Candidate client 100 is a plurality of terminal devices that are connected to a network and receive learning evaluation services such as online listening evaluation, and include all of desktop PCs, laptops, mobile phones, PDAs, and MBS (Mobile Broadcast System) phones. can do.

1 shows a web server 102, a broadcast server 104, a broadcast organization server 116, a test management server 106, and a time synchronization server 108 as servers constituting the learning evaluation service system. However, it will be apparent to those skilled in the art that the above server can be integrated into one or more servers as needed.

According to a preferred embodiment of the present invention, when the candidate client 100 accesses the web server 102, the web server 102 determines whether an application for learning evaluation is installed in the candidate client 100, If not installed, the learning evaluation application is transmitted to the candidate client 100.

In this case, the learning evaluation application may be installed in the form of ActiveX control. However, the learning evaluation application does not need to be installed, and the online learning evaluation service may be provided through a web browser without a separate application.

The test management server 106 according to the present invention performs a function of generating test information to be provided to the candidate according to a predetermined algorithm, and a question bank DB 110 for storing problem information and fingerprint information and a problem to be reproduced. Or it is connected to the streaming file server 112 for storing the fingerprint file in the streaming file format.

Here, the fingerprint file is a listening file which the candidate should listen to solve the problem, and is transmitted by streaming during the listening evaluation test.

8 is a diagram illustrating a field structure of a question bank DB according to an exemplary embodiment of the present invention. As shown in FIG. 8, the question bank DB 110 includes a course and subject information field 800 and problem information. Field 802 and fingerprint information field 804.

The course and subject information field 800 records level information such as beginner, intermediate, and advanced, and subject type information at each level.

The problem information field 802 includes a question question, a subject, a fingerprint 804, a dependent problem 806, a difficulty level, individual data 808, a problem type 810, a fingerprint time 812, a problem time 814, and a problem. The unique identifier is recorded.

Here, the fingerprint 804 refers to information about a file provided to the candidate by streaming. The fingerprint 804 may be an audio file or a video file, and as illustrated in FIG. 8, the fingerprint name of the fingerprint having a corresponding problem. And detailed information such as fingerprint type, playback time, and streaming file path.

The dependency problem 806 is information about a problem that depends on the problem, and the information about the dependency problem 806 may be included when the problem is an independently questionable question.

According to the present invention, a plurality of questions can be asked in one fingerprint, and each problem can be divided into independent and dependent problems, wherein the dependent problem is a problem that can be asked only when the independent problem is asked.

The problem type 810 means information for discriminating whether a problem type is a basic, that is, a text or image file or a streaming file, and in the case of a streaming file, it may be an audio or video file.

In general, in the listening evaluation test, not only the fingerprint but also the view of the problem may be provided in an audible form. In the viewing time 812 according to the present invention, when the view of the problem is transmitted by streaming, the playback time is recorded.

In problem time 814, the problem solving time determined according to the difficulty level or problem length of the problem is recorded. Here, the problem solving time may be the sum of the time taken to solve the problem when the problem view is provided as a streaming file, and when the problem view is listened to.

Meanwhile, the streaming file server 112 stores a file to be sent to streaming during fingerprinting, problem questioning, and problem viewing, and the format of the streaming file is ASF (Advanced Streaming File) used by Microsoft's Netshow. ) Or a RealMedia file used by Progressive Network, but is not necessarily limited thereto.

The test management server 106 according to the present invention randomly extracts problem information for a predetermined subject according to a difficulty level preset in the question bank DB 110.

According to the present invention, it is determined whether the problem solving time 814 and the fingerprint file playing time of a problem extracted so far exceed the predetermined test time for each problem information extraction process so that the extracted problem and the test time coincide. For example, if the test time is exceeded, another problem information is extracted instead of the previously extracted problem information.

In addition, according to the present invention, it is possible to consider the information 806 on whether there is a dependent problem in the problem information extraction process, through which it is possible to make more than one question for one fingerprint.

A problem number may be assigned to the extracted problem as described above, and identification information including the extracted problem information and the problem number may be included.

Meanwhile, the question or view of a problem belonging to one fingerprint may be a text, an image or a streaming file. According to one preferred embodiment of the present invention, the test management server 106 may include one or more fingerprints and a question belonging to each fingerprint. Alternatively, a process of grouping view information is performed to create a streaming file list.

The streaming file list according to the present invention may include fingerprint identification information, fingerprint path information, and identification information and path information about the streaming file of the question or view belonging to the fingerprint.

