  The interactive learning system 10 is a computer system that allows the learner 90 to learn by interacting with the learner 90.

  Referring to FIG. 1, the dialogue learning system 10 includes an information presenting unit 11, a dialogue control unit 13, a score calculation unit 14, a dialogue creation unit 15, and a storage unit 16. The information presentation unit 11, the dialog control unit 13, the score calculation unit 14, the dialog creation unit 15, and the storage unit 16 implement the functions of the dialog learning system 10. Each function realized by each unit will be described later. The information presentation unit 11, the interaction control unit 13, the score calculation unit 14, and the interaction creation unit 15 are realized by executing a software program by a processor as an example. The storage unit 16 is a memory that stores information necessary for executing a software program.

  Referring to FIG. 2, the interactive learning system 10 includes a server 20 and an information terminal 30 as hardware.

  The server 20 is a device that realizes main functions of the interactive learning system 10, and is a general computer as an example. The server 20 includes a processing device 21, a main memory 22, a storage device 23, a communication device 24, an input device 25, and a display device 26, which are connected to a bus 27.

  The storage device 23 is a device that stores data in a writable and readable manner. The storage unit 16 realizes the storage unit 16 illustrated in FIG. The processing device 21 is a processor that reads data stored in the storage device 23 into the main memory 22 and executes processing of a software program using the main memory 22. Each unit illustrated in FIG. 1 is realized by the processing device 21. The communication device 24 transmits information processed by the processing device 21 via a communication network including wired or wireless or both, and transmits information received via the communication network to the processing device 21. The received information is used by the processing device 21 for software processing. The input device 25 is a device such as a keyboard and a mouse that receives information from an operation input by an operator, and the input information is used by the processing device 21 for software processing. The display device 26 is a device that displays image and text information on a display screen in accordance with software processing by the processing device 21.

  The information terminal 30 is a device that accesses the server 20 and provides a service provided by the server 20 to a learner, and is, for example, a personal computer. The information terminal 30 includes a camera 31, a microphone 32, a speaker 33, and an information processing device. The information processing device 34 is a device that includes a processor, a memory, an input device, a display device, and a communication device (not shown) and executes a software program by the processor. The camera 31 can capture an image of the learner 90 in front of the information terminal 30. The microphone 32 can acquire the voice of the learner 90 in front of the information terminal 30. The speaker 33 can output sound to the learner 90.

  As illustrated in FIG. 3, the information terminal 30 processes a video captured by the camera 31 and a voice obtained by the microphone 32 in cooperation with the server 20 in a conversation with the learner 90, and displays the video on a display device. And the sound is output from the speaker 33. In the example of FIG. 3, an image of the avatar lecturer 99, which is a character simulating the lecturer, is displayed on the display device, and a voice simulating the voice of the avatar lecturer 99 is output from the speaker 33.

  Returning to FIG. 1, the storage unit 16 stores question information, which is information on a predetermined question sentence of a question to be set for the learner 90 and a plurality of correct answer phrases included in the correct answer of the question.

  FIG. 4 is a diagram illustrating an example of the problem information. In the question information 40, a question number, a question sentence, a correct answer, a correct constituent word and its attribute are registered for each question. The problem number is a number that uniquely identifies the problem. The question sentence is a text indicating a sentence that asks the learner 90 a question. The correct answer sentence is a text indicating an example of a correct answer to the question asked in the question sentence. The correct constituent phrase is one or more words included in the correct sentence. The question of question number Q001 in FIG. 4 has five correct constituent phrases. Correct answer phrases have attributes. The attribute indicates the nature of what the correct constituent word means in the correct sentence. The attributes include, for example, an attribute indicating “when”, an attribute indicating “where”, an attribute indicating “who”, an attribute indicating “why”, and an attribute indicating “what”.

  The information presenting unit 11 presents the learner 90 with presentation information on a problem. The presentation here means, for example, outputting video and audio so that the avatar lecturer 99 speaks toward the learner 90. In addition, the presentation information referred to here includes a question sentence of a question asking the learner 90, a hint for encouraging the learner 90 to ponder, and a correct answer sentence for notifying the learner 90 of the correct answer. Details of the presentation information will be described later.

  The response acquisition unit 12 acquires response information on a response to a problem by the learner 90. The acquisition here means, for example, converting the speech uttered by the learner 90 to the avatar lecturer 99 into text.

