Description

Method and device for realizing Chinese business rule engine, server side and storage medium

Technical Field

The present invention relates to the technical field of chinese business rule engines, and in particular, to a method and apparatus for implementing a chinese business rule engine, a server side, and a storage medium.

Background

The business rule engine is developed by the reasoning engine, is a component embedded in the business system, writes business rules through predefined semantics, receives input business data, and makes corresponding decisions according to the business rules. The business rule engine is used for releasing complex and changeable business rules from the system codes, and storing the business rules into files or specific storage media (such as a database) in the form of rule scripts, so that the change of the business rules can be immediately effective in an online environment without modifying the codes or restarting a server.

Most of the rule generation methods adopted by the existing rule engines describe rules based on the frames and grammar of programming languages, generally require rule editors to have higher software technical knowledge, and also require rule editors to be familiar with related grammar and algorithm principles and to know related program variable meanings so as to understand and configure the rules, and common business personnel generally do not have the technical capabilities, and the obtained rule contents are still not friendly and intuitive enough for the common business personnel.

Such rule generating methods need to directly call data objects in system codes, for example, open source rule engine Drools developed based on Java language, and usually need to use programs to create entity class objects when rule writing is performed, the attributes of the entity class objects are difficult to dynamically change, and the creation and maintenance of the entity class objects need to be completed by personnel with software development capability; the grammar of the Drools built-in language is mainly compatible with Java grammar, and has high learning cost although the language is easy to compile and execute.

Moreover, because the current rule engine is basically based on English environment, the words and grammar in the Chinese are not friendly, the formed rules are very different from natural language, and common business personnel are difficult to independently complete the rule programming work. In addition, current rule engines lack the necessary classification, dimension, and conflict checking.

In a first aspect, referring to fig. 1, fig. 1 is a flowchart of an implementation method for a chinese business rule engine according to an embodiment of the present invention, where the rule engine implementation method is applied to a server, and includes:

s300, forming a rule set by utilizing a plurality of Chinese rules, and linking the rule set into an event so as to call a Chinese rule engine through the event; and when the event is triggered, calling the rule set to calculate so as to directly convert the rule set into computer executable codes and returning a result.

Specifically, in step S100, the present invention constructs a chinese business rule pattern, a rule guiding word library and a chinese object model library, which conform to the chinese grammar characteristics, so as to facilitate the business personnel to grasp.

Regarding chinese business rules, the rule content of which includes a condition part and an action part, may be written in a predefined semantic format to describe the activities and/or relationships of the first object model and/or the second object model. Specifically, the predefined grammar format takes { if } < condition > { then } < action > as the principal form;

to reduce the conditional expression statement, a { if }, a { when } complex condition may also be set:

{ if } < Condition 1 ]

{ when } < condition 2> { then } < action 1>

{ when } < condition 3> { then } < action 2>

That is, since the format requirements of the chinese rules engine are relatively fixed, the format of the chinese business rules can only be either format 1 or format 2:

format 1:

{ if } < condition > { then } < action >

Format 2:

{ if } < Condition 1 ]

{ when } < condition 2> { then } < action 1>

{ when } < condition 3> { then } < action 2>

It will be appreciated by those skilled in the art that the conditions in format 1 AND format 2 described above for the chinese business rules may be a combination of a plurality of specific condition clauses, for example, the form of < condition > in format 1 may be < expression 1> { AND } < expression 2> { AND } < expression 3>, where { AND } ({ AND }) is used to represent an intersection operation, AND { AND } may also be replaced with { OR } ({ OR }) is used to represent a union calculation, thereby enabling a determination that a plurality of conditions are satisfied simultaneously.

The condition clause is also called a logic condition, specifically, the logic condition refers to an expression capable of returning a boolean variable, and may be a method or a logic operation. Execution of the condition returns that the result should be a boolean variable (one of True, false). The action may be a combination of a plurality of sub-actions, and the actions may be separated according to a predetermined convention, for example, by a semicolon.

The rule guiding word library comprises a plurality of rule guiding words used for the condition part and/or the action part;

preferably, the first rule guide is one of "if", "when", "if" and the second rule guide is one of "then", "then".

For example: for a material purchase order, if the purchase period of the specified components is 3 months, the rule expression statement using the rule guide word may be:

if material classification= component

Then purchase cycle = 3 months

Wherein the meaning represented by "= =" is a condition judgment operator, checking whether the values of two operands are equal, if equal, the condition is true; the meaning of "=" is an assignment.

