A computer-based method and device for parsing natural language syntactic structures. Natural language syntactic structures are parsed by building a matrix model and a linear model and constructing a recursive function through the mathematical thought of a composite function according to mathematical principles of subjects comprising the abstract algebra, the set theory, the combinatorial mathematics, the computability theory, the computational linguistics and the like and corresponding computer technologies; meanwhile, methods such as the mathematical induction are comprehensively applied to proving important conclusions. A set of brand new mathematical models are built for sentences of the natural language, and the thought is basically different from that of a conventional traditional method; two overall plug-in methods comprising a single-side same-direction order preserving method and a single-side same-direction non-order-preserving method are creatively provided, and a parallel syntactic constituent generating and processing method of a set family is creatively applied; the rules of the mathematics subjects and the computer subjects are sufficiently used, and the method has high accuracy and large operation amount, and has certain technological difficulty.
