is used to make the nodes fully absorb the information of neighbors while the over-smooth issue is alleviated by multi-view features and the proposed contrastive learning mechanism. Experimental results conducted on three public datasets show an average 25% improvement compared to baseline methods, proving the superiority of our multi-view learning framework. The code and data can be found at https://github.com/guaiqihen/MVE. 相似文献

对基于均衡约束数学规划(MPEC)的数据分类模型进行改进.在确定数据所服从分布的密度函数(高斯混合模型来模拟)的参数时,使用β似然估计来代替原模型中的最大似然估计.新模型可以克服似然函数可能出现无界的现象,在计算上有更好的鲁棒性.对于所得MPEC分类模型,使用filterSQP方法将其作为非线性规划求解.数值试验显示了新模型的有效性. 相似文献

When documentary material is indexed by a mechanized classification system, and the results judged by trained professionals, the number of documents in disagreement, after suitable adjustment, defines the error rate of the system. In a test case disagreement was 22% and, of this 22%, the computer correctly identified two thirds of the decisions as doubtful. Professional examination of this doubtful group could further improve performance. The characteristics of the classification system, and of the material being classified, are mainly responsible for disagreement, and the size of the computer-identified, doubtful, group is a basic measure of the suitability of the system for the test material being processed. If is further suggested that if two professionals were compared on the same material then their disagreements would be mainly over the same documents. 相似文献

We digitized three years of Dutch election manifestos annotated by the Dutch political scientist Isaac Lipschits. We used these data to train a classifier that can automatically label new, unseen election manifestos with themes. Having the manifestos in a uniform XML format with all paragraphs annotated with their themes has advantages for both electronic publishing of the data and diachronic comparative data analysis. The data that we created will be disclosed to the public through a search interface. This means that it will be possible to query the data and filter them on themes and parties. We optimized the Lipschits classifier on the task of classifying election manifestos using models trained on earlier years. We built a classifier that is suited for classifying election manifestos from 2002 onwards using the data from the 1980s and 1990s. We evaluated the results by having a domain expert manually assess a sample of the classified data. We found that our automatic classifier obtains the same precision as a human classifier on unseen data. Its recall could be improved by extending the set of themes with newly emerged themes. Thus when using old political texts to classify new texts, work is needed to link and expand the set of themes to newer topics. 相似文献
