Description

A kind of exam paper marking system

Technical field

The present invention relates to multimedia teaching fields to relate in particular to one kind more particularly to a kind of exam paper marking system The exam paper marking system of electronic test paper for multimedia teaching.

Background technique

Known, the examination that early stage carries out generallys use the mode for teacher's group signature of going over examination papers, and the teacher that gos over examination papers is straight by score It connects and is labeled on paper, after the completion of waiting all papers to correct, united again by manually copying score in summary Meter analysis.This craft mode of going over examination papers be it is very original, working efficiency is low, and achievement transcribing errors are also inevitable, is only suitable for Minimum scale and the insignificant examinations such as class, grade's examination.

With the development of science and technology gradually proposing the concept that automation is goed over examination papers.Mode known to a kind of is by using mark Remember the automatic scoring that paper carries out, or passes through image procossing as disclosed in Japanese documentation JP-A-7-199794 Device scores to answer sheet, is configured to described image processor to come distinguished symbol and mark by using Digital Image Processing Remember and these symbols and label are compared to score to answer sheet with correct option.And such as in Japanese documentation Disclosed in JP-A-11-224245 like that, where it is proposed such a points-scoring systems, and the system is configured to by making With special-purpose cushion and pen and detects the state of pen automatic scoring is carried out to answer sheet.

However, the above-mentioned prior art has the disadvantages that.That is, institute is public using mark sheet and in JP-A-7-199794 In the case that the image processor opened carries out automatic scoring, if answer and is-not symbol, character or label by text (as answered The problem of), then answer cannot be identified by answer recognition unit, therefore cannot score answer.Further, since will Points-scoring system disclosed in JP-A-11-224245 is configured to by using special-purpose cushion and pen and detects the state of pen and come to answer Paper carries out automatic scoring, it is therefore desirable to the specialized hardware of such as special-purpose cushion and pen, therefore its structure becomes complicated and expensive.

With the further development of computer networking technology and image processing techniques, automation, which is goed over examination papers, to be further evolved into Using computer marking.Computer marking is carried out by the way of paper and test paper separation, and objective item is appraised automatically by computer, Subjective item on computers scores respectively to the electronic image of examinee's test paper by network by the different teachers that gos over examination papers, finally Carry out core point and achievement verification automatically by computer system again.The teacher that marks examination papers can be effectively prevented using computer network grading Between influence each other, moreover it is possible to the error rate that will go over examination papers minimizes.Current is all utilized in for computer marking system Anchor point is set on answering card, and the answer sheet recognition device of computer marking system is identified by induction on special answering card Anchor point identifies different topic answer locations.As an example, a kind of calculating is disclosed in CN101866415A The answer sheet recognition device of machine marking system, including data read module and character recognition module, wherein the reading data mould Block is sent to the character recognition module for obtaining answer sheet picture information, and by the answer sheet picture information；The word Identification module is accorded with, for using optical character recognition technology, the character shape of the answer sheet picture information is translated into calculating The readable text information of machine and storage.As another example, a kind of examination based on OCR identification is disclosed in CN102890775A Score automatic identification processing method is rolled up, including the marking region on automatic program identification paper, is identified and is tried using OCR technique Roll up score.Directly the hand-written score on papery paper is handled in above-mentioned document, does not need to make dedicated answering card.So And in practice, it has been found that can only enough meet that there are the objective items of model answer (such as to select using optical character recognition technology Select topic, True-False etc.), but for needing then still obviously not accurately identifying and sentence come the topic of answer using character express It is disconnected.

It is also used as another example, a kind of terminal examination evaluation system, the system packet are disclosed in CN104900101A Include server, student terminal system and the teacher's terminal system that interaction is realized by internet, wherein contain in server memory Exam pool and exam pool answer, the server send operation topic and examination paper according to the examination order that teacher's terminal system is issued To aobvious outside student terminal system, and input student's answer in student terminal system by user, then on pass server back, service Device receives student's answer and is read and made comments according to exam pool answer, then will read and make comments result and be sent to examination terminal system and student terminal system System.The system can be realized Automatic Read Overmarginalia, and provide go over examination papers speed and quality of instruction.Then, the system is not first still The topic that answer is literal expression can be read and made comments.Further, it is difficult to ensure due to automating the quality read and made comments, in the essence read and made comments Real needs are not able to satisfy in terms of exactness and accuracy.

