Summary of the invention
The purpose of the present invention is to provide a kind of from demand text conversion to the conversion method of SysML demand figure.
The present invention is specific as follows:
Step 1: parsing to the natural language on demand text, the corresponding SD expression formula of demand text is obtained.
Step 2: SD expression formula obtained by step 1 is converted into ROM expression formula.
Step 3: the ROM expression formula that step 2 obtains is converted into SysML demand pel element.
3-1. is noun and verb according to part of speech to each syntactic constituent in demand text.
Verb is divided into following six class:
(1) derived class verb (Vj): the meaning of such verb expression is " succession ", including " succession ", " receiving "；
(2) class verb (V is verifiedy): the meaning of such verb expression is " verifying ", including " verifying ", " research "；
(3) improve class verb (Vg): the meaning of such verb expression is " improvement ", including " improvement ", " raising "；
(4) meet class verb (Vm): the meaning of such verb expression is " satisfaction ", including " satisfaction ", " realization "；
It (5) include class verb (Vb): the meaning of such verb expression is "comprising", including "comprising" " comprising ".
(6) other class verbs (Vq): such verb is the verb other than the above five classes verb.
Demand in SysML demand figure is divided into three classes by 3-2.: " major demands ", " functional requirement " and " sub- demand ".With
There are that most nouns of the quantity of relationship to be used as " major demands " with other syntactic constituents in ROM expression formula.
If there is " including class verb " in 3-3. one sentence containing " major demands ", and exist and " major demands "
Relationship is the noun of " Constraint ", then the relationship using this with " major demands " is the noun of " Constraint " as " function
Energy demand ".
If there is " derived class verb " in 3-4. one sentence containing " functional requirement ", and exist and " functional requirement "
Relationship is the noun of " Constraint ", then should with noun that the relationship of " functional requirement " is " Constraint " as first to
Name word.If only having first noun undetermined in a sentence, which is used as " sub- demand ".If a sentence
There are the multiple first nouns undetermined in son, then judge the relationship of each first noun undetermined between any two in the sentence respectively, will be with
The first noun undetermined that other first nouns undetermined have " Connection " relationship in the sentence is used as " sub- demand ".
If there is " improving class verb " in 3-5. one sentence containing " sub- demand ", and there is the relationship with " sub- demand "
For the noun of " Constraint ", then should with noun that the relationship of " sub- demand " is " Constraint " as second wait name
Word.If one " sub- demand " only corresponds to second noun undetermined, which is used as " use-case ".If " a son
Demand " is corresponding with the multiple second nouns undetermined, then judgement is somebody's turn to do " sub- demand " corresponding each second noun undetermined between any two respectively
Relationship, regard the second noun undetermined that there are " Connection " relationships with other second nouns undetermined as " use-case ".
If there is " meeting class verb " in 3-6. one sentence containing " sub- demand ", and there is the relationship with " sub- demand "
For the noun of " Constraint ", then should wait naming as third with the noun that the relationship of " sub- demand " is " Constraint "
Word.If only corresponding to a third noun undetermined in one " sub- demand ", third noun undetermined is used as " module ".If a son
Demand corresponds to multiple thirds noun undetermined, then judgement should the pass of " sub- demand " corresponding each third noun undetermined between any two respectively
System regard the third noun undetermined that there is " Connection " relationship with other second nouns undetermined as " module ".
If there is " verifying class verb " in 3-7. one sentence containing " functional requirement ", and exist and " functional requirement "
Relationship is the noun of " Constraint ", then should be undetermined as the 4th for the noun of " Constraint " with the relationship of functional requirement
Noun.If only having the 4th noun undetermined in a sentence, the 4th noun undetermined is used as " test cases ".If a sentence
There are multiple 4th nouns undetermined in son, then the relationship of each 4th noun undetermined between any two in the sentence is judged, it will be with other
The 4th noun undetermined that 4th noun undetermined has " Connection " relationship is used as " test cases ".
Step 4: the SysML demand pel element that step 3 obtains is integrated into SysML demand figure.
Each SysML demand pel element that 4-1. obtains step 3 is respectively put into frame.It will be each " functional requirement " and " main
Demand " is connected with cross-hair.
4-2. will each " functional requirement " it is connected with straight line with the arrow respectively with corresponding " sub- demand ", and " function need to owning
Ask " and " sub- demand " between straight line with the arrow on mark " deriveReqt ".
Each " functional requirement " is connected with straight line with the arrow by 4-3. respectively with corresponding " test cases ", and in all " functions
" verify " is marked on straight line with the arrow between demand " and " test cases ".
4-4. will each " sub- demand " it is connected with straight line with the arrow respectively with corresponding " use-case ", and in all " sub- demands " and
" refine " is marked on straight line with the arrow between " use-case ".
