Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

A method of posting a response to a questionnaire according to the present invention and a questionnaire service server supporting the method can be widely used for on / offline education, discussion, and lecture. That is, the 'questionnaire' described in the present specification means a person who receives a questionnaire issued by an instructor or a discussion host, as a participant or a debater participant in the on / offline education, discussion, or lecture.

Hereinafter, the present invention will be described with reference to embodiments of the present invention.

1 is a flowchart of a seminar progress support method to which the present invention is applied. As shown in FIG. 1, when the seminar starts (S10), the seminar data is displayed on the main display or the like installed in the seminar room (S20). The seminar material may be various types of presentation materials. One of the seminar processes can be a questionnaire about a student (S30). In FIG. 1, the questionnaire is shown as proceeding after the seminar data is posted. However, in the case of a seminar aiming at communicating with the student taking the questionnaire mainly, the seminar may be conducted mainly by the questionnaire without posting the seminar data.

When the present invention is utilized in an offline education, discussion, or lecture, the main display may be a seminar main display installed in a seminar room. When the present invention is utilized in an online education, discussion or lecture, the main display may be a participant of an education, a discussion or a lecture, that is, a lecturer and students, or a terminal of a discussion facilitator and a panelist. When the present invention is applied to an online education, discussion, or lecture, the questionnaire service server can provide data related to the screen to be displayed on the terminals of the instructor and the learners to the instructor and students of the learners. Hereinafter, embodiments of the present invention will be described on the assumption that the present invention is applied to an offline education, discussion, or lecture. However, the present invention can be applied to the case where the present invention is applied to an offline education, discussion, or lecture.

In the questionnaire proceeding (S30) according to the present invention, the communication between the lecturer and the lecturer regarding one questionnaire is not finished in one response. Instead, it can support a series of surveys and responses, helping instructors and students to interact with each other in a tail-worn manner.

For example, when the initial questionnaire of the multiple choice type and the responses of the students to the questionnaire are made, a first questionnaire asking why the fingerprint was automatically selected can be performed. If the response text for the first questionnaire is performed, the received response text may be posted on the main display of the seminar so that instructors and questionnaires can share opinions of the questionnaires. Next, a second questionnaire may be conducted asking whether or not the answer text of the specific student is related to the answer. The number of affirmative or negative votes for the second questionnaire may also be posted on the main display of the seminar so that the opinion of the questionnaires about the specific response text may also be shared.

When the questionnaire process (S30) is completed, a questionnaire survey may be performed in which the questionnaire that has been performed in the beginning is once again performed (S40). Results of the initial questionnaire and summary questionnaire results can be posted on the seminar main display (S50). Through this, we will be able to understand how the opinion of the questionnaires changed before and after the seminar.

Embodiments of the present invention relate to a method, apparatus, and system for supporting seminar progression in the form shown in FIG. Hereinafter, embodiments of the present invention will be described with reference to Figs.

Referring to the flowcharts shown in FIGS. 2 to 4, a method for posting a questionnaire opinion according to an embodiment of the present invention will be described. FIGS. 2 to 4 show a method of extracting a keyword from a received response text for a questionnaire of a questionnaire form, accumulating the keywords, and publishing a keyword cloud generated using the accumulated keyword together with the received response text list An embodiment is described.

First, a description will be made with reference to FIG.

The question content is posted on the main display of the seminar and transmitted to the questionnaire terminal (S300). The questionnaire contents may include questionnaires in the form of a questionnaire. The questionnaire terminal may be a student terminal installed in a seminar room or a mobile terminal of a student attending to a seminar room. In order to transmit the questionnaire contents to the mobile terminals of the attendees, it may be necessary to register the mobile terminals of the attendants in advance. The registering procedure may mean, for example, a procedure for installing a questionnaire application in the mobile terminal of the attendance person and selecting a seminar currently in progress through the attendee application.

If a response text for the question content is received from the questionnaire terminal (S310), the response text received in response to the response text may be listed up in real time on the main display of the seminar (S320). Although the flowcharts shown in FIGS. 2 through 4 show that the response texts are all displayed in real-time as they are received, according to another embodiment of the present invention, when the response texts are received, they are temporarily buffered After accumulating the response text, it may be listed up at a time when predetermined requirements are satisfied.

The response text may be understood to include a string.

According to one embodiment, the noise response determined to be meaningless in the response text may be filtered. That is, the noise response may be automatically excluded from the list-up object. However, a noise response that can be recovered through a well-known defect repair method such as auto / zero automatic conversion may be listed up after healing.

In the received response text, keywords may be extracted. Since the keyword is used to implicitly express the intention of the questionnaires, the part-of-speech can be selected mainly for the noun. Various methods can be used for the keyword extraction. For example, a method of selecting a word included in the keyword dictionary as a keyword among the words included in the response text using a keyword dictionary including keyword prediction words can be used.

On the other hand, a plurality of nouns included in one response text may be included in the keyword dictionary. In this case, the keyword can be selected in consideration of the position of the word.

According to one embodiment, only one keyword may be extracted in one response text, but according to another embodiment, a plurality of keywords may be allowed to be extracted in one response text with the pre-designated number as an upper limit.

