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 just Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.

It also should be noted that only the parts related to the present invention are shown for ease of description, in attached drawing rather than Full content.It should be mentioned that some exemplary embodiments are described before exemplary embodiment is discussed in greater detail At the processing or method described as flow chart.Although operations (or step) are described as the processing of sequence by flow chart, It is that many of these operations can be implemented concurrently, concomitantly or simultaneously.In addition, the sequence of operations can be by again It arranges.The processing can be terminated when its operations are completed, it is also possible to have the additional step being not included in attached drawing. The processing can correspond to method, function, regulation, subroutine, subprogram etc..

The content of embodiment to facilitate the understanding of the present invention first introduces question and answer knowledge point and language in intelligent answer The related notion of adopted expression formula is simply introduced:

1, question and answer knowledge point

Question and answer 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 for asking of standard Form.For example, if being " changing a radio station " for the standard form of asking of the radio station switching of radio, then what user may use Order is " switching one radio station ", and what machine was also required to can to identify user's expression is the same meaning.

For intelligent semantic identification, the extension that the standard that needs in knowledge base is asked is asked, which, which asks, asks table with standard There is slight difference up to form, but expresses identical meaning.

It therefore, include multiple question and answer knowledge points in knowledge base, each question and answer knowledge point includes problem and answer, and problem includes Standard, which is asked, asks that the problems in question and answer knowledge point shows generally by the form of semantic formula with multiple extensions.

2, semantic formula

Semantic formula is mainly made of word, part of speech and their "or" relationship, and core depends on " part of speech ", part of speech Simple to understand to be one group of word for having general character, these words can be similar or dissimilar semantically, these words can also be with It is noted as important or inessential.Semantic formula and user's question sentence relationship and traditional template matching have very big difference, In conventional template matching, template and user's question sentence are only matched and not matched relationship, and semantic formula and user's question sentence Between relationship be indicated by the value (similarity) of quantization, while this quantization value between similar question sentence and user's question sentence Similarity can mutually compare.Since semantic formula will participate in together similarity calculation with similar question sentence, so mould The definition of plate grammer is unsuitable complicated, but has enough ability expression semantic again.

In addition, giving the device of the more wheel question answering systems of modification in various embodiments of the present invention, wherein more wheels are asked The system of answering specifically includes:

It is corresponding with more wheel question and answer flow charts to take turns question and answer process module more, it include multiple figures in more wheel question and answer flow charts Shape component, the graphic assembly include: multiple interaction nodes；

The thematic knowledge point being stored in the knowledge base, the thematic knowledge point include problem of subject and theme answer, The problem of subject is used to indicate the trigger condition with the matched more wheel question and answer process modules of more wheel question answering systems, the master Topic answer is used to establish the triggering relationship of the thematic knowledge point and more wheel question and answer process modules.

In order to make it easy to understand, the generating means of above-mentioned more wheel question answering systems are simply introduced first.

Shown in Fig. 1 a, the generating means of more wheel question answering systems specifically include: more wheel question and answer flow charts obtain module 110, standardized codes frame generation module 120, custom code adding module 130, corresponding relation building module 140 and Main body knowledge point adding module 150, in which:

More wheel question and answer flow charts obtain module 110, and for obtaining, patterned one or more takes turns question and answer flow chart.

Wherein, more wheel question and answer flow chart specifically can be selection and combine provided in setting process editing interface it is each A graphic assembly, obtained patterned flow chart.

Wherein, graphic assembly may include node and the connector (typical, connecting line) for connecting different nodes. It include interaction node in the node, the interaction node specifically refers to that question and answer can have been carried out with interactive user (can to ask with one One answers, and can also ask answer with one more) node of interaction, under the interaction node, the customer interaction information that can be inputted according to user, Determine next trend of more wheel question and answer flow charts.

For the overall structure of more wheel question and answer flow charts, it may include having a root node that question and answer flow chart is taken turns one more The beginning of process is represented, one or more terminal nodes represent the end of process.In addition, can also mostly be wrapped in wheel question and answer flow chart Multilayer interaction node is included, every layer of interaction node includes one or more interaction nodes.Wherein, one layer of interaction node, it is one corresponding The question and answer stage.

It is, of course, understood that the node other than it may include interaction node, can also include casting section Node or recording node etc. is arranged in point, variable, and the present embodiment is not limited thereto, and in general, question and answer is taken turns one more Root node in flow chart is interaction node, and terminal node is casting node.