The rule guiding word library can also comprise Chinese circulation guiding words, which are similar to Chinese rules, if an object set is set and circulation is expected to be carried out according to the identification of the object, the keyword 'certain' must be adopted when the object appears for the first time, and the keyword 'the' must be adopted when the object appears every time later, so long as the same object is referred to.

That is, the third rule guide word is "certain", the fourth rule guide word is "this", and both the third rule guide word and the fourth rule guide word are chinese cyclic guide words.

For example: for reimbursement list, the travel of difference has many days, except for return, the stipulated department stem part is subsidized for 200 yuan every day, and then the regular expression statement containing Chinese circulation guide words can be:

if a sales person is reporting that level= is in place and some [ day of travel ]. Date ]! End day of travel

Then the [ day of travel ] the additional amount = 200 yuan.

The meaning represented by "= =" is a condition judgment operator, which checks whether the values of two operands are equal, and if equal, the condition is true. "|! The meaning of the = "expression is to check whether the values of the two operands are equal, and if the values are not equal, the condition is true.

The Chinese object model library comprises a plurality of object models for the condition part and/or the action part, and each object model comprises a plurality of attributes and methods.

For example, for a material purchase order, the object model includes attributes such as material category, advance period, person filled in, date filled in, etc. The reimbursement list can be divided into a main table, wherein the object model of the reimbursement list main table can comprise the attributes of reimbursement person, level, departure date of travel, end date of travel and the like, the reimbursement list is for example a travel table, the travel date is used as a unique identifier, and the object model of the travel table can comprise the attributes of travel date (mark attribute), reimbursement amount, auxiliary amount and the like.

Each object model may also include a method, which may be an action performed on the object, such as querying whether the object exists, taking the object model of a reimbursement list master table as an example, and which may be querying whether a reimbursement list master table numbered xxxxx exists.

The object model is used for the condition part or action part of Chinese business rules, such as the condition part "if a person is reported, level= is positive and some [ day of travel ]. Date ]! The object model of the reimbursement list is used, and the attributes of reimbursement person, business day and the like are adopted to write the conditions.

Specifically, in step S200, after the user writes the chinese business rule according to the chinese business rule mode, the server invokes the chinese rule engine to verify the rule after receiving the chinese business rule, so as to ensure validity and executable of the chinese business rule.

In one example, the verification is divided into the following steps:

(1) The Chinese business rules are first partitioned into conditional statements and action statements using rule guide words (if, when, etc.).

(2) Processing the conditional statement to form a conditional set

In this processing step, two OR more logical conditions connected by AND OR OR are formed into a condition set that includes all the logical conditions in the rule.

In this process, it is also determined whether or not each logical condition has a logical operator (>, < etc. logical operator). If a logic operator exists in a certain logic condition, the logic operator is extracted, and two end parts of the logic operator are respectively extracted and identified, and the content of each part can be any one of the following:

the first is model and attributes (e.g., person. Age);

the second is a model approach (e.g., people & query ages);

the third is the literal quantity, which may be of the character type or of the numerical type (in this case, the dimension is necessary);

the fourth is a variable, which is divided into a user-defined variable and a built-in system variable,

where the system variable is a variable that the system knows the content, such as: current time, current login user, etc. The user may also customize the variables in Chinese, but the user-defined variables can only be validated within the rules.

If there is no logical operator in a logical condition, then the content of the logical condition must contain a certain method of the model, and the action must return a boolean variable (one of True, false).

For example, a logical condition is "reimbursement sheet & query exists (number: 111027)", meaning whether reimbursement sheet with query number 111027 exists, the logical condition does not exist as a logical operator, but includes a method, and its corresponding action must also return a boolean variable (True indicates that the reimbursement sheet exists, false indicates that the reimbursement sheet does not exist).

(3) Processing the action sentences to form an action set

In this processing step, all actions are formed into an action set, specifically, each "in chinese business rules; "the previous parts are actions.

The actions are divided into an assignment type and a method type, and in the processing process, whether the actions are of the assignment type or the method type is also judged:

if the action is of an assigned type (i.e. the action includes "=", such as reimbursement order, business trip subsidy=200 elements), the extraction is also performed on the two end portions of "=", and the content of each portion may be any of the following:

the first is model and attributes (person. Age);

the second is the literal quantity, which may be of the character type, and may be of the numerical type (which must have dimensions);

the third is a variable, which is classified into a user-defined variable and a built-in system variable.

"=" is an assignment symbol, and appears in an action instead of a conditional statement (when judging whether or not the conditions are equal in the conditional statement, it is necessary to judge the symbol "= =") with a relationship.

