[Figure 7] This is a schematic diagram showing an example of displaying the viewer list section on the lecture analysis results screen presented by the management server in a lecture analysis system according to one embodiment of the present invention. [Figure 8] This is a schematic diagram showing an example of a lecture comparison screen presented by a management server in a lecture analysis system according to one embodiment of the present invention. [Modes for carrying out the invention]

[0011] First, with reference to Figure 1, the overall configuration of the lecture analysis system 1 according to an embodiment of the present invention will be described. As shown in Figure 1, the lecture analysis system 1 consists of an organizer's device 2 for the organizer of the lecture, a speaker's device 3 for the speaker to give the lecture, a distribution server 4 for distributing the lecture, a viewer's device 5 for viewers to attend the lecture, and an analysis server 6 for analyzing the lecture, all of which are connected via a network 7 such as the Internet.

[0012] In Figure 1, an example is shown where one analysis server 6 has one organizer device 2, but the conference analysis system 1 may have multiple organizer devices 2. In Figure 1, an example is shown where one analysis server 6 has one distribution server 4, but the conference analysis system 1 may have multiple distribution servers 4, and these multiple distribution servers 4 may belong to the same distribution provider or to different distribution providers. In addition, in Figure 1, one speaker device 3 and one viewer device 5 are shown, but the conference analysis system 1 may have multiple speaker devices 3 and multiple viewer devices 5.

[0013] Lecture Analysis System 1 is a system that analyzes lectures held in the same industry using an analysis server 6. For example, it analyzes lectures held by competitors that manufacture and sell similar products (for example, competitors in the medical and pharmaceutical industry). The speakers are not limited to competitors, but can be a wide range of industry stakeholders such as users of the products or evaluators who evaluate the products. For example, speakers at a lecture in the medical and pharmaceutical industry are not limited to those belonging to pharmaceutical companies, but can be doctors, pharmacists, researchers, university professors, and other various stakeholders in the medical and pharmaceutical industry. Similarly, the audience is not limited to product purchasers or competitors, but can be various industry stakeholders. For example, the audience at a lecture in the medical and pharmaceutical industry is not limited to doctors or employees of other companies, but can be various stakeholders in the medical and pharmaceutical industry. Each lecture may have one lecture, or it may have two or more lectures.

[0014] The organizer's device 2 is a device owned by the organizer of a given lecture, and consists of, for example, a personal computer, smartphone, tablet terminal, etc. In this embodiment, the organizer is not limited to the person holding the lecture, but also includes related parties and competitors on the organizer's side.

[0015] The organizer device 2 is configured to include, for example, a control unit 10, a storage unit 11, a communication unit 12, a display device 13, and an operation device 14. The control unit 10 is composed of a computer such as a CPU so as to comprehensively control the overall operation of the organizer device 2, and is connected to the storage unit 11 and the communication unit 12. The storage unit 11 is composed of a recording medium such as a ROM, a RAM, a hard disk drive, etc., and stores programs and data for controlling various components and various functions of the organizer device 2.

[0016] The communication unit 12 is an interface for the organizer device 2 to connect to a network 7 such as the Internet, that is, the organizer device 2 is connected to the analysis server 6 via the network 7. The display device 13 is composed of a liquid crystal display or the like, and displays various screens under the control of the control unit 10. The operation device 14 is composed of operation keys, a pointing device, etc., and receives input operations from the organizer. Note that the display device 13 and the operation device 14 may be composed of a touch panel.

[0017] The organizer device 2 receives the input, editing, and registration of organizer information (for example, organizer identification information (ID), organizer name, organizer affiliation, organizer title, etc.) regarding the organizer, and transmits the input organizer information to the distribution server 4 via the network 7 for registration. Also, the organizer device 2 can manage the seminars distributed by the distribution server 4 by logging in to the distribution server 4 using the organizer ID of the organizer information registered in the distribution server 4, and can present the analysis results of the seminars by the analysis server 6 to the organizer by logging in to the analysis server 6 using the organizer ID of the organizer information.

