【摘要】：随着金融市场的蓬勃发展,国民生活水平的不断提升,越来越多的人开始关注金融领域的投资理财的发展,而金融资讯是获取金融领域的相关信息的第一途径,其重要性不言而喻。随着移动互联网的快速发展、科技的不断发展,形形色色的手机、平板、个人电脑以及高清屏幕等设备相继发展而来。人们获取信息的途径不再是单一的手机或者电脑,需要从不同途径获取信息的需求也越来越迫切。而随着互联网的快速发展,信息如爆炸一般蓬勃增长,当面对数据量极大的新闻资讯时,如何为用户提供第一手的热门有价值的新闻资讯,同样成为亟待解决的问题。针对如上三个方面的需求,本课题将对金融资讯的数据特点进行详细的分析,力求提供金融领域的热点新闻资讯,并能够从布局和资讯内容两个方面在主流的设备和终端上进行自适应展示的方法的设计与实现。基于布局的自适应展示,以响应式设计的开发方法为基础,运用弹性网格布局、媒体查询等,实现“一次设计,普遍适用”的布局自适应,并能实现可以拉伸拖拽的多样化网格模板的定制。基于内容的自适应展示,以金融热点资讯的发现为内容支撑,详细地分析金融资讯数据的新闻资讯特点以及金融领域数据特点,运用话题检测及跟踪技术中的关键词提取、文本聚类等方法,最终实现对金融热点资讯的发现及热点资讯的热度排序。并且对网格模板中各网格的大小及位置进行评价和分析,得到网格模板中各网格的重要性排序。根据发现的热点资讯、热点资讯的热度排序以及网格的重要性排序,最终将热点金融资讯按照资讯的热度自适应地展示在网格模板之中。
[Abstract]:With the vigorous development of the financial market and the continuous improvement of the national living standard, more and more people begin to pay attention to the development of investment and financial management in the financial field, and financial information is the first way to obtain the relevant information in the financial field. Its importance is self-evident. With the rapid development of mobile Internet and the development of science and technology, a variety of mobile phones, tablets, personal computers and high-definition screens have been developed. People's access to information is no longer a single mobile phone or computer, the need to obtain information from different ways is increasingly urgent. With the rapid development of the Internet, the information explodes like a booming growth, when facing the huge amount of news information, how to provide users with first-hand hot and valuable news information, also become a problem to be solved. In view of the above three demands, this topic will make a detailed analysis of the data characteristics of financial information, and strive to provide hot news information in the financial field. And the design and implementation of adaptive display method in the mainstream devices and terminals from layout and information content. Adaptive display based on layout, based on the development method of response design, using flexible grid layout, media query and so on, to realize the layout adaptation of "once design, universal application". And can be able to stretch and drag a variety of grid template customization. Based on the adaptive display of content, supported by the discovery of financial hot information, this paper analyzes in detail the characteristics of financial information data news information and financial domain data, and uses topic detection and tracking technology to extract keywords. Text clustering and other methods are used to realize the discovery of financial hot information and the ranking of hot information. The size and position of each grid in the grid template are evaluated and analyzed, and the importance ranking of each grid in the grid template is obtained. According to the hot spot information, the heat sort of hot information and the importance of grid, the hot spot financial information is displayed adaptively in the grid template according to the heat of the information.
