【摘要】:在线机票预订网站上的用户查询量变化反应了民航市场需求的变化.通过对用户在线查询大数据的分析,可以及时准确地发现异常的民航需求,有利于机票代理及航空公司做出快速的市场反应.本文提出了一种新颖的民航异常需求发现方法,基于不同航线的用户查询量时间序列,并利用全国航线网络,从网络整体而非单条航线的视角来检测民航需求异常.基于某在线订票网站的真实查询数据集进行了实验,表明本文提出的方法能够有效地从用户查询行为记录中及时发现民航异常需求.
[Abstract]:The changes in the number of users querying on the online ticket booking website reflect the changes in the demand of the civil aviation market. Through the analysis of big data, a user's online query, the abnormal civil aviation demand can be found in a timely and accurate manner. This paper presents a novel method for detecting the abnormal demand of civil aviation, which is based on the time series of users' query on different routes, and makes use of the national airline network. The anomaly of civil aviation demand is detected from the perspective of the network as a whole rather than a single route. Based on the real query data set of a certain online booking website, the experiment is carried out. The results show that the method proposed in this paper can effectively detect the abnormal requirements of civil aviation in time from the user's query behavior records.