As an improvement example, a kind of teaching machine based on electromagnetic handwritten plate is disclosed in CN106887168A Network on-line teaching system, including teacher's terminal and student terminal include to read and make comments module in teacher's terminal, described to read and make comments mould Block includes reading and making comments module and Automatic Read Overmarginalia module manually.It is described manually read and make comments module for teacher manually to student reply content into Row verification, Automatic Read Overmarginalia module are that system automatically replies student and answer compares verification.Specifically, using including original Handwriting recognition module and speech recognition module acquire the voice of person's handwriting and microphone or microphone of the handwriting pad with time writer, logical It crosses data processing module the reply message of identification is compared with correct option and go over examination papers.Manually read and make comments module be then used as it is auxiliary It helps and student's answer content is checked manually for teacher.Although introduced in the document manually read and make comments module for into Capable verification, but the hardware that the actually described system itself is inputted is prohibitively expensive, and for oneself of person's handwriting and voice It is dynamic to read and make comments the topic for being inherently unable to satisfy and reading and making comments that answer is literal expression, therefore the system is still unable to satisfy real needs.

As a kind of trial of the automatic marking processing to character property examination question, by Iflytek limited liability company as Shen A kind of answer recognition methods and system for character property examination question, the method packet are disclosed in the CN104463101A to ask someone It includes: obtaining character property script image；One or more answer character strings to be identified are obtained from the answer image；It is based on General acoustic model carries out handwriting recognition to the answer character string to be identified, obtains the first recognition result；Obtain character property The answer information of examination question；According to the answer information of first recognition result and the character property examination question, adaptive acoustic is constructed Model；Handwriting recognition is carried out to the answer character string to be identified using the adaptive acoustic model, obtains finally identifying knot Fruit.By above technical scheme, the recognition accuracy of character property objective item can effectively improve, and then improve go over examination papers efficiency and standard True property.

However, above paper automatic marking processing system do not meet the teacher that gos over examination papers in practice read and make comments habit, exist Human-computer interaction is poor, read and make comments process design with actually go over examination papers habit be separated the case where, the effect of actual use can not make us full Meaning.Further, in actually examination test, paper is different according to the subject test or field and generally comprises different topics Type, such as examine in and must examine subject with college entrance examination: for Chinese language and foreign language, it is indispensable can there are problems that for example, fill, Or the topics type such as discussion topic.The feature of reading and making comments of these topic types is: 1. and be not present no model answer, and be usually by multiple keys Key for Reference composed by word (so-called to branch or adopt branch)；2. fixed format is often not present in the result of answering of student And template, there are very big othernesses, there is a situation where following such: although the result of answering of student is stating upper and standard Answer is different, but has actually grasped key answering principles substantially, at this time often according to stringent comparison in the prior art It is judged as mistake, makes the accuracy of test by serious influence；3. read and make comments paper, in addition to needing to provide examination Outside score, it is also desirable to retain the trace of reading and making comments for the teacher that gos over examination papers, such as teacher is for the note of student's answer and comment etc., So that student is it will be appreciated that the shortcoming of itself, while it also can satisfy the needs that teacher comments on paper.

Applicant it is hereby stated that, what is stated in above section is only the technology contents that are known of applicant.Above content is only Provide only the prior art for being related to the relevant background information of the disclosure but not necessarily constituting the application.

It is that present multimedia tutoring system is opened in consideration of it, how to provide a kind of exam paper marking system to meet current demand Originator problem anxious to be resolved.