If the action is of the method type (i.e. the action contains "&", such as reimbursement sheet & set business trip subsidy (200 yuan)), then the content of the action includes the model and method.

(4) A check set is generated for each model, including the names of the model, attributes, and methods.

(5) And judging the validity of the rule in a manner of semantically checking the rule, including checking whether the rule guide word is used correctly, whether an object model and an attribute exist or not, and the like.

Through the steps, the compliance and consistency of the rule content can be ensured, the Chinese rule engine can easily interpret the rule content, and the accuracy of the rule content and the efficiency of rule execution can be improved. Moreover, the rule content is checked or semantically checked when the rule content needs to be stored, so that the problem can be found out in time and the error can be corrected.

(6) And performing language conversion on the Chinese business rule after successful verification, automatically converting the Chinese names of the model, the attribute, the method, the variable and the dimension into corresponding English names in a system platform, splicing the converted English names into corresponding sentences according to the conversion of the logic operator and the content, and storing the English names in a full English form.

For example: extracting contents of two end parts according to the condition part of 'reimbursement bill and amount >100 yuan' in the Chinese business rule, and converting the 'reimbursement bill and amount' after verification is legal into bxd. After the 100-element verification is legal, converting the result into 100yuan; finally, splicing: bxd.nine >100yuan.

Specifically, in step S300, a plurality of chinese business rules may constitute a rule set, and the rule set may be linked to a certain event. The event is a call entry of the Chinese business rule engine, the event can be that a certain link is clicked, a certain button is pressed, a certain page is refreshed, and the like, and the event represents a trigger action. For example, a button name called "subsidy calculation" may be set on the page of the reimbursement sheet, and when the button is pressed by the user, an event of "subsidy calculation button press" is triggered. When the rules engine receives this event, it invokes the "subsidy calculation button press" corresponding rule set, which in one example has a plurality of rules therein, including, for example:

rule 1: if a sales person is reporting that level= is in place and some [ day of travel ]. Date ]! The [ day of travel ] is the end of travel =200 yuan of the additional amount =

Rule 2: if a sales person reports a level= secondary and a certain [ day of travel ]. Date ]! The [ business day ] is the last day of business trip =the additional amount =150 yuan =

Rule 3: if a sales person, job title= =researcher and some [ travel day ]. Date-! The [ day of travel ] = end of travel ] the additional amount = 300 yuan

After the event of 'subsidy calculation button pressing' is triggered, the rule set is called to calculate, the rule set is directly converted into a computer executable code, and a corresponding result is returned.

Further, in the step S100, a model action library is further constructed in advance, where the model action library includes a plurality of first functions, and each first function is used to associate with one object model, so that the first function operates on the associated object model.

In particular, according to chinese language habits, the first function must be a verb in the language and must adhere to the model. The first function may be a simple verb (action) or a verb (action) with a specific description, and the specific description may be a parameter of the first function.

For example: for the reimbursement sheet, the object model may be subject to the action of nullification, and the first function may be a mere nullification action, e.g., the first function associated with the reimbursement sheet, the object model is "reimbursement sheet & nullification ()".

However, the reimbursement bill will have a reason for reimbursement, such as expiration date, false invoice, reimbursement person withdrawal, etc., so the reason for the reimbursement action can be specifically described, and the specific reason description can be taken as a parameter, and the first function associated with the object model of the reimbursement bill can be "reimbursement bill & reimbursement (expiration date)".

Further, in the step S100, a dictionary model library is pre-built, and the dictionary model library includes a plurality of dictionaries, and the dictionaries include information item keys and information item values; when the data type of a certain attribute of the object model is set to be a text type, the data source of the attribute is associated with a certain dictionary in the dictionary model library.

For example, the material classification may be a dictionary and may include components, raw materials, metals, non-metals, and others, one of which must be selected.

The business city may also be a dictionary, which may be composed of province and city two-level sites. For reimbursement sheets, the object model may include an attribute of the business trip destination, the data type of which is text (since city names are typically entered in text form), and the data source of which may be associated with the dictionary of business trip cities.

Further, in the step S100, a dimension model library is further constructed in advance, the dimension model library includes a plurality of dimensions, and the dimensions include a plurality of units and conversion relationships therebetween; when the data type of a certain attribute of the object model is set as a numerical value type, the attribute is associated with a certain dimension in the dimension model library.

For example, the dimension model library may include a monetary dimension that includes a plurality of units, such as RMB, euro, dollars, and the like, and a conversion relationship between these units.