In the prior art, since a fingerprint file was provided for each test taker when generating listening evaluation test information, the question bank simply extracted a problem by considering only the number of problems or the difficulty level of each question. Although the matching process is not performed, the present invention performs the process of the test management server 106 determines whether the test timed out as described above, so that all candidates take the test for the same time under the same conditions. Allows multiple questions with the concept of independence / dependency on a single fingerprint.

On the other hand, the learning evaluation service according to the present invention broadcasts the test information at a predetermined time in order to allow all users to take the test for the same date and the same time as offline.

To this end, when the test management server 106 generates the test information and requests the broadcast scheduling server 116 to broadcast the broadcast scheduling server 116 receives the test information from the test management server to set the time zone to broadcast the test information. Decide

In addition, as described above, the test information includes a problem number and one or more problem information, and each problem information includes a reproduction time and a problem solving time of a fingerprint file, and the broadcast programming server 116 according to the present invention is broadcasted. The fingerprint file transfer time and problem solving time are used to determine the fingerprint file transfer time within the time range.

For example, the broadcast time zone is 10 to 10:30, the test consists of 10 fingerprints and 15 questions. The duration of the fingerprint file 1 is 1 minute, and the problem belongs to 2 fingerprints. When the pool time is 2 minutes, the broadcast scheduling server 116 determines the broadcast time of fingerprint 1 as 10 o'clock and the broadcast time of fingerprint 2 as 10: 3.

In this way, the broadcast time for the remaining fingerprints is determined.

On the other hand, as described above, the problem question or view may also be a streaming file, the broadcast organization server 116 according to the present invention uses the fingerprint file playback time and the preset time as the transmission time of the streaming file of the problem question or view Decide by

For example, if the fingerprint file playback time is 1 minute and the preset time is 3 seconds, the transmission time of the streaming file of the question or view is 1 minute 3 seconds, which is the sum of the fingerprint file playback time and the preset time in the fingerprint transmission time. If there is another problem preceding the question or view, the streaming file transfer time of the question or view may be determined by adding the fingerprint file playback time and the pooling time of the preceding problem plus the preset time. have.

The broadcast server 104 according to the present invention receives broadcast schedule information including a fingerprint file transmission time and transmits a fingerprint file at each fingerprint file transmission time within a preset broadcast time zone.

According to the present invention, if the problem (question and view) belonging to the fingerprint currently being reproduced is a text or an image, the broadcast programming server 116 determines the fingerprint transmission time as the problem output time, and the broadcast server 104 determines the fingerprint. At the same time as it starts broadcasting, it is preferable to transmit the problem information so that the candidate can check, but without being limited thereto, it may be possible to transmit the problem first before transmitting the fingerprint so that the problem can be identified first.

The time synchronization server 108 synchronizes the network time between the broadcast server 104 and the candidate client 100 so as to transmit fingerprints and problem files of the broadcast server 104 and receive the candidate client 100 at a time according to the broadcast scheduling information. Allow the process to be done at the same time.

In addition, when the test time is terminated by determining whether or not the test is terminated, a function of forcibly terminating the test in the candidate client 100 is performed.

Meanwhile, the broadcast server 104 may be configured as a distributed server to simultaneously transmit test information in various regions. At this time, the time synchronization server 108 may synchronize the time of each broadcast server to simultaneously broadcast. .

On the other hand, since the learning evaluation according to the present invention proceeds the same for all the candidates on the same date and the same time, the candidate who accesses the predetermined broadcast time completes the learning evaluation process due to an error of the broadcast server 104 and a network failure. In this case, the test management server 106 assigns a retest certification number to the abnormally terminated candidate.

Accordingly, when the candidate subsequently requests a retest, the learning evaluation application installed in the candidate client 100 accesses the web server 102 and transmits a retest certification number, and the broadcast server 104 separately configures a rebroadcast channel. Through the process of transmitting the test information to the candidate client 100 through.

At the end of the test, the candidate's problem solving result information is transmitted to the test management server 106, the test management server 106 performs a scoring process, and stores the test result in the test taker DB 114.

The test taker DB 114 stores not only the test result of the test taker but also test taker login information, test taker ID information, and a retest authentication number assigned to the test taker.

In the above description, the learning evaluation service according to the present invention has been described in the same manner for all test takers at a predetermined date and time as in the offline manner, but the present invention is not limited thereto, and the test taker accesses the web server 102 at a predetermined time to perform the learning evaluation. When requesting, the fingerprint file is transmitted to the candidate client 100 based on the transmission time based on the fingerprint file playback time and the problem solving time based on the candidate request reception time. It would also be possible.

