With continued reference to FIG. 2, a flow 200 of one embodiment of a method for determining information in accordance with the present disclosure is shown, including the steps of:

step 201, in response to receiving a calculation request for a target formula group, storing the target formula group in a target storage space, pointing a pointer to a first formula in the target storage space, and performing an iterative operation.

In the present embodiment, when an execution subject (e.g., the server 105 shown in fig. 1) of the method for determining information receives a calculation request for a target formula set, the target formula set is stored in a target storage space, and a pointer for extracting data/information is pointed to a first formula in the target storage space.

The iterative operation includes step 2021, step 2022, and step 2023.

Step 2021, using the formula pointed by the pointer as the current formula, and identifying each functional expression in the current formula.

In this embodiment, the formula pointed to by the pointer is taken as the current formula, and each of the expressions in the current formula is identified. The formula group refers to a complete calculation process edited by a user, and each formula in the formula group is each assignment statement in the calculation process; the expression refers to the statement/content/information on the right side of the equal sign in each assignment statement; the functional expression comprises a function identification and a parameter, and the execution subject can call the function corresponding to the function identification and calculate the result of the functional expression based on the parameter. For example, in the formula group shown in fig. 3, each row is an assignment statement, i.e., each row is a formula, and the right side of the equal sign in each formula is an expression, i.e.: "(f) (a), h (b), g (c),. · t", "trimean (y, 2/8)" and "k (y, z) + l (3)" are expressions, each of which includes a functional formula, that is: "f (a)", "" h (b) "," "g (c)", "" trimean (y, 2/8) "," k (y, z) "," l (3) "are all functional expressions, and in the functional expressions, the information outside the parentheses represents the function name or the function identifier, and the information inside the parentheses represents the input parameters of the functional expressions. It is understood that the parameter in the functional expression may also be an expression, and one expression may include a plurality of functional expressions. The arithmetic logic of each functional expression may be stored in advance in the execution main body, or may be stored in advance in another device communicatively connected to the execution main body.

Step 2023, determining the result of the expression based on each function value, pointing the pointer to the next formula of the current formula, and using the result of the expression as the input parameter of the function in the iteration operation of the next round.

And step 203, in response to determining that the preset field exists in the current formula, stopping iteration operation, and determining the result of the expression determined in the last iteration operation as target information.

In this embodiment, when it is determined that a preset field exists in the formula pointed by the pointer in the current iteration round, the iteration operation is stopped, and the result of the expression determined in the last iteration round is determined as the target information. Here, the preset field may exist on the left side of the equation equal sign, that is, the label of the current equation calculation result, such as "result" in fig. 3, and the preset label may also exist on the right side of the equation equal sign, such as marking the preset symbol at the end of the right expression. "or a preset flag" End ", etc.

In response to receiving a calculation request for a target formula set, the method for determining information stores the target formula set in a target storage space, points a pointer to a first formula in the target storage space, and performs the following iterative operations: taking a formula pointed by the pointer as a current formula, and identifying each function in expressions in the current formula; for each functional expression in the expression, determining a function value of the functional expression by adopting the operation logic of the function indicated by the functional expression and the input parameter in the functional expression, and replacing the functional expression in the expression by adopting the function value; determining the result of the expression based on each function value, pointing the pointer to the next formula of the current formula, and taking the result of the expression as the input parameter of the function formula in the iteration operation of the next round; in response to the fact that the preset field exists in the current formula, the iteration operation is stopped, the result of the expression determined in the last iteration operation is determined as target information, the formula group edited by the user is identified as a model of formula, expression and functional formula, the expression execution is triggered by formula execution in the formula calculation process, the functional formula execution is triggered by expression execution, the expression execution and the functional formula execution are continuously triggered by functional formula execution, execution logic of recursive iteration is formed among the three, and the efficiency of determining the target information according to the formula group edited by the user can be improved.

With continued reference to FIG. 4, a flow 400 of another embodiment of a method for determining information in accordance with the present disclosure is shown, comprising the steps of:

in step 401, in response to receiving a calculation request for a target formula group, the target formula group is stored in a target storage space, a pointer is pointed to a first formula in the target storage space, and the following iteration operations are performed.

Step 4021, using the formula pointed by the pointer as the current formula, and identifying each function in the expressions in the current formula.

Step 4022, for each of the expressions, in response to determining that the sub-expressions are included in the function, identifying and obtaining the function of the sub-expressions.