[0018] Specifically, as the analysis result of the seminar, the organizer device 2 is presented with an analysis screen described later from the analysis server 6 via the communication unit 12 and displayed on the display device 13. The organizer device 2 accesses the web browser provided by the analysis server 6 via the communication unit 12 to display the analysis screen through the web browser, or installs the presentation application provided by the analysis server 6 and displays the analysis screen by the presentation application.

[0019] In addition, the organizer device 2 accepts the input, editing, and registration of lecture information regarding the lecture meeting (for example, lecture meeting identification information (ID), lecture meeting title, lecture meeting date, lecture meeting distribution time, total lecture meeting distribution time, lecture meeting summary (for example, field, released product, keyword), lecture meeting chairperson, lecturer, distribution options such as evaluation buttons, lecture meeting guidance media, lecture target, etc.), and transmits the input lecture meeting information to the distribution server 4 via the network 7 for registration. The organizer device 2 accepts the input, editing, and registration of lecturer information (for example, lecturer identification information (ID), lecturer name, lecturer affiliation, lecturer title, etc.) regarding the lecturer who conducts the lecture meeting for which the lecture meeting information has been registered, and transmits the input lecturer information to the distribution server 4 via the network 7 for registration.

[0020] The lecturer device 3 is a device held by the lecturer who conducts a predetermined lecture meeting, and is composed of, for example, a personal computer, a smartphone, a tablet terminal, etc. The lecturer device 3 is equipped with a camera and a microphone, creates lecture meeting data obtained by photographing and sound collecting the lecture meeting of the lecturer, and transmits it to the distribution server 4 via the network 7. For example, the lecturer device 3 creates lecture meeting data by using, as a lecture meeting tool, a tool for executing online communication corresponding to the online communication service used in the distribution server 4, and transmits it to the distribution server 4. The lecturer device 3 may be equipped with applications such as Zoom (registered trademark) and Microsoft Teams (registered trademark) as lecture meeting tools. In addition, the lecturer device 3 may create lecture meeting data in association with the lecturer information.

[0021] The distribution server 4 is a device that operates a lecture distribution system that distributes lectures transmitted from the speaker device 3 to the viewer device 5. For example, the distribution server 4 uses online communication services such as Zoom® or Microsoft Teams® in the lecture distribution system to receive lecture data, which is recorded and sound-recorded from the lecture device 3, via the network 7, and distributes (transmits) it to the viewer device 5 via the network 7. The distribution server 4 stores the received lecture data in the database 8 and may distribute the lecture data via live streaming in real time, or it may distribute it on demand in response to requests from the viewer device 5.

[0022] Furthermore, the distribution server 4 may accept playback actions (interactions) such as playback, pause, seek, and exit operations on the viewing screen for viewing the lecture on the viewer device 5, and may also accept evaluation actions (interactions) such as electronic bulletin boards (BBS), surveys, and evaluation buttons.

[0023] Furthermore, the distribution server 4 stores lecture information relating to a predetermined lecture in the database 8, and also stores speaker information relating to the speaker giving the lecture, as well as lecture data for the lecture, in the database 8 in association with the lecture information. The distribution server 4 may receive lecture information, speaker information, and lecture data from the speaker device 3, and may also accept input and editing of lecture information and speaker information.

[0024] Furthermore, the distribution server 4 stores and registers viewer information for each viewer watching the lecture (e.g., viewer identification information (ID), viewer name, viewer affiliation, viewer title, etc.) in the database 8. The viewer information may also include the relationship between each viewer and the lecture (e.g., information received about the lecture), and may include, for example, whether the viewer is a member of the lecture organizer's or speaker's owned media or paid media, or whether they received an email distribution promoting the lecture. The distribution server 4 may receive viewer information from the viewer device 5, and may also accept input and editing of viewer information. The distribution server 4 accepts logins from the viewer device 5 using the viewer ID from the viewer information, and distributes (sends) the lecture data to the logged-in viewer device 5.

[0025] The distribution server 4 acquires viewing data (e.g., number of viewers, number of members, number of emails sent, viewing time, number of targets, etc.) for each lecture being distributed, and stores it in the database 8 in association with the lecture information.

