Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
First, applicable scenarios of the embodiments of the present application will be described. The embodiment of the application can be applied to the scene of searching the questions of the lower-grade mathematical oral calculation formula, and the question types of the mathematical oral calculation formula can be analyzed while the correct answers are searched. In the existing scene of searching for questions, usually only searching for questions can be performed to obtain answers to questions and/or analyzing answers to questions, and common methods in the existing scene of searching for questions include AI (Artificial Intelligence) searching for questions, OCR (Optical character recognition) searching for questions, and the like. However, the application of the mathematical oral calculation in the lower grades of primary schools has unique characteristics, for example, the oral calculation formula is simpler, the number of applicable sample texts is less, and the accuracy rate of searching for the problems is low; the calculation formula has many subjects and scenes, including test paper, exercise book and parent's manual. Thus, because the requirement on the question bank is high, and the research and development cost and the material cost are high, the AI search questions cannot be generally applied to the lower-grade mathematical oral calculation. In addition, the conventional OCR search questions are generally applied to the calculation formula of the junior level, but the conventional OCR search questions generally identify the mathematical calculation formula and then return the calculation result or analysis to the user, so that the recommendation capability of other information of the questions is poor, other information such as the question types of the questions are poor, and the question types of the questions have important roles in really understanding and mastering the questions. Therefore, the mathematical oral calculation type question analysis provided by the embodiment of the application can realize the expansion of the question searching function.
Fig. 1 is a flowchart of a mathematical oral calculation type analysis method according to an embodiment of the present invention, which can be executed by a mathematical oral calculation type analysis device implemented by hardware and/or software. Referring to fig. 1, the method may specifically include:
s101, obtaining a mouth calculation formula text.
Taking the mathematical oral calculation in the low-grade exercise book as an example, after a student completes an exercise topic of a certain chapter, completes a job arranged by a teacher, or when the student encounters a topic which cannot be done, parents use topic searching software of electronic equipment to obtain topic answers, topic analysis and topic models so as to better help the child to understand the topic.
Specifically, the text of the search question is acquired through the electronic device, in one mode, the text of the oral arithmetic formula can be directly acquired, and in the other mode, the text can be recognized by acquiring the picture of the oral arithmetic formula. In a specific example, for example, an OCR recognition function of the electronic device is started to obtain a target picture of the target mental arithmetic formula, and OCR recognition technology may be applied to recognize the target picture as mental arithmetic formula text. In one particular example, the electronic device may be a learning tablet or a smartphone, or the like.
S102, identifying operands, operators and brackets in the oral arithmetic expression text.
The whole oral arithmetic formula text comprises operands, operators, "═ and operation results, and whether parentheses are included or not is related to the question types. For example, each operand, each operator and each type of bracket are stored in advance, and since the texts of the three have different characteristics, which texts are operands, operators and brackets in a completed oral arithmetic formula text can be identified. In an actual application process, the operation result is not a requirement for analyzing the topic type, and therefore, the operation result may be identified or may not be identified.
S103, analyzing the question form of the oral arithmetic formula according to the number of operands or operators, the characteristics of the operands, the types of the operators and/or the types and the number of brackets.
The text matching can identify which operands, operators, operation results or brackets of which types are included in the oral arithmetic formula text. For example, four operators of "+", "-", "×" and "+" are stored in advance, and the kind of the operator can be determined by matching the operators in the oral arithmetic formula text to be recognized. Brackets of the type such as "(") "" { "}" "[" ] "are stored in advance, and the type of the brackets can be determined by matching the brackets in the oral arithmetic expression text to be identified. The characteristics of the operands can be realized by analyzing the operands, for example, the characteristics of the operands can be one digit, two digits, three digits, integers of 0, 20 or less, or multiples of ten. Specifically, the classification criteria are different, and the determined dialect formulas are different. For example, a plurality of the same operator may be determined as a consecutive operation, and when the same operator is an addition operator, the operation may be determined as a consecutive operation. For example, if the operands in the modified operation are all multiples of an integer ten, the modified operation can be determined as an integer ten operation.
The technical scheme adopted by the invention has the following beneficial effects: the question model of the oral arithmetic formula is analyzed by acquiring an oral arithmetic formula text and identifying operands, operators and brackets in the oral arithmetic formula text by utilizing the number of the operands or the number of the operators, the characteristics of the operands, the types of the operators and/or the types and the number of the brackets. Accurate judgment of the lower-grade mathematical oral calculation type question types is realized, and when the method is applied to the question searching technology, the operation questions can be known in multiple dimensions, so that parents or teachers can guide students to really understand and master the questions according to the question type characteristics.
Illustratively, the theme of the oral arithmetic formula is analyzed according to the number of operands or operators, the characteristics of the operands, the types of the operators and/or the types and the numbers of brackets, and particularly, the carry analysis in the operation containing addition and the backspace analysis in the operation containing subtraction can be further included.
