Abstract
To provide a method, program, and system for converting graph data to a data structure that enables manipulations in various applications to be reflected in the original graph data. The method uses at least one graph matching pattern to convert at least a part of graph data including nodes and edges to a data structure as an image of a homomorphism thereof. A pattern is provided which includes one representative node variable having a first constraint that at most one node in the graph data matches the representative node variable; the node is prohibited from matching a node variable in another pattern. The method includes the step of performing matching between the graph data and the pattern to obtain a matching result that does not violate constraints including the first constraint, and the step of generating a data structure corresponding to the matching result that does not violate the constraints.
