抽取

On the basement of passband subsampling and digital downconvertion, according to QPSK with 30M carrier frequency and 8M bandwidth, digital IF channel is elaborately analyzed .

以对中频为30MHz，带宽为±4MHz的输入QPSK信号进行带通欠采样和数字下变频为基础，提出和分析了中频数字化通道的实现方案，进行了相应的多相低通抽取滤波器的设计，并针对数字中频信号就数字下变频模块进行了仿真，从而验证了整个下变频系统参数设计的可行性。

As an important component among information acquisition methods, the requirement for high quality auto-summarization system also becomes more urgency. To fulfill this requirement, an adapted Dotplot methods based on word sense quantization model is firstly provided to address the problem of subtopic segmentation. Then a multi-knowledge-sources-integrating model is constructed, which combines the results of rhetorical structure analyse, text content structure analyse and subtopic segmentation together and provides clues for abstract sentences extracting.

第四，互联网的普及增加了人们对信息获取速度、准确率的要求，也推动了人们对自动文摘系统的需求，为了进一步改进现有文摘技术，本文首先研究了基于语义量化模型的改进Dotplot隐式章节划分算法，然后通过加权有向图来构造了一个多知识源融合模型，模型能够融合文本修辞结构分析、内容层次结构分析以及隐式章节划分等多种知识源的分析结果，并以此为基础建立文摘语句的抽取算法。
