Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to
Convenient for describing, only some but not all contents related to the present invention are shown in the drawings.
The scheme of embodiment to facilitate the understanding of the present invention first does lower letter to the basic knowledge of intelligent automatically request-answering system
It is single to introduce:
One, knowledge point
Basic knowledge point most original and simplest form in knowledge base are exactly usually common FAQ, general form
It is that " ask-answer " is right.For example, " rate of CRBT " are exactly that clearly standard asks description for expression.Here " asking " should not be by narrowly
It is interpreted as " inquiring ", and should broadly understand one " input ", being somebody's turn to do " input " has corresponding " output ".For example, for being used for
For the semantics recognition of control system, the instruction of user, such as " opening radio " should also be understood to be one
" asking ", corresponding at this time " answering " can be the calling for executing the control program accordingly controlled.
User to machine when inputting, the most ideal situation is that asked using standard, then the intelligent semantic identifying system of machine
At once it will be appreciated that the meaning of user.However, user often not uses standard to ask, but some deformations that standard is asked
Form.For example, if being " changing a radio station " for the standard form of asking of the radio station switching of radio, then user may make
Order is " switching one radio station ", and what machine was also required to can to identify user's expression is the same meaning.
Therefore, for intelligent semantic identification, the extension that the standard that needs in knowledge base is asked is asked, which asks and mark
Standard asks that expression-form has slight difference, but expresses identical meaning.
It therefore, include multiple knowledge points in knowledge base, each knowledge point includes problem and answer, and problem includes that standard is asked
It is asked with multiple extensions.
The problems in knowledge point generally indicates that here is the symbol in semantic formula with the form of semantic formula:
1.1.1 the expression ([]) of part of speech
To distinguish the word in expression formula with part of speech, it is specified that part of speech must be present in square brackets " [] ", occur in square brackets
Part of speech be generally " narrow sense part of speech ", but " broad sense part of speech " can also be supported by configuring system parameter.Here is some letters
The example of single expression formula: [Fetion] [how] [open-minded], [introduction] [multimedia message] [business], [login] [method] of [Fetion],
[call reminding] [how] [charge].
Or the expression (|) of relationship 1.1.2
Part of speech in square brackets can occur repeatedly by "or" relationship, and the part of speech of these "or" relationships can calculate
It is individually calculated in a manner of " expansion " when similarity." expansion " is mainly according to the meaning of "or" by semantic formula exhibition
It is split into the process of multiple structures.As: [CRBT] [open-minded] [method | step] it is deployable at " [CRBT] [open-minded]
[step] " and " [method] of [CRBT] [open-minded] " two simple semantic formulas.The example of this kind of semantic formula is such as
Under: [how] [inquiry | know] [PUK code], [quit the subscription of | revocation | close | deactivate] [IP | 17951] [the preferential packet of national distance].
1.1.3 it is non-essential indicate (?)
Part of speech in square brackets can be added at the end of "? " expression, which may occur in which, to be occurred, i.e., non-essential pass
System, the part of speech of this inessential relationship similarly can individually be calculated in a manner of " expansion " when calculating similarity." exhibition
Open " it is mainly that will be launched into include and do not include containing non-essential part of speech (or " or combination " of part of speech) in semantic formula
The process of the simple semantic formula of two of this part of speech.
Such as: [introduction] [mobile video] [military column] [content] [what? ] deployable at " [introduction] [mobile video]
[military column] [content] " and " [introduction] [mobile video] [military column] [content] [what] " two simple semantic meaning representations
Formula.
Two, ontology
Ontology (Ontology) is the Formal Representation to certain set concept and its mutual relationship among specific area,
It is the abstract to a field.We obtain the knowledge in a certain field using ontology, the concept in the ontology describing field,
And the relationship between these concepts.
The composition of 2.1 ontologies
Ontology includes ontology class and example, and ontology class defines the structure of corresponding example, and example is to meet ontology class to determine
The individual subject of justice.
2.1.1 ontology class (Ontology Class)
In real world, often has and belong to the object of same class (such as: certain automobile only many automobiles in the world
In one), also have the different objects of many shared same characteristic features.The same characteristic features that can use these objects are them
Establish a prototype.Ontology class (Ontology Class) is exactly a kind of definition of this prototype, it is to common trait
Or all individuals of shared common trait is abstract.The feature of ontology class is known as generic attribute (Class Property), such as
" people " this ontology class has attributes such as " names ", " age " and " weight ".Generic attribute is by attribute-name and one group of semantic formula institute
It constitutes.In ontology class, we can describe semanteme expressed by attribute, the semanteme of generic attribute with one group of semantic formula
Expression formula is made of example symbol, part of speech, grammatical symbol, and example symbol is for representing the part of speech or semantic chunk of description individual.
