In recent years, the research on Treebank has made great progress. However, the application of the Treebank research in international Chinese teaching is not very satisfactory. In view of international Chinese teaching, this paper constructs a diagrammatic Treebank based on the Li Jinxi's Sentence-based Grammar. With the constructing of the diagrammatic Treebank, we have made an exploration in word interpretation based on context, accurate example sentences recommendations based on word senses, words exercise based on dynamic word patterns, and specific grammar point example sentences recommendation.
