摘    要
 网络广告是指利用电子计算机联结而形成的信息通讯网络作为广告媒体，采用相关的电子多媒体技术设计制作，并通过电脑网络传播的广告形式。当前主要的网络广告形式有横幅广告、按钮广告、标志广告、悬浮广告、弹出广告、FLASH广告、对联广告等。
 2004年网络广告出现了一种新的广告形式，它就是内文广告，2006年下半年开始在国内网站上广泛传播。它的表现形式为高亮网页内某些关键词，浏览者如将鼠标移至这些广告词上，该广告词附近将显示一个广告窗口。该广告形式相对于其它形式有用户主动触发、广告相关度高、广告针对性强、广告种类多和不受站点页面广告位限制等优点。
 完整的内文广告系统由前端广告投放系统和后台管理系统组成，本论文设计并实现了内文广告系统的投放部分。该系统支持图文和纯文字两种形式的内文广告，并支持站点设置内文广告词颜色、广告投放区域和被屏蔽投放广告的关键词。
