Here, the cognitive ability knowledge graph to be measured may include N nodes and correlation coefficients between any two of the N nodes. Wherein N is a positive integer. And each node corresponds to the cognitive competence sub-ability to be tested in the preset cognitive competence sub-ability set to be tested one by one. And each node can correspond to a test task set for testing the cognitive ability sub-capability to be tested corresponding to the node.

For ease of understanding, please refer to fig. 2B, which illustrates a schematic diagram of one embodiment of a knowledge-graph of measured cognitive abilities according to the present disclosure. As shown in fig. 2B, the cognitive ability knowledge graph to be tested includes 5 nodes, which correspond to the cognitive ability sub-ability a1 to be tested, the cognitive ability sub-ability a2 to be tested, the cognitive ability sub-ability A3 to be tested, the cognitive ability sub-ability a4 to be tested, and the cognitive ability sub-ability a5 to be tested, respectively. The cognitive ability sub-capability A1 to be tested corresponds to a test task T1 and a test task T2, the cognitive ability sub-capability A2 to be tested corresponds to a test task T3, a test task T4 and a test task T5, the cognitive ability sub-capability A3 to be tested corresponds to a test task T6 and a test task T7, the cognitive ability sub-capability A4 to be tested corresponds to a test task T8 and a test task T9, and the cognitive ability sub-capability A5 to be tested corresponds to a test task T10, a test task T11 and a test task T12. The numerical values displayed on the connecting lines between different nodes in fig. 2B are used to represent the correlation coefficients between the cognitive competence sub-abilities to be tested corresponding to the two ends of the connecting line. For example, in fig. 2B, the correlation coefficients between the cognitive ability sub-ability a1 to be detected and the cognitive ability sub-ability a2 to be detected, the cognitive ability sub-ability A3 to be detected, the cognitive ability sub-ability a4 to be detected, and the cognitive ability sub-ability a5 to be detected are 0.4, 0.2, 0.6, and 0.8, respectively, which indicates that the correlation between the cognitive ability sub-ability a1 to be detected and the cognitive ability sub-ability a5 to be detected is the highest, and the correlation between the cognitive ability sub-ability A3 to be detected is the lowest.

Here, the set of cognitive abilities to be measured may be a set consisting of different cognitive abilities to be measured, which is previously prepared by a technician (e.g., a psychologist or a social specialist) according to professional knowledge (e.g., psychological or social knowledge) and stored in the execution body.

The set of test tasks for sensory memory may include, for example, picture portion reporting test tasks. The picture part report test task refers to: multiple different target objects are presented on the display device and disappear quickly (e.g., within 1 second), requiring the subject to remember each target object and report out the specific target object on a task request in subsequent tests. The target object may be, for example, color patches of different colors and/or shapes, arrows of different colors and/or orientations, objects commonly seen in life, image objects of a human face, different fruits, vegetables, animals, or cartoon characters, and the like.

Here, short-term memory ability may refer to the ability of a subject to temporarily store a certain amount of material in a mental working memory. And the test task set corresponding to the short-term memory ability is used for testing the short-term memory ability of the testee. The test task set corresponding to the short-time memory ability can comprise a multi-position memory breadth test task and a language memory breadth test task. The task of testing the memory width of the position refers to: multiple target objects are presented simultaneously or sequentially on a display device, the subject is asked to remember each target object in turn and to report the target objects once presented in a desired, reverse, or other specific order in subsequent tests. The target object may be a material such as a spatial position, a sound, a picture, or a color, an orientation, etc. The language memory breadth testing task is as follows: multiple text or digital objects are presented simultaneously or sequentially on a display device, the subject is asked to remember each target object in turn and to report the target objects once presented in a desired, reverse, or other specific order in subsequent tests.

And the test task set corresponding to the semantic memory ability is used for testing the semantic memory ability of the testee. The test task set corresponding to the semantic memory ability may include, for example, a picture naming task. The picture naming test task is as follows: a series of images are presented continuously on a display device, requiring the subject to quickly speak the name of the target object to which the image corresponds. These objects may be, for example, designated objects, animals, plants, humans, etc.

Here, the contextual memory capacity may be the capacity of the subject to memorize a specific event. And the test task set corresponding to the contextual memory ability is used for testing the contextual memory ability of the subject. The test task set corresponding to the contextual memory capability may include, for example, a human brain-picture contact memory test task. The human brain-picture association memory test task may refer to, for example: the two different images are presented on the display device in pairs or in sequence, the subject is required to remember the relationship between the two different images, and the clue text is presented after a certain time, so that the subject can recall the image matched with the clue according to the prompt of the clue text. These images may be images indicating different visual, auditory, tactile, olfactory, etc. channels of perception or different object types.

Here, the skill memory ability may be: the subject, based on the feedback, quickly learns the ability to react correctly to different stimuli according to the rules. And the testing task set corresponding to the skill memory ability is used for testing the skill memory ability of the subject. The set of test tasks for skill memory may include, for example, probabilistic learning test tasks. The probability learning test task is as follows: the target object is presented on the display device, the subject is required to make a certain action response to the target object, and the optimization behavior is adjusted according to the error feedback, so that the accuracy of the action response is gradually improved.

In some alternative embodiments, the cognitive ability to be measured may be attention.

Based on the above optional embodiment, the preset cognitive ability sub-capability set to be tested may be a preset attention capability set, and the preset attention capability set may include at least one of the following items: capacity of attention, selective attention, continuous attention, automatic control, reaction.