In order to make it easy to understand, showing a kind of patterned more wheel question and answer flow charts in Figure 1b.As shown in Figure 1 b, described The graphic assemblies of diamond shape are interaction node (such as: inquiry age node 101), rectangular graphic assembly in more wheel question and answer flow charts For casting node (such as: the age is unsatisfactory for terms of loan node 102).Pass through the connecting line of node-to-node between each node It is connected.It wherein, include four layers of interaction node in more wheel question and answer flow charts described in Fig. 1 b.It include an interaction in each layer Node, namely: include: inquiry age node 101 (root node) in first layer, represents the inquiry stage at age, the second layer includes asking It asks the node 103 that whether has car and house, represents the garage inquiry stage, third layer includes the node 106 for inquiring the amount of the loan, representative loan The money amount of money inquires that stage and the 4th layer include inquiry several sections of points 107 by stages, represents and counts the inquiry stages by stages.Each interaction It can accordingly determine that more the different of wheel question and answer flow chart are moved towards according to the different interaction contents of input in node.In addition, this is more Taking turns question and answer flow chart includes multiple terminal nodes, namely: the age is unsatisfactory for terms of loan node 102, reminds excess node 109, oversubscription issue node 108 and casting loan result node 10A by stages are reminded.

Standardized codes frame generation module 120, for according to each figure for including in each more wheel question and answer flow charts Shape component generates and more wheel matched standardized codes frames of question and answer flow chart, wherein the graphic assembly includes: more A interaction node.

Therein it is proposed that a kind of more wheel question and answer process modules that can be automatically generated.Correspondingly, being provided previously and inhomogeneity The standard implementation code that type graphic assembly matches, such as: establish standard corresponding with interaction node and casting node Realization code wrap pre-establishes the corresponding pass between standard implementation code and corresponding graphic assembly in different library files System.Typically, it can be previously written in the process editing interface and realize code with the matched standardization of each graphic assembly Storage address (or reference address), correspondingly, can be for the more wheel question and answer processes drawn based on the process editing interface Each graphic assembly for including in figure, the automatic corresponding matched standardized codes frame of generation.

It should be noted that the embodiment of the present invention concern is primarily with taking turns the generating means of question answering system more, it is therefore, take turns more It may include having multiple interaction nodes in question and answer flow chart, still, the technical solution of the embodiment of the present invention theoretically may be implemented Corresponding standardization generation can be obtained as long as drawing corresponding flow chart as needed in the generation of any kind of question answering system Code frame, and corresponding process module is obtained in turn.

Custom code adding module 130, for basis and each graphic assemblies in more wheel question and answer flow charts It is matched to custom-configure information, it generates custom code corresponding with each graphic assembly and makes an addition to the standardization In code skeleton and at the associated position of graphic assembly, to generate mostly wheel question and answer processes corresponding with more wheel question and answer flow charts Module.

It is understood that only including corresponding graphic assembly with the matched standard implementation code of each graphic assembly The general utility functions that can be realized.Such as: it is directed to an interaction node, includes decision logic in corresponding standard implementation code, Or it is directed to a casting node, it include casting logic etc. in corresponding standard implementation code.In order to enable a graphical set Part can be realized the functions that it is assigned in more wheel question and answer flow charts, needs to input and custom-configures parameter accordingly.

It cites a plain example, is unsatisfactory for terms of loan node 102 for the age in Fig. 1 b, the age is needed to be unsatisfactory for Terms of loan node 102 in a triggered, can broadcast content " age is unsatisfactory for the terms of loan ", correspondingly, above-mentioned, " age is not Meet the terms of loan " it is exactly the function that the imparting of terms of loan node 102 is unsatisfactory for the age, in order to enable the age is unsatisfactory for providing a loan Condition node 102 can be realized above-mentioned function, need that the standard is added using above-mentioned casting content as information is custom-configured Change in code skeleton.

Typically, blank code can be reserved with the setting position in the matched standard implementation code of each graphic assembly Section is being obtained for the graphic assemblies input in more wheel question and answer flow charts when custom-configuring parameter (for example, passing through stream The parameter configuration interface input that journey editing interface provides), the matched custom code addition pair of parameter is custom-configured by described In the blank code segment answered, to realize customized graphic assembly function.

Optionally, information (such as: the age is unsatisfactory for the terms of loan) can will be custom-configured to make by oneself directly as described Adopted code makes an addition in the standardized codes frame, (can also preferentially select for example, opening rejection according to information is custom-configured Item opens knowledge priority option), what matching was write in advance adds from the different custom codes for custom-configuring information matches It is added in the standardized codes frame, the present embodiment is to this and is not limited.