4-5. will each " sub- demand " it is connected with straight line with the arrow respectively with corresponding " module ", and in all " sub- demands " and
" satisfy " is marked on straight line with the arrow between " module ".

Step 1: being SD expression formula by the demand text conversion based on product.
After obtaining the demand text based on product, using Stanford Parser syntax analytical tool, to natural language into
Row Preliminary Analysis matches grammer corresponding with the structure of demand text in Stanford Parser syntax analytical tool.Later
Demand text is converted construction syntax tree by Stanford Parser syntax analytical tool, and obtains the corresponding SD of demand text
Expression formula.Contain in demand text in every each sentence in SD expression formula, a mutual relationship (i.e. sentence for each syntactic constituent
All there is relationship between any two " word " in son, and belong between " word " of two different sentences that there is no relationships).
Step 2: establishing SD expression formula to ROM expression formula by the way that SD relationship and ROM relationship are compared and are analyzed
Mapping ruler collection is as shown in table 1.Later, according to the mapping ruler collection of SD expression formula to ROM expression formula, by SD table obtained by step 1
ROM expression formula (i.e. recurrence object model) is converted into up to formula；
Mapping ruler collection table 1 of the SD expression formula to ROM expression formula
Mapping relations are mutually of with the ROM expression formula of a line and SD expression formula in table 1.Such as, the SD of two level syntaxes
Expression formula is " amod ", then the ROM expression formula of two level syntaxes is Constraint.
Recurrence object model (ROM) is a kind of graphical language in industrial design demand analysis field.ROM is with mathematics
Based on, derived from the axiomatic theory to design a model, formed in conjunction with the language construction of English.ROM by object and be related to this two
Part forms.Object includes basic object and composite object, and it is the constraint relationship, connection relationship and meaning respectively that relationship, which includes three kinds,
Word relationship.The constraint relationship is descriptive between an object and another object, restrictive or particularity relationship.Even
The relationship of connecing is that there is no limit relationships between two objects, is the relationship of equality.Predicate relationship is that another is right for an object factory
The behavior of elephant, or the relationship of the state of another object is described.
Step 3: establishing mapping ruler.The ROM expression formula that step 2 is formed is converted into SysML need according to mapping ruler
Ask pel plain；
3-1. is noun and verb according to part of speech to each syntactic constituent in demand text.Noun is divided into following three classes:
(1) " mankind " noun (Nh): the class noun describes the identity of the mankind, including " administrator ", " designer ", " operation
Person ".
(2) non-demand noun (Nn): the class noun is the noun that can not be defined as demand or module, is abstract noun
Or the noun in expression orientation will ignore this class noun, including " justice ", " distant place " or " a left side when generating demand pel element
It is right ".
(3) regular noun (Nr): the noun other than " mankind " noun and non-demand noun.
Verb is divided into following seven class:
(1) derived class verb (Vj): the meaning of such verb expression is " succession ", including " succession ", " receiving "；
(2) class verb (V is verifiedy): the meaning of such verb expression is " verifying ", including " verifying ", " research "；
(3) improve class verb (Vg): the meaning of such verb expression is " improvement ", including " improvement ", " raising "；
(4) meet class verb (Vm): the meaning of such verb expression is " satisfaction ", including " satisfaction ", " realization "；
(5) class verb (V is trackedz): the meaning of such verb expression is " tracking ", including " tracking ", " offer "；
It (6) include class verb (Vb): the meaning of such verb expression is "comprising", including "comprising" " comprising ".
(7) other class verbs (Vq): such verb is the verb other than the above six classes verb, is occurred in use very
It is few, it is general negligible.
3-2. establishes part of speech and the mapping table of demand figure element type is as shown in table 2.
The mapping table table 2 of part of speech and demand figure element type
Demand in SysML demand figure is divided into three classes: " major demands ", " functional requirement " and " sub- demand ".Mainly need
Total demand of Seeking Truth product design；Functional requirement is the demand of the function to be realized of the product；Sub- demand is to realize
The demand of each piecemeal required for functional requirement.
There are that most nouns of the quantity of relationship as " major demands " with other syntactic constituents using in ROM expression formula
(syntactic constituent present in different sentences, relationship quantity are the summation of relationship quantity in each sentence.Such as judge noun " A "
Relationship quantity when, just calculate in the sentence in demand text where each noun " A ", the syntactic constituent in addition to noun " A "
Quantity, the method composition quantity are exactly relationship quantity of the noun " A " in the sentence.By each containing noun " A " in noun " A " sentence
Relationship quantity be added, be exactly the total relationship quantity of noun " A ".