Here, note that the capacity capability may refer to the ability of a subject to remember multiple targets simultaneously. The set of test tasks corresponding to attention capacity capability is used to test the attention capacity capability of the subject. The set of test tasks corresponding to the attention capacity capability may include, for example, attention capacity type test tasks. The attention capacity type test task means: presenting a plurality of different target objects on a display device requires the subject to remember the look and location of each target object and to accurately recall or select the corresponding target object for subsequent testing. The target object may be, for example, a color patch of different colors and/or shapes, an arrow of different colors and/or orientations, an object commonly seen in life, a human face, and the like.

Selecting attentiveness may refer to the ability of a subject to focus attention on a particular target among multiple targets. And selecting a test task set corresponding to the attention ability for testing the attention ability of the subject. The set of test tasks corresponding to the selected attention capabilities may include, for example, multi-target tracking type test tasks. The multi-target tracking type test task is as follows: presenting the plurality of irregularly moving objects on the display device requires the subject to remember a particular object of the plurality of irregularly moving objects and identify the previous particular object in a subsequent test. The target may be an image of a firefly, a bee, or a butterfly, for example.

The continuous attention capability may be: the ability of the subject to continue to focus on the target. The set of test tasks corresponding to the sustained attentional capacity is used to test the sustained attentional capacity of the subject. The set of test tasks for which the continuous attention capabilities correspond may include, for example, continuous job tasks. The continuous operation test task means: a series of targets are continuously presented on a display device, requiring the subject to continue to react to the targets for a period of time. These objects may be designated numbers, text, graphics, and the like.

Here, the autonomous capability may be: the ability of the subject to control impulsive behavior. And the test task set corresponding to the automatic control ability is used for testing the automatic control ability of the testee. The set of test tasks for which the autonomous capability corresponds may include, for example, impulse-control type test tasks. The impulse control type test task may be, for example: the method comprises the steps that a rolling image is presented on a display device, the image comprises different channel images and a target object, a subject is required to control the target object to pass through a channel corresponding to a specified channel image according to a preset requirement, and the resistance to impulse type testing task can be used for testing the ability of the subject to get rid of habits instead of passing through the channel corresponding to the same channel image according to inertia habits.

Here, the reaction capacity may be: the ability of a subject to respond rapidly to an external stimulus. The set of test tasks corresponding to the responsiveness is used to test the responsiveness of the subject. The set of test tasks for which the reaction capability corresponds may comprise, for example, reaction speed type test tasks. The reaction rate type test task means: presenting the target object on a display device, asking the subject to make a specified action when the target object appears, and calculating a time interval between the appearance of the target object and the completion of the specified action by the subject, by which the responsiveness of the subject can be tested. It will be appreciated that the shorter the time interval, the more responsive the subject; conversely, the longer the time interval, the less responsive the subject.

In some alternative embodiments, the knowledge-map of cognitive abilities to be measured may also be pre-established by the knowledge-map establishing step 300 shown in fig. 3. The knowledge-graph establishing step 300 may include the following steps 301 to 304:

and 301, acquiring an initial cognitive ability knowledge graph to be detected.

Here, the initial cognitive ability knowledge graph to be tested includes N nodes, and each node in the initial cognitive ability knowledge graph to be tested corresponds to a cognitive ability sub-ability to be tested in the preset cognitive ability sub-ability set one by one. And each node in the initial cognitive ability knowledge graph to be tested corresponds to a test task set used for testing the cognitive ability sub-ability to be tested corresponding to the node.

Step 302, a training sample set is obtained.

Here, the training sample may include sample task performance parameter information of a test task in a test task set corresponding to a node in the initial cognitive ability knowledge graph to be tested, which is completed by the sample subject, and a labeled test value corresponding to each cognitive ability sub-ability to be tested in a preset cognitive ability sub-ability set to be tested. Namely, the task performance parameter information of a test task completed by a sample test subject and the corresponding labeled test value of the cognitive competence of the sample test subject in each different cognitive competence to be tested based on the task performance parameter information of the test task are recorded in the training sample. Here, the corresponding labeled test value for each of the different cognitive abilities to be tested may be obtained by evaluating and labeling each of the different cognitive abilities to be tested in the preset cognitive ability sub-ability set of the sample subject according to the task performance parameter information of the sample subject by a professional technician (e.g., a psychologist or a socialist).

The training sample set can be considered as recording task performance parameter information of a plurality of sample subjects completing test tasks corresponding to different to-be-tested cognitive competencies in the preset to-be-tested cognitive competence sub-ability set and corresponding labeled test values aiming at the different to-be-tested cognitive competencies.

It should be noted that in practice, a plurality of sample subjects may be comprised of a representative population. The representative population is a population that simulates the composition of a large sample population with a small number of sample subjects and has a composition that is substantially identical or similar to that of the large sample population. For example, if a large group of individuals includes 5% of alzheimer patients and 5% of children with difficulty in memory development, 5% of alzheimer patients and 5% of children with difficulty in memory development may be included in the plurality of sample subjects. For example, when a large sample group includes 10% of patients with hyperactivity, 10% of patients with hyperactivity may be included in the sample subjects.

And 303, adjusting the correlation coefficient between any two nodes in the initial cognitive ability knowledge graph to be detected based on the training sample set by using a machine learning method.

Here, a preset machine learning model may be obtained first, and the machine learning model may include a correlation coefficient between each node in the initial cognitive ability knowledge graph to be tested, or alternatively, may further include a correlation coefficient between each test task in the test task set corresponding to each node and the node. The machine learning model is used for representing the corresponding relation between task performance parameter information of a test task and each to-be-tested cognitive ability sub-ability test value in a preset to-be-tested cognitive ability sub-ability set. Here, the machine learning model may include, for example, at least one of: structural equation models, artificial neural network models, and the like.

