INTERACTIVE PROGRAM, SERVER, AND METHOD FOR INSERTING DYNAMIC INTERACTIVE NODE INTO INTERACTIVE SCENARIO

摘要

PROBLEM TO BE SOLVED: To provide an interactive program, a server, and a method for inserting a dynamic interactive node between fixed interactive nodes in an interaction which is as natural as possible.SOLUTION: A computers is made to function as: interactive scenario storage means for storing a plurality of fixed interactive nodes; dynamic interactive node storage means for storing a plurality of dynamic interactive nodes which can be inserted between interactive nodes; dynamic interactive node retrieval means for retrieving a predetermined number of dynamic interactive nodes having high probability of going transition from a sentence of a first fixed interactive node; return transition probability calculation means for calculating probability of return transition from a sentence of each retrieved dynamic interactive node to a second fixed interactive node; dynamic interactive node selection means for selecting a dynamic interactive node having a maximum combination of probability of going transition and probability of return transition under a predetermined condition; and interactive scenario advancing means for inserting the selected dynamic interactive node from the first fixed interactive node and advancing a scenario to the second fixed interactive node.
