Technological advances dramatically changed the approaches in information representation and retrieval. There are two broad approaches to the knowledge representation; one is informal, dynamic, free, user-dependent and the other is formal, more stable, solid, static and system-dependant: Folksonomies a breed of the Web 2.0 and ontologies the backbone of semantic web (web 3.0) are two examples of those approaches. In this paper, we try to present two sub-models of an integrated system in which each technology has the opportunity to reduce its current limits, by exploiting the power phttp://pooya.um.ac.ir/research/shares/basicInfo/papers.php?F1=6#rovided by the other one. In order to develop sub-models, we present a simple ontology of folksonomy to show how different elements act in such a dynamic space, and how implicit relations emerge from implicit complex networks within the folksonomies.
