Patent ID: 11449552

Abstract:
Provided is a search system that executes a path search in a graph (a material property relationship graph) in which each material property parameter of a material property parameter pair whose relationship is already known is node and a relationship between the material property parameters is an edge, the search method capable of executing various search methods and various search systems. The search system includes a graph searcher that executes a path search in a material property relationship graph, and a search condition extractor that supplies a plurality of search items to the graph searcher based on search conditions to be input. The search condition extractor extracts, based on the input search conditions, a start point or an end point or both a start point and an end point, and a third node different from the start point and the end point or a path length condition and supplies the extracted items to the graph searcher as a search item. The graph searcher, depending on the supplied search items, searches the material property relationship graph, and outputs a path or a subgraph that matches the search condition as a search result.
