Based on this, a plurality of divided conference data are generated.

  The importance degree calculation unit 103 counts the number of appearances of the keyword extracted by the keyword extraction unit 101 for each character data of the divided conference data generated by the voice analysis unit 102. The importance calculation unit 103 grasps the period during which each slide is displayed based on the progress information acquired by the progress information acquisition unit 104, and for example, character data corresponding to the period during which the first slide is displayed. , The number of appearances of the keyword extracted from the first slide is counted. The number of appearances of the keyword in a certain divided meeting data calculated by the importance calculating unit 103 is regarded as importance information indicating the importance of the divided meeting data. FIG. 6 is a diagram illustrating an example of the number of appearances of keywords counted in the importance level calculation unit 103.

  The importance level prediction unit 106 is based on the importance level information calculated by the importance level calculation unit 103. The second importance level indicates a trend of importance levels in the period (second period) after the current time (second timing). Generate trend information. First, the importance level predicting unit 106 calculates the recording time for each importance level by adding the times of the divided conference data having the same importance level during the period from the start of the conference to the second timing (first period). For example, when the divided meeting data determined to have the importance level 25 is two pieces of the divided meeting data for 55 seconds and the divided meeting data for 41 seconds, the recording time of the importance degree 25 is 55 + 41 = 96 = 1 minute. 36 seconds. FIG. 7 is a diagram illustrating an example of the recording time for each importance level. Here, in each of the first, second, and third periods, information relating the importance and the total recording time of the divided conference data having the importance in each period is set as the importance of each period. The first importance level trend information, the second importance level trend information, and the third importance level trend information indicating the trend are defined.

  Next, the importance level prediction unit 106 confirms the progress of the content of the conference at the current time (second timing). Based on the progress information acquired by the progress information acquisition unit 104, the importance level prediction unit 106 confirms what number of all the slides the currently displayed slide is. At the second timing after 20 minutes out of 30 minutes, if 2/3 slides are displayed, the conference is progressing as scheduled, and if 2/3 slides or less are displayed, progress is made. Judge that it is late. Here, a case where 12 of 20 slides are displayed will be described.

  When 12 of the 20 slides are displayed, the number of sheets that should have already been explained is 20 × 2/3 = 13.3. And since 12 images were displayed in the previous 20 minutes, 8 images are displayed in the next 10 minutes, so the speed of presentation (number of displayed items per unit time) is (the next 10 minutes Speed) / (Current 20 minute speed) = (8/10) / (12/20) = 4/3.

  Here, in order to increase the speed of the presentation, the presenter is considered to omit the less important topics. Accordingly, the importance level prediction unit 106 omits the ¼ portion having a low importance level in FIG. 7. Therefore, the importance level prediction unit 106 calculates a cumulative value obtained by adding the occurrence ratio and the low importance level for each importance level (see (1) in FIG. 7).

  FIG. 8 is a diagram illustrating processing in the importance level prediction unit 106. The importance level prediction unit 106 identifies the importance level whose cumulative value exceeds 0.25 in (1) of FIG. 7 (24 in FIG. 8), and sets the occurrence ratio of the importance level below the importance level to 0 (FIG. 7). 8 (1)).

  Next, the importance level predicting unit 106 converts these occurrence ratios so that the total is 1. That is, in (1) of FIG. 8, since the total of the occurrence ratio is 0.74, the importance level predicting unit 106 multiplies each occurrence ratio by 1.00 / 0.74 to set the total to 1. (2) in FIG. 8 is generated, and second importance degree trend information indicating the importance degree tendency in the second period is generated. Then, by multiplying the remaining time of 10 minutes by each ratio, the occurrence time of each importance in the remaining 10 minutes (second period) is predicted ((3) in FIG. 8).