[0026] Specifically, the distribution server 4 obtains the number of viewer devices 5 that watched the lecture as the number of viewers, and may obtain the number of viewers for each scene of the lecture. The distribution server 4 obtains the number of viewers devices 5 (viewer information) that watched the lecture and are equivalent to members of owned media or paid media related to the lecture organizer or speaker as the number of members. The distribution server 4 obtains the number of viewers devices 5 (viewer information) that watched the lecture in response to an email advertisement for the lecture as the number of emails sent. The distribution server 4 obtains the viewing time as the viewing time, which is the time each viewer device 5 watched (played) the lecture relative to the total lecture time. The distribution server 4 obtains the number of viewers devices 5 (viewer information) that watched the lecture and are equivalent to the lecture target as the number of targets.

[0027] Furthermore, when the distribution server 4 is distributing a lecture to the viewer device 5, if it receives a playback action related to viewing the lecture from the viewer device 5, it stores action information indicating the playback action in the database 8, associating it with the viewing data of the lecture. The distribution server 4 also accepts evaluation actions for a given lecture via electronic bulletin boards (BBS), questionnaires, evaluation buttons, etc., and stores action information indicating the evaluation action in the database 8, associating it with the viewing data of the lecture.

[0028] Viewer device 5 is a device owned by a viewer who is watching a designated lecture, and consists of, for example, a personal computer, smartphone, or tablet device. Viewer device 5 is configured to receive lecture data from the distribution server 4 via the network 7 in order to watch the designated lecture, and to display it on a display or output audio to a speaker or the like. For example, viewer device 5 receives and displays / outputs lecture data by using a tool for performing online communication as a lecture tool, corresponding to the online communication service used by the distribution server 4. Viewer device 5 may be equipped with applications such as Zoom® or Microsoft Teams® as a lecture tool. Viewer device 5 may also be equipped with a camera and microphone to take pictures and collect sound from the viewer and transmit them to the distribution server 4 via the lecture tool.

[0029] The viewer device 5 can accept input, editing, and registration of viewer information, and can register the entered viewer information with the distribution server 4. Furthermore, by logging into the distribution server 4 using the viewer ID registered with the distribution server 4, the viewer device 5 can attend lectures distributed by the distribution server 4 and receive lecture data from the distribution server 4. The viewer device 5 also uses a lecture tool to display the lecture viewing screen via an application or web browser. For example, the viewer device 5 accepts playback actions such as play, pause, seek, and exit on the viewing screen, and also accepts evaluation actions via electronic bulletin boards (BBS), surveys, and evaluation buttons.

[0030] The analysis server 6 is a lecture analysis device that operates a lecture analysis system 1, which acquires viewing data related to viewing by viewer devices 5 for each lecture that can be distributed by the distribution server 4, and analyzes the lecture based on the viewing data. The analysis server 6 accepts logins from organizer devices 2 using the organizer ID in the organizer information, and presents the lecture analysis results to the logged-in organizer device 2. The analysis server 6 creates an analysis screen that presents the lecture analysis results, and presents it to the organizer device 2 via a web browser that displays the analysis screen, or displays the analysis screen and presents it to the organizer device 2 via a presentation application installed on the organizer device 2.

[0031] The analysis server 6 is configured, for example, with a control unit 20, a storage unit 21, and a communication unit 22. The control unit 20 is a computer such as a CPU that comprehensively controls the overall operation of the analysis server 6 and is connected to the storage unit 21 and the communication unit 22. The storage unit 21 is composed of a recording medium such as ROM, RAM, or a hard disk drive, and stores programs and data for controlling the various components and functions of the analysis server 6. The communication unit 22 is an interface for the analysis server 6 to connect to a network 7 such as the Internet, that is, it connects the analysis server 6 to the organizer device 2 via the network 7.

[0032] The control unit 20 operates as a score calculation unit 25, a lecture analysis unit 26, an action statistics unit 27, and a display control unit 28 by executing a program stored in the memory unit 21. When the control unit 20 performs an analysis of a predetermined lecture, the score calculation unit 25, the lecture analysis unit 26, and the action statistics unit 27 perform the analysis, and the display control unit 28 displays the lecture list screen 30, etc., as an analysis screen to present the analysis results. At this time, the display control unit 28 operates as a score presentation unit, an analysis result presentation unit, and a statistics result presentation unit, and displays the score calculation result by the score calculation unit 25, the lecture analysis result by the lecture analysis unit 26, and the action statistics result by the action statistics unit 27 on the analysis screen.