Then, the following parameter adjustment operations are executed until the preset training end condition is met:

the parameter adjustment operation may include: firstly, inputting sample task performance parameter information (specifically, sample task identification and corresponding task performance parameter information) in a training sample set into the machine learning model to obtain an actually output test value aiming at each cognitive ability sub-ability to be tested; and then, adjusting model parameters of the machine learning model based on the difference between the actually output test value aiming at each to-be-tested cognitive competence sub-ability and the labeled test value of each corresponding to-be-tested cognitive competence sub-ability in the training sample. The machine learning model includes correlation coefficients between nodes in the initial cognitive ability knowledge graph to be tested, or optionally may also include correlation coefficients between each test task in the test task set corresponding to each node and the node. Furthermore, the adjustment of the correlation coefficient between each node in the initial cognitive ability knowledge graph to be tested can be realized in the parameter adjustment operation process, or alternatively, the correlation coefficient between each test task in the test task set corresponding to each node and the node can also be adjusted.

Here, the training end condition may include at least one of: the time for executing the parameter adjustment operation reaches the preset duration, the times for executing the parameter adjustment operation reaches the preset times, and the difference between the actually output test value for each to-be-tested cognitive ability sub-capability and the labeled test value of each corresponding to-be-tested cognitive ability sub-capability in the training sample is smaller than the preset difference threshold.

Here, various implementations may be adopted to adjust the model parameters of the machine learning model based on the difference between the actually output test value for each cognitive competence sub-capability to be tested and the labeled test value of each corresponding cognitive competence sub-capability to be tested in the training sample. For example, Stochastic Gradient Descent (SGD), Newton's Method, Quasi-Newton Method, Conjugate Gradient Method, heuristic optimization Methods, and various other optimization algorithms now known or developed in the future may be used.

Through step 303, the correlation coefficient between the nodes in the initial cognitive ability knowledge graph to be tested may be adjusted, or alternatively, the correlation coefficient between the test tasks and the nodes in the test task set corresponding to the nodes may also be adjusted.

And step 304, determining the initial cognitive ability knowledge graph to be detected as the cognitive ability knowledge graph to be detected.

The knowledge graph establishing step 300 shown in fig. 3 is adopted to establish the knowledge graph of the cognitive abilities to be tested in advance, and since the knowledge graph is established based on task completion parameter information of actually completing the test tasks by a plurality of sample testees and corresponding cognitive ability sub-ability labeled test values to be tested, correlation coefficients among nodes in the knowledge graph of the cognitive abilities to be tested represent correlation degrees among the corresponding cognitive abilities to be tested, and thus, in the subsequent test operation in step 202, a basis is provided for estimating the cognitive ability sub-ability test value to be tested of the node which does not complete the test operation according to the cognitive ability sub-ability test value to be tested corresponding to the node which completes the test operation.

Step 202, taking the central node of the N nodes as the current node to execute the test operation.

Here, first, a central node among N nodes in the cognitive ability knowledge graph to be measured may be determined in various implementations. For example, a preset node among the N nodes may be determined as the center node. For another example, a randomly selected node of the N nodes may be determined as the central node.

In some alternative embodiments, the central node of the N nodes may be determined in the following manner:

in a first step, the correlation coefficient sum of each of the N nodes may be determined.

Here, the correlation coefficient sum of a node is the sum of correlation coefficients of nodes other than the node among the N nodes and the node.

In the second step, the node with the largest correlation coefficient and the largest correlation coefficients among the N nodes may be determined as the center node.

Namely, the node with the highest degree of relevance and contact with other nodes in the N nodes is taken as a central node to start the subsequent test operation.

And then, taking the central node as the current node to execute the test operation.

Here, the test operation may include step 2021 to step 2026 as shown in fig. 2C:

step 2021, determining the task to be tested in the test task set associated with the current node.

Here, various implementations may be employed to determine the task to be tested in the test task set associated with the current node. For example, a preset test task in the test task set associated with the current node may be determined as a task to be tested. For another example, a randomly selected test task in the test task set associated with the current node may also be determined as a task to be tested.

Optionally, when the cognitive ability knowledge graph to be tested includes correlation coefficients between the test tasks and the nodes, the test task with the largest correlation coefficient between the current node and the test task in the test task set associated with the current node may also be determined as the task to be tested. It can be understood that, since the correlation coefficient between the test task and the node in the cognitive ability knowledge graph to be tested represents the correlation degree between the test task and the cognitive ability sub-ability to be tested corresponding to the node, the task to be tested determined according to the optional embodiment is most relevant to the cognitive ability sub-ability to be tested corresponding to the current node in the test task set associated with the current node, and the cognitive ability sub-ability to be tested corresponding to the current node by the subject can be tested quickly by starting testing from the task to be tested, so that the testing time is reduced, and the testing efficiency is improved.

For ease of understanding, please continue to refer to fig. 2B, where fig. 2B shows that the numerical value displayed on the connection line between the sub-capability node of the cognitive ability to be tested and the test task node in the knowledge graph of the cognitive ability to be tested is used to represent the correlation coefficient between the test task corresponding to one end of the connection line and the sub-capability of the cognitive ability to be tested corresponding to the other end of the connection line. For example, in fig. 2B, the correlation coefficient between the cognitive ability sub-capability a1 to be tested and the test task T1 is 0.41.

Step 2022, providing the task to be tested, and obtaining task completion parameter information of the subject completing the task to be tested.

For example, when the task to be tested is a program instruction sequence, the program instruction sequence corresponding to the task to be tested may be executed, and task completion parameter information in an interaction process between the subject and the program instruction sequence, that is, in a process of completing the task to be tested, may be obtained. Here, the task completion parameter information may be various related information of the subject in the process of completing the task to be tested.

