In this paper, we proposed a user modeling technique based on ontology for building social network. User modeling technique is composed of user ontology creation process for expressing user information and social network construction process that is applied closeness weight. User ontology schema is defined by expanding and refering the candidate schema of HR-XML and is created by OWL(Web Ontology Language). We created ontology instances using user ontology schema and defined a user ontology rule using SWRL(Semantic Web Rule Language) for supporting a reasoning service. And we analyzed an information of association connection attribute based on user ontology instance for represent semantic relation between users. In this paper, we computed a closeness between users using the information of association accomplishment and extracted direct relation that applied a closeness weight. We composed the user social network with closeness weight by expanding the direct relation between users.
