METHOD FOR SUPPLYING USER INFORMATION STRUCTURE USING FUZZY NETWORK

摘要

PURPOSE: A method for supplying a user information structure using a fuzzy network is provided to supply an information structure with respect to a user by remodeling a preference of the user easily. CONSTITUTION: An information structure with respect to a user stored in a computer is converted into a hierarchical fuzzy network structure having a plurality of layers comprising at least one graph having at least one node(50). If information is inputted from the user, a node on the fuzzy network directly related to the inputted information is searched, and new preference of the node is calculated(52). Strength of a relation between each node in accordance with the new preference is calculated, and the new preference of each node in the graph is calculated in accordance with the strength of relation(54). In the case that a graph in the lower layer displays a detailed area of a node, the node is defined as a macro node. If a node is a macro node of a graph in the lower layer, preference change information(the first message) is transmitted to the graph of the lower layer(56). If the graph has a macro node in the upper layer, change information of all nodes(the second message) in the graph are transmitted to the macro node(58). If a graph receives the first message from the macro node, new preference with respect to all nodes in the graph is calculated. In addition, if a node in the graph is a macro node of a graph in the lower layer, the first message is transmitted to a graph of the lower layer(60). If a node receives the second message from a graph of the lower layer, new preference of the node is calculated(62).
