Abstract: Using aviation safety big data as an example, this report describes the characteristics of complex big data, including its highly complex features such as massive volume, multiple sources, heterogeneity, high dimensionality, time-series nature, high frequency, imbalance, similarity, heterogeneity, distributed nature, privacy concerns, low quality, functional nature, and stream data. It further discusses some of the scientific research challenges that arise in this context.
