Patent Searching and Data


Title:
DATA UPDATE METHOD, AND COMPUTER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/125230
Kind Code:
A1
Abstract:
When new unit data is added to original graph data, a computer system identifies from meta information of contraction graph data a first contraction value which is a contraction value corresponding to a first node value in the new unit data and a second contraction value which is a contraction value corresponding to a second node value in the new unit data, and adds, to the contraction graph data, new unit contraction data combining the first contraction value, the second contraction value, and an edge from the first contraction value to the second contraction value (the same edge as an edge in the new unit data).
