To facilitate understanding of the present embodiment, a problem solving presentation method disclosed in the embodiments of the present disclosure is first described in detail, and an execution subject of the problem solving presentation method provided in the embodiments of the present disclosure is generally a computer device with certain computing capability, where the computer device includes: a terminal device, which may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle mounted device, a wearable device, or a server or other processing device. In some possible implementations, the problem solving presentation method may be implemented by a processor calling computer readable instructions stored in a memory.
The following describes the problem solving demonstration method provided by the embodiment of the present disclosure by taking the execution subject as the terminal device.
Referring to fig. 1, which is a flowchart of a problem solving demonstration method provided in an embodiment of the present disclosure, the method includes steps S101 to S104, where:
s101, obtaining the problem to be solved.
The problem to be solved can be a mathematical calculation problem and can be composed of elements such as numbers, operation symbols, unknowns and the like. Such as "99 + 36", "(5 × 67+4) ÷ 7", "x +79- (x × 7) ═ 161", etc., the object to be solved may be a four-rule mixing operation, a solution equation, etc.
In one possible embodiment, obtaining a subject to be solved includes:
acquiring a shot image of a subject to be solved;
and extracting text contents in the image of the problem to be solved to obtain the problem to be solved.
Illustratively, an image recognition technology can be used to recognize a topic area in an image of a topic to be solved, and then a text recognition technology is used to extract text contents of the topic area to obtain the topic to be solved.
In one possible implementation, the problem solving presentation method further includes:
and determining the attribute information of the title to be solved according to characters and operators in the text content of the title to be solved.
Here, the topic attribute information may refer to characteristics of the content of the topic to be solved on characters and operators, such as: the total amount of the number to be operated in the question to be solved, the combination mode of the operation symbol and the number, whether the power symbol exists, and the like.
S102, determining a problem solving method according to the problem attribute information corresponding to the problem to be solved.
In this step, the topic to be solved may have a plurality of topic attribute information. The topic attribute information can include the type of expression (addition, subtraction, multiplication, division), the number of bits of operation (e.g., three-bit operation, four-bit operation), etc. in the topic.
In general, the problem solving method can refer to mathematical methods that can be used for solving the problem to be solved, such as iterative calculation (discrete calculation), vertical calculation, horizontal calculation, etc., and these higher-level problem solving methods are further divided into a plurality of secondary problem solving methods, such as addition vertical calculation, subtraction vertical calculation, multiplication vertical calculation, division vertical calculation, etc., and the secondary problem solving methods also include more secondary problem solving methods, such as two-number addition vertical calculation, three-number addition vertical calculation, etc., until the final problem solving method, and the problem solving method determined in this application is the final problem solving method described above.
Furthermore, what solving method is used for solving the problems is closely connected with the problems, when the attribute information of the problems meets certain conditions, a specific problem solving method can be used, for example, the vertical calculation condition is "three or more decimals or integer continuous addition", the iterative calculation condition is "at least 3 numbers are operated", and the attribute information of the topic "12 +13+ 14" includes "three integers are added" and "three numbers are used for operation", the topic can be calculated by using a vertical calculation and a recurrence equation, the title attribute information of the title also comprises 'three-number addition', and under the problem solving method of vertical calculation, the problem solving method of vertical calculation can also be utilized, so that, and determining the problem solving method of the problem to be solved according to the attribute information of the problem and the condition corresponding to each problem solving method.
Since each higher-level problem solving method has a large number of lower-level branches, and each lower-level problem solving method can be used only when the problem meets the condition of the higher-level problem solving method, in order to reduce the number of times of comparing the problem attribute with the condition corresponding to each problem solving method and improve the efficiency, in one possible implementation, the step S102 can be implemented by the following steps:
1) and searching the problem solving label matched with the problem attribute information according to the problem attribute information corresponding to the object to be solved and the sequence of the problem solving labels from the upper level to the lower level until the lowest problem solving label matched with the problem attribute information is determined.
