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。

As they are evenly dispersed throughout genomes, usually characterized as codominant and highly polymorphic systems amenable to genotyping by polymerase chain reaction, and generally inherited in a Mendelian fashion, microsatellites have become instrumental as genetic markers in many areas.

摘 要：微卫星标记广泛分布于原核生物和真核生物基因组中，具有密度大、多态性丰富、遵循孟德尔分离定律共显性遗传、易于PCR扩增等特点，已成为近年来最引人注目的新型DNA标记。

STR locidistribute extensively and have higher information, polymorphism, and its heredity is based on Mondel codominant inheritance. We usehalf-quantitative analysis of STR polymorphism loci, to set up a clinicalpractical method that is highly accurate in rapidly detecting and prenatalgene diagnosing Down syndrome.

STR广泛分布于人类基因组中，一般认为，人类基因组平均每6～10Kb就有一个STR基因座，STR有高度多态性并遵循孟德尔共显性遗传，具有操作简便、分型准确和丰富的多态信息量等特点，已成为第二代DNA分析技术的核心。
