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.

、setting 配置信息说明
此 Demo 仅从功能上演示实现拖拽的基本方法和配置参数
1)、使用 拖拽功能，必须设置 setting.edit 中的各个属性，详细请参见 API 文档中的相关内容
2)、使用 拖拽功能的事件回调函数，必须设置 setting.callback.beforeDrag / onDrag / beforeDrop / onDrop 等属性，详细请参见 API 文档中的相关内容
基本拖拽设置：
允许复制 允许移动
setting.edit.drag.isCopy = true
setting.edit.drag.isMove = true
拖拽相对位置设置：
prev inner next
setting.edit.drag.prev = true
setting.edit.drag.inner = true
setting.edit.drag.next = true
2、treeNode 节点数据说明
对 节点数据 没有特殊要求，用户可以根据自己的需求添加自定义属性(、setting 配置信息说明

选择一个操作系统环境（Linux或者Windows），编制TCP/IP通信程序，完成一定的通信功能。例如：可以编一个程序和Unix的系统服务进行通信，如daytime（port 13）、echo（port7）服务等；或者两人talk，使用TCP/IP协议进行相互直接的发送和接收等。(Select an operating system environment (Linux or Windows), the preparation of TCP/IP communication process, the completion of certain communications. For example: you can compile a program and the Unix system services to communicate, such as daytime (port 13), echo (port7) services or two people talk, use the TCP/IP protocol to send and receive each other directly.)
