A dialogue system, comprises an input unit configured to acquire utterance contents of a user in a dialogue; a mode determining unit configured to determine, based on the utterance contents acquired by the input unit, whether a mode of the dialogue is task-oriented or non-task-oriented; a plurality of intention understanding units each corresponding to a specific domain; and a domain determining unit configured to determine, when the mode of the dialogue is task-oriented, a domain of the dialogue based on a result of intention understanding of the utterance contents performed using each of the plurality of intention understanding units.

Dialogue system and domain determination method

A voice processing system includes a voice acquisition unit that acquires an utterance of a user, a voice recognition unit that recognizes contents of the utterance acquired by the voice acquisition unit, an execution unit that executes processing based on a result of the voice recognition unit, and a determination unit that determines a candidate of a word to substitute a certain word. When the voice recognition unit recognizes a request including a first word, the execution unit executes the request including the first word and provides the user with a processing result. The determination unit determines a second word that is a substitute candidate of the first word. The execution unit also executes a request including the second word instead of the first word and stores a processing result in a storage unit.

A keyword generation apparatus, comprises a vocabulary acquisition unit that acquires a keyword uttered by a first user; a first positional information acquisition unit that acquires first positional information including information representing a location at which the first user has uttered the keyword; a storage unit that stores the first positional information and the keyword in association with each other; a second positional information acquisition unit that acquires second positional information including information representing a current position of a second user; and an extraction unit that extracts a keyword unique to a locality in which the second user is positioned from the storage unit based on the second positional information.

Keyword generation apparatus and keyword generation method

The method includes the steps of: storing a plurality of parameter sets; selecting one of the plurality of parameter sets as a test parameter set to be evaluated; measuring performance only for one batch job out of N (N is a positive integer) batch jobs constituting full set performance measurement for the test parameter set; and calculating an evaluation value on the basis of a difference between an integral of measurement values obtained until the performance has been measured for r (r is a positive integer smaller than N) batch jobs by using the test parameter set; and an integral of mean measurement values of the performance for the r batch jobs by using an optimal parameter set which is one of the parameter sets used in the performance evaluation having been performed; determining whether or not the evaluation value has deviated from a predetermined evaluation continuing range; and terminating the evaluation of the test parameter set on condition that it is determined that the evaluation value has deviated form the evaluation continuing range toward performance deterioration. It is preferable that the predetermined evaluation continuing range be of a width from a width W where r is equal to zero, to a width W' (0&#x2266;W&#x2032;&#x3c;W) where r is equal to N. Furthermore, it is preferable that W&#x2032; be zero.

Method, program and apparatus for optimizing configuration parameter set of system

A method for analyzing performance of an information processing system having information processing apparatuses providing services to each other. Communication packets sent or received between the apparatuses are acquired. The apparatuses receive calls from other apparatuses for providing services indicated in the packets. A service call count aof the calls received by the apparatuses during period j of m periods for the service i of n services is computed. A busy time bis computed by summing processing times by the apparatuses for performing the services pertaining to the calls received by the apparatuses during period j. An average processing time dis computed by the apparatuses for each service i, as is an error &#x3b5;in dwherein &#x3b5;=b&#x2212;&#x3a3;ad, by minimizing an index indicative of &#x3b5;. The average processing time dis stored in a storage device and/or displayed on a display device.