  The dialogue control unit 13 realizes a dialogue with the learner 90 by controlling the association between the response information and the presentation information. The dialogue control unit 13 presents the question sentence of the question as first presentation information to the learner via the information presentation unit 11 based on the question information. Further, the dialogue control unit 13 acquires first response information relating to the response of the learner 90 acquired via the response acquisition unit 12, and analyzes the first response information. If the first response information includes a predetermined threshold or more among all the correct constituent words registered in the question information 40, the dialog control unit 13 determines that the learner 90 has answered the correct answer. In the present embodiment, if all the correct constituent words registered in the question information 40 are included in the first response information, it is determined that the learner 90 has answered the correct answer. If the first response information does not include at least one of the correct constituent words registered in the question information 40, the interaction control unit 13 determines that the learner's response is insufficient. Then, the dialogue control unit 13 presents the information on the correct constituent words not included in the first response information to the learner 90 via the information presenting unit 11 as the second presentation information. Since the learner 90 does not always utter all the responses without interruption, the first response information is not always united. The first response information may be a plurality of text groups. The second presentation information is, for example, a hint or a model answer. Presenting a part of the correct constituent words not included in the first response information is a hint to the learner 90. Presenting all the correct constituent words not included in the first response information presents the correct answer to the learner 90 and prompts the learner 90 to remember it. For example, the correct sentence itself may be presented.

  As described above, according to the present embodiment, a problem sentence of a problem in which a correct answer includes a plurality of correct constituent words is presented to the learner 90, a response from the learner 90 is obtained, and the learner 90 Since the correct constituent words that are not included are presented to the learner 90, the learner 90 can be provided with an opportunity to ponder to remember the correct answer through dialogue, thereby enabling effective learning.

  The score calculation unit 14 calculates a score for each problem for each learner 90 based on the first response information. Thereby, since the answer of the learner 90 is made into a score, the degree of understanding of the learner 90 can be quantitatively evaluated. When the dialogue control unit 13 presents a hint to the learner 90, a score is calculated from the first response information to which the learner 90 has responded before the hint is presented. For example, the understanding level of each subject of the learner 90 may be calculated based on a total value (for example, a total value or an average value) obtained by totaling the scores of the questions included in each subject.

  The dialog creating unit 15 analyzes a predetermined correct answer sentence for the question and specifies a location that can be a correct constituent word. For example, when an operator gives a correct sentence to a question, a portion that can be a correct constituent phrase is specified from the correct sentence, so that the operator can select a correct constituent phrase from the specified portion. The operator can easily create a scenario of the dialogue with the learner 90 regarding the problem.

  Hereinafter, the operation of the interactive learning system 10 will be described in more detail.

  FIG. 5 is a flowchart of a dialogue learning process executed by the dialogue learning system.

  The dialogue control unit 13 acquires the question sentence of the question to be set from the question information 40 and presents it to the learner 90 via the information presenting unit 11 (step S101). Next, the dialogue control unit 13 executes a response acquisition process (Step S102). The response acquisition process is a process of acquiring a response from the learner 90. Details of the response acquisition process will be described later.

  Next, the dialog control unit 13 determines whether or not the correct answer has been completed based on the response from the learner 90 (step S103). If all the correct constituent words registered for the question set in the question information 40 are included in the response, it is determined that the correct answer is completed. Otherwise, it is determined that the correct answer is not completed.

  If the correct answer is completed, the dialog control unit 13 executes a score calculation process (step S106). Further, the dialog control unit 13 presents the correct answer to the learner 90 (step S107). This shows a model answer example to the learner 90 who has given a correct answer, and promotes the organization of understanding and the like. Further, the dialogue control unit 13 presents the evaluation result to the learner 90 based on the score (Step S108). As the evaluation result, the score itself may be presented to the learner 90, or a comment corresponding to the score may be presented to the learner 90. If the score is good, information such as "I understand well. I am correct" may be presented.

  On the other hand, if the answer is not completed in step S103, the dialog control unit 13 determines whether or not the response from the learner 90 has timed out (step S104). Specifically, the dialog control unit 13 determines whether or not the elapsed time from the presentation of the question sentence exceeds a predetermined threshold (rear threshold time). If the elapsed time exceeds the backward threshold time, it is time-out. A fixed time such as one minute may be set as the rear threshold time, or a different time may be set depending on the problem. If the response from the learner 90 has timed out, the dialog control unit 13 proceeds to step S106.