The method of extracting the keyword from the received response text is not limited to the method described above, and various methods well known to those skilled in the art can be applied.

The keywords extracted from the response text may be accumulated in the keyword list as response texts are received (S340). In addition, the list of keywords included in the keyword list may be configured as a keyword cloud (S350). The keyword cloud is arranged to place the keywords at different positions so that the keywords can be visually recognized easily.

According to an embodiment of the present invention, the number of extraction of each keyword may be further included in the keyword list. The number of extraction of each keyword can be used to generate keyword cloud.

According to an embodiment of the present invention, a keyword cloud of a 2D method may be generated by disposing the keywords so as to be scattered on a plane, or textures may be formed by texturing the keywords to be scattered on the surface of a virtual transparent stereoscopic screen according to another embodiment, You can also create a keyword cloud. When generating the keyword cloud of the 3D method, a user interface for allowing the transparent stereoscopic screen to be rotated by a user operation may be provided.

According to an embodiment of the present invention, the keyword cloud may be generated by reflecting the number of keyword extraction times included in the keyword list. In this case, the keyword cloud may be generated so as to be highlighted in the keyword cloud as the keyword extraction frequency is large. For example, the keyword cloud may be generated so as to be more emphasized than the other keywords through a font size, a font type, a font color, a font effect, and the like, as the keyword extraction frequency is large.

According to an embodiment of the present invention, the response text is posted to the seminar main display in real time as the response text is newly received, and the updated keyword cloud reflecting the received response text is also displayed in real time on the seminar main display Can be posted.

Meanwhile, according to another embodiment of the present invention, when the keyword cloud update command is input as shown in FIG. 3, keyword cloud updating and publishing can be performed manually (S342, S350, S352). At this time, the keyword cloud update button may be displayed together with the keyword cloud in the main display of the seminar.

Meanwhile, according to another embodiment of the present invention, when the keyword cloud update condition is completed as shown in FIG. 4, the keyword cloud may be automatically updated. For example, only the reception of the response text and keyword accumulation are performed until a predetermined number of response texts are received (S344), and the keyword cloud update and posting (S352) is performed after a predetermined number of response texts are received . For example, it is possible to set the "pre-designated number" to automatically update the keyword cloud when a response text is received by the number of questioned letters, or a response text corresponding to a certain percentage (e.g., 20% Quot; predetermined number "so that the keyword cloud is automatically updated every time the keyword cloud is updated.

The reception of the response text, the list-up, the keyword extraction, and the keyword cloud update and publishing operations are repeated until the questionnaire response ends (S370).

With reference to FIGS. 2 to 4, a keyword cloud is extracted from the received response text for a questionnaire of the open-ended type, the keyword is accumulated, and the keyword cloud generated using the accumulated keyword is combined with the received response text list An embodiment of a method of publishing has been described. 2 to 4 are common in that the response text is listed in real time on the seminar main display, but they are different at the time when the keyword cloud is updated and posted. In FIG. 2, the keyword cloud is updated in real time. In FIG. 3, the keyword cloud is updated and published when the user's command exists. In FIG. 4, do. The present invention can be understood through the embodiments shown in FIGS. 2 to 4, but the update time of the keyword cloud and the display time of the updated keyword cloud are not limited to those described with reference to FIGS. The update time of the keyword cloud and the display publication time of the updated keyword cloud may be appropriately adjusted based on the number of students attending and the system performance of the questionnaire service server by the ordinary technician in the technical field of the present invention.

Referring to FIG. 5, an example in which a secondary questionnaire is conducted based on the response text of the questionnaires will be described. According to the present embodiment, the opinion of the other questionnaire on the response text of the questionnaire can be questioned. According to the present embodiment, a secondary survey progress button of each response text may be placed adjacent to each response text on the seminar main display.

For example, when a second survey progress button for the response text "X" is input (S380), a second survey content may be generated asking whether or not the answer text "X" The secondary questionnaire contents will be transmitted to the questionnaire terminal (S382). It is preferable that the learner terminal transmitting the response text "X " is excluded from the reception target of the secondary survey content.

According to another embodiment of the present invention, the secondary survey content for the response text "X" may be to ask for a deepening comment associated with the response text "X ". This second questionnaire content can be used to deepen the discussion by using the opinion of the specific lecturer.

The questionnaires who have received the secondary questionnaire content will receive the secondary questionnaire content and respond with one of "yes / no" (S384). The number of collected yes / no can be displayed adjacent to the response text "X ".

According to the present embodiment, there is an effect that it is possible for the instructor to easily grasp whether another student attends to a specific opinion of the student. According to the prior art, in order to confirm whether or not a student attended a presentation, another student attended to the presented opinion, he or she would have had to take other measures such as letting the other student take his hand. According to the example, each lecturer is free from the protection of anonymity, so that it is possible to freely express the opinion of the other lecturer.

It will be appreciated that at least some of the combinations of blocks and flowchart illustrations in the flowchart illustrations shown in FIGS. 2-5 may be performed by computer program instructions. These computer program instructions may be loaded into a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus, so that those instructions, which are executed through a processor of a computer or other programmable data processing apparatus, Thereby creating means for performing functions.