Step 2023, determining the test value of the cognitive competence sub-ability of the subject corresponding to the current node according to the task completion parameter information.

Here, the logic may be determined according to a test value corresponding to the cognitive competence sub-ability to be tested corresponding to the current node, and the test value of the cognitive competence sub-ability to be tested corresponding to the current node may be determined by the subject according to the task completion parameter information of the subject completing the task to be tested. Here, the test value determination logic corresponding to the cognitive performance sub-capability to be tested corresponding to the current node may be a calculation formula for calculating task completion parameter information of the task to be tested to obtain a test value of the cognitive performance sub-capability to be tested corresponding to the current node, or the test value determination logic corresponding to the cognitive performance sub-capability to be tested corresponding to the current node may be a correspondence table for representing a correspondence between the task completion parameter information of the task to be tested and the test value corresponding to the cognitive performance sub-capability to be tested corresponding to the current node. The calculation formula or the corresponding relationship table may be a calculation formula or a corresponding relationship table which is pre-formulated and stored in the execution main body by a technician based on the task completion parameter information corresponding to the task to be tested completed by a large number of sample testees and the statistics of the labeled test value of the cognitive competence to be tested corresponding to the current node by the sample testees.

It can be understood that the task to be tested is used for testing the cognitive competence sub-ability to be tested corresponding to the current node, and in step 2023, the test value of the cognitive competence sub-ability to be tested corresponding to the current node, which is determined according to the task completion parameter information of the subject completing the task to be tested, of the subject can be used for characterizing the degree of the subject in the cognitive competence sub-ability to be tested corresponding to the current node.

Step 2024, estimating the test value of the cognitive ability sub-ability to be tested corresponding to the node which does not execute the test operation in the cognitive ability knowledge graph to be tested, according to the test value of the cognitive ability sub-ability to be tested corresponding to each node which executes the test operation and each correlation coefficient in the cognitive ability knowledge graph to be tested.

Here, the correlation coefficient between two different nodes in the cognitive ability knowledge graph to be measured is used for representing the correlation degree between the cognitive ability sub-abilities to be measured corresponding to the two different nodes. That is, assuming that the correlation coefficient between two different nodes N1 and N2 in the cognitive ability knowledge graph to be tested is higher, it indicates that the correlation degree between the cognitive ability sub-ability a1 and a2 to be tested corresponding to the two different nodes N1 and N2 is also higher, and accordingly it can be understood that if the test operation of steps 2021 to 2026 has been performed on the cognitive ability sub-ability a1 to be tested and the test value of the subject at the cognitive ability sub-ability a1 to be tested is obtained, and since the correlation degrees of the cognitive ability sub-ability a2 and a1 to be tested are higher, the test value of the subject at the cognitive ability sub-ability a2 to be tested can be approximately estimated by using the test value of the subject at the cognitive ability sub-ability a1 to be tested, and the test of the cognitive ability sub-ability a2 to be tested is not required.

Specifically, step 2024 may be performed, for example, as follows:

for each node which does not execute the test operation in the knowledge graph to be tested for the cognitive ability, executing the following first calculation step to determine a test value of the sub-ability of the cognitive ability to be tested corresponding to the node which does not execute the test operation by the subject: firstly, determining nodes, of which correlation coefficients with the nodes are larger than a preset correlation coefficient threshold value, of all nodes which correspond to a subject and have executed test operation in a cognitive ability knowledge graph to be tested as related nodes; and then, determining the average value of the cognitive abilities corresponding to the relevant nodes corresponding to the subject as the cognitive ability test value corresponding to the node which does not execute the test operation.

In some alternative embodiments, step 2024 may also be performed as follows:

and for the nodes which do not execute the test operation in the cognitive ability knowledge graph corresponding to the test subject, carrying out weighted summation on the test values of the to-be-tested cognitive ability sub-ability corresponding to each node which has executed the test operation by the test subject according to the correlation coefficients of each node which has executed the test operation and the node which does not execute the test operation, and determining the result of the weighted summation as the test value of the to-be-tested cognitive ability sub-ability corresponding to the node which does not execute the test operation. In the test values of the cognitive competence sub-abilities to be tested corresponding to the nodes which do not execute the test operation in the cognitive competence knowledge graph to be tested, which are calculated according to the optional implementation manner, the test values of the cognitive competence sub-abilities to be tested corresponding to the nodes which execute the test operation in the cognitive competence knowledge graph to be tested of all the testees are reflected, and in other words, more reference data are provided, so that the test values of the cognitive competence sub-abilities to be tested corresponding to the nodes which do not execute the test operation in the cognitive competence knowledge graph to be tested of the testees can be more accurately evaluated.

At step 2025, it is determined whether a predetermined test operation end condition is satisfied.

Here, the preset test operation end condition may be a condition that is previously prepared and stored to the execution subject by a technician (e.g., a psychological or social expert) according to a summary of professional knowledge (e.g., psychological or social knowledge) and practical experience. If the preset test operation ending condition is met, the test operation is ended, and then the cognitive competence sub-ability to be tested corresponding to the node which does not execute the test operation in the cognitive competence knowledge graph to be tested is not tested to the testee.

In some optional embodiments, the preset test operation end condition may include at least one of:

firstly, the prediction accuracy of each node which has executed the test operation in the cognitive ability knowledge graph to be tested and corresponds to the node which does not execute the test operation by the subject is larger than a preset accuracy threshold.

Secondly, testing operation is executed on each node in the N nodes in the cognitive ability knowledge graph to be tested.