[0033] The score calculation unit 25 acquires viewing data from the database 8 regarding viewing at each viewing device 5 of a predetermined lecture. The score calculation unit 25 also defines multiple types of evaluation axes for evaluating the lecture and sets a baseline value in advance for each evaluation axis. The score calculation unit 25 then calculates the evaluation value for each evaluation axis based on the acquired viewing data, and further scores the degree of the evaluation value relative to the baseline value within a range of multiple levels to calculate the evaluation score. The number of levels for the evaluation score of each evaluation axis is set to be the same. In addition, the score calculation unit 25 may add a weighting coefficient to calculate the evaluation value of the corresponding evaluation axis if it is determined that there is a high priority, for example, if the product, speaker, or audience is important or influential, by referring to the lecture information, speaker information, and viewing data.

[0034] For example, the score calculation unit 25 defines "number of viewers," which indicates the total number of people who watched the lecture, as an evaluation axis. The score calculation unit 25 then calculates an evaluation value and evaluation score for "number of viewers" based on the number of viewers indicated by the viewing data.

[0035] The analysis server 6 pre-sets the expected number of members of the conference organizer's and speakers' owned media and paid media who will watch the conference. The score calculation unit 25 defines a "member reach rate" as an evaluation axis, which indicates how well the number of viewer devices 5 (number of members) who watched the conference met the expected number. The score calculation unit 25 then calculates an evaluation value for the "member reach rate" and an evaluation score based on the number of members of viewer devices 5 indicated by the viewing data and the expected number of members.

[0036] The analysis server 6 pre-sets the expected number of audience devices 5 that will watch the lecture, and the score calculation unit 25 defines "target reach rate" as an evaluation axis, which indicates how well the number of audience devices 5 that watched the lecture (number of targets) achieved the expected number. The score calculation unit 25 then calculates an evaluation value for the "target reach rate" and an evaluation score based on the number of targets indicated by the viewing data and the expected number of lecture targets.

[0037] The score calculation unit 25 defines "viewership rate" as an evaluation axis, which represents the ratio of the average viewing time (calculated by averaging the viewing time of each viewer device 5 that watched the lecture) to the total lecture time of the lecture. The score calculation unit 25 then calculates the average viewing time by averaging the viewing time of each viewer device 5 as shown in the viewing data, and calculates an evaluation value for the "viewership rate" and an evaluation score based on the average viewing time and the total lecture time of the lecture.

[0038] The score calculation unit 25 defines an "interaction rate" as an evaluation axis, which represents the percentage of viewer devices 5 that performed an interaction such as posting on an electronic bulletin board (BBS) or answering a questionnaire out of all viewer devices 5 that watched the lecture. The score calculation unit 25 then counts the number of viewer devices 5 that performed an evaluation action (such as posting on an electronic bulletin board (BBS) or answering a questionnaire) based on the action information in the viewing data (number of interactions), and calculates an evaluation value for the "interaction rate" and an evaluation score based on the count result and the number of viewers indicated in the viewing data.

[0039] The score calculation unit 25 defines an "average evaluation score" as an evaluation axis, which represents the average evaluation result obtained by averaging the scores given to the lecture by each viewer device 5 using evaluation buttons, etc., that viewed the lecture. The score calculation unit 25 then calculates the evaluation value of the "average evaluation score" and the evaluation score by averaging the scores given by each viewer device 5 using evaluation actions (evaluation buttons, etc.) based on the action information of the viewing data.

[0040] Furthermore, the score calculation unit 25 calculates the overall score of the lecture based on the evaluation scores of multiple evaluation axes. For example, it calculates the overall score of the lecture by summing the evaluation scores of each evaluation axis. The score calculation unit 25 not only shows the overall score as the sum of each evaluation score, but also indicates which of the multiple levels (for example, five levels from A to E) the sum falls into when the range from 0 to perfect is divided into multiple levels.