In addition, in the above description, the broadcast server 104 transmits a fingerprint file according to predetermined broadcast programming information, that is, a predetermined fingerprint file transmission time. However, at the start of the test, the candidate client 100 transmits a fingerprint file. Receives and temporarily stores a fingerprint file without any information about it, and determines the playing time of the next fingerprint through test information including a fingerprint playing sequence, a fingerprint playing time, and a problem solving time that the learning evaluation application transmits from the broadcast server. It would be possible.

2 is a diagram showing a module configuration of a test management server according to an embodiment of the present invention.

As shown in FIG. 2, the test management server according to the present invention includes a problem and fingerprint management module 200, a problem information extraction module 202, a fingerprint grouping module 204, a test time check module 206, and a broadcast schedule. The request module 208, the candidate information management module 210, and the retest certification number providing module 212 may be included.

The problem and fingerprint management module 200 performs a process of storing and managing information on a problem and a fingerprint registered by a subject as a structure as shown in FIG. 8, and converts a file that a candidate must listen to among a problem and a fingerprint as a streaming file. The converted file is stored in the streaming file server 112.

The problem information extraction module 202 performs a process of randomly extracting problem information according to a predetermined difficulty level.

Here, the predetermined difficulty refers to the difficulty of the entire test, and may be divided into upper, middle, and lower, and individual problems are extracted according to the set difficulty. For example, when the total test difficulty is set to upper, problem information The extraction module 202 may extract only an individual problem having a difficulty level higher than that of the problem information 702 illustrated in FIG. 8, or extract a problem having an individual problem difficulty level at the highest ratio.

In addition, when there is a dependency problem for the extracted problem, the problem information extraction module 202 may selectively extract the dependent problem, thereby providing the candidate with two or more problems connected to each other in one fingerprint. It becomes possible.

Meanwhile, the problem information extracted by the problem information extraction module 202 may include fingerprint information and problem question or viewing information to be transmitted by streaming. The fingerprint grouping module 204 may include one fingerprint and a streaming file belonging to the fingerprint. Follow the process of grouping problem questions or views in the form.

Through the grouping process, a streaming file list of a plurality of fingerprints is created, and the streaming file list according to the present invention includes identification information of each fingerprint, fingerprint path information, and identification information and path information of streaming files of a question or view belonging to the fingerprint. May be included.

By using the streaming file list, the broadcast organization server 116 identifies the types of files to be transmitted by streaming, and determines the transmission time of each fingerprint file and the transmission time of a problem question or view.

The test time check module 206 performs a process of determining whether the extracted one or more problems fall within a predetermined test time range.

As described above, the learning evaluation service according to the present invention is preferably broadcasted on the same date and time. For this purpose, it is necessary to include problem information extracted within a predetermined time range.

As shown in FIG. 8, since the fingerprint file reproduction time and the problem solving time 714 are recorded in the problem information 702 according to the present invention, the test time check module 206 reproduces the fingerprint file of the problem extracted so far. Time and problem pooling time is summed, compared with the test time, and if the summed time exceeds the test time, the problem information extraction module 202 transmits a signal for problem replacement.

Accordingly, the problem information extraction module 202 extracts other problem information so as not to exceed the test time instead of previously extracted problem information.

According to an embodiment of the present invention, the test time check process may be performed in real time whenever problem information is extracted, but is not limited thereto, and after extracting a problem information of a predetermined number (for example, a predetermined number of problems for each subject) It will also be possible to sum the total problem solving time and the fingerprint file playback time and compare it with a predetermined test time.

When the extraction of the problem information and the test time check have been completed, the broadcast program request module 208 transmits test information including the problem information extracted to the broadcast program server 116 so that a fingerprint file or the like is streamed at a predetermined date and time. A request for transmission is performed, and the test information may include a streaming file list to facilitate streaming file identification.

By such a broadcast programming request, the broadcast programming server 116 determines a time zone for broadcasting a test, and determines a transmission time of each fingerprint file in the time zone.

The candidate information management module 210 stores the candidate's personal information, the test reception information, and the retest related information, receives and scores the problem solving result information transmitted by the candidate client 100, and stores the scoring result in the candidate DB. .

The retest certification number providing module 212 performs a process of providing a retest certification number to a corresponding candidate by receiving information indicating that the test process is abnormally terminated when a failure occurs during the test of the candidate and the broadcast is not performed.

The candidate can later reconnect to the web server 102 and send the retest authentication number to retest through the rebroadcast channel of the broadcast server 104.

3 is a diagram illustrating a module configuration of a broadcast programming server according to an exemplary embodiment of the present invention.

