Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a schematic diagram of main steps of a method for managing a rule text according to an embodiment of the present invention.

As shown in fig. 1, a method for managing a rule text according to an embodiment of the present invention includes the following main steps:

s11: the server obtains the rule text and obtains a parameter object list required by the operation of the rule text.

After obtaining the parameter object list, putting the parameter object list into a Context (Context); and provides dynamic queries in context. The parameter list may be full, i.e. the parameter objects associated with the service are all put into context; it may also be dynamically specified, i.e. the corresponding parameter object is passed in by the upper invoker. A dynamic query method is generally provided in a context object, and a corresponding Value can be queried in a context through the dynamic query method by using a parameter keyword, i.e., Key, in a rule text. That is, the object entity is dynamically queried through the corresponding object entity identifier, and the context includes and uses the object entity, and the query is not included. And, the format of the context is set to Key-Value format, i.e. the format is [ Key, bean ]. The parameter list forms a set of Key and Value, and the corresponding Value can be obtained through the Key. Fig. 3 is a context entity of the system, that is, when the system executes a chinese rule, a mapping relationship of parameter object entity classes, such as [ Order, Order ] or [ key, value ], that needs to be prepared in advance, and a value corresponding to the next value, that is, a specific parameter entity class object, such as the next Order class and Sku class, can be obtained by the key, and these classes all include corresponding attribute fields, and the values of these attribute fields are needed to participate in the calculation when the rule is calculated.

S12: and splitting the rule text and converting the rule text into a word list. Performing Chinese and English binding and attribute binding on the vocabulary, and storing binding information in a database; and after the regular text is split, converting according to the binding information to obtain a word list. The binding is stored in a database, the database is inquired when the system is started, the database is loaded into a system memory, the Chinese regular text is divided into Chinese words, the Chinese word list is converted into an English word list for use, and then semantic analysis and other processes are carried out. The Chinese-English binding comprises binding of English words, phrases and symbols with Chinese, wherein the Chinese is a common language or a native language of a user, and the English represents a machine language, so that the binding of other common languages and the machine language is included in the technical scheme of the application. After binding Chinese vocabulary and English vocabulary, binding Chinese vocabulary and attributes, adopting a Chinese writing rule, and combining an application system, namely a server side, with dynamic analysis of a rule text, construction of a syntax tree, logic execution and the like, thereby realizing the Chinese writing and execution of the rule. As shown in FIG. 2, the predefined pool of system constants includes vocabulary bindings and property bindings, and these bindings information are stored in a database. The rule logic defines that English vocabulary of the definitions is predefined in the system, and the predefinition comprises system predefinition and self-predefinition. Like if, multi, the system predefines the processing logic defining if, i.e. the true/false decision on the following expression, the multiplication function, the multiplication calculation on the following values, etc. Self-predefining is the business person's own logical predefining of words. Data entity attribute binding is defined in Chinese for some data entities used by the system, for example, an order instance is defined as an order, an order amount is defined as order. And the entities can be added and maintained through a background management page.

S13: semantic analysis is performed on the word list. Semantically analyzing the word list further comprises: analyzing the word list, and judging whether words which are not subjected to semantic analysis exist in the word list; if not, ending; if yes, judging whether the word which is not subjected to semantic analysis is one of predefined words, predefined functions, constants, parameter classes and methods; if yes, designating the entity as a corresponding predefined entity, and adding the entity to the analysis word list; otherwise, an exception is thrown. The word analysis process is the word meaning analysis of words before the construction of a grammar tree, and the grammar tree is constructed on the basis of the analysis of each word meaning. In the embodiment of the invention, the method specifically comprises the following steps: step one, traversing a word list after the regular text is split, judging whether a word which is not subjected to semantic analysis exists, and if not, ending; if so, executing the second step; second, determine whether the word is a predefined vocabulary, such as: if yes, then appointing it as corresponding predefined entity, if not, then executing third step, judging if the word is predefined function, such as multiplication function, if yes, then appointing it as corresponding function entity, if not, then executing fourth step, judging if the word is constant, such as 300, 0.8, if yes, then appointing it as corresponding constant entity, if not, then executing fifth step, judging if the word is parameter class and method, such as order price, etc, greater than etc, if yes, then appointing it as corresponding object entity, if not, then executing sixth step, if none match predefined, then throw exception, predefined is logic of chain judgment, predefined judgment logic can be added into the chain, and the chain can be expanded at any time; and step seven, adding the predefined entities confirmed by the words into the word sense analysis list.

S14: and constructing a syntax tree according to the parameter object list and executing. As shown in fig. 4, a syntax tree is constructed according to the result of each word analysis, and the syntax tree is an arrangement of the execution order of the code segments to execute each branch of the syntax tree.

The syntax tree is actually a code branch tree, each part number is a code number branch, each branch is executed in sequence, each branch tree is executed according to the meaning of each keyword in the branch tree, for example, a method call of an object can be carried out according to the number of parameters of the method, a corresponding parameter key is obtained later, and then a corresponding value is obtained from Context through the parameter key to trigger the method; meanwhile, the result returned by the method is also put into the Context, so that the execution result of the previous code can be obtained when the following code is executed. The result of the syntax tree, e.g. the numbers in the first column, is performed in data from small to large, if there are two 2's, meaning that there are two branches below 1, which are performed in sequence, the latter branch may use the calculation result of the previous branch. The format in the syntax tree is [ word: type description type definition ], a word is a word decomposed in the code segment, the type description is a type indicating the word, the type definition is a variable or a static constant indicating the word if the word is processed, if the class is an object definition, the constant is a statement, and the parameter needs to be obtained from the Context.

Syntax tree branches are'; 'segmentation is performed, and then a syntax tree is constructed on the basis of word semantics, so as to' return multiplication (order amount, 0.8) if (order amount is more than 300); "is an example. After the word semantic analysis, ' if ' is analyzed to be ' if ', the following expression ' (the order amount is greater than 300) ' is subjected to true and false judgment, that is, ' the order amount ' corresponds to ' order. If true, the latter logical result, i.e., 'multiply (order amount, 0.8)' is returned, and 'multiply' corresponds to a function corresponding to 'multi', which needs to be binary multiplication or multiple multiplication, i.e., the following parameter lists are multiplied in sequence, and finally the result is returned, i.e., one branch execution is finished. CHILD _ EXPRESS in FIGS. 2-5 is a branch expression tag, i.e., a code branch; the METHOD _ CALL is a function CALL tag of a parameter object; ID is a parameter object tag; the CONST _ STRING and the CONST _ inter are constant tags, that is, the text in the rule is a constant or a constant in the parameter object. The FUNCTION _ CALL is a FUNCTION CALL tag, etc.
