摘要
当前的计算机水平发展非常快速,面对着日益增长的大数据信息量,现在的
网络中的信息内容变得非常的臃肿,有价值的信息密度相对偏低,在众多的信息
中想要找到自己想要的信息是一件非常困难的事情,信息的拥堵时常出现。如何
在众多的信息量中找到有效的信息、有价值的信息是当下各大以互联网为生的企
业所一直研究的方向。而现在除了利用爬虫技术之外,通过自然语言、预料库、
知识图谱等方式来进行相关的知识归类、标记以及存储,方便人们在有需要时进
行很好的信息搜集功能的实现。
本次的设计就是通过以旅游城市为研究目标,通过以旅游城市关键词的相关
信息搜索为主要的开发功能,搭建一款用户只要输入城市名称就能够查看到城市
的旅游景点、美食情况等,并且通过以 Python 的技术来实现各个不同的旅游城
市的旅游资源图谱展示,更好的方便人们对于各大旅游城市的受欢迎程度、旅游
资源的丰富程度等进行很好的对比。通过以 B/S 结构来搭建这款网站,能够快速
的实现有效的整体开发,在关键词的搜索上可以实现非常快速的搜索效果实现。
关键词:旅游城市;关键词;Python

Abstract
The current level of computer development is very fast, facing the growing amount
of data information, now the information content in the network becomes very bloated,
and the density of valuable information is relatively low. It is very difficult to find the
information you want among the numerous information, and information congestion
often occurs. How to find effective information and valuable information in a large
amount of information is the direction that the major Internet-based enterprises have
been studying. In addition to the use of crawling technology, related knowledge is
classified, marked and stored by natural language, predictive database, knowledge map,
etc. to facilitate the realization of good information collection function when needed.
The design of this project is to set up a user who can see the city's tourist attractions,
food situation and so on as long as he input the city name through the development
function mainly based on the information search of the key words of the tourist city,
and to display the map of tourist resources of different tourist cities through Python
technology, which will make it easier for people to populate the major tourist cities.
The richness of tourism resources is well compared. By building this website with B/S
structure, we can quickly achieve effective overall development and achieve very fast
search effect on keyword search.
Key words: tourist city; Key word; Python