In a specific embodiment of the present invention, the electronic test paper includes at least one quiz, and the above quiz is selected From in quiz stored in paper database 31, naturally it is also possible to it is envisioned that can also be by server 30 from paper database Different quizs is selected in 31 to form the electronic test paper.Here, at least one test question in the electronic test paper is excellent Selection of land includes objective item and subjective item two types.Wherein, in the present invention, term " objective item " refers to the test The topic type of the model answer of topic, the result of the topic type read and made comments only include two kinds of answer right and wrong as a result, as non-limit Qualitative example, the topic type be for example non-topic, multiple-choice question, choose topic etc..Meanwhile " subjective item " refers to reference at least one example The Key for Reference of for example character property gives the topic type read and made comments with certain subjectivity, wherein the Key for Reference for example can be by more A keyword (i.e. so-called to branch or adopt branch) composition, wherein the result read and made comments may comprising answer correct, mistake with At least three kinds of unknown (can not judge whether correctly or incorrectly) etc. as a result, as non-limiting example, the topic type is for example It is simple answer, Essay Writing topic and gap-filling questions etc..

Referring next to Fig. 1, via the aobvious electronic test paper from server 30 outside the first display module 102 and take one's test Student can be via the first input module 101 existing comprising subjective item and objective item to electronic test paper of the first terminal equipment 10 Interior quiz is answered and answer result is uploaded to server 30, and then, the first of server 30 reads and makes comments module 301 can According to the Key for Reference for corresponding to each quiz, the comparison of Lai Jinhang answer result, and then obtains and tentatively read and make comments result.

In the present invention, the answer of quiz can be also stored in paper database 31 with each quiz, in the present invention Specific embodiment in read and make comments module 301 by tentatively read and made comments automatically first and read out, according to each quiz by participating in Quiz answer given by the student of test as a result, first read and make comments module 301 automatically read and make comments the student that takes one's test to Whether the answer result of each quiz out is correct.The process of Automatic Read Overmarginalia according to the present invention described in detail below: it is taking First in business device 30 reads and makes comments complete comparison unit 3011 of the module 301 with complete comparing function and there is character string to compare The character string comparison unit 3012 of function.

Fig. 2 is referred to, wherein Fig. 2 is to schematically depict the according to the present invention first composition for reading and making comments module 301.Such as Shown in Fig. 2, described first, which reads and makes comments module 301, further includes complete comparison unit 3011, character string comparison unit 3012.Below By English test electronic test paper for, quiz can be roughly divided into have appraise according to model answer go over examination papers it is objective Topic, and with subjective item both topic types goed over examination papers of taking the circumstances into consideration appraise according to Key for Reference, wherein have according to reference to answering Case is taken the circumstances into consideration appraise the subjective item goed over examination papers, and the whether correct judgment mode of answer has certain fuzzy space.Citing and Speech, for the topics type such as simply inscribing, Key for Reference is often made of multiple keywords (i.e. so-called to branch or adopt branch), Even if the answer result of the student to take one's test is above not quite similar with Key for Reference in answer statement, if but having contained described It is multiple to branch or to adopt branch, and state upper logical, can be considered that answer is correct, even if answer statement may with answer It is very big to inscribe result gap.

According to a particular embodiment of the invention, complete comparison unit 3011 is used to compare answering for the objective item in each quiz Topic as a result, and generate correspond to objective item accurately read and make comments result, wherein the objective entitled topic type with model answer, Such as the objective entitled single choice, as long as having read the option information that the student that takes one's test is chosen, by the option information Whether answer correct with the scheduled model answer test question that compares that you can get it and gives corresponding score, subsequent institute The score for stating objective item will be sent to fractional statistics module 302.

Further, for the answer of character property objective item, due to the student that takes one's test knowledge point grasp ability and Without fixed format, the answer result for being input to character string comparison unit 3012 exists for the difference of answer level and answer itself The different situation of answering mode.It really may be implemented accurately to automate using character string comparison progress operation and go over examination papers, but count Calculation amount is still excessive, therefore has and advanced optimize to promote the room for improvement of operation efficiency.