For the object model of the reimbursement bill, there is usually an attribute of reimbursement fee, obviously the data type of the attribute is usually a numerical value, the attribute can be associated with the currency dimension in the dimension model library, the default unit of reimbursement fee is (element, RMB) or (element, euro) when reimbursement is performed, and the real-time exchange can be realized according to the real-time exchange rate of the RMB and the Euro.

Further, in the step S200, determining validity of the condition set and the action set includes performing semantic checking on the rule, and specifically includes: it is checked whether the rule-guided words are used correctly, whether object models, attributes and/or associated function models exist, whether the data types of the attributes and function models agree, whether the literal quantity assignment and the dictionary model agree, and whether the literal quantity assignment includes a dimension model.

Further, in the step S300, after linking the rule set to an event, it further includes performing a conflict check on each rule linked to the event, if there is a conflict content, prompting the conflict content and prompting the user to revise the rule, and if there is no conflict content, maintaining the rule in the database in english form.

Conflict checking: when a rule is referenced to an event, the system automatically checks the rule for conflicts with other rules in the event.

Specifically, rule contents of all rules are combined into a rule set, and conflict checking is performed on the rule set.

Further, the conflict check includes:

any two rules are selected as the first rule and the second rule,

repeating the steps until the conflict check of all rules is completed.

Examples of partial inclusion relationships are as follows:

the content of the first rule is:

"if reimbursement sheet, reimbursement person, job=in place

Then reimburse list, subsidy = 300 yuan'

The content of the second rule is:

' if reimbursement sheet. Reimbursement person job=in place

Then reimburse list, subsidize >200 yuan'

The first rule and the second rule belong to partial inclusion relation, no conflict exists, and modification is not needed.

Examples of conflicting relationships are as follows:

the content of the first rule is:

"if reimbursement sheet, reimbursement person, job=in place

Then reimburse list, subsidy = 300 yuan'

The content of the second rule is:

' if reimbursement sheet. Reimbursement person job=in place

Then reimburse list, complement >400 yuan'

The first rule and the second rule belong to a conflicting relationship and must be modified.

As a further improvement of the above embodiment, the conflict check further includes:

Selecting any rule as a third rule;

if the condition part of the third rule is limited by the preamble rule and the judging object of the condition part is empty, the third rule is an invalid rule;

and if the action part of the third rule has cyclic application, the third rule is a cyclic rule.

If the conflict check fails, the conflict content is prompted, and because the existence of the conflict causes an uncertain execution result, the conflict information is reported to the user after the conflict, and the user is prompted to revise the rule again. If the conflict check is successful, the Chinese business rule is saved in a database in Json format according to all English modes in consideration of the Chinese compatibility problem of the programming language.

The storage format of the Chinese business rule is exemplified as follows:

/>

further, in the step S300, the event includes, but is not limited to, the following scenarios: such as page refreshed, button pressed, form submitted, form flow completed, or timing of system control.

Further, in the step S300, the calculating includes: firstly checking rules to ensure the correctness and the validity of the rules, initializing input data after the rules pass, transmitting the input data to a model, compiling the processed rule content into a program language or directly transmitting the compiled code as the input data, injecting the processed input data into the compiled code as input parameters, and returning the result.

Since elements in the rule, such as models, attributes, methods (functions) and dimensions, may change after the rule is stored, the calling time of the rule is affected by the event and is uncertain, so that the correctness and validity of the rule are affected. So that a check is made before rule execution, if these factors change (e.g., are modified or deleted) the rule is mislaid, stopping rule execution. If the check is passed, the input data is initialized.

The input data (typically in terms) is initialized according to a list of models contained in the rules, and in particular, if the model names in the input data match, the part of the data is assigned to the corresponding model.

For example, in the rule of subsidized calculation, attributes such as the level and title of the sales person are used, and records in the bad travel schedule are also used, and these data are all transferred to the model.

And taking the initialized input data as input parameters, injecting the input parameters into the constructed function statement, triggering an execution command to execute the constructed statement, and returning a result. Because the Chinese rule engines have good independence, when the data volume is large, the data can be grouped, and a plurality of rule engines can be called to complete tasks in parallel.

When constructing the function statement, the processed rule content is directly translated into the corresponding computer language according to the rule format requirement of the corresponding computer language. If the language is a compiling type language, executing a dynamic compiling program; if interpreted language, the steps are not needed.

The pre-translation rules are invoked in a stored format into a rules engine, in the form shown below:

if_condition_expression = "xmfp. Xmleixing=" research and development class "".

