The entire disclosure of Japanese patent Application No. 2019-166815, filed on Sep. 13, 2019, is incorporated herein by reference in its entirety.

BACKGROUND

Technological Field

The present invention relates to a meeting support system, a meeting support device, and a meeting support program.

Description of the Related Art

In meeting, speech that is off topic from a predetermined subject hinders the progress of the meeting. Therefore, as a technology for smoothly supporting the progress of the meeting, there are technologies disclosed in, for example, JP 2011-66794 A, JP 2017-91535 A, and JP 2018-169651 A. JP 2011-66794 A describes the extraction, categorization, and counting of words matching or similar to any of predetermined affirmative or negative keywords or key phrases, determining whether a meeting progresses smoothly on the basis of a result of the extraction, categorization, and counting.

Furthermore, J P 2017-91535 A describes a meeting intelligence system that performs syntactic analysis of meeting content data to indicate an appropriate agenda topic, performs sentiment analysis to detect ongoing discussion that is to be interrupted, and generates a scheduling instruction.

Furthermore, J P 2018-169651 A describes referencing to an evaluation table registered for each meeting category, calculating a result per meeting elapsed time from the number of speakers and the speech time after the meeting starts, and evaluating the saturation of the meeting to issue an alert.

However, the technology described in JP 2011-66794 A cannot prevent a meeting from being off topic from a predetermined subject, even if the meeting has a content that is off topic from the subject, when the meeting progresses with approval from all speakers. Furthermore, the technology disclosed in JP 2017-91535 A may have a possibility that the progress of a meeting may be hindered due to a variety of topics, such as in a brainstorming meeting. Furthermore, the technology described in JP 2018-169651 A does not consider what is actually spoken in a meeting, and therefore, the progress of the meeting that is off topic from a subject cannot be prevented.

SUMMARY

Therefore, an object of the present invention is to provide a meeting support system, a meeting support device, and a meeting support program that sufficiently prevent a meeting from being off topic from a predetermined subject.

To achieve the abovementioned object, according to an aspect of the present invention, there is provided a meeting support system that supports the progress of a meeting, and the meeting support system reflecting one aspect of the present invention comprises: a hardware processor that: determines a first feature value based on information about a meeting, the first feature value corresponding to a range of a subject of a meeting, the information about a meeting having been registered in advance; stores a weight, the weight corresponding to each type of meeting; extracts a word or phrase from speech of participants in a meeting; determines a second feature value corresponding to the extracted word or phrase; and determines whether a speech is off topic from a subject of a meeting, depending on whether the second feature value is included in an allowable range, the allowable range being specified by the first feature value and the weight corresponding to a type of an ongoing meeting.