As more preferred mode, in electronic test paper, the character string comparison unit 3012 will take one's test student Answer result compared with Key for Reference obtain the subjective item about the test tentatively read and make comments as a result, and described Indicate the error degree with Key for Reference in answer result respectively in different colors.Specifically, test student is first checked for Answer as a result, differentiating sentence paragraph using comma or fullstop to form multiple character strings, then by the multiple character string Transcription comparison is carried out with the character string of Key for Reference to read and make comments, when answer result is clearly present error with Key for Reference, depending on It for answer apparent error, will be shown with red-label, conversely, when not having obvious errors, it is correct to be considered as answer, will be shown with Green Marker Show, to can not judge whether correctly or incorrectly to indicate with yellow.It is described in detail below with reference to preferable example.

Still by taking English letter answer as an example, as shown in figure 3, the character string comparison unit 3012 includes: the first conversion submodule Block 321, for the character string of multiple character strings of the answer result for the student that takes one's test and the Key for Reference of subjective item will to be used as It is converted into word sequence respectively；Second transform subblock 322, for word sequence to be converted into corresponding set of words respectively；First fortune Operator module 323, the min-hash distance between minimum hash and set of words for calculating each set of words；Classification submodule Block 324, for being classified according to min-hash distance to word sequence；And the second operation submodule 325, in same class In carry out shared string operations.It should be pointed out that in the complete comparison unit 3011 and character string comparison unit 3012 Each functional module being implemented in combination with by hardware, software or hardware and software, thereby executing following according to this hair Bright method and steps.

In the present invention, " word sequence " refers to the sequence of word；Correspondingly, " set of words " refers to the set of word.In other words, sequence Column and the constitution element of set are all words.The difference of the two is that the element in sequence can repeat and must have sequentially, and Order of elements is not considered in set and element is without repetition.As an example, for example, test student submit answer result word Symbol string are as follows: " the Chinese nation gets the great rejuvenation "；At the same time, the word of Key for Reference Symbol string is " the great rejuvenation of the Chinese nation ".So, as shown in figure 4, first in step The word sequence A for obtaining the character string of answer result after the participle operation of the first transform subblock 321 in rapid S100 are as follows: { the, Chinese, nation, gets, the, great, rejuvenation }.The character string of Key for Reference is by the first conversion Keyword word sequence B:{ the, great, rejuvenation, of, the obtained after the participle operation of device 321, Chinese, nation }.Certainly as known to those skilled in the art, character string of the invention is right not only just for English word It also can be all applicable in the mixed word etc. of the word or Chinese and English of Chinese.

It in the present invention, then in step s 200 can be by the more of the second transform subblock self-test in 322 future student The word sequence of the Key for Reference of a answer result and the subjective item is converted into corresponding set of words, in conversion process, weight Existing word of appearing again only retains one, such as " the ".To make above example convert after obtain set of words A the, Chinese, nation, gets, great, rejuvenation }；Set of words B be then the, great, rejuvenation, Of, Chinese, nation }.

Then, each of the above set of words is calculated using hash algorithm by the first operation submodule 323 in step S300 Minimum hash, the minimum hash can be used for calculating the Jaccard similarity between two set of words.Those skilled in the art Member knows that so-called Jaccard similarity refers to for two set A, B, then Jaccard (A, B)=| A ∩ B |/| A ∪ B |.? On the basis of this, the first operation submodule 323 calculates the set of words for each answer result that test student submits and subjective item refers to The set of words of answer two-by-two between min-hash distance.In the present invention, minimum hash is the numerical value (such as 32 of regular length Position).In this 32, position is identical and the number for the position that numerical value is different is the min-hash distance between two set of words, For middle min-hash apart from smaller, the Jaccard similarity of the two set of words is higher.By the min-hash distance being calculated with Preset first threshold is compared, and min-hash distance is less than word order corresponding to the set of words of the first threshold Column are classified as same class, and in the present invention, as non-limiting example, the first threshold can be the digit of minimum hash 50%.Certainly, those skilled in the art, which can according to need, sets the threshold value, this is understood that obtain.

