摘　　要：大数据分析技术为多媒体信息处理提供支撑,研究大数据分析技术在多媒体信息处理中的应用对推动技术进步、发现潜在创新有着重要意义,而技术和创新大部分蕴含于专利中。利用汤森路透数据库检索并清洗得到956件专利,从专利信息视角挖掘该领域的发展态势。研究发现:中国专利申请量在全球占据第一的位置;重要技术主要集中在中国、美国和韩国;重点专利的关键词集中在多媒体、服务器、数据库、多媒体信息、数据采集等。研究进一步发现中国在该领域的专利很少布局在国外。因此,应加强原始创新以提高专利质量从而提升在国外的专利授权率。Big data analysis technology provided support for multimedia information processing.Research on the application of big data analysis techniques in multimedia information processing was of great significance to promoting technological progress and discovering potential innovations,and most of the technology and innovation were contained in patents.In this study,956 patents in this field were retrieved and cleaned from the Thomson Reuters database.Based on this,the development trend of this field was discovered from the perspective of patent information.The study found that the number of patent applications in China occupied the first position in the world;important technologies were mainly concentrated in China,the United States,and South Korea;the keywords of key patents fo-cused on multimedia,server,database,multimedia information,data collection,etc.The research further found that China's patents layout in this field were rarely abroad.Therefore,it was necessary to strengthen original innovation to improve the quality of patents and increase the rate of patent grants abroad.

关 键 词：大数据分析技术 多媒体信息处理 专利信息 挖掘