That is, if at least one of the above two conditions is satisfied, it may be determined that the test operation is ended.

Regarding the first condition, the prediction accuracy of each node, which has performed the test operation, in the cognitive ability knowledge graph to be tested to the node which has not performed the test operation by the subject may be described as follows: the cognitive ability knowledge graph to be tested comprises N nodes, wherein M nodes are supposed to have executed test operation, and the rest (N-M) nodes have not executed test operation, wherein M is a positive integer less than or equal to N. Here, for each of the (N-M) nodes Ni on which no test operation is performed, the prediction accuracy of the M nodes on which the test operation has been performed with respect to the node Ni on which no test operation is performed may be calculated in various ways. For example, a variant interpretation rate, that is, a variant interpretation rate of a constructed regression equation between each node of the M nodes that have performed the test operation and the node Ni that has not performed the test operation may be determined as a prediction accuracy rate of the M nodes that have performed the test operation on the node Ni that has not performed the test operation. The first condition may be that the variation interpretation rate of each node, which has performed the test operation, in the cognitive ability knowledge graph to be tested by the subject to each node which has not performed the test operation is greater than a preset prediction accuracy threshold.

If the first condition is met, the estimation of the test value of the cognitive ability sub-ability to be tested corresponding to the node which does not execute the test operation in the cognitive ability knowledge graph to be tested is reliable according to the test value of the cognitive ability sub-ability to be tested corresponding to each node which executes the test operation in the cognitive ability knowledge graph to be tested, namely, the cognitive ability sub-ability to be tested corresponding to the node which does not execute the test operation in the cognitive ability knowledge graph to be tested can not be tested continuously.

If the second condition is met, namely after the testing operation on the to-be-tested cognitive competence sub-abilities corresponding to all the nodes in the to-be-tested cognitive competence knowledge graph is completed, the testing values of the to-be-tested cognitive competence sub-abilities corresponding to all the nodes in the to-be-tested cognitive competence knowledge graph are obtained, and the testing operation is not required to be executed. In some optional embodiments, in the case that it is determined in step 2025 that the preset test operation ending condition is not satisfied, the execution main body may go to the following step 2026 to execute:

step 2026, determining the next node to be tested according to the correlation coefficient between the node which does not execute the testing operation in the cognitive ability knowledge graph to be tested corresponding to the subject and the current node.

That is, if the executing entity determines not to end the testing operation in step 2025, various implementation manners may be adopted to determine the next node to be tested from the nodes not performing the testing operation in the cognitive competence knowledge graph corresponding to the test subject according to the correlation coefficient between the node not performing the testing operation in the cognitive competence knowledge graph corresponding to the test subject and the current node. Because the correlation coefficient between two different nodes in the cognitive competence knowledge graph to be tested is used for representing the correlation degree between the cognitive competence sub-competence to be tested corresponding to the two different nodes. That is, assuming that the current node in the cognitive competence knowledge graph to be tested is N3, the test subject corresponds to a node Ni in each node that does not perform the test operation in the cognitive competence knowledge graph to be tested, if the correlation coefficient ratio of Ni to N3 is relatively large, it can be considered that the cognitive competence sub-capability to be tested corresponding to the node Ni is relatively similar to the cognitive competence sub-capability to be tested corresponding to the node N3, and since the cognitive competence sub-capability to be tested corresponding to the node N3 of the test subject has been tested, it is not necessary to test the cognitive competence sub-capability to be tested corresponding to the node Ni. On the contrary, if the correlation coefficient ratio between Ni and N3 is smaller, it can be considered that the cognitive ability sub-capability to be tested corresponding to the node Ni is not similar to the cognitive ability sub-capability to be tested corresponding to the node N3, and although the cognitive ability sub-capability to be tested corresponding to the node N3 of the subject has been tested, the cognitive ability sub-capability to be tested corresponding to the node Ni needs to be tested.

According to the above description, the executing body may select, as the next node to be tested, a node having a smaller correlation coefficient with the current node from the nodes that do not execute the testing operation in the cognitive ability knowledge graph corresponding to the subject to be tested.

Alternatively, step 2026 may be performed as follows: and determining the node with the minimum correlation coefficient with the current node in each node which does not execute the test operation in the cognitive ability knowledge graph to be tested corresponding to the testee as the next node to be tested. Namely, the node which is least related to the current node is selected as the next node to be tested.

In step 2027, the next node to be tested is the current node, and the test operation is continuously executed.

That is, with the next node to be tested determined in step 2026 as the current node, go to step 2021 to continue execution, so as to test the cognitive competence sub-capability of the subject to be tested corresponding to the current node updated by the next node to be tested and obtain a corresponding test value, estimate the test values of other nodes not having performed the test operation based on the test values of all nodes having performed the test operation corresponding to the subject, and determine whether to end the test operation again, if it is determined in step 2025 to end the test operation again, then not continue to execute the test operation again.

In some optional embodiments, based on the optional embodiment that the test task with the largest correlation coefficient with the current node in the test task set associated with the current node in step 2021 is determined as the task to be tested, the executing main body may further perform the following steps 203 'to 206' after performing step 202:

and step 203', determining the node with the minimum test value of the sub-capacity of the cognitive ability to be tested corresponding to the subject in the nodes in the cognitive ability knowledge graph to be tested as the node with the weakest capacity.

That is, the cognitive abilities to be tested corresponding to each node in the cognitive ability knowledge graph to be tested can be quickly tested through the

steps

201 and 202, and whether the test is accurate or not needs to be further confirmed. Specifically, if the subject scores the lowest for a particular cognitive competence sub-capacity to be tested, it is likely that the test for that cognitive competence sub-capacity to be tested is inaccurate, and testing may need to be continued to improve accuracy. That is, the weakest cognitive competence sub-capacity to be measured of the subject can be first found according to step 203'. And then go to step 204'.

