查询词典 classification

In the first approach the metadata extraction is viewed as a classification problem. Three statistic classification models, including Support Vector Machines, Perceptron with Uneven Margins, and Maximum Entropy are studied. The approach suffers from the problems of ignoring the variance in lengths of documents and ignoring the dependency of text units within documents. To solve the problems, our second approach takes the metadata extraction as a sequence data labeling problem and makes full use of the sequential information.

论文首先研究了基于分类的元数据抽取方法，考察了支持向量机、非对称间隔感知机和最大熵模型在ADME中的应用；然后针对分类方法中存在的忽略文档之间的差异、不考虑文档上下文等问题，提出了基于序列数据标注模型的抽取方法，并结合最大熵马尔可夫模型、投票感知机模型和条件随机场模型进行了研究；最后本文根据前两种方法的设计思想和优缺点，研究提出一种新的结构预测模型—— CDASP（Coordinate Descent Algorithm for Structure Prediction），并将其应用于元数据的自动抽取中。

In this paper, we prove that if Ф is parallel and A+G+μB=0 for some functions λ,μ, then Ф=0, which gives the classification of the hypersurfaces in S(superscript n+1) with parallel Mbius form and A+G+μB=0 from the classification theorem in paper of Li H.

本文证明了如果x的Mbius形式Ф平行，并且A+λG+μB=0，其中λ，μ分别是定义在M上的光滑函数，那么Φ=0，由此及李海中、王长平（2003年）文献中的分类定理给出了S(上标 n+1)中具有平行的Mbius形式及满足A＋λG+μB=0的超曲面的分类。

International classification of diseases is the standardized classification of medical information that is accepted all over world currently. However, there are still many problems of ICD in our country. The quality of ICD should be promoted and improved. Reinforcing the knowledge training of ICD in doctors, professional training of ICD and the sense of responsibility training in codifier is an important way to improve the quality of ICD.

国际疾病分类是目前国际公认的卫生信息标准分类，但是由于我国的ICD分类工作开展的时间还不是很长，推广还不够广泛和深入，目前我国应用ICD分类还存在很多问题，ICD分类质量有待进一步提高和完善，加强临床医师的ICD分类知识培训和编码人员的专业培训及责任心教育是提高ICD分类质量的重要途径。