  The threshold generation unit 107 reproduces the conference data of 15 minutes (period a) in the remaining 10 minutes (second period, period b) based on the importance degree trend predicted by the importance degree prediction unit 106. An importance threshold is calculated. FIG. 9 is a diagram illustrating processing in the threshold generation unit 107. The threshold value generation unit 107, for the remaining 10 minutes (period b) predicted by the importance level prediction unit 106 for each importance level recording time prediction, has not been recorded and played back for 5 minutes (period c). Is added to the recording time calculated by the importance calculation unit 103, and the recording time in the conference data for 15 minutes (period a) to be reproduced is calculated ((1) in FIG. 9). By calculating the ratio for 15 minutes, the tendency of the importance level in the period a is calculated ((2) in FIG. 9).

  Based on the importance degree trend thus obtained, the threshold value generation unit 107 determines an importance degree threshold value for thinning out 5 minutes having a low importance degree. Specifically, in order to thin out 5 minutes (that is, 1/3) of meeting data from 15 minutes of meeting data, the threshold value generation unit 107 calculates the cumulative value of the occurrence ratios that are sequentially added from the less important ones. (3 in FIG. 9), the importance (25 in FIG. 9) having an accumulated value exceeding 1/3 is determined as the importance threshold. For each importance level, the threshold generation unit 107 calculates the total recording time of the divided conference data having an importance level equal to or higher than the importance level, and the total level is equal to or less than the length of the second period. The minimum importance may be set as the importance threshold.

  The conference data processing unit 108 processes the conference data stored in the conference data storage unit 112 based on the importance threshold determined by the threshold generation unit 107. Specifically, among the reproduction target conference data corresponding to the period a stored in the divided conference data storage unit 113, only the divided conference data having the importance level equal to or higher than the importance level threshold is connected to generate the processed conference data. . The generated processing conference data is stored in the processing conference data storage unit 114. The processing data stored in the processing conference data storage unit 114 is played back by the playback unit 109 and transmitted to the client terminal 200 via the communication unit 110.

  FIG. 10 is a diagram illustrating a configuration of the client terminal 200 according to the present embodiment. The client terminal 200 includes a period specifying information acquisition unit 201, a reproduction data output unit 202, and a communication unit 203. The period specifying information acquisition unit 201, the reproduction data output unit 202, and the communication unit 203 are realized as one function of a CPU that operates according to a program stored in a storage unit (not shown), for example.

  The period specifying information acquisition unit 201 is based on the operation of the user of the client terminal 200, when the user interrupts the reproduction of the conference data (first timing), and when the user resumes the reproduction of the conference data ( Period specifying information indicating the second timing) is acquired.

  The reproduction data output unit 202 outputs the reproduction data transmitted from the server device 100 to a display or a speaker provided in the client terminal 200.

  The communication unit 203 transmits the timing information acquired by the period specifying information acquisition unit 201 to the server device 100 and receives reproduction data transmitted from the server device 100.

  Next, operation | movement of the conference system 10 which concerns on this embodiment is demonstrated using a flowchart. FIG. 11 is a flowchart showing conference data processing in the conference system 10 according to the present embodiment.

  First, the server apparatus 100 acquires slide data (S1101), and the keyword extraction unit 101 extracts keywords from the slide data (S1102).

  When the server device 100 acquires the period specifying information from the client terminal 200 (S1103), the voice analysis unit 102 of the server device 100 performs a voice analysis process on the conference data stored in the conference data storage unit 112 and divides it. Conference data is generated (S1104), and importance information is generated for each divided conference data (S1105).

  The importance level prediction unit 106 generates the first importance level trend information and the second importance level trend information from the previous importance levels and the like (S1106), and the threshold value generation unit 107 generates the importance level threshold value (S1107).

  Then, the conference data processing unit 108 performs threshold determination on the divided conference data after the first timing (S1108), and executes processing conference data generation (S1109). The generated processing conference data is reproduced by the reproduction unit 109 (S1110), transmitted to the client terminal 200 via the communication unit 110, and output from the client terminal 200 (S1111). The conference data processing in the conference system 10 is thus completed.

  Although not explicitly shown in the flowchart, the conference data is sequentially accumulated even after the acquisition of the period specifying information in S1103, and the processes from S1104 to S1111 are sequentially executed on these data.

  With the above configuration, in the reproduction of a certain period of conference data, the divided conference data generated by dividing the conference data of the period is generated based on the trend of importance between the period and a period different from the period. A conference system 10 is provided that reproduces divided conference data selected based on an importance threshold. This invention includes the structure changed in the range which does not deviate from the meaning of the said embodiment, and is not limited to the said embodiment.