Correspondingly, if completing customized set to the whole graphic assemblies for including in question and answer flow chart are taken turns one more It sets, then the realization code that can be realized more wheel question and answer flow chart functions can be generated, namely: generate institute of the embodiment of the present invention The more wheel question and answer process modules stated.

Corresponding relation building module 140, for establishing one or more knowledge in each interaction node and knowledge base The corresponding relationship of point, knowledge point corresponding with the interaction node include: interaction problems and interaction answer, and the interaction problems are used It is matched in the customer interaction information received, the interactive answer is for determining under more wheel question and answer process modules One trend.

Wherein, interaction node needs to determine the next of the more wheel question and answer process modules established according to customer interaction information Trend.Namely: interaction node includes at least two branches, and the difference that different branches correspond to more wheel question and answer process modules is walked To.Therefore, it is necessary to be the different branch condition of different branch establishings in more wheel question and answer process modules, such as: such as Fig. 1 b institute Show, on inquiry age node 101, if it is determined that customer interaction information is " having reach 20 years old ", then to take turns question and answer process module edge more Branch A circulate to asking whether this trend of node 103 that has car and house, if it is determined that customer interaction information is " less than 20 Year ", then more wheel question and answer process modules can circulate along branch B is unsatisfactory for this trend of terms of loan node 102 to the age.

In fact, interactive user (namely: the user that question and answer interact is carried out with more wheel question answering systems) in an interaction node The expression-form of the customer interaction information of lower input may be not unique, and customer interaction informations multiple and different in other words can be with The corresponding same branch condition.It as in the previous example, for example, can be with prespecified customer interaction information for " having reach 20 years old ", " adult " Or when " meeting age condition ", question and answer process modules of taking turns can circulate more along branch A, then in addition to (connecting branch A Part) Dynamic trigger condition setting be " reach 20 years old " except, it is also necessary in knowledge base establish and the matched friendship of interaction node Mutual knowledge point: (having reach 20 years old, completely 20 years old), (having grown up, completely 20 years old) and (meeting age condition, completely 20 years old).And Above-mentioned interactive knowledge point is established respectively and inquires the corresponding relationship of age node 101.Similarly, for " less than 20 years old " this point Branch, it is also desirable to be established in knowledge base and interaction node is matched interacts knowledge point: (less than 20 years old, less than 20 years old), (not at Year, less than 20 years old) and (be unsatisfactory for age condition, less than 20 years old).Therefore, inquiry age node 101 altogether need to be with six interactions Corresponding relationship is established in knowledge point.It is understood that knowledge point corresponding with interaction node and question and answer knowledge in the prior art It is distinguishing for putting, and therefore, for the ease of difference, knowledge point corresponding with interaction node is known as interaction knowledge point hereinafter.

Wherein, first half in each bracket represents the interaction problems of interaction knowledge point, for the user that receives Interactive information is matched, and the latter half in each bracket represents the interaction answer of the interaction knowledge point, described in determining Next trend of more wheel question and answer process modules.

By aforesaid operations, when mostly wheel question and answer process modules circulate to the inquiry age node 101, no matter interactive user Input " having reach 20 years old " still " has been grown up ", and " having reach 20 years old " this interaction answer can be matched in knowledge base, is being obtained After taking " having reach 20 years old " this interaction answer, question answering systems of taking turns can determine the dynamic contact of the interaction answer and branch A setting more Clockwork spring part matches, then more wheel question and answer process modules continue circulation downwards by branch A.

Need it is once more emphasized that, the interactive knowledge point corresponding with interaction node stored in the knowledge base be different from institute The question and answer knowledge point stored in knowledge base is stated, as previously mentioned, so-called question and answer knowledge point, generally comprises problematic and corresponding answers Case (alternatively referred to as " ask-answer " to), wherein the question and answer knowledge point is primarily adapted for use in the scene that question and answer are carried out with interactive user In, the problems in question and answer knowledge point with the customer interaction information of interactive user for being matched, if successful match, to the friendship Answer in mutual user feedback question and answer knowledge point, or execute the calling with the control program of the answer content matching.

Namely: question and answer knowledge point can directly determine interaction process result corresponding with customer interaction information (for example, feedback Answer content or the calling for executing setting control program), and interacting knowledge point is the branch for determining more wheel question answering systems Condition, the two purposes is different.For the ease of being distinguished in different application scene to above-mentioned two class knowledge point, can will hand over Mutual knowledge point and question and answer knowledge point are stored at storage location different in the knowledge base, or are added in interaction knowledge point Add the knowledge point label etc. distinguished with question and answer knowledge point.

