Abstract

The article presents a preflow algorithm for the parametric minimum flow problem working in a parametric residual network with linear lower bound functions of a single parameter. On each of the iterations, the highest-label partitioning preflow-pull algorithm (H-L P P-P) pulls flow from an active node with the highest distance label over a conditionally admissible arc. After each pull of flow, either the parametric residual capacity of the arc or the parametric deficit of the node becomes zero for at least a subinterval of the parameter values. If the two situations take place in different subintervals, the algorithm is continued in two different parametric residual networks generated by this partitioning pull. The template-like structure of a dialogue act reveals a design where information about the items (part-of-speech) is a multiple section vector with one segment for each of the used part of speech categories. These categories are divided into groups, according to their importance regarding the task, enabling each segment to use its own representations for the words within it.
