Correspondingly, assuming the output of JTrans is (t , the score function of JTrans(JGraph) becomes: The Guided Graph-based Joint Model: JGraph(JTrans) The Guided Transition-based Joint Model: JTrans(JGraph)  We can see that the feature functions are modified to include additional argumentst JGraph and d JGraph .
these models resolve the joint task by a two-step process: (1) constituent parsing and (2) rule-based transformation from constituent structures (CS) to dependency structures (DS).
