1. Dartmouth researchers and their colleagues have created an artificial intelligence software that uses photos to locate documents on the Internet with far greater accuracy than ever before.
2. The new system,which was tested on photos and is now being applied to videos,shows for the first time that a machine learning algorithm（运算法则）for image recognition and retrieval is ac-curate and efficient enough to improve large-scale document searches online.The system uses pix- el（像素）data in images and potentially video—rather than just text-to locate documents. It learns to recognize the pixels associated with a search phrase by studying the results from text-based image search engines. The knowledge gleaned（收集)from those results can then be ap-plied to other photos without tags or captions（图片说明）,making for more accurate document search results.

Also, Web servers provide some additional information such as the type, length, and the last modification date of a document.

The Hypertext Transfer Protocol , the Web's ( ) protocol , is at the heart of the Web. HTTP is implemented in two programs : a ( ) program and a server program . The client program and server program executing on different end systems , talk to each other by (请作答此空) HTTP messages . HTTP defines how Web clients request Web pages from servers and how servers transfer web pages to clients . when a user ( ) a web page , the browser sends http request messages for the objects in the page to the server . The server ( ) the requests and responds with http response messages that contain the objects .

A.exchanging
B.changing
C.declining
D.removing

解析：

Web的应用层协议是超文本传输协议，是web核心。HTTP在两类程序（客户端程序、服务器端程序）中执行。客户端程序、服务器端程序在不同的终端系统中执行，通过交换HTTP消息来进行交互。HTTP定义了Web客户端如何从服务器端请求Web页面以及服务器端如何传送Web页面到服务器。当用户请求一个web页面，浏览器发送页面对象的http请求给服务器。服务器接收请求并用包含对象的http消息进行响应。
