摘要
随着信息技术的发展,特别是物理信息系统、互联网、社交网络等技术的突飞猛进,数据爆炸性增长的同时,劣质数据也随之而来,数据可用性受到严重影响。近年来,学术界和工业界开始研究数据可用性问题,取得了一些的研究成果,但是针对互联网大数据可用性问题的研究工作还很少。文章从大数据的发展现状分析入手,概述了大数据可用性的挑战,探讨了大数据可用性方面的研究问题。通过机器翻译案例,指出了互联网大数据可用性增长的可能途径。
With the rapid development of information technology,especially the great progresses of Internet,cyber physi- cal system and social network, big data becomes ubiquitous, and the poor data appears simultaneously, which accompanies the tremendous increase of data volume, degrades the data quality and usability. Fortunately,there has been widespread concern about the data usability in both industrial and academic communities,and the recent research efforts on data us- ability have yielded some impressive results.However,there are only few works focusing on the usability of big data.In this paper,the challenges of big data usability are introduced first,and then the problems of usability are analyzed. Finally, the possible solutions for the data usability growth of internet big data are proposed.