If the operator comprises at least one addition operator, extracting numbers of corresponding bit positions of two operands participating in the addition operation aiming at each addition operator, respectively adding, judging whether a carry exists or not, and if so, determining the question type of the oral arithmetic formula as the operation with the carry. Specifically, in the lower-level mathematical oral computation, carry and backspace are one of the knowledge points which are mainly studied. In the addition operation, for each corresponding position, for example, the unit digit plus the unit digit is greater than or equal to 10 to indicate that there is a carry, and the tens digit plus the tens digit is greater than or equal to 10 to indicate that there is a carry. For example, when there are two or more addition operators, each group of two operands participating in the addition operation are determined according to the algorithm, and then carry judgment is performed respectively. In a specific example, are 5+6+ 1? If the two operands participating in the addition operation are respectively 5 and 6 for the first addition operator, and the addition result 11 is greater than 10, then carry is judged; for the second addition operator, if the two operands involved in the addition operation are respectively 11 and 1, the ones and tens of the two operands are respectively added to determine whether there is a carry.
If the operator comprises at least one subtraction operator, extracting numbers of corresponding bit positions of two operands participating in the subtraction operation aiming at each subtraction operator, and respectively subtracting to judge whether the operator has a backspace, if so, the problem type of the oral arithmetic formula is the operation with the backspace. Specifically, in the subtraction operation, for each corresponding position, for example, the ones digit of the subtracted number is smaller than the ones digit of the subtracted number, indicating that there is a backspace, and the ten digit of the subtracted number is smaller than the ten digit of the subtracted number, indicating that there is a backspace. For example, when there are two or more subtraction operators, each group of two operands participating in the subtraction operation are determined according to the algorithm, and then carry judgment is performed respectively. In a specific example, 25-7-9? If the two operands participating in the subtraction operation are respectively 25 and 7 for the first subtraction number, the single digit is subtracted, and if 5 is less than 7, the carry is judged, and the calculation result is 18; and for the second reduction number, the two operands participating in the subtraction operation are respectively 18 and 9, the ones digit of the two numbers is subtracted, and if 8 is smaller than 9, the carry is judged.
In addition, the above example is a successive addition or a successive subtraction operation, and if the above example is an addition, subtraction and mixing operation, the determination method is the same, and is not described herein.
Illustratively, the subject of the oral arithmetic formula is analyzed according to the number of operands or operators, the characteristics of the operands, the types of operators, and/or the types and the numbers of brackets, and specifically includes but is not limited to the following analysis.
If the operand is two or the operator is one, the question of the oral arithmetic formula is the basic operation of the question corresponding to the operator. The number of the operands is one more than that of the operators, so if the number of the operands is two or the number of the operators is one, the operation is indicated to be the operation participated by the two operands, and the question is the basic operation. The type of the operator can be continuously judged to determine whether the operator is addition operation, subtraction operation, multiplication operation or division operation; the determination of the characteristics of the operands may also be continued, e.g., whether the operands contain 0, are 1-10, are within 20, are multiples of an integer ten, are three-digit, etc. It should be noted that the judgment criterion may be determined according to the content of the teaching material, for example, if the relevant sections in a certain version of the teaching material have addition and subtraction algorithms within 20, the problem form may be set to have an operand within 20.
If the number of the operands is three or more, the problem of the arithmetic expression is a continuous operation. Wherein if the number of the operands is three or more, indicating that the number of the operators is two or more, the question mark is a continuous operation. Specifically, if the types of operators are the same, for example, if the operators are all addition, the operators are successive addition operation; if the operators are of different types, the question is a hybrid operation. The features of the operands can also be determined, and the question type classification in the continuous operation can be further refined, wherein the feature determination method of the operands can be referred to the foregoing embodiments, and is not described herein.
If the operand contains zero, the question of the oral arithmetic formula is an operation containing zero. The concept of zero is relatively weak to be understood by students in lower grades, and errors are easy to occur in the calculation process, so that whether the operand includes zero can be judged, and if yes, the calculation is zero-containing. Therefore, classification of other layers can be further carried out to determine the question type. For example, if the unit of the number to be subtracted is 0, the teacher or the parents are prompted to see whether the backspace calculation of the question type is wrong or not.
If the operand is a multiple of the integer ten, the problem of the oral arithmetic formula is the operation of the integer ten. If the operand is multiple of the integer ten, the question type is determined to be operation of the integer ten, in addition, the type and the number of operators can be judged, and the question type is continuously refined and classified. For example, an integer-ten addition, an integer-ten subtraction, and the like.
If the characteristics of the operands are different, the characteristics of each operand are determined, and the problem model of the arithmetic expression is an operation corresponding to the characteristics of each operand. The characteristic of the operand is determined, for example, whether the operand contains 0, the operand is 1-10, the operand is 20 or less, the operand is a multiple of an integer ten, the operand is a three-digit number, and the like. It should be noted that the judgment criterion may be determined according to the content of the teaching material, for example, if the relevant sections in a certain version of the teaching material have addition and subtraction calculations within 20, the type may be the operand within 20. In addition, the number and the characteristics of operators can be subdivided to determine the question type.