  For example, in the above embodiment, the configuration in which the conference data processing unit 108 connects the divided conference data as they are to generate the processed conference data is shown. However, the conference data processing unit 108 changes the playback speed of the divided conference data. A configuration may be provided, comprising means for comparing the importance threshold with a predetermined determination value, and means for changing the importance threshold when the importance threshold is greater than the determination value. For example, the threshold generation unit 107 generates the threshold. If the threshold value is larger than a predetermined value (a lot of divided conference data is thinned out), the importance level threshold is lowered to a predetermined value, and the playback speed of the playback unit 109 finishes playback within the conference time. It is good also as a structure which raises to the value defined based on such importance level threshold value. According to this configuration, it is avoided that the participant who listened to the reproduction becomes difficult to understand the content of the conference due to a lot of divided conference data being thinned out.

  In the above-described embodiment, the configuration in which the number of appearances of the keywords extracted by the keyword extraction unit 101 is regarded as the importance is shown. However, the present invention is not limited to this, and weights (coefficients) are previously assigned to the keyword candidates. A configuration may be adopted in which the value obtained by multiplying the number of appearances by the coefficient is defined as the importance, or the weighting of keywords may be determined based on the appearance format (bold and underlined) in the slide. According to this configuration, in the calculation of the importance level, the influence level of the keyword that seems important is increased, and as a result, the calculation of the importance level with higher accuracy, the generation of the importance level threshold value, and the processing of the conference data are performed.

  In the above-described embodiment, the configuration in which the importance threshold value calculated at the second timing is continuously used is shown. However, the progress information in the progress information acquisition unit 104 at a predetermined timing after the second timing is also shown. Acquisition, generation of the second importance trend information in the importance prediction unit 106, and generation of the importance threshold in the threshold generation unit 107 may be adopted. According to this configuration, after the importance level threshold is generated, even if the progress of the conference is different from the prediction at the second timing, the process according to the actual progress of the conference is executed.

  Further, the information processing apparatus further includes a configuration for acquiring position information indicating a location pointed by the presenter at the conference, and when the instruction word such as “this” is present in the character data generated by the voice analysis unit 102, the instruction word It is also possible to identify the word pointed based on the position pointed at the timing and the content of the slide, and calculate the importance after replacing the designated word with the pointed word.

  Moreover, it is good also as a structure further provided with the structure which acquires the information regarding the presenter's past presentation in a meeting, and calculates importance based on this information. For example, if the trend of importance distribution in the past announcement is calculated for every hour, and the tendency that the importance increases in the second half, for example, is read in the latter half of the newly calculated importance May be configured to increase the importance, or if the same announcement has been made in the past, the importance information in the previous announcement will be used, and the amount of computation newly performed in this announcement It is good also as a structure which reduces.

  In addition, for the slide data, for example, the presenter sets a weighting coefficient (weighting) for each of the pages, and the coefficient for the importance is calculated in the importance calculation corresponding to the period during which each slide is displayed. It is good also as a structure which multiplies.

  Further, in the above embodiment, a configuration is shown in which audio analysis or the like of conference data is executed after the period specifying information is acquired. However, for the conference data accumulated sequentially before the period specifying information is acquired, The voice analysis and the importance calculation process may be executed, or the voice analysis and the importance calculation process may be performed on the unprocessed conference data at a predetermined timing. With such a configuration, processing executed when the period specifying information is acquired is reduced, and processing conference data is generated more quickly.

  Moreover, in the said embodiment, although the structure which the server apparatus 100 performs to reproduction | regeneration of process meeting data was shown, this invention is not limited to this, The structure by which the process process of meeting data is performed by the client terminal 200, etc. The processing performed in the conference system 10 may be performed by another device in the conference system 10.

  The operations of the server device 100 and the client terminal 200 described here are realized by operating programs stored in the respective storage units. This program may be provided by communication, or may be provided by being stored in a storage medium such as a CD-ROM that can be read by a computer.
