面向相似度的多维异构数据比对模型研究

The Research on Comparision Model about Heterogeneous Data in Multidimensional Base on the Comparability

本文从应用角度出发,探索包含结构化数据、非结构化数据、时序数据、空间数据的大信息量多维异构数据相似性比对问题。即在不同的数据维度上采用主流、适合的算法,计算每个数据维度上的相似度,再从权重分配角度综合考虑,提出综合不同维度的大信息量异构数据相似度算法,从应用的角度,探索异构数据相似度比对的新思路。

Based on the application programe,this article researched the comparision of comparability about the information heterogeneous data in multimensional include the structuring data,unstructed data,sequence data and space data.It adopted maincurrent and applicable caculation in different data dimensionality,accounted the comparability of every single data dimensionability.Also apointed out the comparability arithmetic of information heteogeneous data in weight.This chapter advanced the new comparision mentality on heterogeneous data in multidimensional based on comparability from application.