·or_condition_expression_list:"xmfp.jine<200yuan"

·action_expression_list:"bxd.bxjine＝200yuan"

The above rules are translated into programming language according to a fixed format, for example "= =" is translated into an equivalent () function, model attributes are translated into model get ("attribute value"), assignments are translated into model put functions, taking the above rules as an example, the following Java language can be translated, class binary files are obtained after compiling, and the virtual machine directly calls hardware to calculate to obtain results:

if (xmfp. Get ("xmleixing")) equal ("research and development class") |

xmfp.get("jine")<200){

bxd.put("bxjine",200)；}

The method is easy to expand to other programming languages such as C, C++, GO and the like.

And dimension processing is also performed on the calculated result, so that the dimension in the calculation process is consistent, and if the dimension is inconsistent, the dimension conversion program is required to be called for processing the dimension.

Further, each rule is provided with a priority, the priority of the rule is ordered from low to high before checking the rule, and the last execution with high priority is performed; priority is a description of the importance of a rule, with higher values being higher. Since the rules are executed orderly, the rules with the assigned values at the back can wash out the rules with assigned values at the front, and the rules with low priority at the front can be washed out when the level is larger and then executed.

Further, in the step S300, the calculating further includes: after the initialization processing of the input data is completed, performing classification relation processing, wherein the classification relation processing comprises the following steps: if the parent class is referenced in the rule, classification loop checking can be performed on all child pairs until all child data checking is completed.

The invention supports a class system in the model, and classes are inherited step by step. The lower level classification inherits the properties and actions of the upper level classification, and the lower level classification can create special properties and actions of its own class, but the created properties and actions must not conflict with the upper level classification.

For example: the invoice is classified into train ticket, food ticket, taxi ticket, airplane ticket, accommodation ticket and other subclasses, and each subclass has its own special attribute and method. Taking train tickets as an example, the train tickets can inherit invoice attributes of ticket numbers, billing units and the like, and can also build own attributes of train numbers, starting stations, arrival stations, seats, students, passengers, identity card numbers and the like.

Actions are inherited along with the category system, and invoices have actions of reimbursement and revocation. The train ticket has the special action of checking the ticket besides the action of reimbursement and revocation.

The model in the Chinese rule engine supports classification, and when the parent class is referenced in the rule, classification cycle checking is needed for all the sub-class objects until all the sub-class data checking is completed.

For example, for rules:

if $current date-certain invoice · date of invoicing > 90 days

Then the invoice & invalidate ();

the rule performs a cyclic check of all sub-class invoices (restaurant invoices, air tickets, train tickets, accommodation tickets, etc.) in the reimbursement ticket and performs an action.

Further, in the step S100, a dimension model library is pre-constructed, and when the data type of a certain attribute of the object model is set as a numerical value type, the attribute is associated with a certain dimension in the dimension model library;

For example, in the case of performing the dimension processing, all the dimensions of the variables may be unified into a standard unit (element) of the dimension for the monetary dimension, and the original dimension unit of the variables may be recorded.

For the time dimension, if the default unit of the dimension of the pre-built model is seconds, but the unit in the rule is days, then it is converted to seconds.

Thus, the number dimensions in the rule can be different from those in the database, and the correct result can be obtained.

A preferred embodiment of the invention is shown below by way of example.

Example 1：

The method for realizing the Chinese business rule engine specifically comprises the following steps:

1. pre-constructing Chinese business rule and object model library

By constructing a rule mode which accords with the Chinese grammar characteristics, the rule guide words and the Chinese object model are convenient for business personnel to master.

Regarding chinese business rules, the rule content of which includes a condition part and an action part, may be written in a predefined semantic format to describe the activities and/or relationships of the first object model and/or the second object model. Specifically, the predefined grammar format takes { if } < condition > { then } < action > as a body form, wherein the form of < condition > may be < expression 1> { and } < expression 2> { and } < expression 3>, wherein { and } is used to represent an intersection operation, { and } may also be replaced with { or } is used to represent a union calculation, thereby enabling judgment that a plurality of conditions are satisfied simultaneously.

{ if } < Condition 1 ]

{ when } < condition 2> { then } < action 1>

{ when } < condition 3> { then } < action 2>

Pre-constructing a Chinese rule condition guiding word library and a Chinese object model library, wherein: the rule guiding word library comprises a plurality of rule guiding words used for the condition part and/or the action part, and specifically comprises a first rule guiding word and a second rule guiding word;

the Chinese circulation leading word is constructed in advance, and is similar to the Chinese rule, if an object set is set and circulation is expected according to the identification of the object, the keyword 'certain' must be adopted when the object appears for the first time, and the keyword 'the' must be adopted when the object appears every time later, so long as the same object is referred to.