Then, in step S400, in multiple answer results for submitted the student to take one's test by classification submodule 324 , the word sequence for meeting min-hash distance in the word sequence being converted into and being less than this condition of first threshold remain, it is right In being unsatisfactory for answer of the min-hash distance less than this condition of first threshold, the answer result of student's input can be considered as Completely and the keyword (i.e. point scoring or adopting branch) of Key for Reference is dissimilar or not approximate, therefore character string comparison unit The answer result of the student is directly automatically judged to answer apparent error and is indicated with red-label and be sent to the by 3012 Two display modules 202, and the test question is not given point or the information of score is not sent to fractional statistics module 302.It is right In the word sequence for meeting min-hash distance condition, its word sequence corresponding with Key for Reference is divided into a class.

Finally, in step S500, by the second operation submodule 325 arbitrarily selected from above same class one as The word sequence of student's answer result and the word sequence of Key for Reference carry out the operation of shared character string.Below to belong in same class A student the word sequence of answer result and the word sequence of Key for Reference for carry out shared character string Calculating process.For simplicity by above English word respectively with the schematical mark of letter.

In the first situation, it is assumed that the word order of student's answer result is classified as { A, B, A, D, E, F, G }, the word of Key for Reference Sequence is { A, B, B, D, E, F, G }.By sharing string operations, the word sequence of student's answer result and the word order of Key for Reference The shared character string of column is { A, B, D, E, F, G }, length 6.Since the length of the word sequence of Key for Reference is 7, it is known that shared The lenth ratio of the word sequence of string length and Key for Reference is greater than preset threshold value (such as 80%).In this case, Can be considered as student input answer result it is identical with keyword (i.e. point scoring or the adopting branch) of Key for Reference or Person is completely approximate, and it is obvious correct simultaneously that the answer result of the student is directly automatically judged to answer by character string comparison unit 3012 And the word order of student's answer result is classified as outside { A, B, A, D, E, F, G } progress and shows and is included by shared character string therein Character shown with Green Marker and be sent to the second display module 202, further also the corresponding score of the test question is believed Breath is sent to fractional statistics module 302.

In another case, assume that the word order of student's answer result is classified as { A, B, A, D, E, F, G }, the word order of Key for Reference It is classified as { A, B, B, C, E, F, G }.By sharing string operations, the word sequence of student's answer result and the word sequence of Key for Reference Shared character string be { A, B, E, F, G }, length 5.Since the length of the word sequence of Key for Reference is 7, it is known that shared character The lenth ratio of the word sequence of string length and Key for Reference is less than preset threshold value.In this case, character string comparison unit 3012 it is considered that the answer result of student input and keyword (i.e. point scoring or adopting branch) part phase of Key for Reference Same or part is approximate, i.e., the answer result of the described student belongs to the scope that can not judge whether correctly or incorrectly.In this feelings Under condition, by the word order of student's answer result be classified as { A, B, A, D, E, F, G } carry out it is outer aobvious and by shared character string institute therein The character for including shows with yellow flag and is sent to the second display module 202, and the score of the test question half is believed Breath can be sent to fractional statistics module 302.

From the foregoing, it will be observed that complete comparison unit 3011 and character string comparison unit 3012 in module 301 are read and made comments by first, Can be realized to automatically, rapidly answer to the student that takes one's test to electronic test paper the case where read and make comments, wherein for visitor Sight topic can accurately provide score, and for subjective item, preliminary screening can be provided according to answer situation and is criticized for the first time Read as a result, and the answer result for the student that takes one's test is marked with different colors, thus go over examination papers religion convenient for the later period Teacher's finally reads and makes comments work.Further, according to the preferred embodiment of min-hash algorithm utilized above, with unused min-hash The character string comparison unit of algorithm is compared, and can rapidly be judged between answer result and Key for Reference with the presence or absence of apparent poor It is different, so as to be effectively saved the calculation amount of character string comparison operation and the calculation resources of occupancy.

