TFIDF-master
tf–idf, short for term frequency–inverse document frequency, is a numerical statistic that is intended to reflect how important a word is to a document in a collection or corpus.[1]:8 It is often used as a weighting factor in information retrieval and text mining. The tf-idf value increases proportionally to the number of times a word appears in the document, but is offset by the frequency of the word in the corpus, which helps to control for the fact that some words are generally more common than others.
Variations of the tf–idf weighting scheme are often used by search engines as a central tool in scoring and ranking a document s relevance given a user query. tf–idf can be successfully used for stop-words filtering in various subject fields including text summarization and classification.
One of the simplest ranking functions is computed by summing the tf–idf for each query term many more sophisticated ranking functions are variants of this simple model.

WinForm窗体及其控件的自适应
说明: 窗体自适应,统计原始窗体的位置和大小;缩放后Resize通过计算主窗体的大小,计算出长宽伸缩比例,然后再计算出来内部控件的起始点和长宽,过程通过递归完成,简单易行!(The window adapts itself and counts the position and size of the original window; after scaling, resize calculates the length and width scaling ratio by calculating the size of the main window, and then calculates the starting point and length and width of the internal control. The process is completed by recursion, which is simple and easy!)