[0041] The lecture analysis unit 26 selects two or more lectures from among multiple lectures registered in the database 8 according to a predetermined selection operation, and analyzes the evaluation scores and overall scores of multiple evaluation axes for each selected lecture. Alternatively, the lecture analysis unit 26 may narrow down the multiple lectures registered in the database 8 to those that meet predetermined filtering conditions, and select two or more lectures from the narrowed-down lectures. For example, the lecture analysis unit 26 may analyze the evaluation scores and overall scores of each evaluation axis for each selected lecture in ascending or descending order, or analyze them by comparing them with predetermined thresholds.

[0042] The lecture analysis unit 26 accepts settings for filtering conditions such as the period to which the lecture date and time belong, the products presented at the lecture, the range of the overall score of the lecture, keywords of the lecture content, distribution options, and announcement media. For example, if the lecture is related to the pharmaceutical and medical industry, the lecture analysis unit 26 may allow filtering conditions such as drug products, medical products, disease areas, and specialized fields.

[0043] The Action Statistics Unit 27 statistically processes action information from each viewer device when viewing a given lecture, based on viewing data acquired for that lecture. Here, the Action Statistics Unit 27 statistically analyzes playback actions such as playback, pause, seek, and exit by each viewer device 5 for each scene of the lecture, based on the action information from the viewing data. The Action Statistics Unit 27 also statistically analyzes evaluation actions such as using the electronic bulletin board (BBS), questionnaires, and rating buttons by each viewer device 5 for each scene of the lecture, based on the action information from the viewing data. The Action Statistics Unit 27 creates and associates thumbnails of the lecture data corresponding to each scene, along with the statistical results of playback and evaluation actions for each scene.

[0044] The display control unit 28 creates an analysis screen that displays the analysis results of the lecture by the score calculation unit 25, the lecture analysis unit 26, and the action statistics unit 27, and presents it to the organizer's device 2 via a web browser or presentation application.

[0045] The display control unit 28, for example, as an analysis screen, creates a lecture list screen 30 that displays a list of multiple lectures based on the lecture information, lecture data, viewing data, etc., of each lecture registered in the database 8, as shown in Figure 2, and presents it to the organizer device 2. The lecture list screen 30 displays, for example, a lecture filtering unit 31, an average evaluation display unit 32, and a lecture list unit 33.

[0046] The conference filtering unit 31 sets filtering conditions to narrow down the number of conferences to be displayed in the conference list unit 33 from among the multiple conferences registered in the database 8. For example, the conference filtering unit 31 accepts settings such as the period to which the conference date and time belong, the field of the conference, the products to be presented at the conference, the range of the conference's overall score, and keywords related to the conference content as filtering conditions.

[0047] The average rating display unit 32 displays the average rating of the lectures that have been filtered according to the filtering conditions set in the lecture filtering unit 31. For example, the average rating display unit 32 displays the average score obtained by averaging the overall scores of the filtered lectures, the total number of broadcasts, the total number of viewers, and the percentage of viewing time.

[0048] The lecture list section 33 displays a list of lectures that have been filtered according to the filtering conditions set in the lecture filtering section 31. Each lecture entry in the lecture list section 33 displays lecture information, such as lecture ID, lecture date, lecture delivery time, lecture title, total lecture delivery time, lecture field, presented products, overall score, number of viewers, announcement medium, and keywords. In addition, each lecture entry in the lecture list section 33 displays a selection operation section 34, such as checkboxes, which can be used to select lectures to be compared and analyzed. The selection operation section 34 allows the user to select one or more lectures from the lectures listed in the lecture list section 33.

[0049] The display control unit 28 allows users to select any one of the lectures in the lecture list unit 33 by clicking or other means. In response to the selection of a lecture, the display control unit 28 creates a lecture analysis results screen 40 that displays the analysis results for that lecture individually, as shown in Figures 3 to 7, and presents it to the organizer device 2 in place of the lecture list screen 30. The lecture analysis results screen 40 displays, for example, the overall evaluation unit 41 and the analysis results display unit 42.

[0050] The overall evaluation unit 41 displays the overall score of the lecture in a comparable manner to the industry average score of the field to which the lecture belongs.

[0051] The analysis results display unit 42 displays the basic information display unit 43, the viewing graph display unit 44, and the viewer list display unit 45 in a switchable manner according to the selection operation of tabs, etc.

