Attached drawing, and obtain other embodiments.
One embodiment of the present of invention, as shown in Figure 1, a kind of check the method for correcting the learning performance of student, comprising:
The operation pictorial information of S100 acquisition user；
Specifically, obtaining the operation pictorial information of user.Wherein, the operation of user include paper, exercise, composition, diary,
All need teacher parent to check the written assignment corrected errors with mail etc., and the operation that paper, exercise etc. have Key for Reference is mainly to need
Check correcting errors for user's answer, on the one hand the open operation without Key for Reference such as composition, diary, mail needs to check format
Whether meet corresponding requirement, on the other hand needs to check whether its content meets common sense and logic.
Terminal take pictures to the operation of user obtaining operation pictorial information by camera, can also pass through
Operation pictorial information is obtained to the mode that the operation of user is scanned.It is same due to homework book typographical printing itself
Problem may be on being printed on the different paper of page two in front and back, then terminal itself identification is also needed to sentence in subsequent examination operation
It is disconnected, the speed of Inspection is on the one hand influenced, on the other hand if it is determined that mistake also results in the mistake of review of operations result.
It therefore, can be by when obtaining operation pictorial information for above-mentioned same problem not in same one page above scenario
It is marked according to the sequencing of acquisition, terminal is facilitated to be judged.
In addition, it is also possible to occur comprising multiple tracks topic above the same operation pictorial information obtained, but user works as
Before may only need check wherein together or multiple tracks topic, do not need at once to check all topics.Therefore, right
In the topic that the operation pictorial information of acquisition, user can need to check with unrestricted choice.Wherein, user can be in several ways
Carry out frame choosing.
S200 identifies that the operation pictorial information obtains corresponding operation type；
Specifically, the operation pictorial information that identification obtains obtains corresponding operation type, wherein operation type is broadly divided into
Two major classes: class of solving a problem and application composition class.The main distinction of the two is whether homework book has detailed problem description.
Wherein, class of solving a problem is mainly to have specific topic on homework book, and user answers according to the requirement of topic, such as mathematics
Calculation question, English Translation topic etc., the operation for class of solving a problem generally has a Key for Reference, but the Key for Reference for the topic of part
Also only one of answer mode, such as mathematical computations topic, calculated result is unique, but course of solving questions may have a variety of sides
Formula.In another example English Translation is inscribed, same semanteme may have a variety of expression ways.
And apply composition class mainly write a composition, diary, operation of the opening such as mail without Key for Reference, it may on homework book
There is the requirement such as type, theme, but essentially for such operation, final job content does not have uniqueness, can not lead to
It crosses and Key for Reference carries out matching comparison, so that judgement is corrected errors, but need to parse its particular content.
S300 selects corresponding review of operations mode according to the operation type；
Specifically, selecting corresponding review of operations mode according to the operation type identified.Wherein, class of solving a problem operation is corresponding
First review of operations mode, class of solving a problem operation generally all has Key for Reference, therefore first review of operations mode is to identify
Then topic information in operation pictorial information above work team searches for the corresponding Key for Reference of the topic information in exam pool,
Whether the answer content of user in identification operation pictorial information judges consistent to judge to use with Key for Reference to answer content
Family operation is corrected errors.
In addition, corresponding second review of operations mode of application composition class operation, since application composition class operation is typically no tight
The Key for Reference of lattice reference, therefore it is directed to the characteristics of applying composition class operation, which first checks for operation
Format it is whether correct, reexamine whether content therein meets common sense and logic.
S400 parses the operation pictorial information according to the review of operations mode, judges correcting errors for corresponding user job
And it is parsed.
Specifically, parsing the answer of user in the operation pictorial information of acquisition according to the corresponding review of operations mode of selection
Content judges correcting errors and being parsed for corresponding user job.If user's answer is wrong, erroneous point is pointed out to carry out weight
Point label, and parsed in detail by text or associated video, understand convenient for user, understands that user fundamentally
Principle.Furthermore it is also possible to which the higher similar operation of the degree of correlation is recommended to contact for user, further deepens the impression of user, make
User can veritably grasp relevant knowledge point securely.
In the present embodiment, by the identification of the operation type of the operation pictorial information to acquisition, corresponding operation inspection is chosen
The mode of looking into checks correcting errors for user job, and the operation of different work type uses more suitable review of operations mode, so as to
It is enough more rapidly and accurately to judge correcting errors for user job.In addition after checking that user job is corrected errors, based on huge exam pool
Topic as associated class can also be provided for user, further consolidate study.