  If the response from the learner 90 has not timed out, the interaction control unit 13 executes a hint presentation process (step S105). The hint presentation process is a process of presenting information (hints) to the learner 90 as clues for completing a correct answer. When the learner 90 has not completed a correct answer, that is, when all correct constituent words have not been listed, the learner 90 can be encouraged to give a correct answer. Details of the hint presentation processing will be described later. After performing the hint presenting process, the dialog control unit 13 returns to step S102.

  FIG. 6 is a flowchart of the response acquisition process.

  In the response acquisition processing, if the speech of the utterance by the learner 90 has been acquired (YES in step S201), the dialogue control unit 13 extracts the correct constituent words from the speech (step S202). If the correct constituent words are included in the voice of the learner 90, the dialog control unit 13 records the extracted dialog correct words and related information response information (step S203).

  FIG. 7 is a diagram illustrating an example of the response information. FIG. 7 shows an example of response information 50 that records the response of the learner 90 to one problem. The question has five correct constructs. The response information 50 can record the utterance information, the utterance rank, the utterance elapsed time, the hint presentation information, and the hint rank for each of the correct answer phrase numbers 1 to 5. The utterance information indicates whether the learner 90 has uttered the correct constituent phrase or, if so, whether it uttered before the first hint is presented or after the first hint. The utterance order indicates the order of the correct answer phrase among the correct answer phrases corresponding to the question. The utterance elapsed time indicates how much time has passed since the question sentence was presented until the correct constituent word was uttered. The hint presentation information indicates whether or not the correct constituent word has been presented to the learner 90 as a hint. The hint ranking indicates in what order the correct constituent word is presented as a hint.

  On the other hand, if the voice of the utterance by the learner 90 has not been acquired in step S201, the dialog control unit 13 has passed a predetermined time (blank threshold time) since the voice of the learner 90 was previously acquired. If it is (YES in step S204), the voice acquisition process ends as a timeout. If the blank threshold time has not elapsed since the last time the voice of the learner 90 was acquired (NO in step S204), the dialog control unit 13 returns to step S201.

  FIG. 8 is a flowchart of the hint presentation process.

  In the hint presentation processing, the dialogue control unit 13 acquires the response information 50 of the question currently being asked (step S301). Subsequently, the dialogue control unit 13 acquires a history of test results obtained when a problem currently presented to the learner 90 is previously presented to the learner 90 (step S302).

  FIG. 9 is a diagram illustrating an example of a test result. The test result is information in which the result of the response of the learner 90 for the question set is recorded.

  In the test result 60, the serial number, the question number, the question date and time, the score, and the response information are recorded for the questions that have been set. The serial number is a serial number assigned to the question that has been set. If the same question is asked multiple times, a different serial number is assigned to each. The question number is a number that identifies the question that was set. The question number of the test result 60 corresponds to the question number of the question information 40. When the same question is given a plurality of times, the same question number is recorded in the test result 60. The question date and time indicates the date and time when the question was set. The score indicates the score of the response of the learner 90. The response information records the response information 50 when the score is finally calculated. Therefore, the response information included in the test result 60 includes the utterance, the utterance rank, the utterance elapsed time, the hint presentation, and the hint rank for each correct constituent phrase as in the response information 50 shown in FIG. Information is included.

  Next, the dialogue control unit 13 selects any one of the correct constituent words not included in the response information and determines it as a hint (step S303). At that time, the dialogue control unit 13 selects a correct constituent word to be used as a hint in consideration of the response information 50 when the question was asked in the past. For example, a correct constituent word that was not used as a hint when the same question was previously given may be selected as a correct constituent word that is preferentially used as a hint. Alternatively, the order of hints may be determined in advance for a plurality of correct constituent words corresponding to the question, and the correct constituent words to be hints may be selected according to the order. Alternatively, correct constituent words to be used as hints may be selected in accordance with the order in which they appear in the correct sentences corresponding to the questions.

  Then, the dialogue control unit 13 presents a hint sentence based on the correct constituent word selected as a hint to the learner 90 (step S304). At that time, the correct constituent word itself may be included in the hint sentence. For example, a hint sentence "It is related to aaa (correct constituent word)" may be presented. Alternatively, a question sentence asking a word corresponding to the attribute of the correct answer word may be used as the hint sentence. For example, if the attribute of the correct constituent word selected as a hint indicates “when”, a question sentence “when did this happen?” May be used as the hint sentence.

  Then, the dialogue control unit 13 records the hint presentation and the hint order information in the response information 50 of the question being set (step S305).