In fact, the main purpose that interaction knowledge point is arranged allows for the user received for same interaction node The content of interactive information may be diversified, for example, " reach 20 years old " described in precedent or " adult " etc., still, In order to guarantee to take turns the terseness of question answering system one, generally when a branch condition of interaction node is arranged, being used only single more One conditional content, such as: " having reach 20 years old " therefore introduces the concept of interactive knowledge point.It is same by being directed in knowledge base Multiple interactive knowledge points are arranged in the same branch condition of one interaction node, namely: by multiple distinct interactions for being directed toward same branch Problem, the same interactive answer in correspondence, can be realized and allow multiple approximate expression contents that can correspond to a branch condition.

In other embodiments of the invention, question and answer knowledge point with interact knowledge point not it is also possible to not to the two It distinguishes, all within protection scope of the present invention.

As in the previous example, take turns one in question and answer process module may include multiple connectors to connect different nodes more, therefore, Information can be custom-configured by configuring the target connector that one is used to connect upper layer interaction node and lower level node, Realize the determination of next trend to more wheel question and answer process modules.

Correspondingly, the information that custom-configures may include: and the matched dynamic condition configuration information of target connector； The target connector is interaction section for connecting association upper layer node and association lower level node, the association upper layer node Point；

Wherein, the dynamic condition configuration information is that more wheel question and answer process modules circulate from the association upper layer node To the condition of the association lower level node, the dynamic condition configuration information and the association upper layer node in the knowledge base Interaction answer in a corresponding knowledge point matches.

Main body knowledge point adding module 150, for the addition in knowledge base and each more wheel question and answer process modules pair The thematic knowledge point answered, the thematic knowledge point include problem of subject and theme answer, and the problem of subject is taken turns more for indicating The trigger condition of question and answer process module, the theme answer is for establishing the thematic knowledge point and more wheel question and answer process moulds The triggering relationship of block.

Wherein, more wheel question and answer process modules (code for realizing more wheel question and answer flow charts) is being generated, and in knowledge base It establishes after interaction node and the corresponding relationship of one or more knowledge point, in order to realize to more wheel question and answer process modules Normal use, needs further that addition with each described takes turns the corresponding thematic knowledge point of question and answer process module more in knowledge base.

It should be noted that foregoing present one kind to firstly generate more wheel question and answer process modules, theme is established later The implementation of knowledge point, and it will be appreciated by persons skilled in the art that the establishment process of thematic knowledge point can not office It is limited to execute after generating more wheel question and answer process modules, is not defined here.For example, thematic knowledge can be initially set up Point is establishing corresponding more wheel question and answer process modules etc. later.

In fact, thematic knowledge point and the difference of the question and answer knowledge point in knowledge base are: when the use of interactive user input When the problems in family interactive information and question and answer knowledge point match, can directly export the answer of the question and answer knowledge point, or execute with The calling of the control program of the answer content matching, and when the customer interaction information of interactive user input (is referred to as just hereinafter Beginning solicited message) when being matched with the problem of subject of a thematic knowledge point, then it can correspond to and trigger more wheel question and answer process module (examples Such as, the root node of more wheel question and answer process modules is directly triggered).

Typically, the theme answer in a thematic knowledge point can be the corresponding more wheel question and answer processes of the thematic knowledge point The information of more wheel question and answer process modules can be accurately positioned in storage address or call address of module etc..

Foregoing present a kind of generation of more wheel question answering systems that can be realized by way of What You See Is What You Get dresses It sets, optimizes the implementation of existing more wheel question answering systems, realize rapid build and the update of more wheel question answering systems, keep away Exempt to introduce developer in more wheel question answering system generating process, greatly reduced the workload of developer, reduce costs, Improve accuracy rate and efficiency.

Specifically, the information that custom-configures may further include: rejection priority option corresponding with interaction node.

Wherein, it circulates in more wheel question and answer process modules to configuration and opens the first interaction node of rejection priority function When, if it is determined that the customer interaction information received at least one knowledge corresponding with first interaction node in knowledge base Interaction problems in point mismatch, then provide rejection response, and the customer interaction information is re-entered in request.

Namely: if an interaction node is configured for rejection priority option, identification base is only capable of in the interaction node In the interaction problems of the interaction node.Typically, it is refused if be provided with for an interaction nodes for taking turns question and answer flow charts more Know priority option, then obtain write in advance with the matched custom code of rejection priority function, and by above-mentioned custom code It makes an addition in the standardized codes frame and at the associated position of the interaction node.

By the way that rejection priority option is arranged, it ensure that more wheel question answering systems can be held according to pre-designed process sequence Row arbitrarily will not be jumped or be fed back because of some unrecognized problems of more wheel question answering systems that user inputs, So that regular, the secondary sequence of entire more wheel question answering systems is more preferable.

