Abstract:

Agricultural data is a kind of typical big data. If big data technology is applied in the field of agriculture information service, it will not only bring revolutionary progress for the agricultural information technology service, but also can promote the overall progress of agricultural industry. This paper summarized several problems for agricultural information service relating big data. We regarded that agricultural big data requires technological innovation of agricultural information service, mainly including three aspects: intelligent processing technology of agricultural big data, decision ontology technology of agricultural big data, human\|machine interactive technology of agricultural informationization cloud service. And the technology schemes and key research tasks were provided for each of the three aspects. The development and application prospects of big data on the field of agricultural information service are bright, which will accelerate the agricultural informationization, and promote the effective combination of industry\|university\|research, and is expected to realize breakthroughs in technology and application soon. National agricultural big data sharing alliance should be established, and big data\|based agricultural information service demonstrations should be carried out. It is necessary to support the fundamental researches vigorously by public funds.

Key words: the age of big data, agricultural big data, agricultural information service, technological innovation