And 204', determining the test task with the non-highest correlation coefficient with the node with the weakest ability in the test task set corresponding to the node with the weakest ability as the first task to be tested.

Since the test task with the largest correlation coefficient with the weakest node is selected from the test task set corresponding to the weakest node determined in step 203 ' by the subject to be tested in step 2021, the test task with the largest correlation coefficient with the weakest node does not need to be tested again, so that step 204 ' may be performed first to determine the first task to be tested, and then step 205 ' may be performed. For example, the first task to be tested may be a test task with the highest correlation coefficient with the weakest node in the test task set corresponding to the weakest node.

Step 205', provide a first task to be tested, and obtain the task completion parameter information of the subject completing the first task to be tested.

Namely, the test task is changed to test the cognitive competence sub-ability to be tested corresponding to the weakest node of the test subject again, so that the accuracy of the cognitive competence sub-ability test to be tested corresponding to the weakest node is improved.

And step 206', determining a test value of the cognitive competence sub-ability to be tested corresponding to the node with the weakest ability corresponding to the subject according to the task completion parameter information of the first task to be tested completed by the subject.

Here, the specific operation of step 206' and the technical effect thereof are substantially the same as the operation and effect of step 201 and step 2023 in the embodiment shown in fig. 2A, and are not repeated herein.

According to the optional implementation mode, the cognitive competence replacement test task to be tested with the lowest score of the testee can be tested again, so that the test accuracy of the testee is improved.

In some optional embodiments, based on the optional embodiment that the test task with the largest correlation coefficient with the current node in the test task set associated with the current node is determined as the task to be tested in step 2021, the execution subject may further perform the following steps 203 "to 204" after performing step 202:

in step 203 '', the node of the cognitive ability to be tested, where the test value of the cognitive ability sub-ability to be tested corresponding to the subject is smaller than the preset test value threshold, is determined as the node to be tested.

That is, if the score of the cognitive competence sub-ability of the subject to be tested is too low, the test may be inaccurate, and the test needs to be continued, step 203 ″ is executed, so that it can be determined that the cognitive competence sub-ability to be tested corresponding to the node to be tested needs to be continuously tested.

In step 204 '', a successive test operation is performed for each node to be tested.

Namely, the cognitive competence sub-abilities to be tested corresponding to all the nodes to be tested are continuously tested to obtain the test values corresponding to the cognitive competence sub-abilities to be tested. Wherein, the measurement continuing operation specifically comprises:

firstly, determining a test task with the highest correlation coefficient with the node to be tested in a test task set corresponding to the node to be tested as a second task to be tested.

As can be seen from the foregoing description of the optional embodiment, similarly, here, for the cognitive competence sub-ability to be tested corresponding to the node to be tested, since the test task with the largest correlation coefficient between the node to be tested and the test task in the test set corresponding to the node to be tested is already tested in step 2021, the test task needs to be replaced to perform the test again, so as to improve the accuracy of the test on the cognitive competence sub-ability to be tested corresponding to the node to be tested by the subject.

And secondly, providing a second task to be tested, and acquiring task completion parameter information of the testee for completing the second task to be tested.

Thirdly, according to the task completion parameter information of the subject for completing the second task to be tested, determining the test value of the cognitive competence sub-ability to be tested corresponding to the node to be tested by the subject.

According to the optional implementation mode, the replacement test task of the cognitive competence subtasks to be tested with too low scores of the testees can be tested again, so that the test accuracy of the testees is improved.

In the cognitive ability testing method provided by the embodiment of the disclosure, each to-be-tested cognitive ability sub-ability in the to-be-tested cognitive ability knowledge graph and the correlation coefficient between different to-be-tested cognitive ability sub-abilities are pre-established, then testing is started from the to-be-tested cognitive ability sub-ability corresponding to the central node in the to-be-tested cognitive ability knowledge graph, and in the testing process, the untested test value of the to-be-tested cognitive ability sub-ability is determined in real time according to the tested value of the to-be-tested cognitive ability sub-ability and the correlation coefficient between the nodes in the to-be-tested cognitive ability knowledge graph. If the fact that the tested cognitive competence sub-ability is not further tested is judged according to the tested value of the untested to-be-tested cognitive competence sub-ability, the testing can be finished, and the testing result of the comprehensive testing of the to-be-tested cognitive competence of the testee can be obtained without testing all the to-be-tested cognitive competence sub-ability. Compared with the situation that the comprehensive test can be realized only by testing all the cognitive competence sub-abilities to be tested, the method reduces the number and time of test tasks completed by the testee, is easier to obtain the cooperation of the testee, and improves the test efficiency. In some embodiments, the cognitive competence sub-capability to be tested with the lowest test value or the too low test value may be tested by replacing the test task, so as to further improve the test accuracy.

With continued reference to fig. 4, a flow 400 of yet another embodiment of a cognitive ability testing method according to the present disclosure is shown. The cognitive ability testing method comprises the following steps:

step 401, acquiring a cognitive ability knowledge graph to be detected.

Step 402, taking a central node of the N nodes as a current node to execute a test operation.

In this embodiment, the specific operations of step 401 and step 402 and the technical effects thereof are substantially the same as the operations and effects of step 201 and step 202 in the embodiment shown in fig. 2A, and are not repeated herein.

And 403, determining a task to be trained corresponding to the subject from a preset training task set according to the test value of each cognitive ability sub-ability to be tested in the preset cognitive ability sub-ability set corresponding to the subject.