2) And determining the problem solving method corresponding to the lowest problem solving label as the problem solving method corresponding to the problem to be solved.
In the step 1) and the step 2), each level of problem solving label can correspond to a one-level problem solving method, and specifically, the uppermost level of problem solving label can correspond to a vertical calculation method, a off-line calculation method and other problem solving methods; under the vertical calculation problem solving label, the next level problem solving label can correspond to the addition vertical calculation and the like.
The problem solving label can carry a problem solving method corresponding to the problem solving label and the problem attribute information corresponding to the problem solving method.
Therefore, whether the item to be solved is consistent with the item attribute information corresponding to the higher-level solving method or not is determined through the hierarchy label, and if so, whether the item attribute information corresponding to the lower-level solving method is consistent or not is determined, the lowest-level solving label can be determined without traversing all solving methods, and the solving method corresponding to the lowest-level solving label is used as the solving method corresponding to the item to be solved.
Specifically, in some possible embodiments, step 1) may be implemented by:
determining an Nth-level problem solving label matched with the problem to be solved according to at least one type of problem attribute information corresponding to different Nth-level problem solving labels and the problem attribute information of the problem to be solved; the initial value of N is 1;
determining an N +1 th level problem solving label matched with the to-be-solved problem according to at least one type of problem attribute information corresponding to the N +1 th level problem solving labels under the N th level problem solving label and the problem attribute information of the to-be-solved problem; n +1, and repeating the steps until the lowest-level problem label matched with the problem to be solved is determined.
In this step, if the problem attribute information of the to-be-solved problem has all the problem attribute information corresponding to the nth set of problem tags, it may be determined that the to-be-solved problem matches the problem tags, after the matching is determined, it may be determined whether the problem attribute information corresponding to the secondary problem tags under the problem tags matches the problem attribute information of the to-be-solved problem, and it is guided to determine that the matched problem tags are the positions of the lowest-level problem tags, so that the problem solving method corresponding to the matched lowest-level problem tags may be used for solving the to-be-solved problem.
Furthermore, most questions do not only have a unique problem solving method, and when the lowest-level problem solving label matched with the question to be solved is determined, a plurality of lowest-level problem solving labels can be determined, or only one lowest-level problem solving label can be determined.
S103, generating a problem solving step described by a formal language according to the problem to be solved and the problem solving method.
In this step, a problem solving step described by a formal language may be generated according to the calculation logic corresponding to the problem solving method obtained in step S102, in combination with the problem attribute information of the problem to be solved.
The formal language is relative to a natural language, namely a language spoken by human, the natural language generates abundant words and infinite combinations for describing the surrounding world and knowledge in the development process of the human society, and the formal language is very difficult for a computer to understand while facilitating the human to express ideas. Formal languages are languages designed for specific applications, with simple grammatical rules to facilitate computer understanding and computation.
In some embodiments, step S103 may comprise:
generating a problem solving step described by a natural language according to the problem to be solved and the problem solving method;
and converting the problem solving step described by the natural language into the problem solving step described by the formal language according to a preset conversion relation between the natural language for describing various mathematical calculations and the formal language.
In this step, a problem solving step described in natural language may be generated according to the specific content of the problem to be solved and the calculation logic corresponding to the problem solving method obtained in step S102.