Another embodiment of the invention is the optimal enforcement example of the above embodiments, as shown in Figure 2, comprising:
The operation pictorial information of S100 acquisition user；
S200 identifies that the operation pictorial information obtains corresponding operation type；
S300 selects corresponding review of operations mode according to the operation type；
S400 parses the operation pictorial information according to the review of operations mode, judges correcting errors for corresponding user job
And it is parsed.
S410 is when the review of operations mode first review of operations mode corresponding for class operation of solving a problem, according to the work
The written handwriting information of industry pictorial information acquisition user；
Specifically, when operation test mode first review of operations mode corresponding for class operation of solving a problem, according to flow diagram
The written handwriting information of piece acquisition of information user.If solving a problem class operation in operation pictorial information when corresponding user job, make
The person's handwriting for the answer content that the block letter of topic information in industry sheet and user oneself are write is not identical, therefore can recognize that
The wherein written handwriting information that user oneself writes.
S420 determines the topic information that user answers in the operation pictorial information according to the written handwriting information；
Specifically, if it is determined that according to the written handwriting information that user in operation pictorial information answers, then relatively
It just can determine that the topic information that user answers in operation pictorial information, that is, write on homework book except handwriting information and be exactly
Topic information.
S430 identifies that user is directed to the answer content of the topic information according to the written handwriting information；
Specifically, identifying that user is directed to the answer content of topic information according to written handwriting information, according to different topics
Type carries out different answer Context resolutions.For the simple topic of the answers content such as multiple-choice question, True-False, gap-filling questions, only need
Identification parsing is carried out to its result.For needing the topic of user's writing words it is noted that the content for needing to parse, example
Such as mathematics calculation question, necessary not only for identifying its final calculating answer, it is also necessary to parse its specific answer process.
S440 obtains the Key for Reference of the topic information；
Specifically, being scanned on exam pool and network according to the topic information of above-mentioned determination, so that it is determined that its is corresponding
Key for Reference.Therefore, it is necessary first to topic and its corresponding Key for Reference are collected, to establish huge exam pool for subsequent inspection
Be compared when looking into user job, and the physical strength information inside user job be not consistent in exam pool topic when, choosing
It selects and is further scanned on network, and add it to exam pool, to be updated to exam pool.
For the topic inside exam pool, can be classified first based on subject grade, it secondly can also be to involved by topic
And to knowledge point carry out parsing identification, then as mark topic is marked, convenient for it is subsequent for user recommend class
As topic.Meanwhile it being also convenient for the relevant topic of user's search specific knowledge point and learning.
The topic being consistent and corresponding Key for Reference are searched in exam pool for the topic information according to acquisition.First one by one
The words inside topic information is matched, if there is completely the same topic can be matched in exam pool, then it is corresponding to search for the topic
Key for Reference.
If search can choose keyword from topic information, pass through keyword less than completely the same topic
Retrieval, the topic retrieved is arranged according to the number of Keywords matching, and the matched more multiple rows of column of keyword number are more
It is forward.Then it selects the highest topic of matching degree or selects the corresponding Key for Reference of a certain road topic to examine for user
It looks into.
S450 compares the answer content and the Key for Reference, judges correcting errors and solving for user's answer
Analysis.
Specifically, the Key for Reference of the answer content of user and topic is compared, correcting errors simultaneously for user's answer is judged
It is parsed.If user's answer is wrong, erroneous point is pointed out to carry out emphasis label, and pass through text or associated video
It is parsed in detail, understands convenient for user, user is made fundamentally to understand principle.Furthermore it is also possible to recommend the degree of correlation higher
Similar operation for user contact, further deepen user impression, allow users to veritably grasp securely relevant
Knowledge point.
For example, topic information is one mathematical computations topic, comparing result show in the answer content of user calculating process and
Calculated result is all correct, but inscribes for this road mathematical computations, and also there are many settling modes, wherein also including more succinct
Calculation method, therefore prompt user also there are many calculation and parsed in detail, so that user be inspired to think deeply, avoided
Thinking and the elaborative faculty of user are defined in single thinking of solving a problem.
In the present embodiment, user job is checked using corresponding first review of operations mode for solving a problem class operation, mainly
Be corresponding Key for Reference is searched for by exam pool, and then judge correcting errors for user job, and no matter user job correct errors all into
The corresponding Analytic continuation of row, facilitates the thinking elaborative faculty outward bound for user.
Another embodiment of the invention is the optimal enforcement example of the above embodiments, as shown in Figure 3, comprising:
The operation pictorial information of S100 acquisition user；
S200 identifies that the operation pictorial information obtains corresponding operation type；
S300 selects corresponding review of operations mode according to the operation type；
S400 parses the operation pictorial information according to the review of operations mode, judges correcting errors for corresponding user job
And it is parsed.