Here, each training task in the preset training task set corresponds to a cognitive competence sub-capability to be tested in the preset cognitive competence sub-capability to be tested, and the training task is mainly used for training the subject in the cognitive competence sub-capability to be tested corresponding to the training task.

Because the test values of the cognitive abilities to be tested in the preset cognitive ability sub-ability set to be tested corresponding to the subject are obtained through the

steps

401 and 402, in order to improve the cognitive abilities of the subject to be tested in some cognitive abilities, various implementation modes can be adopted firstly, and the task to be trained corresponding to the subject is determined from the preset training task set according to the test values of the cognitive abilities to be tested in the preset cognitive ability sub-ability set to be tested corresponding to the subject.

In some alternative embodiments, step 403 may be performed as follows:

firstly, determining the cognitive ability sub-ability to be tested with the minimum test value of the cognitive ability sub-ability to be tested corresponding to the subject in a preset cognitive ability sub-ability set to be tested as the cognitive ability sub-ability to be trained. That is, the weakest cognitive ability of the subject is found as the cognitive ability sub-ability to be trained.

And then determining candidate training tasks corresponding to the cognitive competence sub-ability to be trained in the training task set.

Here, the number of candidate training tasks determined may be one or more than one.

And finally, determining the task to be trained in each determined candidate training task.

For example, a training task may be randomly selected from the determined candidate training tasks to be determined as the task to be trained.

For another example, when a candidate training task in the training task set is associated with a difficulty coefficient, a training task difficulty coefficient range corresponding to a to-be-trained cognition ability sub-ability test value can be determined according to a preset corresponding relationship between a test value range and the candidate training task difficulty coefficient range, where the to-be-trained cognition ability sub-ability test value is a test value corresponding to a to-be-trained memory cognition ability of the subject. And determining the candidate training tasks with the difficulty coefficients within the determined difficulty coefficient range in the determined candidate training tasks as the tasks to be trained.

In some optional embodiments, step 403 may also be performed as follows:

when the subject is associated with a corresponding cognitive ability to be improved to be tested (for example, for children with difficulty in memory development, elderly people with normal memory or elderly people with abnormal memory decline, the corresponding cognitive ability sub-ability to be improved may include sensory memory ability, short-term memory ability, semantic memory ability, situational memory ability and skill memory ability), the corresponding cognitive ability sub-ability to be tested may be selected from a preset training task set as a candidate training task for the cognitive ability sub-ability to be improved. And if the selected candidate training task is one, taking the candidate training task as the task to be trained corresponding to the subject. If more than one candidate training task is selected, the candidate training tasks can be randomly selected from the candidate training tasks to be used as the to-be-trained tasks. Or, when the training tasks in the training task set are associated with the difficulty coefficient, determining the training task difficulty coefficient range corresponding to the test value of the cognitive competence to be improved corresponding to the subject according to the corresponding relationship between the preset test value range and the training task difficulty coefficient range. And determining the candidate training tasks with the difficulty coefficients within the determined difficulty coefficient range in the selected candidate training tasks as the tasks to be trained.

Step 404, providing the task to be trained, and obtaining the task completion parameter information of the subject for completing the task to be trained.

For example, when the task to be trained is a program instruction sequence, the program instruction sequence corresponding to the task to be trained may be executed, and task completion parameter information in an interaction process of the subject and the program instruction sequence, that is, in a process of completing the task to be trained, may be acquired. Here, the task completion parameter information may be various related information of the subject in the process of completing the task to be trained.

Through the steps 401 to 404, on the basis of obtaining the test value of each cognitive ability sub-ability to be tested in the cognitive ability sub-ability set to be tested corresponding to the test subject, the training task can be determined according to the test result, the task completion parameter information of the test subject completing the training task is obtained after the training task is provided, and then the comprehensive test can be firstly carried out and then the corresponding training can be carried out, namely, the training is more targeted.

In some optional embodiments, the above flow 400 may further include the following steps 405 and 406:

and 405, taking a central node in the N nodes of the cognitive ability knowledge graph to be tested as a current node, and executing the test operation again to obtain a test value of the cognitive ability sub-ability to be tested in the preset cognitive ability sub-ability set to be tested after the test subject completes the training task.

And performing comprehensive evaluation test on the cognitive ability to be tested again on the test subject, and obtaining a test value corresponding to each cognitive ability sub-ability to be tested in the preset cognitive ability sub-ability set after the test subject completes the training task.

And step 406, determining training effect information of the subject according to the test value difference of the cognitive competence sub-ability to be tested in the preset cognitive competence sub-ability set to be tested before the subject completes the training task and after the subject completes the training task.

Since the test value difference corresponding to the cognitive competence sub-capability to be tested in the preset cognitive competence sub-capability set to be tested is obtained before the subject completes the training task in step 402, and the test value difference corresponding to the cognitive competence sub-capability to be tested in the preset cognitive competence sub-capability set to be tested is obtained after the subject completes the training task in step 405, in order to evaluate the training effect, various implementation modes can be adopted to determine the training effect information of the subject according to the difference between the two.

For example, the test value of the corresponding to-be-tested cognitive ability sub-capability in the preset to-be-tested cognitive ability sub-capability set after the test subject completes the training task is subtracted from the test value of the corresponding to-be-tested cognitive ability sub-capability in the preset to-be-tested cognitive ability sub-capability set before the test subject completes the training task, so as to obtain the test value difference of the corresponding to-be-tested cognitive ability sub-capability, and the test value difference is used as training effect information of the test subject, that is, the training effect information may include the test value difference corresponding to each to-be-tested cognitive ability sub-capability in the preset to-be-tested cognitive ability sub-capability set, so that the training effect of the test subject on each to-be-tested cognitive ability sub-capability can be evaluated through the training effect information.

