Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

In order to facilitate understanding of the content of the embodiment of the invention, question-answer knowledge points in intelligent question-answers and related concepts of semantic expressions are introduced for simple introduction:

1. question-answering knowledge point

The most primitive and simplest form of question-answer knowledge points in the knowledge base is the frequently used FAQ in normal times, and the general form is a question-answer pair. For example, "the tariff for a coloring ring back tone" is a clear description of the standard. The term "question" should not be construed narrowly as "question" but rather broadly as "input" with corresponding "output". For example, for semantic recognition for a control system, an instruction of a user, for example "turn on radio", should also be understood as a "question", in which case the corresponding "answer" may be a call to a control program for executing the corresponding control.

When the user inputs the information to the machine, the most ideal situation is to use standard questions, and the intelligent semantic recognition system of the machine can immediately understand the meaning of the user. However, rather than using standard questions, users often use some variant form of standard questions. For example, if the standard form of a station switch for a radio is "change station", then the command that the user may use is "switch station", and the machine also needs to be able to recognize that what the user has expressed is the same meaning.

For intelligent semantic recognition, an expanded question of a standard question is required in the knowledge base, and the expanded question is slightly different from the expression form of the standard question but expresses the same meaning.

Therefore, the knowledge base comprises a plurality of question-answer knowledge points, each question-answer knowledge point comprises a question and an answer, the question comprises a standard question and a plurality of expanded questions, and the questions in the question-answer knowledge points are generally represented in the form of semantic expressions.

2. Semantic expression

The semantic expression mainly comprises words, parts of speech and their or relations, the core of the semantic expression depends on the parts of speech, the simple understanding of the parts of speech is a group of common words, the words can be similar or dissimilar in semantics, and the words can be marked as important or unimportant. The semantic expression and user question relationship is very different from the traditional template matching, in which the template and user question are just matching and unmatching relationships, and the relationship between the semantic expression and user question is represented by a quantized value (similarity), and the quantized value and the similarity between the similar question and the user question can be compared with each other. Because the semantic expression and the similar question sentence participate in similarity calculation, the definition of the template grammar is not complex, but enough ability to express the semantic is required.

In addition, in each embodiment of the present invention, a method for modifying a multi-turn question-answering system is provided, wherein the multi-turn question-answering system specifically includes:

a plurality of rounds of question-answering flow modules corresponding to a plurality of rounds of question-answering flow charts, wherein the plurality of rounds of question-answering flow charts comprise a plurality of graphic assemblies, and the graphic assemblies comprise: a plurality of interactive nodes;

the topic knowledge points are stored in the knowledge base and comprise topic questions and topic answers, the topic questions are used for representing trigger conditions of the multiple rounds of question-answering flow modules matched with the multiple rounds of question-answering systems, and the topic answers are used for establishing trigger relations between the topic knowledge points and the multiple rounds of question-answering flow modules.

For ease of understanding, the generation method of the multi-turn question-answering system will be briefly described first.

As shown in fig. 1a, the method for generating the multi-turn question-answering system specifically includes:

and S110, acquiring one or more graphical multi-turn question-answer flow charts.

The multiple rounds of question answering flow charts can be graphical flow charts obtained by selecting and combining various graphical components provided in a set flow editing interface.

Wherein a graph component may comprise nodes and connectors (typically connecting lines) for connecting different nodes. The nodes comprise interactive nodes, the interactive nodes are specifically nodes which can interact with interactive users in a question-answer mode (either a question-answer mode or a question-answer mode), and the next trend of a multi-turn question-answer flow chart can be determined according to user interaction information input by the users under the interactive nodes.

From the overall structure of the multi-round question-answering flow chart, a multi-round question-answering flow chart can comprise a root node representing the beginning of the flow and one or more termination nodes representing the end of the flow. In addition, multiple layers of interactive nodes can be included in the multi-turn question-answering flow chart, and each layer of interactive nodes comprises one or more interactive nodes. Wherein, one layer of interactive nodes corresponds to one question answering stage.

It is to be understood that the nodes may include broadcast nodes, variable setting nodes, or recording nodes, besides the interactive nodes, and this embodiment does not limit this, and generally, a root node in a multi-turn question-and-answer flowchart is an interactive node, and a termination node is a broadcast node.

For ease of understanding, a graphical multi-round question-answering flow chart is shown in FIG. 1 b. As shown in fig. 1b, the diamond-shaped graphic component in the multi-round question-answering flow chart is an interactive node (for example, an age inquiry node 101), and the square-shaped graphic component is a broadcast node (for example, an age not meeting the loan condition node 102). The nodes are connected through node-to-node connecting lines. Wherein, the flow chart of the multi-turn question answering in fig. 1b includes four layers of interactive nodes. Each layer comprises an interactive node, namely: the first layer includes: an inquiry age node 101 (root node) representing an age inquiry stage, a second layer including an inquiry as to whether there is a car-owned house node 103 representing a car-owned house inquiry stage, a third layer including a node 106 inquiring a loan amount representing a loan amount inquiry stage, and a fourth layer including an inquiry installment node 107 representing an installment amount inquiry stage. And different trends of the multi-turn question-answering flow chart are correspondingly determined in each interactive node according to the input different interactive contents. In addition, the multi-turn question-answering flow chart comprises a plurality of termination nodes, namely: the node 102 for indicating the age does not meet the loan condition, the node 109 for indicating excess amount, the node 108 for indicating the excess amount and the node 10A for reporting the loan staging result.