The object model library comprises a number of object models for the condition part and/or the action part, each object model comprising a number of properties and methods.

For example, for a material purchase order, there are attributes such as material category, lead time, person filled in, date filled in, and the like. The reimbursement list can be divided into a main list, wherein the main list of the reimbursement list has the attributes of reimbursement person, grade, business trip departure day, business trip ending day and the like, the reimbursement list has a business trip list, the business trip day is taken as a unique identifier, and the attributes in the business trip list have the attributes of business trip day (mark attribute), reimbursement amount, auxiliary amount and the like.

The variables in the system are divided into user-defined variables and built-in system variables. Where the system variable is a variable that the system knows the content, such as: current time, current login user, etc. The user may also customize the Chinese variables, but the customized Chinese variables can only be validated within the rules.

Pre-constructing a model action library, wherein the model action library comprises a plurality of first functions, each first function is associated with one or more object models, and the first functions are used for operating the associated object models; according to Chinese language habit, the function must be a verb in the language, must be attached to a model, and if the function is a simple verb, the function is also a function. If the action is also described, parameters may be used as a function of the action.

For example: the reimbursement bill can be voided, the voiding means that the reimbursement bill is sealed and stored, the attribute state is changed into 'voiding', and meanwhile, the reimbursement bill has voiding reasons: the status describing the nullification actions, such as expiration, false invoice, reimbursement, etc., may be validated together as parameters by the nullification actions. Examples are as follows:

reimbursement sheet & voiding ()

Reimbursement sheets & conducing (outdated)

A class system is supported in the model, and classes are inherited step by step. The lower level classification inherits the properties and actions of the upper level classification, which may establish own class-specific properties and actions, but the newly created properties and actions must not conflict with the upper level classification.

For example: the invoice is classified into train ticket, food ticket, taxi ticket, airplane ticket, accommodation ticket and other subclasses, and each subclass has its own special attribute and method. Taking a train ticket as an example, the train ticket inherits invoice attributes of a ticket number, an invoicing unit and the like, and also has information such as a train number, a starting station, an arrival station, a seat, whether students, passengers, an identity card and the like.

Actions are inherited along with the category system, and invoices have actions of reimbursement and revocation. In addition to this, the train ticket has the special action of checking the ticket.

Pre-constructing a dictionary model library, wherein the dictionary model library comprises a plurality of dictionaries, and the dictionaries comprise information item keys and information item values; the pre-built object model further comprises: when the data type of the attribute is set to be a text type, the data source of the attribute is associated with a certain dictionary in the dictionary model base.

For example, the material classification may be a dictionary and may include components, raw materials, metals, non-metals, and others, one of which must be selected. In the case of reimbursement sheets, the business trip city can also be a dictionary, and can be composed of two-level places of province and city.

Pre-constructing a dimension model library, wherein the dimension model library comprises a plurality of dimensions, and the dimensions comprise a plurality of units and conversion relations among the units; the pre-built object model further comprises: when the data type of the attribute is set to be a value type, the attribute is associated with a certain dimension in the dimension model library.

For example, the reimbursement bill usually has reimbursement fees, and the default unit is (Yuan, RMB) or (Yuan, euro) can be selected, so that real-time conversion can be realized according to the conversion prices of the RMB and the Euro.

2. Chinese business rule checksum storage

The user writes according to the Chinese rule grammar requirements, and when the user writes, namely when receiving a rule preservation command, the user invokes a Chinese rule engine which verifies the rule to ensure the validity and the executable of the Chinese business rule. The checksum storage is divided into the following steps:

1. Firstly, cutting out a conditional statement and an action statement by using keywords (if, when, then); since the format requirements of the chinese rules engine are relatively fixed, it is only format 1 or format 2.

Format 1:

{ if } < condition > { then } < action >

Format 2:

{ if } < Condition 1 ]

{ when } < condition 2> { then } < action 1>

{ when } < condition 3> { then } < action 2>

It should be understood that the condition in the above-described format 1 and format 2 may be a combination of a plurality of specific condition clauses, which are also referred to as logic conditions, and specifically, the logic conditions refer to expressions capable of returning boolean variables, which may be methods or logical operations. The conditional clauses may be connected by AND OR, AND the execution return result of the condition should be a boolean variable (one of True AND False). The action may be a combination of a plurality of sub-actions, and the actions may be separated according to a predetermined convention, for example, by a semicolon.