For another example, the cognitive competence sub-capacity to be tested corresponding to the task to be trained determined in step 403 may be determined first. Then, subtracting the test value of the corresponding to-be-tested cognitive ability sub-ability corresponding to the to-be-trained task from the test value of the corresponding to-be-tested cognitive ability sub-ability corresponding to the to-be-trained task after the test subject completes the training task, further obtaining the test value difference of the corresponding to-be-tested cognitive ability sub-ability of the to-be-trained task, and using the test value difference as training effect information of the test subject, namely the training effect information only comprises the test value difference corresponding to the corresponding to-be-tested cognitive ability sub-ability of the to-be-trained task, and further evaluating the training effect of the corresponding to-be-tested cognitive ability sub-ability of the to-be-trained task of the test subject through the training effect information.

The training effect of the subject before and after training can be evaluated through

steps

405 and 406 to clarify the effect of the training task.

In some optional embodiments, the above flow 400 may further include the following step 407:

step 407, determining the completion degree score of the subject for completing the task to be trained according to the task completion parameter information of the subject for completing the task to be trained.

For example, a technician may formulate a corresponding relationship table or a calculation formula of the completion degree score in advance based on statistical analysis of task completion parameter information of tasks to be trained, in which the corresponding relationship table of the completion degree score is used to represent a corresponding relationship between task completion parameter information of the tasks to be trained and completion degree score of completing the tasks to be trained, and the calculation formula of the completion degree score is used to calculate each data in the task completion parameter information of the tasks to be trained to obtain the completion degree score of the tasks to be trained. Thus, here, based on the task completion parameter information of the subject completing the task to be trained, the corresponding lookup may be performed according to the correspondence table or the calculation formula may be performed to obtain the completion degree score of the subject completing the task to be trained.

That is, the task completion parameter information of the subject completing the task to be trained may be converted into a unified completion score, via step 407.

Based on the optional implementation manner of step 407, optionally, the process 400 may further include the following steps 408 to 410:

and step 408, determining the difficulty coefficient range of the next task to be trained according to the completion degree score of the subject for completing the task to be trained.

It can be understood that the completion degree score of the subject completing the task to be trained represents the completion degree of the subject to the task to be trained, if the completion degree score is higher, the completion degree of the subject is higher, and the difficulty coefficient of the next task to be trained can be improved; conversely, if the completion score indicates a lower completion, the difficulty factor for the next task to be trained may be maintained or decreased. It should be noted that, here, increasing, maintaining, or decreasing the difficulty factor of the next task to be trained refers to the difficulty factor relative to the difficulty factor of the current task to be trained.

Various implementations may be employed to specifically determine the difficulty factor range of the next task to be trained. For example, a score and difficulty correspondence table or a difficulty coefficient calculation formula may be prepared in advance by a professional (e.g., a psychologist or a socialist) according to professional knowledge, where the score and difficulty correspondence table is used to represent a correspondence between the completion degree score and the task difficulty coefficient range, and the difficulty coefficient calculation formula is used to calculate the completion degree score to obtain the difficulty coefficient range. Thus, here, based on the completion degree score of the subject completing the task to be trained, the difficulty coefficient range of the next task to be trained can be obtained by performing corresponding lookup according to the score and difficulty degree corresponding relation table or performing calculation according to the task difficulty coefficient calculation formula.

And 409, determining the candidate training task with the difficulty coefficient within the range of the determined difficulty coefficient of the next task to be trained in each determined candidate training task as the next task to be trained.

Here, the determined candidate training tasks may be the training tasks corresponding to the ability to be trained or the ability to be improved of the subject determined in the two alternative embodiments of step 403.

The next task to be trained determined in step 409 corresponds to the same cognitive competence sub-capacity to be tested as the task to be trained that the subject has completed, but the next task to be trained is a training task determined after the difficulty coefficient is adjusted according to the degree of completion of the task to be trained by the subject, is suitable for the specific situation of the subject, and can gradually improve the capacity to be trained or the capacity to be improved of the subject.

Step 410, providing the next task to be trained, and obtaining the task completion parameter information of the subject for completing the task to be trained.

Through steps 408 to 410, after the subject completes the task to be trained, the task difficulty of the next task to be trained can be customized according to the actual completion degree of the subject, and the cognitive ability to be tested of the subject is gradually improved.

It should be noted that, in practice, steps 407 to 410 may be repeated multiple times to train the cognitive ability of the subject to be trained or the cognitive ability to be improved, and the difficulty coefficient of the training task is determined again after each training, so as to gradually improve the cognitive ability of the subject to be trained or the cognitive ability to be improved.

Of course, in practice, after repeating steps 407 to 410 several times, after performing step 402 again to test the cognitive ability of the subject to be tested, then performing step 403 and step 404 again to determine and provide a new task to be trained according to the test result, and then repeating steps 407 to 410 until after performing step 403 to retest the subject, it indicates that training is no longer needed according to the test result, and the cognitive ability of the subject to be tested is improved.

As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2A, the flow 400 of the cognitive ability testing method in this embodiment has more steps of determining a training task, providing the training task, and obtaining training task completion parameter information according to a test result after testing the cognitive ability of the subject to be tested, optionally has more steps of evaluating a training effect, or optionally includes adjusting a difficulty coefficient of a next training task according to the training task completion parameter information and repeating the training. Therefore, the scheme described in the embodiment can provide the training task according to the test result of the cognitive ability test of the subject to be tested, and further improve the cognitive ability of the subject to be tested.