If the operator type is at least two, the question of the oral arithmetic formula is a mixed operation. Wherein, the type of the operator is judged, and when the type of the operator is at least two, the question type of the oral arithmetic expression is determined to be mixed operation. Optionally, the following cases are specifically included but not limited: if the operator comprises an addition operator and a subtraction operator, the question of the oral arithmetic formula is addition and subtraction mixed operation; if the operator comprises a multiplication operator and a division operator, the topic of the oral arithmetic formula is multiplication-division mixed operation; if the operation symbol comprises at least one of an addition operator and a subtraction operator and at least one of a multiplication operator and a division operator, the oral arithmetic expression is titled as an addition, subtraction, multiplication and division mixed operation. For example, in a mixed operation, the problem types including multiplication and division are classified, considering that the lower-level students have a relatively weak understanding on multiplication and division, and the algorithm is also a knowledge point needing to be mastered intensively, such as first calculating multiplication and division and then calculating addition and subtraction.
If the text of the oral arithmetic formula includes brackets, the topic of the oral arithmetic formula is an operation with brackets. Wherein the parentheses mainly include a small bracket "(" and ")", a large bracket "{" and "}", and a medium bracket "[" and "]". The question type with brackets can prompt a teacher or a parent to notice whether the student notices the existence of the brackets in the process of oral calculation or whether the situation that the calculation error is caused by not seeing the brackets carefully exists. From the perspective of the algorithm, the calculation content in parentheses is calculated preferentially.
Exemplary, also include: if the operator includes at least one multiplication operator, the characteristics of two operands participating in the multiplication operation are judged, and if the two operands are both one digit, the calculation of the operation question type including the multiplication pithy formula is carried out. The corresponding multiplication operation can be further subdivided into a plurality of operation types, wherein two operands participating in the multiplication operation are both one digit, and the operation type is an operation containing a multiplication pithy formula. The question type is helpful for helping teachers and parents to know the mastering conditions of the multiplication pithy formula by students.
For example, if the operand contains zero, the term of the oral arithmetic expression is zero-containing operation, and if the operand contains zero and the operation in which zero participates is multiplication, the term of the oral arithmetic expression is zero-containing multiplication. Specifically, for operations where the operand contains zero, different question types may be determined if the operators are different, with each question type having a different orientation for zero. Wherein, if the multiplication operation involving zero exists, the topic of the oral arithmetic expression is determined as the multiplication operation containing zero. The question type is helpful for teachers to know how students know the knowledge points of zero multiplied by any number. In addition, in the division operation with zero participation, the division operation with zero topic can be determined.
In a specific example, the mathematical expression is 15+78 ═ 93, the matching expression { a } # { b } - { r }, and the matching operator # is + and the operand has a value range of [10,99}, so that the matched problem type is two digits plus two digits. Then, judging whether carry exists, extracting operand units to add 1+7 to 8, less than 10, extracting operand tens to add 5+8 to 13, more than 10, and determining that carry exists, then judging the question type to be a two-digit-plus-two-digit operation with carry. Illustratively, fig. 2 shows a display page diagram of a question type analysis result, fig. 3 shows a display page diagram of a question type analysis detailed solution, and clicking an icon of the question type analysis detailed solution in fig. 3 can jump to the display page of the question type analysis detailed solution in fig. 3.
It should be noted that the classification of the question type has no unique standard, and the classification can be specifically carried out according to the error frequency of students or knowledge points in the teaching outline; furthermore, the same question type may be classified according to the features of the operands, or according to the types or features of the operators, or both, and the obtained question type determination result may be different, and some question type may include another question type, for example, the successive question type includes 20 or less successive question types. Accordingly, the above-described topics are merely illustrative and not intended to be limiting.
In practical applications, more detailed themes may include: 1-10 addition or subtraction, addition or subtraction with zeros, successive addition or subtraction, addition and subtraction mixing, addition and subtraction of tens and tens, addition and subtraction mixing of 20 or less, subtraction within 20, integer addition or subtraction, two-digit addition and subtraction, integer tens, addition and subtraction mixing or successive subtraction including brackets, two-digit addition and two-digit operation without carry, two-digit addition and two-digit operation with carry, two-digit subtraction and two-digit operation with subtraction, operation including multiplication pithy, multiplication or multiplication and subtraction, operation using multiplication pithy formula of 2-6, addition and subtraction, multiplication and division mixing, operation with hundreds of tens and hundreds of tens, three-digit addition and two-digit or three-digit operation, three-digit subtraction without subtraction, three-digit subtraction, operation with addition and subtraction, The operation of subtracting two digits from three digits of the setback, the setback subtraction with zero in the middle of the subtracted number, the operation of checking the subtraction by using the subtraction, the operation of multiplying one digit by zero, the operation of multiplying one digit or two digits by three digits, the division operation with the divisor being two digits, and the like. Different analysis criteria or analysis conditions may be applied to analyze or determine the topic.
In a specific example, table 1 shows a profile feature table, where { a }, { b }, and { c } indicate corresponding operands, # indicates an operator, and { r } indicates an operation result; { + }, { - }, { × }, { + } or { + } represents operators; i represents or; and & represents and; the maximum operand is the maximum value in the operands; the minimum operand is the minimum value in the operands; true indicates yes and false indicates no.

It should be noted that, due to space limitations, table 1 is shown in two pages, which are actually the table contents in table 1.
