The internet continuously produces large flows of data and form events sequences which convey knowledge about individuals’ profiles, communities, opinions, influences, intentions, and trends. Similarly, in areas such as healthcare, business, finance, defense, event sequences are generated conveying also a great deal of knowledge that can be used for social benefits, business intelligence, public security and national defense. Mining massive and complex sequence data for predictive analytics is the main purpose of this program. The data types addressed are multisource, characterized by heterogeneity, significant noise and missing values, high-dimensional and strong interrelations between their attributes.

互联网不断产生大量的数据流，并形成事件序列，这些事件序列传达了关于个人简介、社区、观点、影响、意图和趋势的知识。同样，在医疗保健、商业、金融、国防等领域，生成的事件序列也传达了大量可用于社会效益、商业智能、公共安全和国防的知识。挖掘大量复杂的序列数据进行预测分析是该计划的主要目的。处理的数据类型是多尺度的，其特征在于异质性，显着的噪声和缺失值，高维和它们的属性之间的强相互关系。
