搜索引擎专辑之,网络树形搜索引擎的设计及其验证(Album of the search engine, Web search engine design tree and its verification)

说明：  这是学习python爬虫时的一个简单的例子，用于统计搜索引擎中关键词的答案数量(This is a simple example of learning Python crawler, which is used to count the number of key words in search engine)

网络爬虫抓取页面的链接，利用递归可以从该链接到达的页面继续获取链接(Web crawler recursively crawls pages link)

基于路岑呢的搜索功能，可以检索并建立索引等等(Search function based on Lucen, can search and build index, etc.)

舆情监控系统，设定关键字，利用搜索引擎自动搜索。(Public opinion monitoring system, set the keywords, the use of search engines automatically search.)

宝马E底盘汽车，加装原厂摄像头，CIC模块编成代码

搜索是网络技术的热门课题，网络爬虫是搜索技术的基础，用VC++编写的网络爬虫可以很好的学习这门课题，适合初学者(Search is a hot topic of network technology, network reptiles is based on search technology, using VC++ Prepared reptiles can be a very good network of learning in this subject, suitable for beginners)

说明：  搜索引擎及Web智能的经典书籍，很多该方向导师推荐的信息检索必读书目。(Classic book on search and web intelligence, which is recommended by a lot of Prof. on information intelligence.)

DBSCAN算法的重点是选取的聚合半径参数和聚合所需指定的MinPts数目。  在此使用球面距离来衡量地理位置的距离，来作为聚合的半径参数。  如下实验，选取2公里作为密度聚合的半径参数，MinPts个数为5.

说明：  自己写的一个关于python的小型爬虫，性能感觉还算可以。(Himself wrote a small crawler about python, performance feel return calculate can.)