From the above, in the present invention, finally reading and making comments work includes finally reading and making comments work and to student to subjective item The note of answer and annotation, and retain reading and making comments to show outside trace and checking to the student to take one's test for the teacher that gos over examination papers.Specifically For, as shown in Figure 1, the teacher that gos over examination papers can log on server 30 via second terminal equipment 20, utilize the second input module 201 and second read and make comments module 112 to read and make comments for the first time result and first read and make comments the score that module 301 provides read and made comments again and It obtains and finally reads and makes comments result.In the present invention, finally reading and making comments result may be that first read and make comments in result of modification is judged for example The answer of subjective item whether review again correctly or incorrectly, can also be to be criticized to the answer result and thinking of each subjective item Note, naturally it is also possible to be that amendment first reads and makes comments the score that module 301 provides to generate and finally read and make comments as a result, can also further incite somebody to action It is stored in server 30 with the electronic test paper for finally reading and making comments result and/or answer annotation for the reading of first terminal equipment 10 It takes.Specifically, go over examination papers teacher by the answer result of each subjective item again row check correct or annotate after finally read and made comments As a result, therefore, the recycling first terminal equipment 10 of the student to take one's test logs on server 30, and via the first display mould Block 102 shows annotation given by result (containing the electronic test paper for finally reading and making comments score) and the person of going over examination papers after reading and making comments.

In the present invention, second input module 201 is preferably the handwriting input trace that can recorde the teacher that gos over examination papers Hand-writing recognition unit 201.In the present invention, the hand-writing recognition unit 201 of adaptation is selected according to the type of server 30.Tool For body, when server 30 is desktop computer, the hand-writing recognition unit 201 can utilize wired mode (such as USB connection Line) or wireless mode (such as infrared ray, bluetooth, WiFi, NFC wireless communication technique) with as desktop computer server into Row communication connection, and in the case, the hand-writing recognition unit 201 can be selected from handwriting pad, photography assembly or electronic pen etc. Has the handwriting recognition component of handwriting record and discriminating function.Further, the hand-writing recognition unit 201 preferably has memory Function is for storage handwriting recognition data.At the same time, when second terminal equipment 20 is movable termination, for example, smart phone Or when tablet computer, the hand-writing recognition unit 201 can use the capacitive touch sensors of the movable termination with And matched handwriting recognition engine, i.e., religion of going over examination papers directly is recorded in the sliding of the mobile terminal by the finger of the teacher that gos over examination papers The handwriting input trace of teacher.Then, divide the handwriting input trace and by handwriting recognition engine identification character to be transmitted to screen Curtain carries out outer aobvious.

In a preferred embodiment, by way of the shared string operations in character string comparison unit 3012 Through the Key for Reference of the answer result for the student that takes one's test and each subjective item has been carried out preliminary comparison.For via character Correct answer of the comparison unit 3012 labeled as the complete wrong of red and labeled as green go here and there as a result, going over examination papers teacher at this time only It needs to operate hand-writing recognition unit 201 to add their confirmation to the result of going over examination papers of character string comparison unit 3012.At this time due to religion of going over examination papers Teacher only needs substantially to browse can be confirmed by the requirement whether answer of the part of Green Marker has met Key for Reference, To greatly reduce the labor intensity for the teacher that gos over examination papers.Further, it is answered for what label in the second display module 202 was Topic as a result, the teacher that gos over examination papers can annotate answer result according to answer situation, such as in simple topic in label with it is described Related source of the relevant knowledge point of problem to the knowledge point in textbook, above information can be led to by the teacher that gos over examination papers It crosses hand-writing recognition unit 201 to be input in server 30, and is further used as additional information storage into electronic test paper.

The answer for being for the label that can not judge whether correctly or incorrectly is as a result, the teacher that gos over examination papers needs emphasis to be subject to It reads and makes comments.When reading and making comments, exam paper marking system of the invention can assign the teacher that the gos over examination papers permission for reading and making comments the subjective item again.Tool For body, exam paper marking system of the invention is that per pass subjective item is equipped with score upper bound belonging to it, for example, per pass letter answer Score upper bound be 10 points.Label correctly or incorrectly, which is, to be judged whether for those character string comparison units 3012 Answer as a result, being taken the circumstances into consideration in the score section of 0-10 point by going over examination papers teacher according to Key for Reference to be given a mark and/or write batch Note.When exam paper marking system discovery is greater than 10 via the fractional value that the teacher that gos over examination papers that hand-writing recognition unit 201 inputs provides, institute It states exam paper marking system and forbids the operation from second input equipment 20 and sending " can not operate " or " beyond score The warning of the upper limit ", to prompt to go over examination papers, teacher does not meet pre-defined rule to score value for the simple answer.Via to per pass subjectivity Topic is equipped with score upper bound, so that the teacher that gos over examination papers will not be goed over examination papers work and mistakenly assert the class due to heavy The upper limit score value of subjective item, thus maximum likelihood avoid the teacher that gos over examination papers subjective a possibility that making a mistake.