Unlike rejection priority option, the information that custom-configures can also include: corresponding with interaction node Knowledge priority option；

Wherein, it circulates in more wheel question and answer process modules to configuration and opens the second interaction node of knowledge priority function When, if it is determined that received customer interaction information at least one knowledge point corresponding with second interaction node in knowledge base In interaction problems mismatch, then global search is carried out to the customer interaction information in the knowledge base, and according to complete Office's lookup result executes corresponding interactive operation.

Namely: if an interaction node is configured for knowledge priority option, base is identified first in the interaction node In the interaction problems of the interaction node, if recognition failures, will continue to identify problem in other knowledge points in knowledge base.Allusion quotation Type, if being provided with knowledge priority option for an interaction node of more wheel question and answer flow charts, acquisition is write in advance With the matched custom code of knowledge priority function, and above-mentioned custom code is made an addition in the standardized codes frame At the associated position of the interaction node.

By the way that knowledge priority option is arranged, it ensure that the execution flexibility of more wheel question answering systems, can be handed over determining user When mutual information is mismatched with the node currently to circulate, also question and answer can be carried out with user well and interacted, to further increase user Satisfaction.

In a specific example, for the corresponding more wheel interactive systems of flow chart of such as Fig. 1 b, for the inquiry age 101 this interaction node of point are corresponding with 6 interactive knowledge points, and the interaction problems of this 6 interactive knowledge points are respectively " to have expired 20 Year ", " adult ", " meeting age condition ", " less than 20 years old ", " teenage " and " not meeting age condition ", when input When customer interaction information and above-mentioned 6 interaction problems mismatch, such as: " today, weather was how ", if the inquiry age Node 101 is provided with rejection priority option, then more wheel question answering systems will not provide corresponding feedback for the customer interaction information, And it rests on and inquires that continuing waiting for user on age node 101 re-enters new interactive information；If the inquiry age node The problem of 101 are provided with knowledge priority option, then more wheel question answering systems can be searched in knowledge base with the inquiry weather is corresponding Question and answer knowledge point, and the answer of the question and answer knowledge point is fed back.

Specifically, the information that custom-configures can further include: back track function choosing corresponding with interaction node ?；

Wherein, when more wheel question and answer process modules circulate and open the third interaction node of back track function to configuration, such as Fruit determines the interaction problems of received customer interaction information upper layer node corresponding with the third interaction node in knowledge base Match, then more wheel question and answer process modules circulates upper layer node corresponding to the third interaction node.

By the way that back track function is arranged, the versatility for more taking turns question answering system can be made stronger, in mostly wheel question answering system and used Family carries out in question and answer interactive process, and the content that can be inputted at any time according to user readjusts walking for entire more wheel question answering systems To being re-executed especially it is possible to return to the interaction node executed to one, and redefine based on the interaction Next trend of node, to better meet practical more wheel question and answer demands of user.

In a specific example, for the corresponding more wheel interactive systems of flow chart of such as Fig. 1 b, for the inquiry age Point 101, user has input " less than 20 years old " this customer interaction information, correspondingly, more wheel question answering systems are circulated by branch B It is unsatisfactory for terms of loan node 102 to the age, and plays corresponding casting content to user.At this point, if user re-enters " having reach 20 years old " this customer interaction information, then more wheel question answering systems can circulate (backtracking) to inquiring age node 101 again, and According to the above content that user inputs, question answering systems of taking turns circulate again through branch A to asking whether the node 103 that has car and house more Continue to interact with user's progress question and answer.

Specifically, the graphic assembly can further include: casting node.Correspondingly, described custom-configure letter Breath may include: casting content corresponding with node, and the node includes: interaction node and casting node；

Wherein, if more wheel question and answer process modules circulate to the fourth node configured with casting content, correspondence is broadcast Report casting content corresponding with the fourth node.

In a specific example, as shown in Figure 1 b, when mostly wheel question answering systems circulate to asking whether the node that has car and house When 103 this interaction node, which can broadcast preset casting content first, for example, " may I ask whether you have vehicle Have room ", next trend of more wheel question answering systems can be determined based on the customer interaction information of receipt of subsequent later；When more wheel question and answer systems To when meeting this casting node of 200,000 terms of loan, which can directly be broadcasted in preset casting for system circulation Hold, such as: " you meet 200,000 terms of loan ".

Content is broadcasted by setting, effective question and answer can be carried out with user and interacted, and user can be needed in next step The interaction content of input is effectively prompted.

Specifically, the information that custom-configures can further include: corresponding with node to interrupt function choosing-item；