[0052] As shown in Figure 3, when the basic information display unit 43 is displayed, the analysis result display unit 42 displays, for example, the date of the lecture, the lecture delivery time, the lecture title, the total lecture delivery time, the lecture field (e.g., disease area, medical field, etc.), the products presented, the lecture chairperson, the speaker, the delivery options, keywords, whether or not a video thumbnail is available, the number of viewers, the announcement medium, the viewing results, etc. Here, the viewing results indicate the number of devices of each type and the number of devices of each type of viewing bandwidth for each viewer device 5 that viewed the lecture.

[0053] As shown in Figures 4 to 6, when the viewing graph display unit 44 is displayed, the analysis result display unit 42 displays, for example, a viewing graph 46 with the distribution time on the horizontal axis, and the viewing graph 46 displays a viewer count graph 47, an evaluation action graph 48, and a playback action graph 49 in a switchable manner.

[0054] As shown in Figure 4, when the viewer count graph 47 is displayed in the viewer count display unit 44, the number of simultaneous viewers is plotted as a line graph for each time period, which is divided into predetermined intervals during the distribution time, and the number of viewers who started watching and the number of viewers who dropped out are displayed as bar graphs for identification. In addition, the viewer count graph 47 allows the display and hiding of the bar graphs for viewers who started watching and viewers who dropped out to be switched on and off. Furthermore, in the viewer count graph 47, it is possible to select each time period cell, and according to the time period selection, time-specific viewing data such as the number of simultaneous viewers, viewers who started watching, viewers who dropped out, and thumbnails for that time period are highlighted in a pop-up or the like.

[0055] As shown in Figure 5, when the evaluation action graph 48 is displayed in the viewing graph display unit 44, the number of simultaneous viewers is plotted as a line graph for each time period, which is divided into predetermined intervals of distribution time. In addition, the total number of evaluation actions, such as the number of electronic bulletin board (BBS) posts, the number of survey responses, and the number of evaluation button operations by each viewer device 5, is displayed as a single bar graph, and each bar graph displays the number of actions so that they can be identified. The evaluation action graph 48 allows switching the display on and off of the bar graphs for each action. Furthermore, the evaluation action graph 48 allows selection of each time period, and according to the time period selection, time-specific viewing data such as the number of BBS posts, the number of survey responses, the number of evaluation button operations, and thumbnails for that time period are highlighted in a pop-up or the like.

[0056] As shown in Figure 6, when the playback action graph 49 is displayed in the viewing graph display unit 44, the number of simultaneous viewers is plotted as a line graph for each time period, which is divided into predetermined intervals of distribution time. In addition, the total number of playback actions, such as the number of pause operations and seek operations performed by each viewer device 5, is displayed as a single bar graph, and each bar graph displays the number of actions in an identifiable manner. The playback action graph 49 allows the display and hiding of the bar graphs for each action to be switched on and off.

[0062] The overall score comparison unit 61 displays the overall scores of one or more selected lectures selected by the selection operation unit 34 of the lecture list unit 33 in parallel for comparison.

[0063] The simultaneous viewer comparison unit 62 displays a graph with the broadcast time on the horizontal axis, and for each time period in which the broadcast time is divided into predetermined intervals, it displays line graphs plotted to show the number of simultaneous viewers for one or more selected lectures in a comparable manner.

[0064] The viewer count comparison unit 63 displays bar graphs showing the number of simultaneous viewers for one or more selected lectures in parallel for easy comparison.

[0065] The interaction count comparison unit 64 displays, in parallel and for comparison purposes, a bar graph showing the total number of evaluation actions, such as the number of electronic bulletin board (BBS) posts, the number of questionnaire responses, and the number of times the evaluation button was pressed, for each of the one or more selected lectures' viewer devices 5. Each bar graph displays the number of each action in an identifiable manner.

[0066] The target reach rate comparison unit 65 displays bar graphs showing the target reach rate of one or more selected lectures in parallel for comparison.

[0067] The evaluation score comparison unit 66 displays radar charts showing the evaluation scores for each evaluation axis of one or more selected lectures, overlaid on each other, for comparative purposes.

[0068] The completion rate comparison unit 67 displays the completion rate numbers for one or more selected lectures side by side for comparison.