It is further preferred that in order to improve the speed and that retains the teacher that gos over examination papers go over examination papers trace for example of going over examination papers for the teacher that gos over examination papers Point comment or annotation need to effectively improve in the writing input efficiency and stringent identification for example, of hand-writing recognition unit 201 The input method of the character of text, therefore input method hand-written it is preferable to use reduplicated word in the present invention, this input method are to allow For user after writing a character, the character late of handwriting input can fold the handwriting input for writing on the top of first character Method.The hand-written input method of reduplicated word according to the present invention, go over examination papers teacher can in the useful space of handwriting input any position It sets and carries out continuous handwriting input, to more be bonded the habit of going over examination papers for the teacher that gos over examination papers.

Specifically, hand-writing recognition unit 201 of the invention is configured to allow go over examination papers teacher uninterruptedly carry out it is any number of Character continuous hand-written simultaneously carries out corresponding identifying processing, to effectively promote the efficiency for writing input.It below will be by readding It is that example describes this hair come the handwriting input trace for recording the teacher that gos over examination papers that the finger of teacher, which is rolled up, in the sliding of the mobile terminal The hand-written input method of bright reduplicated word.Certainly, as known to those skilled in the art, the hand-written input method of above-mentioned reduplicated word is similarly Suitable for carrying out handwriting input in a manner of writing pencil and this mode should also be as being considered as claimed content.

The hand-written input method of the reduplicated word of multiword symbol continuous writing according to the present invention, is detected by hand-writing recognition unit 201 The different strokes of first character and second character out, when the teacher that gos over examination papers starts to fold and writes second character, preferably automatically The display color for having write the first character finished is dimmed, to facilitate the teacher that gos over examination papers from 202 supernatant of the second display module The trace of the current character of oneself institute's handwriting input is seen clearly.It can not stop in this way and continuously arbitrarily write multiple words Symbol.It is when handwriting input third character, the viewing area of the first character inputted before from the second display module 202 is automatic It disappears, and second character inputted before being allowed to is automatically dimmed, thus realizes final continuous formality input, it below will be specific Introduce each step of the method:

Go over examination papers first teacher finger contact in the present invention be, for example, touch screen the second display module 202, start it is defeated Enter stroke, at this moment hand-writing recognition unit 201 can be detected finger contact this event of touch screen, start recording go over examination papers teacher input Character stroke person's handwriting.Next, the hand-writing recognition unit 201 records religion of going over examination papers when finger moves on the touchscreen The handwriting input trace of teacher, and transfer handwriting area on the touchscreen and show corresponding stroke track, this embodiment it In, the stroke color of current hand-written character is indicated with red；(as known to those skilled in the art, it is also possible to which other color expression is worked as The color of preceding handwritten stroke, red are intended merely to be more in line with the habit of going over examination papers for the teacher that gos over examination papers, and replace the color of handwritten stroke simultaneously The substantive content of the content of present invention is not influenced)；The teacher that gos over examination papers keeps handwriting input until its finger leaves touch screen, current stroke End of input.