2. Conditional statement processing

(1) More than two logical conditions connected by AND OR OR form a condition set comprising all the logical conditions in the rule;

(2) Extracting logical operators of each logical condition (>, < etc. logical operation symbols), if a logical operator exists in a certain logical condition, extracting and identifying two end portions of the logical operator respectively, wherein the content of each portion can comprise any one of the following:

The first is a model and attributes (e.g., person. Age),

the second is a model method (e.g. person & query age ()),

the third is the literal quantity, which may be of the character type or of the numerical type (in which case it is necessary to have dimensions),

the fourth is a variable, which is divided into a user-defined variable and a built-in system variable;

For example, whether a reimbursement sheet & query exists (number 111027), meaning whether a reimbursement sheet with query number 111027 exists.

In addition, no assignment symbol can exist in the conditional statement, and a judgment symbol "= =" for judging equality needs.

3. Action sentence processing:

(1) Each "; "the previous parts are actions (i.e., actions), all of which form an action set;

(2) Actions are classified into an assignment type and a method type, and thus it is necessary to determine whether an action is an assignment type or a method type:

if the assignment type (i.e., the action includes "=", such as reimbursement list, business trip subsidy=200 yuan), the two end portions of "=" are extracted and identified, and the content of each portion may include any of the following: the first is model and attribute (person, age), the second is literal, can be character type, can be numerical (with dimension), the third is variable, and is divided into user-defined variable and built-in system variable; if method type (i.e. action contains "&", such as reimbursement sheet & set business trip subsidy (200 yuan)), then the content of the action includes model and method;

4. After decomposition is completed, generating a check set for each model, wherein the check set comprises the names of the model, the attribute and the method;

5. the rules are checked semantically. Whether the rule directs the use of words correctly, whether an object model, an attribute and/or an associated function model exists, whether the data types of the attribute and the function model are consistent, whether the literal quantity assignment and the dictionary model are consistent, whether the literal quantity assignment includes a dimension model, and the like.

6. Chinese names of models, attributes, methods, variables and dimensions are automatically converted into corresponding English names in a system platform, then the converted English names are spliced into corresponding sentences according to the conversion of logical operators and contents, and the corresponding sentences are stored in a full English form.

For example: the reimbursement bill and the sum of money is more than 100yuan. Extracting contents on two sides according to 'and reimbursement bill', and converting the contents into bxd.nine after the amount verification is legal; after the 100-element verification is legal, converting the result into 100yuan; finally, splicing: bxd.nine >100yuan.

7. Conflict checking: when a rule is referenced to an event, the system automatically checks the rule for conflicts with other rules in the event.

Specifically, rule contents of all rules are formed into a rule set, and conflict checking is carried out on the rule set, wherein the conflict checking comprises the following steps:

any two rules are selected as the first rule and the second rule,

if the intersection of the conditional part of the first rule and the conditional part of the second rule is not empty, and the action part of the first rule and the action part of the second rule are completely the same; or if the condition part of the first rule and the condition part of the second rule are identical, and the intersection of the action part of the first rule and the action part of the second rule is not empty, the first rule and the second rule are in a part inclusion relationship;

if the condition part of the first rule and the condition part of the second rule are partially the same, and the intersection of the action part of the first rule and the action part of the second rule is empty, the first rule and the second rule are in a conflict relationship;

repeating the steps until the conflict check of all rules is completed.

Examples of partial inclusion relationships are as follows:

the content of the first rule is:

"if reimbursement sheet, reimbursement person, job=in place

Then reimburse list, subsidy = 300 yuan'

The content of the second rule is:

' if reimbursement sheet. Reimbursement person job=in place

Then reimburse list, subsidize >200 yuan'

The first rule and the second rule belong to part of the inclusion relation without modification.

Examples of conflicting relationships are as follows:

the content of the first rule is:

"if reimbursement sheet, reimbursement person, job=in place

Then reimburse list, subsidy = 300 yuan'

The content of the second rule is:

' if reimbursement sheet. Reimbursement person job=in place

Then reimburse list, complement >400 yuan'

selecting any rule as a third rule;

8. If the conflict check fails, the conflict content is prompted, and because the existence of the conflict causes an uncertain execution result, the conflict information is reported to the user after the conflict, and the user is prompted to revise the rule again. If the conflict check is successful, the Chinese business rule is saved in a database in Json format according to all English modes in consideration of the Chinese compatibility problem of the programming language.

