【摘要】 为解决我国烟草市场大数据中存在的体量大、维度多、分析难等问题,提出了一种基于时空网格的大数据处理及可视化方法。通过构建时空网格对烟草市场数据进行预处理,降低数据样本数量及维度;再通过时空网格计算和多种可视化技术对烟草市场发展态势进行可视化展示,实现快速、交互、可视的烟草市场大数据分析与挖掘。以烟草行业下行数据为实例分析了我国细支烟的发展态势,选取的3个规格细支烟的市场销售态势与全国销售态势基本一致;以广西中烟工业有限责任公司"真龙(珍品)"卷烟的销售数据为实例,展示了该规格卷烟在不同时段的销售态势。本方法为提高卷烟企业分析市场的能力与效率提供了技术支持。更多还原

【Abstract】 To deal with the challenges of big volume,multi-dimension,and difficulty in analysis for tobacco market big data,a preprocessing and visualization approach of tobacco market big data based on spatial-temporal grid was presented.First,it executes data preprocessing by constructing spatial-temporal grid to reduce the scale and dimensionality of data sample.Second,it visualizes the developing status of tobacco market by spatial-temporal grid calculation and multiple visualization technologies to achieve an effective,interactive,and visual analysis of tobacco market big data.The first study case used real market datasets of fine cigarette products in China tobacco industries for experiment,and the results showed that the selling status of three specifications was in accordance with the whole selling status in a national wide.The second study case used a real market dataset of a cigarette product Zhenpin(brand Zhenlong) from China tobacco Guangxi industrial for experiment and demonstrated its selling statuses in different seasons.The proposed approach provides technical supports for increasing the ability and efficiency in market analysis for tobacco enterprises.更多还原
