An utterance content acquisition unit 31 according to the present invention acquires, from a Web conference system 20, utterance content data indicating content uttered by each user in a Web conference, along with a conference ID for identifying the Web conference, via a communication network 2. An utterance period acquisition unit 32 acquires, from a user terminal 10 of a user participating in the Web conference, utterance period data indicating a period of utterance by each user using each user terminal 10, a user ID for identifying the user, and a conference ID of the Web conference, via the communication network 2. A voice analysis unit 34 distinguishes between voiced speech segments and unvoiced segments in the utterance content data, by voiced speech segment detection specifies a start date and time and an end date and time of each of the voiced speech segments, further executes speech recognition processing with respect to utterance content data corresponding to the voiced speech segments, and outputs the speech recognition result, and also the start date and time and the end date and time (i.e. the period of utterance) of the speech. An identifying unit 35 identifies the period of utterance by each user and the user ID of that user. A registration unit 36 compares the period of utterance identified by the voice analysis unit 34 on the basis of the utterance content data stored in a storage unit 33 with the period of utterance identified for each of the users by the identifying unit 35, and registers each piece of utterance content data and the user who uttered the content indicated by the utterance content data in the storage unit 33 associated with each other.

Abstract

In an EMS server 100 according to the present disclosure, an electric mobility movement formulation unit 103, when it has been determined that a power supply to in-house equipment 200 (power consuming equipment) due to self-consignment of own company power generation equipment 300 is insufficient, detects an electric mobility group 400 (power supplier) on the basis of usage information (operational state) regarding the electric mobility group 400. If there is an electric mobility group 400 that can be used, the electric mobility movement formulation unit 103 compares the movement cost of moving the electric mobility group 400 to the in-house equipment 200 (power consuming equipment) and the purchase cost of purchasing external power by the in-house equipment 200. An electric mobility movement information transmission unit 104 issues a notification for moving the electric mobility group 400 on the basis of the comparison result.