  Note that the hint presentation process shown here is executed when the elapsed time without presenting the correct answer phrase as a response from the learner 90 reaches a predetermined response time threshold after presenting the question sentence. Is also good. The response time threshold may be adjusted to an appropriate value. For example, a time such as 10 seconds may be set as the response time threshold.

  FIG. 10 is a flowchart of the score calculation process.

In the present embodiment, the score is calculated according to equation (1).
Score = S1 + S2 (1)
In the equation (1), S1 = (the number of correct constituent words responded within the backward threshold time before the hint presentation after the question sentence) / (total number of correct constituent words) × 80. Further, in the equation (1), S2 is determined as follows: all the correct constituent words are answered within a backward threshold time before the hint is presented after the question is presented, and a predetermined time is determined before the hint is presented after the question is presented. Is 20 if the first correct constituent word is answered within the forward threshold time of, and 0 otherwise.

  In the score calculation process of FIG. 10, the dialogue control unit 13 counts the number of correct constituent phrases spoken by the learner 90 before giving the first hint (step S401). Subsequently, the dialogue control unit 13 calculates the score S1 based on the counted number of correct constituent words (step S402).

  Next, the dialog control unit 13 determines whether or not the correct answer has been completed (step S403). Specifically, it is determined whether or not all the correct constituent words have been listed. If all the correct constituent words have been listed, the dialogue control unit 13 determines that the first correct constituent word has been set before the predetermined threshold time (forward threshold time) has elapsed since the question sentence was presented. It is determined whether it has been raised (step S404). If the first correct constituent word is listed before the forward threshold time elapses after the question sentence is presented, the dialogue control unit 13 calculates the score S2 (step S405). Subsequently, the dialog control unit 13 records the score = S1 + S2 in the test result 60 (Step S406).

  If all correct constituent words have not been listed in step S403, or if the correct constituent words listed first in step S404 have not been listed before the forward threshold time has elapsed since the question sentence was presented, The dialog control unit 13 records the score = S1 in the test result 60 in step S406.

  FIG. 11 is a sequence diagram illustrating a state of the interactive learning. Assume that the question sentence is "Can you explain the changes in Honnoji?" The correct answer is "The incident was that" Mitsuhide Akechi "" attacked "Nobunaga Oda in" Honnoji "on June 21, 1582." In this correct sentence, it is assumed that "June 21, 1582", "Honno-ji", "Mitsuhide Akechi", "Nobunaga Oda", and "attack" are correct answer phrases.

  First, the avatar lecturer 99 of the interactive learning system 10 asks the learner 90 the question, "Can you explain the changes in Honnoji?" In response to that question, the learner 90 replied, "Em, at" Honnoji, ... ". Therefore, the avatar lecturer 99 gives a hint to the learner 90 that "Akechi Mitsuhide is relevant." The learner 90 who heard the hint responded, "Ah, this is the case where Mitsuhide Akechi attacked Nobunaga Oda." In addition, since not all correct constituent words have been listed, the avatar instructor 99 further gives the learner 90 a hint, "When is that?" In this way, the avatar instructor 99 gives hints so that the learner 90 ponders on the problem, so that the problem and the correct answer are likely to remain in the memory of the learner 90.

  Note that, in the present embodiment, an example has been described in which the interactive learning system 10 acquires information by presenting information to the learner 90 with the video and audio of the avatar lecturer 99 and acquiring the utterance of the learner 90. It is not limited to this. The presentation of the information may be text display on a screen, output of a question sentence by voice, or the like. The information may be obtained by receiving an operation of the learner 90 such as a keyboard, a mouse, and a touch.

  Further, in the present embodiment, the case where the correct constituent words are uniquely determined is illustrated, but the present invention is not limited to this. If any of a plurality of words having the same meaning or similar meaning is valid as a correct constituent word, any of them may be listed. In addition, even if the meaning is different, any one of a plurality of correct phrases may be listed in the correct sentence. For example, in the example shown in FIG. 11, if a phrase such as "attacked", "killed", or "killed" is appropriate instead of the correct constituent word "attack", any of those phrases is appropriate. It may be good if it is raised.

  Further, in the present embodiment, when the interactive learning system 10 presents the question sentence to the learner 90 and then declares that the learner 90 cannot respond or declares to give up the answer, all the correct answer configurations are set. A phrase, for example, a correct sentence may be presented as it is. Further, in the present embodiment, after the interactive learning system 10 presents the question sentence to the learner 90, if the learner 90 requests a hint, the hint presenting process may be executed.