3. Execution of rules

Multiple Chinese business rules may form a rule set that may be linked to an event. The event is a call entry of the Chinese business rule engine, the event can be that a certain link is clicked, a certain button is pressed, a certain page is refreshed, and the like, and the event represents a trigger action. For example, a button name called "subsidy calculation" may be set on the page of the reimbursement sheet, and when the button is pressed by the user, an event of "subsidy calculation button press" is triggered. When the rule engine receives the event, the rule set corresponding to "the auxiliary calculation button is pressed" is called, and a plurality of rules exist in the rule set, for example:

rule 1 (priority 1): if a sales person is reporting that level= is in place and some [ day of travel ]. Date ]! The [ day of travel ] is the end of travel =200 yuan of the additional amount =

Rule 2 (priority 1): if a sales person reports a level= secondary and a certain [ day of travel ]. Date ]! The [ business day ] is the last day of business trip =the additional amount =150 yuan =

Rule 3 (priority 2): if a sales person, job title= =researcher and some [ travel day ]. Date-! The [ day of travel ] = end of travel ] the additional amount = 300 yuan

When a user or system triggers a corresponding event, the rule set in the event starts to execute, and the executing process is as follows:

1. ordering rule priority from low to high, and executing last with high priority; priority is a description of the importance of a rule, with higher values being higher. Since the rules are executed orderly, the rules with the assigned values at the back can wash out the rules with assigned values at the front, and the rules with low priority at the front can be washed out when the level is larger and then executed. In this example, rule 3 has a high priority level and so is executed later. At this time, if the reimburser is both a long and a researcher, then in rule 1, the subsidy is set to 200 yuan/day; later execution goes to rule 3, the subsidy is reset to 300 yuan/day.

2. Rule check (validity check, model validity check)

Since elements in the rule, such as models, attributes, methods (functions) and dimensions, may change after the rule is stored, the calling time of the rule is affected by the event and is uncertain, so that the correctness and validity of the rule are affected. So that a check is made before rule execution, if these factors change (e.g., are modified or deleted) the rule is mislaid, stopping rule execution. If the check passes, the next step is performed.

3. Input data processing: the input data (typically in terms) is initialized according to a list of models contained in the rules, and in particular, if the model names in the input data match, the part of the data is assigned to the model.

4. And (5) classifying relation processing. The model in the Chinese rule engine supports classification, and when the parent class is referenced in the rule, classification cycle checking is needed for all the sub-class objects until all the sub-class data checking is completed.

For example, for rules:

if $current date-certain invoice · date of invoicing > 90 days

Then the invoice & invalidate ();

the rule performs a cyclic check of all sub-class invoices (restaurant invoices, air tickets, accommodation tickets, etc.) in the reimbursement ticket and performs an action.

5. Dimension treatment: unifying all the variable dimensions to a standard unit (element) of the dimension (currency), and recording the original dimension unit of the variable; if the default unit of dimension of the pre-built model is seconds, but the unit in the rule is days, then it is converted to seconds. Thus, the number dimensions in the rule can be different from those in the database, and the correct result can be obtained.

6. Constructing a function statement: according to the rule format requirements of the corresponding computer language, the processed rule content is directly translated into the corresponding computer language, the rules are ordered according to the priority, and the higher the priority is, the later the rule is, and the corresponding rule statement is executed later. If the language is a compiling type language, executing a dynamic compiling program; if interpreted language, the steps are not needed.

The pre-processing rules are invoked in a stored format into a rules engine, in the form shown below:

if_condition_expression = "xmfp. Xmleixing=" research and development class "".

·or_condition_expression_list:"xmfp.jine<200yuan"

·action_expression_list:"bxd.bxjine＝200yuan"

Converting the above rule into a programming language according to a fixed format, for example, converting into a Java language, converting "=" into an equivalent () function, converting model attributes into model_get ("attribute value"), converting assignments into model_put functions, taking the above rule as an example, converting into the following Java language, compiling to obtain a Class binary file, and directly calling hardware by a virtual machine to calculate to obtain a result:

if (xmfp. Get ("xmleixing")) equal ("research and development class") |

xmfp.get("jine")<200){

bxd.put("bxjine",200)；}

7. Rule execution: and taking the processed input data as input parameters, injecting the input parameters into the constructed function statement, triggering an execution command to execute the constructed statement, and returning a result. Because the Chinese rule engines have good independence, when the data volume is large, the data can be grouped, and a plurality of rule engines can be called to complete tasks in parallel.

8. And D, dimension processing is carried out on the calculated result, so that the dimension in the calculation process is consistent, and if the dimension is inconsistent, the dimension conversion program is required to be called to process the dimension.

In a second aspect, referring to fig. 2, the present invention provides an implementation apparatus of a chinese business rule engine, including:

any two rules are selected as the first rule and the second rule,

repeating the steps until the conflict check of all rules is completed.
