发布时间：2018-09-06 14:37
【摘要】：随着互联网的高速发展,越来越多的行业借助网络以获取更好的效益和结果,招标也是如此,越来越多的招标活动通过网络进行发布,以期让更多的人了解,加强竞争,可以让更有实力的人或企业接手。对于有实力或者急于扩展业务的企业来说,网络上的每一条招标信息都有可能会对他们带来巨大的利益,同时,错过一条招标信息也意味着可能损失了一个巨大的机会。但是,目前在网上获取招标信息比较麻烦,原因有以下两点:第一,信息分散,人们需要到很多招标网站上去进行信息查找;第二,信息数目巨大,要从海量信息中筛选出符合自己需要的信息费时费力。针对上述问题,本文设计和开发了基于网络爬虫和文本分类的招标信息汇总和推送系统。它主要有四个模块,一个是爬虫模块,能够从各大招标信息发布网站获取信息,并处理成统一格式存入数据库;一个是一般用户模块,所有人都可以通过系统门户网站浏览汇总后的招标信息,并且能通过多个条件进行搜索查询;一个是注册用户模块,注册用户可以设置自己关注的网站并设置相应关键词;最后一个是信息推送模块,推送程序对爬虫获取的消息进行筛选然后将符合用户要求的消息以邮件方式推送给用户。该系统能大大减轻用户负担,节省时间,具有较高的实际意义。最终,本人在严谨科学的分析和设计基础上,利用多种热门和前沿技术实现了招标信息汇总推送系统,通过它,用户可以方便地获得自己需要的招标信息。
[Abstract]:With the rapid development of the Internet, more and more industries rely on the network to obtain better benefits and results, and so is bidding. More and more bidding activities are published through the network in order to let more people understand and strengthen competition. Can let more powerful person or enterprise take over. For enterprises with the strength or eager to expand their business, every bidding information on the network may bring great benefits to them, at the same time, missing a bidding information may mean that a huge opportunity may be lost. However, at present, it is more difficult to obtain bidding information on the Internet because of the following two reasons: first, the information is scattered and people need to go to many bidding websites for information searching; second, the amount of information is huge. It takes time and effort to filter out information that fits your needs from a large amount of information. To solve the above problems, this paper designs and develops a bidding information aggregation and push system based on web crawler and text classification. It has four main modules, one is the crawler module, it can obtain information from the major bidding information publishing websites, and it is processed into a unified format to be stored in the database; the other is the general user module. All of them can browse the total bidding information through the system portal website, and can search and query through several conditions, one is the registered user module, the registered user can set the website of their own concern and set the corresponding keywords; The last one is the information push module. The push program filters the message obtained by the crawler and then pushes the message that meets the user's requirements to the user by mail. The system can greatly reduce the burden of users, save time, has a higher practical significance. Finally, on the basis of rigorous and scientific analysis and design, I use a variety of popular and cutting-edge technologies to realize the bidding information collection and push system. Through it, users can easily get the bidding information they need.