As shown in FIG. 3, the broadcast scheduling server according to the present invention uses the test information receiving module 300, the real time broadcast determining module 302, the broadcast time zone determining module 304, and the streaming file transmission time determining module 306. It may include.

The test information receiving module 300 receives test information generated by the test management server 106.

Here, the test information includes a plurality of extracted problem information, the number of each problem, information on whether or not it is a real-time broadcast request, the problem information includes the fingerprint and problem questions or viewing playback time, problem solving time and Contains the fingerprint and path information of the problem file.

According to the present invention, the test broadcast may be divided into a case of real time and a case of rebroadcast, and accordingly, time zones of the real time broadcast and rebroadcast are separately set.

Accordingly, the real-time broadcast determination module 302 according to the present invention determines whether the currently organized broadcast is a real time broadcast through the information included in the broadcast configuration request of the test management server 106, and determines the broadcast time zone module 304 ) Determines the broadcast time zone according to whether the broadcast is real time or rebroadcast.

When the broadcast time zone is determined, the streaming file transmission time determination module 306 performs a process of determining the transmission time of the fingerprint file and the question or view file which should be transmitted by streaming according to the problem solving time within the determined broadcast time zone range.

For example, if the broadcast time zone is determined to be 10 o'clock and 11 o'clock, the transmission time of each fingerprint file and the question or viewing file is determined between 10 o'clock and 11 o'clock in the order provided to each candidate.

As such, when the broadcast programming is completed, the broadcast programming server 116 transmits the broadcast programming information to the broadcast server 104, and the broadcast server 104 examines the problem file and the fingerprint file according to the broadcasting schedule at the predetermined time. Performs a process to transmit to (100).

4 is a flowchart illustrating a test information generation process in a preferred embodiment of the present invention.

Referring to FIG. 4, first, problem information is extracted from the problem bank DB 110 according to a predetermined difficulty level (S400). Here, the problem information is extracted randomly, and a plurality of problem information corresponding to a predetermined difficulty level is extracted.

The test management server 106 determines whether there is a dependency problem for the extracted problem (S402), and if there is a dependency problem, extracts the dependent problem information (S404).

As described above, there may be a question or view of an individual problem is an audio file or a video file, and the test management server 106 may include an individual problem question or view transmitted through fingerprint information and streaming included in each problem information. Information is set to one group (S406).

Through the group setting process, a streaming file list including a plurality of fingerprints and information about streaming files belonging to each fingerprint is created.

Thereafter, the test management server 106 adds the fingerprint file playing time and the problem solving time included in the problem information extracted so far (S408), and determines whether the summed time exceeds the predetermined test time (S410). ).

If the summed time exceeds the test time, the steps S400 to S410 are repeated so that the summed time is included in the test time range.

Test information generation is completed through the above process (S412), the test management server 106 requests the broadcast scheduling server 116 to organize the broadcast (S414).

5 is a flowchart illustrating a broadcast programming process according to an embodiment of the present invention.

Referring to FIG. 5, the broadcast programming server 116 receives broadcast programming request information from the test management server 106 (S500), and determines whether the broadcast programming request is a real-time broadcast programming request (S502).

When the broadcast programming request is a real time broadcast request, the broadcast scheduling server 116 determines a time zone set for real time broadcasting (S504), and in case of a rebroadcast request, determines a time zone set for rebroadcast (S506).

After determining the time zone, the broadcast scheduling server 116 extracts each fingerprint file playing time and each problem solving time information from the test information transmitted from the test management server 106 (S508), and extracts the fingerprint file playing time and the problem. The pool determines the transmission time of the fingerprint file using the time information (S510).

The determination of the fingerprint file transmission time refers to a process of determining when the broadcast server 104 transmits one or more fingerprint files to the candidate client 100 within the time zone determined above, and the step S510 is a streaming file. The list can also be used to determine the time of transmission of the question or view file for an individual problem.

Thereafter, the broadcast scheduling server 116 determines the output time of the question and the view information composed of text (S512). According to an exemplary embodiment of the present invention, the question information in question may be a transmission start time of the fingerprint having the problem. It may be set to output to, but is not limited to this, it is also possible to transmit the question of the entire problem in advance so that the candidate can check before the fingerprint playback.

6 is a flowchart illustrating a process of providing a learning evaluation service according to an exemplary embodiment of the present invention.

Referring to FIG. 6, when the test management server 106 generates test information (S600), and requests the broadcast scheduling server 116 to broadcast a schedule (S602), the broadcast scheduling server 604 determines a time zone during which a test will be broadcast. A broadcast programming process is performed to determine a transmission time of each fingerprint file and individual view file within the range (S604), and the broadcast programming information is transmitted to the broadcast server 104 (S606).