Then, hand-writing recognition unit 201 judges whether the stroke of current handwriting input belongs to the stroke inputted before In the same character.Specific decision logic and method are as follows: either Chinese Hanzi character or English word character, stroke Input is all sequence from left to right, such as is usually the combinde rqdical character of tiled configuration in chinese character, wherein left side is needs The radical first inputted.Based on this discovery, the stroke for judging current handwriting input of the application and the stroke inputted before Whether first criterion of same character is belonged to are as follows: judges whether current stroke is newly to write pen on the right side of preceding unicursal It draws, if it is determined that being that stroke is write in the new of right side, it may be considered that stroke currently entered and the stroke inputted before are to belong to In the same character.If it is determined that being not located at the right side of preceding unicursal, then in view of certain Chinese characters are, for example, up-down structure Combinde rqdical character, such as " basin " word are made of " being divided to " and " ware word bottom " two radicals, then carry out the judgement of Second Criterion condition: judgement is worked as Whether preceding stroke, which is folded on trace with the stroke of handwriting input before, is write, if not folded on trace write, can be recognized It with the stroke before inputted is to belong to the same character for stroke currently entered.If it is determined that current stroke is therewith The stroke of preceding handwriting input on trace fold writes, then carry out the judgement of third criterion: judge current stroke with it is hand-written The folded of the stroke of input writes degree, writes degree less than 60% if folded, it may be considered that stroke currently entered with before The stroke of input is to belong to the same character., whereas if folded degree of writing is greater than 60%, it may be considered that stroke currently entered It is to be not belonging to the same character with the stroke inputted before.

Then, judge that the stroke that stroke currently entered has been inputted with before is to belong to together in hand-writing recognition unit 201 In the case where one character, further determine whether that there are also new strokes to input, if there is also have new stroke input, institute The handwriting input trace that hand-writing recognition unit 201 persistently records the teacher that gos over examination papers is stated, and handwriting area always on the touchscreen is aobvious Show corresponding stroke track, until to show that stroke currently entered no longer belongs to the stroke inputted before same for judgement The handwritten traces of current record write are carried out Text region at this time, and export recognition result on the touchscreen by character, so Recognition result is subjected to dimmed processing afterwards.

Meanwhile if judging that the stroke that stroke currently entered has been inputted with before does not belong in hand-writing recognition unit 201 In the case where the same character, then judging, which whether there is on touch screen, has write and had carried out identifying processing and become The hand-written character of dark treatment, if having had existed such hand-written character, by the word for having carried out identifying processing Symbol is eliminated.Continue by other than current stroke all strokes constitute a handwriting characters, carry out Text region and Recognition result is exported on touch screen, and recognition result is then subjected to dimmed processing.

It can be seen that the input method hand-written via reduplicated word of the invention, so that the teacher that gos over examination papers carries out book on the touchscreen When writing, continuous reduplicated word handwriting input is carried out according to the habit that the teacher that gos over examination papers writes naturally, it can be continuous hand-written defeated incessantly Enter multiple texts, the handwritten traces that hand-writing recognition unit 201 automatically inputs the teacher that gos over examination papers carry out identification output, thus effectively The efficiency for improving handwriting input.

On this basis, read and make comments the operation at module 303 second via teacher is goed over examination papers, can to tentatively go over examination papers result and The score being stored in fractional statistics module 302 is read and made comments again and is obtained and finally read and made comments result and go over examination papers given by teacher Annotation.The recycling first terminal equipment 10 of the student to take one's test as a result, logs on server 30 and is read and made comments with reading second Information above in module 303, and finally reading and making comments after reading and making comments is shown to the student to take one's test via the first display module 102 As a result (contain the electronic test paper for finally reading and making comments score) and the teacher that gos over examination papers given by annotation.

To sum up, exam paper marking system according to the present invention can first be answered with standard by complete comparison unit 3011 The answer result of the objective item of case is strictly compared, and via character string comparison unit 3012 to by multiple crucial phrases At the answer result that provides of student of subjective item of Key for Reference compare, thus tentatively goed over examination papers result and its point Number, at the same the answer result of subjective item is indicated according to different situations with different colors and show answer result with Shared character string between Key for Reference.Then, going over examination papers teacher can be to tentatively going over examination papers result and its score is read and made comments again, example Such as is checked, is confirmed, modified or marked in detail to Key for Reference or the subjective item compare, thus It obtains finally to read and make comments result and be back to outside first terminal equipment and show to the student to take one's test.Via automatically to objective item progress It compares completely, and the mode that shared character string is compared and indicated is carried out to subjective item, the labour that can reduce the teacher that gos over examination papers is strong Degree also takes into account the accuracy goed over examination papers simultaneously.
