皮尔逊指数计算

提出了一种自动构造特定领域本体的方法，该方法应用术语抽取和多重聚类技术。在术语抽取阶段，通过术语在专业语料与背景语料中出现概率的对比，采用LLR公式对术语进行评分，取得了更好的抽取效果。在层级关系发现过程中，采用上下文共现信息结合HowNet中词语的语义相似度，进行术语间相似度度量，力求获得术语间最合理的相关状况。同时改进了k-medoids聚类算法，更准确地发现术语的层级关系，进而构造出特定领域的本体。(This paper presents an approach to mining domain-dependent ontologies using term extraction and relationship discovery technology.There are two main innovations in the approach. One is extracting terms using log-likelihood ratio, which is based on the contrastive probabilityofterm occurrence in domain corpus and background corpus. The other is fusing together information from multiple knowledge sources as evidencesfor discovering particular semantic relationships among terms. In the experiment, traditional k-mediods algorithm is improved for multi-levelclustering. The approach to produce an ontology for the domain of computer science is applied and promising results are obtained.)

近30个VC++窗口界面设计控件用法集源码，比如滑块的使用、限制编辑框输入文本的长度、使用进度条、列表框、使用旋转按钮、通过控件窗口指针获得控件ID、在组合框中显示文件列表、通过控件ID获得控件窗口指针、在编辑框中追加文本等，都是简单实用的通用控件用法实例。

实验器材: 探索者STM32F4开发板 实验目的: 学习DS18B20数字温度传感器的使用. 硬件资源: 1,DS0(连接在PF9) 2,串口1(波特率:115200,PA9/PA10连接在板载USB转串口芯片CH340上面) 3,ALIENTEK 2.8/3.5/4.3/7寸TFTLCD模块(通过FSMC驱动,FSMC_NE4接LCD片选/A6接RS) 4,DS18B20传感器一个(接在PG9上). 实验现象: 本实验开机的时候先检测是否有DS18B20存在，如果没有，则提示错误。只有在检测到DS18B20之后才开始 读取温度并显示在LCD上，如果发现了DS18B20，则程序每隔100ms左右读取一次数据，并把温度显示在LCD 上。同样我们也是用DS0来指示程序正在运行。(Experimental equipment: Explorer STM32F4 development board Objective: Learn the use of DS18B20 digital temperature sensor. Hardware resources: 1, DS0 (connected to PF9) 2, serial port 1 (baud rate: 115200, PA9/PA10 connection on board USB to serial port chip CH340). 3 inch TFTLCD ALIENTEK, 2.8/3.5/4.3/7 module (via FSMC driver, FSMC_NE4 LCD chip select /A6 RS) 4, one of the DS18B20 sensors (attached to PG9). Experimental phenomena: This experiment first detects whether there is DS18B20 when starting up. If not, it prompts errors. Only after the detection of DS18B20 did it begin Read the temperature and display it on LCD. If DS18B20 is found, the program reads data once every 100ms or so and displays the temperature at LCD. On. Similarly, we also use DS0 to indicate that the program is running.)

参考源程序里最初的部分，后面的变量说明有详细解释，定义要评价的参数个数，评价的等级等，相应的在excel表格里的参数个数与评价等级的行数要与之对应。 PS:上面的代码里因子个数是通过跳出的对话框手动输入进去的。(Reference to the original part of the source program, the later variables explain the detailed explanation, define the number of parameters to be evaluated, the rating of the evaluation, and the corresponding number of parameters in the excel table and the number of rows of the evaluation grade.)