In this embodiment, for each of the expressions, if other sub-expressions are included in the expression (the expressions nested in the expressions may be referred to as sub-expressions), the function in the sub-expressions is identified and obtained.

Step 4023, determining a function value of the function formula by adopting the operation logic of the function indicated by the function formula and the input parameter in the function formula for each function formula in the expression, and replacing the function formula in the expression by adopting the function value.

And step 403, in response to determining that the preset field exists in the current formula, stopping iteration operation, and determining the result of the expression determined in the last iteration operation as the target information.

In this embodiment, the descriptions of step 401, step 4021, step 4023, step 4024, and step 403 are the same as the descriptions of step 201, step 2021, step 2022, step 2023, and step 203, and are not repeated here.

In some application scenarios, as shown in fig. 5, the execution subject of the method for determining information may include a formula parsing module, an expression parsing module, and a functional parsing module, and the method for determining information may include:

after the execution main body receives a calculation request aiming at a target formula group, the formulas in the target formula group are stored in a target storage space line by line, the formula analysis module scans the formula group line by line, the equal-number right side of each line of the formulas is determined to be an expression, and the expression is sent to the expression analysis module for analysis and execution.

And the expression analysis module identifies the functional formulas in the expressions after receiving the expressions sent by the formula analysis module, and sends the analyzed functional formulas to the functional formula analysis module one by one for analysis and calculation.

And after receiving the function formula sent by the expression analysis module, the function formula analysis module identifies parameters in the function formula and detects the parameters parameter by parameter so as to detect the type of each parameter. The type of the parameter in the functional expression may be an expression, a functional expression, a numerical value or a text. If the parameter in the functional formula is an expression, the expression is sent to an expression analysis module for analysis and calculation; if the parameter is a functional expression, analyzing and calculating in the functional expression analysis module; if the parameter is a numerical value or a text, the numerical value or the text is used as an input parameter and is input into the arithmetic logic of the loaded/called function to participate in the calculation of the realization function.

After the function formula analysis module obtains parameters contained in all function formulas, calculation of the function formulas is achieved based on operation logic of the called functions, calculation results/function values are returned to the expression analysis module, the expression analysis module replaces the function formulas in the expressions by the function values corresponding to the function formulas, calculation of expression results is completed based on an expression dynamic operation mechanism, the results are returned to the formula analysis module, and the formula analysis module assigns values of the expressions to variables on the left side of the equal sign.

If the variable name of the formula in a certain row is a preset field, the formula is represented as the formula in the last row in the formula group, the result of the formula is target information required by the user, and the target information can be fed back to the user.

Compared with the embodiment described in fig. 2, the method for determining information provided by this embodiment adds the step of identifying and acquiring a function expression in sub-expressions when the sub-expression is included in the function expression, and can improve the efficiency of identifying an expression or a function expression in the case of nesting the expression in the function expression.

In some alternative implementations of the embodiments described above in connection with fig. 2 and 4, identifying each of the expressions in the current formula includes: identifying characters in an expression in a current formula; and determining the functional expression contained in the expression according to the character string formed by the characters in the expression.

In the embodiment, for an expression in a current formula, characters in the expression are identified, and a functional formula included in the expression is determined according to a character string formed by the characters in the expression.

Specifically, the recognized characters may be arranged in the order of the characters in the expression and constitute a character string, which is determined as a functional expression included in the expression.

Specifically, as shown in fig. 6, an expression parsing step is first performed, which may identify characters in an expression, determine a record item state according to a character identification result, and determine an operation to be performed according to the record item state. The entry is a temporary character string formed by splicing the currently scanned characters.

Firstly, characters in the expression are identified according to the sequence from left to right, and the characters are determined.

Secondly, in the process of sequentially identifying the characters from left to right, determining the content in the current record item according to the currently identified characters, and executing corresponding operation according to the record item state/the content of the record item.

Wherein the characters may include: operators (e.g., +, -,'s', etc.), punctuation marks (e.g., commas, dot symbols), brackets (left brackets and right brackets), and the like. The entry states include: whether the current entry is a function, whether the current entry is empty, and whether the bracketed offset for the current entry is equal to 0. The bracket skewness is used for describing the symmetrical state of the left bracket and the right bracket, if the skewness is 1 (or other preset marks), the left bracket is more than the right bracket in the record item by one, if the skewness is-1 (or other preset marks), the right bracket is more than the left bracket in the record item by one, and if the skewness is 0 (or other preset marks), the left bracket and the right bracket in the record item are equal in number. The performing operation corresponding to the entry state includes: splicing the current scanning character to a record item, splicing the current scanning character to a parameter item, marking the record item as a function, establishing a function object and caching, emptying the record item and emptying the parameter item, wherein the record item has the number of brackets of +1 and the number of brackets of-1. Wherein, the parameter item is a character string composed of parameter parts of the functional expression, such as "average ((a, medin (b))" the parameter item of the functional expression is "a, medin (b)".

