[Objective] This paper presents an approach to construct interactive knowledge map that facilitates browsing and keyword searching. [Methods] Firstly, we modeled academic resources to reveal the implicit knowledge nodes and their complex relationship. Then, we built the interactive knowledge map based on user queries, which suggested associated terms and presented results in lattice. [Results] We examined the proposed method with documents from Proceedings of the International ACM SIGIR Conference in recent 10 years. We discovered hidden knowledge structure helping users locate core concepts and improve searching. [Limitations] The recommendation of relevant concepts needs to be improved. [Conclusions] The proposed interactive knowledge map help users effectively explore the information space.