Illustratively, when the problem solving method is an iterative calculation, the following calculation logic can be used to generate the problem solving steps described in the natural language:
step 1: judging whether the formats of the numbers are consistent (at least two types exist in decimal/fraction/percentage);
if not, adjust all numbers to numbers with consistent format (typically convert percentages and decimal numbers to fractions);
explanation and display: converting all (percentage/decimal) into fractions, and then sequentially calculating according to the operation sequence;
otherwise:
explanation and display: calculating in sequence according to the operation sequence;
step 2: calculating the number in brackets;
detecting whether small brackets, middle brackets and big brackets exist;
if the brackets exist, calculating all parts in the small brackets;
explanation and display: ___ O (representing any operator) ___ (where there are a number of operations in small brackets, they should be listed one by one) within small (medium/large) brackets;
if the parenthesis is sibling:
explanation and display: ______;
example (c): 12+ (4+1) + (9-1);
calculating sequentially according to the operation sequence:
calculating 4+1 and 9-1 in brackets;
original formula is 12+5+ 8;
otherwise, there are different levels of operation in parentheses:
explanation and display: firstly, ____ O ____ is calculated as _____ (if there are multiple sibling operations, they should be listed and calculated at one time);
______;
then ____ O ____ is ______;
______;
skipping to the step 2;
otherwise, jumping to the step 3;
and step 3: calculating a second-level operation;
if multiplication and division exist:
calculating all multiplication and division parts;
explanation and display: calculation ____ O ____ (where there are multiple operations in parentheses, one for each);
if there are multiple multiplications and divisions:
explanation and display: calculating from left to right in sequence;
calculating ____ O ____ ═ _____;
_______;
calculating ____ O ____ ═ ____;
_______;
otherwise:
explanation and display: ________;
otherwise, jumping to step 4;
step 4, calculating primary operation;
if the addition and subtraction are carried out in multiple steps:
explanation and display: calculating from left to right in sequence;
if the original formula only has addition and subtraction:
explanation and display: calculating ____ O ____ ═ ____;
_______;
calculating ____ O ____ ═ ____;
_______;
otherwise:
explanation and display: _____;
wherein, the content behind the explanation and display is the problem solving step described by the natural language.
Further, after the step of solving the problems described by the natural language is generated, the step of solving the problems described by the natural language can be converted into the step of solving the problems described by the formal language according to the conversion relationship between the natural language and the formal language.
The conversion relationship between the natural language and the formal language may be predetermined.
Illustratively, if the subject to be solved is "calculate 99-11", the natural language form of the first step of the solving step is "split 99 to 90+ 9", and the equivalent expression of the formal language may be "(and (separate99(+ 909)) (separate99(+ 909))", where "and" means "are added to" b "(+ x y means" x "and" y "are added to" b ".
In addition, verbs such as compute, add, multiply, and the like may be defined; decimal, fractional, integer, and the like, and logical relationships such as and, or, then, and the like.
In another example, "90 and 10 are subtracted, resulting in 80" can be converted to "(result (minus 9010) 80)".
Therefore, the problem solving step in the natural language form is converted into the form language which can be recognized by a machine, and the problem solving step can be demonstrated through a computer.
And S104, generating a problem solving dynamic picture corresponding to the to-be-solved problem based on the problem solving step described by adopting the formal language.
In this step, after the problem solving step described by the formal language is obtained, the problem solving step may be analyzed by using a parsing technique, and a problem solving dynamic picture corresponding to the problem to be solved is generated according to the data obtained by the analysis.
In some possible embodiments, step S104 may include:
and generating a problem solving dynamic picture for sequentially displaying each problem solving step according to the sequence of the problem solving steps based on the problem solving steps described by the formal language and the set dynamic display effect.
Here, the dynamic display effect may be that after one problem solving step is displayed, the next problem solving step is displayed after a preset time (for example, 3 seconds) is paused, and display effects such as "fly-in, bounce, underlining of a key step, and thickening of a key step" may be introduced in the process.
It will be understood by those skilled in the art that in the method of the present invention, the order of writing the steps does not imply a strict order of execution and any limitations on the implementation, and the specific order of execution of the steps should be determined by their function and possible inherent logic.
Based on the same inventive concept, the embodiment of the present disclosure further provides a problem solving demonstration apparatus corresponding to the problem solving demonstration method, and since the principle of the apparatus in the embodiment of the present disclosure for solving the problem is similar to the problem solving demonstration method in the embodiment of the present disclosure, the implementation of the apparatus can refer to the implementation of the method, and repeated details are not described again.
