MULTI-DIMENSIONAL CONTINUOUS UNCERTAIN XML DATA MODEL AND AGGREGATION QUERY ALGORITHM
摘要
Abstract
We present a p-document-based continuous uncertain XML data model.It supports the representation of uncertain XML data with multi-dimensional continuous random variables.We also present an efficient XML aggregation algorithm.It supports the XPath expression and selects appropriate aggregation method according to different types of continuous function.Experimental results show that this algorithm can effectively process the aggregation query supporting the multi-dimensional continuous XML data,and has very good scalability.关键词
