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。

However, long-term since, clean-fingered to basically leading a cadre take up a political career behavior undertakes be supervisoried effectively is a focus and difficulty problem all the time, the article undertakes was discussinged to this one problem.

然而，长期以来，对主要领导干部廉洁从政行为进行有效的监督一直是一个焦点和难点问题，本文对这一问题进行一点探讨。

Synopsis : Joel personality is no problem, But his life is a big problem -- a love for years Clementina girlfriend suddenly become the one pair of its own without the slightest feeling of strangers.

By transforming the nonlinear saturation constraint into the special linear constraint, the problem of solving the feedback controller with saturated actuator is converted to the design of controller with linear constraint. The stochastic stability is ensured by using the intersection of ellipsoid invariant set of different modes existing in the attraction domain of the closed loop system. In this case, solving controllers can be equivalent to a solvability problem of linear matrix inequalities.

通过将非线性饱和约束转化为特殊的线性约束，使具有饱和执行器的控制器求解问题转化为线性约束控制器的求解问题，利用位于闭环系统吸引域内的不同模态下椭圆不变集的交集来保证系统的随机稳定性，此时控制器的求解可等效为线性矩阵不等式的可解性问题。

It has a long history to study on the problem of best restricted range approximationin a space of real-valued continuous functions on a closed interval, while the corresponding problem in a space of complex-valued continuous functions on a compact metric space was just introduced in recent years.

三。实值连续函数空间中最佳限制值域逼近问题的研究有较长历史，而复值连续函数空间中相应问题的研究却是近几年来的事情。
