抽取

In this paper, a novel two-dimensional kernel maximum scatter difference discriminant analysis (2D-KMSDA) is developed for the extraction of nolinear feature by using the well-known "kernel trick". It extracts much more effective nolinear feature and made the true recognition rate raise saliently. What's more, it also offers a unified framework for two-dimensional nolinear discriminant analysis.

本文通过引入著名的&核技巧&，将二维最大散度差线性鉴别分析扩展到非线性空间，提出了一种新的二维核最大散度差鉴别分析方法，该方法不仅抽取了图像中更加有效的非线性鉴别特征，使正确识别率显著提高，而且为二维非线性鉴别分析提供了一个统一的构架。

The question's semantic comprehension model combines many natural language processing techniques, including Segmentation and Part-Of-Speech Tagging, the confirmation of the question type, the extarction of keywords and extending, the confirmation of the knowledge unit, Through these works, the intention of the user is holded, which greatly helped the last work of this system. The FAQ-based question similarity match model is implemented by sematic sentence similarity computation, which is improved by our system, this model can answer frequently-asked question fastly and concisely.The document warehouse-base automatic answer fetching model fistly deal with the document warehouse beforehand and construct inversed index, then use high efficient information retrieval model to search in the base and return some relevant documents, lastly, we use answer extraction technique to get the answer from these relevant documents and present it to users.

问句理解分析模块采用分词和词性标注、关键词提取及扩展、问句类型类别确定等自然语言理解技术，实现对用户提问意图的准确理解；FAQ 库问句匹配模块主要采用本系统改进的句子相似度计算方法来实现用户问句的解答，该模块主要用于实现用户常问问题的快速、准确解答；学科文档库答案自动获取模块在对学科文档库建立倒排索引的基础上，采用高效的信息检索模型对索引库进行检索，返回与用户查询表达式相似度较高的文档作为候选文档，针对从文档中直接获取答案难度较大这一问题，本系统采用答案抽取技术来实现问题的最终回答。

在大鼠实验中，人工抽血及使用微量吸管抽取全血等手续皆会造成标准值的误差；我们会做多一些动物实验来降低此误差。

The robustness is obtained thanks to the fact that some local mismatches in the approach are generally impossible to change the global correct matching trend The method can not only be used for sectional images matching in medical field as it did in the thesis, but can also be used in other fields, such as stereo vision [2] Distance transformation plays quite an important role in object thinning and skeletonization in image processing.

2〗距离变换是一种基本的图象处理工具，它在实现目标细化、骨架抽取等方面起到重要作用。作者提出了一种统一化的距离变换，它能够快速实现多种距离测度的距离变换。当进行欧氏距离变换时，其平均误差远远小于文献中现有的方法，并且出现误差的概率也大大地降低了。

Distance transformation is a global operation on binary image which is widely used in skeletonization, shape matching, object reconstructing, obstacles elusion, etc.

距离变换是一种基于二值图像的全局操作，在骨架抽取、形状匹配、目标重建、机器人避障等图像分析与模式识别算法中有着广泛的应用。
