Abstract
A graph updating device includes: a K neighbor vertex search unit that searches for a K neighbor vertex set of an added vertex in a neighbor graph on the basis of the neighbor graph and an object added to the neighbor graph as an added vertex and outputs the K neighbor vertex set; a vertex selection unit that selects a vertex candidate set on the basis of the neighbor graph, the added vertex, and the K neighbor vertex set of the added vertex and outputs the vertex candidate set, the vertex candidate set being a set of vertices that is present in the neighbor graph and possibly contains the added vertex in a K neighbor vertex set thereof; and a neighbor graph updating unit that reconstructs a K neighbor vertex set related to all vertices of the neighbor graph using K neighbor vertex sets of respective vertices of the vertex candidate set and adds the K neighbor vertex set of the added vertex to the reconstructed K neighbor vertex set to generate an updated neighbor graph.