After the expression is analyzed and all the functional expressions are obtained, executing the steps, and executing calculation operation on the expression: first, the calculation result of the expression already calculated in the formula is obtained. It should be noted that the formula is calculated according to the sequence of the expressions, the result of the expression calculated in the previous step is assigned to the relevant variables, these variables will be used as parameters to be transmitted to the following expression object for use, and the following expression does not necessarily use all these variables, depending on whether these variables are referred to in the following expression or not.

Secondly, analyzing and calculating the cached functional expressions one by one in the expression analysis process, namely calling a functional expression analysis module to analyze and calculate the functions. And after the function values of all the function formulas in the expression are obtained, replacing the corresponding function formulas in the expression by the function values.

And finally, calculating the result of the expression by adopting an expression dynamic operation mechanism, and returning the result to the formula analysis module, so that the calculation of the expression is finished.

In the embodiment, character recognition, entry state recognition and execution of the operation processing expression corresponding to the entry state are adopted in the analysis process of the expression, so that the efficiency of analyzing the expression can be improved, and the operation and maintenance cost can be reduced. And the result is calculated based on the expression dynamic operation mechanism, so that the generation of a temporary object instance can be avoided, and the waste of system storage resources is reduced.

In some alternative implementations of the embodiments described above in conjunction with fig. 2 and 4, determining the function value of the functional formula using the operation logic of the function indicated by the functional formula and the input parameter in the functional formula includes: identifying characters in the functional expression, and determining parameters in the functional expression according to the characters; and determining the function value of the functional formula by adopting the operation logic of the function indicated by the functional formula and the parameters in the functional formula.

In this embodiment, a character in the functional formula may be recognized, a parameter in the functional formula may be determined from the character, and a function value of the functional formula may be determined using the operation logic of the function indicated by the functional formula and the parameter in the functional formula.

Specifically, as shown in fig. 7, performing the functional formula parsing step first may identify characters in the expression, determine the entry state according to the character recognition result, and determine the execution operation according to the entry state.

Firstly, the characters in the functional expression are identified according to the sequence from left to right, and the characters are determined.

Secondly, in the process of sequentially identifying the characters from left to right, determining the content in the current record item according to the currently identified characters, and executing corresponding operation according to the record item state/the content of the record item.

This embodiment increases the state in which the entry is a parameter, compared to the previous embodiment. It should be noted that the same entry can be labeled as a function and a parameter at the same time, and when labeled as a parameter, it indicates that the currently scanned character belongs to the parameter part of the functional formula, otherwise, the currently scanned character belongs to the name part of the functional formula

In this embodiment, the performing operation corresponding to the entry state further includes: splicing the characters to parameter items, wherein the parameter items are independently used as a cached character string for storing the parameters of the function; constructing an expression object and caching; the record item is marked as a text parameter and cached; and canceling the mark of the record item, and canceling all marks on the record item, including an expression mark, a function mark or a parameter mark.

After the functional formula analysis is completed, executing the following steps: circulating all cached parameter items, if the parameter items are expression objects or function objects, analyzing and calculating values of the expressions or the function, and transmitting results serving as parameters into the function; if the parameter item is the result of the calculated expression in the formula, acquiring a numerical value corresponding to the result, and transmitting the numerical value into the function formula; if the parameter item is a text type parameter, the parameter item is directly transmitted into the functional expression. Thereafter, the functional expression is calculated based on the operation logic indicated by the functional expression and the result is returned to the expression.

In the embodiment, in the analysis process of the functional expression, character recognition, record item state recognition and execution of the operation processing expression corresponding to the record item state are adopted, so that the efficiency of analyzing the expression can be improved, and the operation and maintenance cost can be reduced. And the result is calculated based on the expression dynamic operation mechanism, so that the generation of a temporary object instance can be avoided, and the waste of system storage resources is reduced.

In some alternative implementations of the embodiments described above in connection with fig. 2 and 4, the input parameters in the functional formula include data associated with the target item, and the target information includes attribute information of the target item.
