SUMMARY OF THE INVENTION

Technical Problem

The present invention intends to provide a presentation support system capable of giving effective presentations even when presentations are mechanically given or by ordinary presenters.

Solution to Problem

The same presentation materials (e.g., PowerPoint (registered trademark)) were used in doing business by a plurality of medical representatives (MRs), cram school teachers, and sales persons. As a fact, in the case of excellent presenters such as excellent MRs, excellent cram school teachers, and excellent sales persons, there was a certain pattern in the appearance order of keywords in each page of respective presentation materials. On the other hand, in the case of poor presenters, it was difficult to find any pattern in the appearance order of keywords.

The above-described problem is basically based on the knowledge that it is possible to determine an optimum order in the usage of keywords, about a certain presentation material, through processes of recording sounds in a presentation by a presenter suitable for a certain situation, analyzing terms included in this presentation, and analyzing the appearance order of keywords included in the analyzed terms. The present invention is based on the knowledge that a predetermined level of quality can be ensured by clearly indicating the registration order of keywords in explanations by excellent presenters, even when the presentations are mechanically given, or even when the presentations are carried out by ordinary presenters.

An invention described in this specification relates to a presentation support system. This system is a system using a computer.

This system includes a display unit3, a material storage unit5, a voice storage unit7, a voice analysis unit9, a keyword order adjustment unit11, and a display control unit13. Respective units in this specification can be realized by respective means and elements in the computer. They may be realized as software or hardware, or may be realized in the form of cooperation of software and hardware.

The material storage unit5is an element for storing one or more presentation materials and a plurality of keywords relating to the one or more presentation materials.

The voice storage unit7is an element for storing presentations including voice information relating to the one or more presentation materials.

The voice analysis unit9is an element for analyzing terms included in the presentations stored in the voice storage unit7.

The keyword order adjustment unit11is an element for analyzing an appearance order of a plurality of keywords included in voice analyzed by the voice analysis unit9and changing an order of the plurality of keywords based on the analyzed appearance order.

The display control unit13is an element for controlling contents displayed on the display unit3. The display control unit13performs control for displaying the plurality of keywords on the display unit3based on the order of the plurality of keywords changed by the keyword order adjustment unit11.

In a preferable example of this system, the material storage unit5further stores explanatory texts relating to the one or more presentation materials. The explanatory texts relating to the one or more presentation materials include a plurality of keywords. In addition, the system1further includes an explanatory text update unit15configured to update the explanatory texts based on the order of the plurality of keywords changed by the keyword order adjustment unit.

In a preferable example of this system, the material storage unit5further stores one or a plurality of relevant words relating to each keyword of the plurality of keywords.

In addition, the system further includes a keyword adjustment unit17. The keyword adjustment unit17is an element for adjusting the plurality of keywords stored in the material storage unit5, for each of the plurality of keywords, based on the terms analyzed by the voice analysis unit such that when a relevant word of one keyword included in the plurality of keywords is determined to be used more frequently than the one keyword, the relevant word is regarded as a new keyword instead of the one keyword.

A preferable example of this system further includes a keyword candidate extraction unit19. The keyword candidate extraction unit19is an element for analyzing a frequency of a term other than the plurality of keywords or the relevant words about the terms analyzed by the voice analysis unit9and extracting a term whose frequency is high as a new keyword or a new keyword candidate.

In a preferable example of this system, the material storage unit5further stores one or a plurality of relevant words relating to each keyword of the plurality of keywords. Further, when a relevant word of one keyword included in the plurality of keywords is used more frequently than the one keyword, this system (or the keyword candidate extraction unit19of this system) extracts the relevant word as a new keyword candidate, for each of the plurality of keywords, based on the terms analyzed by the voice analysis unit.

A preferable example of this system further includes an alert output unit21configured to output an alert when a term included in the presentation analyzed by the voice analysis unit9disagrees with the order of the plurality of keywords.

Another invention described in this specification relates to a computer program. This program is a program for causing a computer to function as the above-described presentation support system. Specifically, this program is a program that causes the computer to function as a presentation support system that includes display means, material storage means for storing the one or more presentation materials and a plurality of keywords relating to the one or more presentation materials, voice storage means for storing one or more presentations including voice information relating to the one or more presentation materials, voice analysis means for analyzing terms included in the one or more presentations stored in the voice storage means, keyword order adjustment means for analyzing an appearance order of a plurality of keywords included in voice analyzed by the voice analysis means and changing an order of the plurality of keywords based on the analyzed appearance order, and display control means for controlling contents displayed on the display means, wherein the display control means performs control for displaying the plurality of keywords on the display means based on the order of the plurality of keywords changed by the keyword order adjustment means. This program is, for example, for causing the computer to function as the above-described system.

Another invention described in this specification relates to a computer readable information recording medium storing the above-described program.

Advantageous Effects of Invention

The present invention can provide a presentation support system capable of giving effective presentations, even when presentations are given mechanically or by ordinary presenters.