2.1.2 example (Instance)
Example is the product after the instantiation of ontology class, represents and meets the specific individual subject that ontology class defines.
Example is made of instance name, example semantic, attribute and attribute value.Example semantic: example semantic is for describing example semantic
Semantic formula, which replaces in ontology generic attribute semantic formula during instantiating ontology class
" example symbol ", and then generate the semanteme of instance properties.
Instance properties: instance properties include general property and Custom Attributes.General property is the ontology for instantiating example
Attribute defined in class, such as " car Santana " this example is that this ontology class instantiates to obtain by " car ", then " sedan-chair
The attributes such as " wheelbase " " weight " and " discharge capacity " are general property defined in this ontology class of vehicle ".Custom Attributes be in order to
A more complete description is individual and the customized feature for being appropriate only for the individual describes except general property.
Attribute value: attribute value, that is, attribute specific descriptions, the matter or amount of the attribute for exact expression example.Such as " male
Property " is exactly the attribute value of " gender " attribute in " Zhang San " this example.
Embodiment one
Fig. 1 is a kind of flow chart of the method for intelligent automatic question answering that the embodiment of the present invention one provides, and the present embodiment can fit
For searching the corresponding knowledge point of user request information for including the case where two examples, this method can be asked automatically by intelligence
The system answered executes, which can be realized by software and/or hardware, can be generally integrated in the equipment such as server, the party
Method specifically comprises the following steps:
Step 210, the original request message of user is received, the original request message includes that the first example and third are real
Example.
The original request message of user includes two examples, if original request message is " relationship of first and second ", wherein
First is the first example, and second is third example；Alternatively, first is third example, second is the first example.
Specifically, the original request message may include: the relationship of the first example and third example be what or first
Example and third example are what relationships etc..
Step 220, knowledge point corresponding with the original request message is searched in knowledge base by similarity calculation.
The semantic similarity for calculating the problem of storing in the original request message and knowledge base, will be calculated most
Big similarity is compared with preset first preset threshold, to search knowledge point corresponding with original request message.
Specifically, knowledge point packet corresponding with the original request message is searched in knowledge base by similarity calculation
It includes: calculating the semantic similarity for the problem of storing in the original request message and knowledge base, the maximum being calculated is similar
Degree is compared with preset first preset threshold, when the similarity being calculated is greater than first preset threshold, by this
The corresponding knowledge point of similarity is as the knowledge point searched；Otherwise, corresponding knowledge point is not found in knowledge base.
Step 230, when not finding corresponding knowledge point in knowledge base, according to the knowledge mapping pre-established, into
Row reasoning processing.
When the similarity being calculated is respectively less than the first preset threshold, determine in knowledge base without directly storage with it is initial
At this moment the corresponding knowledge point of solicited message can make inferences processing according to the knowledge mapping pre-established.The knowledge graph
Spectrum includes the incidence relation between multiple examples and example in knowledge base.
The reasoning is handled
Step 231, the first example is inquired in the knowledge mapping pre-established.
Specifically, knowledge mapping can be in table form to record the incidence relation between multiple examples.Carry out
When reasoning is handled, the first example is first looked for, to get the associated path of the first example Yu third example.
Step 232, associated path of first example in knowledge mapping is obtained, until the associated path includes
Third example.
Wherein, associated path is the path of multiple examples in association knowledge map, including at least two examples, and
The knowledge point of at least two examples is respectively included, a knowledge point includes problem and answer, and wherein problem includes an example,
It include another example in answer, the knowledge point that an example is respectively included in problem and answer is exactly to divide in problem and answer
The associated path for the example for not including.For example, the corresponding knowledge point of example 1 includes knowledge point 1.1,1.2 etc., knowledge point 1.1
Example 2 is quoted in answer, and the corresponding knowledge point of example 2 includes knowledge point 2.1,2.2 etc., and example 3 is quoted in the answer of knowledge point 2.2,
Then the incidence relation between example 1 and example 2 is the associated path of example 1 and example 2, which includes example 1, knows
Know point 1.1 and example 2, the incidence relation between example 1, example 2 and example 3 be the associated path of example 1 and example 3,
It include example 1, knowledge point 1.1, example 2, knowledge point 2.2 and example 3 i.e. in the associated path.
Step 233, answer is determined according to first example, third example and the associated path.
