Abstract
An inference device includes processing circuitry to generate integrated information by combining items of information respectively belonging to domains different from each other included in dynamically changing external information by means of forward chaining by using knowledge information including information regarding a human's condition and information regarding a human's action and provided from a knowledge base and an inference rule provided from a rule database. Each of the items of information respectively belonging to domains different from each other is information that can be represented as a directed graph including a node and an edge. The integrated information is an integrated graph. The processing circuitry calculates an importance level of a node as a component of the integrated graph from a probability of arriving at the node in a stationary state reached by performing a random walk on the integrated graph or by using an algorithm of PageRank.