The client 100 of the candidate who wants to receive a learning evaluation transmits the candidate login information by accessing the web server 102 (S608), and the web server 102 authenticates the candidate through the candidate ID and password or the candidate reception number. The login response information is transmitted to the candidate client 100 (S610).

The candidate client 100 requests the web server 102 to view a test (S612).

When the broadcast time starts, the time synchronization server 108 synchronizes the time of the candidate client 100 and the broadcast server 104 (S614), after which the broadcast server 104 is fingerprinted according to preset broadcast programming information. The file is transmitted to the candidate client 100 in a streaming manner (S616).

The learning evaluation application installed in the candidate client 100 performs a process of outputting the problem information and broadcasting the transmitted fingerprint (S618), and allows the candidate to check (or watch) the problem and the fingerprint.

Thereafter, after one fingerprint transmission is made, the broadcast server 104 waits for a time for a pool of problems belonging to the fingerprint (S620), and when the transmission time of the next fingerprint file is reached, the next fingerprint to the candidate client 100 is reached. The file is streamed and transmitted (S622).

The broadcast server 104 determines whether all fingerprint files have been transmitted (S624), and when all fingerprint files have been transmitted, stops the fingerprint file broadcast (S626).

The learning evaluation application installed in the candidate client 100 determines whether the candidate has selected the end test button (S628), and if there is a test end button selection of the candidate before the end of the test time, the test pool information of the candidate is managed. The server 106 transmits to the server 106 (S634).

On the other hand, the time synchronization server 108 determines whether the test time has ended (S630), and when the test time ends, transmits the test end information to the candidate client 100 (S632), the candidate client 100 The learning evaluation application transmits the test pool information to the test management server 106 until the test is terminated after the test is forcibly terminated when the test end information is received (S634).

The test management server 106 scores the candidate's test pool information (S636), and stores the scored test result in the candidate information DB 114 (S638).

7 is a flowchart illustrating a retesting process in a preferred embodiment of the present invention.

Referring to FIG. 7, when the test is abnormally terminated due to a failure of the test taker (S700), the network, the broadcast server 104, or the test taker client 100 (S702), the broadcast server 104 performs a test. The abnormal termination information of the test is transmitted to the management server 106 (S704).

Accordingly, the test management server 106 transmits the retest authentication number to the candidate client 100 (S706) and requests the rebroadcasting configuration to the broadcast programming server 116 (S708).

The broadcast programming server 116 performs a re-broadcasting process through pre-stored test information or test information transmitted from the test management server 106 (S710).

The re-broadcasting process is to determine the broadcast time zone as the time zone set to re-broadcast, and to determine the transmission time of the problem file including the text and the fingerprint file and the individual problem question or viewing file transmission time within the determined time zone.

The broadcast scheduling server 116 transmits rebroadcasting schedule information to the broadcast server 104 (S712).

Thereafter, when the candidate client 100 requests the retest to the web server 102 through the retest certification number transmission (S714), the web server 102 performs a process of authenticating the candidate through the retest certification number (S716). .

If the candidate is authenticated by the retest certification number, the connection between the candidate client 100 and the broadcast server 104 is established. Accordingly, the candidate receives the retest information through the rebroadcast channel of the broadcast server 104 and proceeds with the retest. It is made (S718).

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and those skilled in the art will be able to make various modifications, changes, and additions within the spirit and scope of the present invention. Additions should be considered to be within the scope of the following claims.

As described above, according to the present invention, there is an advantage in that the candidate's random fingerprint file reproduction can be prevented by transmitting the fingerprint file for learning evaluation in a streaming manner at a predetermined time interval.

In addition, according to the present invention, there is an advantage that the learning evaluation can be performed in the same manner as offline by determining the transmission time of the fingerprint file using the problem solving time information belonging to the fingerprint.

In addition, according to the present invention, there is an advantage that accurate and fair learning evaluation can be made by preventing any reproduction of the candidate.

In addition, according to the present invention, there is an advantage in that retesting is possible by organizing re-broadcasting to the test taker who abnormally terminated the test among users connected to a predetermined real-time broadcasting time.

In addition, according to the present invention, since the problem information is extracted compared to a predetermined test time, there is an advantage that a problem suitable for the test time can be combined even in the case of random extraction.

In addition, according to the present invention, since there is a problem of having an independent and subordinate relationship in one fingerprint, there is an advantage that various problems can be provided for the same fingerprint.
