Abstract In this paper, a thematic knowledge map framework using Prefuse is designed. Through the co-word analysis, hierarchical clustering and TreeML file conversion, the themes of information retrieval based on the framework are mapped. Finally, information retrieval research is divided into five themes: intelligent information processing, search engines related, user behavior, information system research and content-based information retrieval.
