The author argues that the measurable distance between the core of the topic schema and an activated component within can well contribute to an assessment of discoursal continuity and inferential quantity, though the difference between the serial schema and the hierarchical schema should not be neglected.

作者认为，话题图式内诸成分之间的两种不同性质的距离，在保持话语连续性和支持语用推理时起重要作用，因为对话语连续性和语用推理量的折算，可以参考话题图式中被话语所激活的成分与话题图式中心成分的距离或与话题图式自身的认知紧密度。

The system parameters are determined by optimizing an output-error cost function. To deal with the non-uniqueness of the fully parameterized state-space system, a projected gradient search algorithm is presented by restricting the update of the parameters to the tangent space to the manifold of observationally equivalent state-space systems. The sufficient condition to employ L-M algorithm for optimizing parameters is also introduced. The proposed hierarchical optimization identificationmethod includes two steps: First, the parameter search direction is determined by the proposed adaptive L-M projected gradient approach; Second, the optimum step size is computed according to a line search method.
