Abstract: In a routing design method for designing routing of a SiP having first and second routing portions that are connected to each other via bonding wires, whether a DRC error of the first or second routing portion is present or not is determined and the DRC error is selected when the DRC error is present. A plurality of nets associated with the selected DRC error are specified and the routes of the specified nets are removed. Then, bonding wire allocations of the specified nets are changed. Further, the specified nets are rerouted so as not to cause a DRC error and whether the rerouting result is accepted or not is determined.

Abstract: A first domain satisfying a first condition concerning a current utterance understanding result and a second domain satisfying a second condition concerning a selection history are specified. For each of the first and second domains, indices representing reliability in consideration of the utterance understanding history, selection history, and utterance generation history are evaluated. Based on the evaluation results, one of the first, second, and third domains is selected as a current domain according to a selection rule.

Abstract: A system or the like is provided that is capable of interacting with a user while appropriately eliminating an inconsistency between a user's speech and a recognized speech. According to the interactive system 100 of the present invention, an ith-order query Q1 for asking a user's meaning is generated based on an ith-order output linguistic unit yki related to an ith-order input linguistic unit xi (i=1, 2, --) included in the recognized speech. Thereby, it is determined whether there is an inconsistency between the user's meaning and the ith-order input linguistic unit xi on the basis of an ith-order response Ai recognized as a user's response to the ith-order query Qi.
