In this paper, the following tasks have been accomplished: (1) Analyzing the constraint relation of parts to accomplish Oriented Functional Relationship Graph (OFRG) assembly modeling.
The constraint-based theories Head-driven Phrase Structure grammar (HPSG) and Lexical Functional Grammar (LFG) integrate syntax and semantics in the account of anaphoric study.