Each knowledge point only stores an attribute information between two examples, the association road in the present embodiment knowledge base
Diameter includes M attribute information, and M is greater than or equal to 2, to compensate for the defect that existing knowledge library only stores simple knowledge point.
Answer corresponding with the original request message of user can be determined according to the first example, third example and associated path
The answer is returned to the user by case.
Text answers both can be directly returned to user by the present embodiment, and text answers can also be converted to voice lattice
User is issued after formula, is not limited the scope of the invention.
For example, the original request message of user is " Huawei P9 be what relationship with Mr. Ren Zhengfei ", initial request letter
Include the first example " Huawei P9 " and third example " Mr. Ren Zhengfei " in breath, calculates in the original request message and knowledge base
The problem of semantic similarity, the similarity being calculated is respectively less than the first preset threshold, shows to search in knowledge base
To knowledge point corresponding with original request message, at this moment enter the reasoning process of knowledge based map: in the knowledge pre-established
It is inquired in map the first example " Huawei P9 ", obtains the associated path of the first example " Huawei P9 " in knowledge mapping, obtain
The process of associated path are as follows: there is knowledge point 1.1 and 1.2 in the corresponding knowledge point of the first example " Huawei P9 ", wherein knowledge point 1.1
The problem of be " what the CPU model of Huawei P9 is ", answer is the second example of reference " sea think kylin 955 ", then searches second
The corresponding knowledge point of example " sea think kylin 955 ", finds knowledge point 2.1, wherein the problem of " to think the production of kylin 955 in sea
Whom quotient is ", answer is to quote the 4th example " HiSilicon Technologies Co., Ltd. ", in the corresponding knowledge point of the 4th example not
Other examples are quoted, therefore do not find the associated path including third example " Mr. Ren Zhengfei "；Wherein knowledge point 1.2
The problem of be " whom the manufacturer of Huawei P9 is ", answer be reference the 5th example " Huawei Tech Co., Ltd ", the 5th example
There is knowledge point 5.1 in " Huawei Tech Co., Ltd " corresponding knowledge point, wherein for " Huawei Technologies are limited the problem of knowledge point 5.1
Whom the president of company is ", answer is reference third example " Mr. Ren Zhengfei ", which includes that third example " is appointed just
Non- Mr. ", i.e., including third example " Mr. Ren Zhengfei " associated path include the first example, knowledge point 1.2, the 5th example,
Knowledge point 5.1 and third example；Therefore, determine that answer is that " Ren Zhengfei is first according to the first example, third example and associated path
Life is the president of the manufacturer of Huawei P9 ", which is returned into user.
It include the in the original request message for another example the original request message of user is " first and second be what relationship "
One example " first " and third example " second ", calculate the semantic similarity of the problems in the original request message and knowledge base, calculate
Obtained similarity is respectively less than the first preset threshold, shows to find in knowledge base corresponding with original request message
At this moment knowledge point enters the reasoning process of knowledge based map: inquiring the first example in the knowledge mapping pre-established
" first " obtains the associated path of the first example " first " in knowledge mapping, obtains the process of associated path are as follows: the first example
" first " corresponding knowledge point has 1.1, is wherein the problem of knowledge point 1.1 " whom the former husband of first is ", and corresponding answer is reference the
The problem of two examples " third ", then inquire the corresponding knowledge point of the second example " third " and have 2.1, knowledge point 2.1 is " third existing female
Whom friend is ", corresponding answer is the 4th example " fourth " of reference, then inquires the corresponding knowledge point of the 4th example " fourth " and have 4.1,
The problem of knowledge point 4.1 is " whom the daughter of fourth is ", and answer is reference third example " second ", is found including third example " second "
Associated path, i.e., including third example " second " associated path include the first example " second ", knowledge point 1.1, the second example
" third ", knowledge point 2.1, the 4th example " fourth ", knowledge point 4.1 and third example " second "；Therefore, real according to the first example, third
Example and associated path determine that answer is " daughter that second is the existing girl friend of the former husband of first ", which is returned to user.
The technical solution of the present embodiment includes the first example and third example by the original request message in user, and
When cannot be searched in knowledge base to knowledge point corresponding with original request message by similarity calculation, according to pre-establishing
Knowledge mapping, make inferences processing, the reasoning processing includes: that the first example is inquired in the knowledge mapping pre-established,
Associated path of first example in knowledge mapping is obtained, until the associated path includes third example, it is real according to first
Example, third example and associated path determine answer, realize and find packet on the basis of not changing the knowledge point of knowledge base storage