S410 is when the review of operations mode first review of operations mode corresponding for class operation of solving a problem, according to the work
The written handwriting information of industry pictorial information acquisition user；
S420 determines the topic information that user answers in the operation pictorial information according to the written handwriting information；
S430 identifies that user is directed to the answer content of the topic information according to the written handwriting information；
S440 obtains the Key for Reference of the topic information；
S450 compares the answer content and the Key for Reference, judges correcting errors and solving for user's answer
Analysis.
S451 compares the answer content and the Key for Reference；
Specifically, the Key for Reference of the answer content of user and topic is seriatim compared, user's answer is judged
It corrects errors and is parsed.For the simple topic of the answers content such as multiple-choice question, True-False, gap-filling questions, it is only necessary to its result into
Row compares.For needing the topic of user's writing words it is noted that needing the content that parses, such as mathematical computations topic, not only need
Compare its final calculating answer, it is also necessary to compare its specific answer process.
When comparing result is consistent, the expansion for carrying out similar topic parses S452；
Specifically, when comparing result is consistent, illustrate user job be correctly, can be in order to further consolidate study
Carry out the expansion parsing of similar topic or the detailed parsing for remaining solution of the topic.For example, topic information is to count together
Calculation question is learned, comparing result shows that calculating process and calculated result are all correct in the answer content of user, but is directed to this road number
Learn calculation question, also there are many settling mode, wherein also include more succinct calculation method, thus prompt user also there are many
Calculation is simultaneously parsed in detail, so that user be inspired to think deeply, excessively single thinking of solving a problem is avoided to define user's
Thinking and elaborative faculty.
S453 analyzes the answer content for the topic information and whether meets logic when comparing result is inconsistent；
Specifically, not illustrating the certain mistake of user job when comparing result is inconsistent, can only illustrating the answer of user
Content is not identical as Key for Reference, that is to say, that is not consistent with the intention for the people that sets a question, therefore, also needs different situations difference point
Analysis.
Firstly the need of the property for judging topic information, if in operation pictorial information corresponding topic information be multiple-choice question,
The science and engineerings class such as True-False, gap-filling questions, calculation question have the topic of unique correct option, illustrate to use then comparing result is inconsistent
Family operation is wrong.
But if corresponding topic information is the answers such as English Translation or thinking outward bound in operation pictorial information
Not unique topic then comparing result is inconsistent not to illustrate that user job is wrong, but needs further judgement
Whether the answer content of user job meets logic for corresponding topic information in operation pictorial information.
If the S454 answer content meets logic for the topic information, carried out for the topic information a variety of
The parsing of answer mode.
Specifically, being patrolled if the answer content of user job meets for corresponding topic information in operation pictorial information
Volume, then illustrate that the answer content of user is equally correct, therefore the parsing of a variety of answer modes is carried out for topic information, and
The answer content for not denying user directly avoids the thinking elaborative faculty to user from adversely affecting.
For example, a certain road topic information on paper are as follows: mother buys a new writing case to pleasure pleasure and spent 6 yuan 5 jiaos, can be why
Sample is paid, and two kinds of methods of paying please be write out.Answer content to this user is that Alipay and wechat are paid.The answer content of user
With corresponding Key for Reference compare it is inconsistent, but by parsing topic information, it can be seen that combine life in practical situation, use
The answer content at family is actually to meet logic, therefore should not directly determine that the answer content of user is wrong.But it should tie
The situation judgement of the road He Ci topic information is set a question the intention of people, and for example this road topic information appears on paper, it is intended that examines
Core user for the knowledge point of study grasp situation, rather than interest topic carry out thinking expansion.Therefore it is parsed for user
Illustrate that this road topic information herein is the grasp situation in order to examine user to measure coin, then coin is measured and is carried out
Parsing in detail, while also affirming that the answer content of user is correct from the angle of interest.It therefore, is on the one hand user's explanation
On the other hand knowledge point avoids negating directly user, to protect the creativeness of user so that user really understands mistake place
Thinking.
In the present embodiment, not directly using the comparison result of the answer content of user and the Key for Reference of topic as user
The sole criterion of the positive erroneous judgement of operation, but further answer content is parsed when the two compares inconsistent, to protect
Protect the creative thinking of user.
Another embodiment of the invention is the optimal enforcement example of the above embodiments, as shown in Figure 4, comprising:
The operation pictorial information of S100 acquisition user；
S200 identifies that the operation pictorial information obtains corresponding operation type；
S300 selects corresponding review of operations mode according to the operation type；
S400 parses the operation pictorial information according to the review of operations mode, judges correcting errors for corresponding user job
And it is parsed.