S120, generating a standardized code frame matched with each multi-round question-answering flow chart according to each graphic component included in each multi-round question-answering flow chart, wherein the graphic components comprise: a plurality of interactive nodes.

The multi-turn question-answering flow module capable of being automatically generated is provided. Accordingly, standard implementation code matching different types of graphic components is provided in advance, such as: and establishing standard implementation codes respectively corresponding to the interactive nodes and the broadcast nodes, packaging the standard implementation codes in different library files, and establishing a corresponding relation between the standard implementation codes and the corresponding graphic assemblies in advance. Typically, a storage address (or a reference address) of a standardized implementation code matched with each graphic component may be written in the flow editing interface in advance, and accordingly, a matched standardized code frame may be automatically generated for each graphic component included in a multi-turn question-answering flow chart drawn based on the flow editing interface.

It should be noted that, the embodiment of the present invention mainly focuses on a method for generating a multi-round question-answering system, and therefore, a multi-round question-answering flow chart may include a plurality of interactive nodes, but the technical solution of the embodiment of the present invention may theoretically implement generation of any type of question-answering system, and as long as a corresponding flow chart is drawn as needed, a corresponding standardized code frame may be obtained, and a corresponding flow module may be obtained.

S130, generating custom codes corresponding to the graphic assemblies respectively according to custom configuration information matched with the graphic assemblies in the multi-round question-answering flow chart, and adding the custom codes to positions, associated with the graphic assemblies, in the standardized code frame to generate a multi-round question-answering flow module corresponding to the multi-round question-answering flow chart.

It is understood that the standard implementation code matched to each graphic component includes only general functions that the corresponding graphic component can implement. For example: for an interactive node, the corresponding standard implementation code comprises judgment logic, or for a broadcast node, the corresponding standard implementation code comprises broadcast logic and the like. In order to enable one graphic assembly to realize the functions given to the graphic assembly in the multi-turn question-answering flow chart, corresponding custom configuration parameters need to be input.

As a simple example, for the node 102 whose age does not satisfy the loan condition in fig. 1b, the node 102 whose age does not satisfy the loan condition can broadcast the content "the age does not satisfy the loan condition" after being triggered, and accordingly, the "age does not satisfy the loan condition" is a function assigned to the node 102 whose age does not satisfy the loan condition, and in order to enable the node 102 whose age does not satisfy the loan condition to realize the function, the broadcast content needs to be added to the standardized code frame as custom configuration information.

Typically, blank code segments may be reserved at set positions in standard implementation codes matched with each graphic assembly, and when a custom configuration parameter input for one graphic assembly in the multi-turn question-and-answer flowchart is acquired (for example, through a parameter configuration interface input provided by a flow editing interface), the custom code matched with the custom configuration parameter is added to the corresponding blank code segment, so as to implement a custom graphic assembly function.

Optionally, custom configuration information (for example, age does not satisfy loan conditions) may be directly added to the standardized code frame as the custom code, and a custom code that matches different pre-written custom configuration information may also be added to the standardized code frame according to the custom configuration information (for example, turning on a rejection preference or turning on a knowledge preference), which is not limited in this embodiment.

Correspondingly, if the user-defined setting is completed for all the graphic components included in one multi-turn question-answering flow chart, an implementation code capable of implementing the functions of the multi-turn question-answering flow chart can be generated, namely: a multi-round question-answering flow module according to the embodiment of the invention is generated.

S140, establishing a corresponding relation between each interactive node and one or more knowledge points in a knowledge base, wherein the knowledge points corresponding to the interactive nodes comprise: the system comprises interactive questions and interactive answers, wherein the interactive questions are used for being matched with received user interactive information, and the interactive answers are used for determining the next trend of the multi-turn question-answering flow module.

And the interactive nodes need to determine the next trend of the established multi-turn question-answering flow module according to the user interaction information. Namely: the interactive nodes comprise at least two branches, and different branches correspond to different trends of the multi-turn question-answering flow modules. Therefore, different branch conditions need to be set for different branches in the multi-round question-answering flow module, such as: as shown in fig. 1B, if the query age node 101 determines that the user interaction information is "20 years old full", the multi-turn question and answer flow module goes along the branch a to the node 103 querying whether there is a car room, and if the user interaction information is determined to be "20 years old short", the multi-turn question and answer flow module goes along the branch B to the node 102 not meeting the loan condition.

In fact, the expression form of the user interaction information input by the interactive user (i.e. the user who performs question-answering interaction with the multi-turn question-answering system) under one interactive node may not be unique, or a plurality of different user interaction information may all correspond to the same branch condition. As in the previous example, for example, when the user interaction information is "20 years old full", "grown up", or "meeting the age condition", the multiple rounds of question-answering flow modules all circulate along branch a, and besides setting the dynamic trigger condition of branch a (link) to "20 years old full", it is also necessary to establish an interaction knowledge point matching the interaction node in the knowledge base: (full 20 years old ), (adult, full 20 years old) and (meeting the age criteria, full 20 years old). And respectively establishing the corresponding relation between the interactive knowledge point and the inquiry age node 101. Similarly, for the branch "less than 20 years old", it is also necessary to establish an interaction knowledge point matching the interaction node in the knowledge base: (less than 20 years old ), (immature, less than 20 years old) and (not satisfying the age condition, less than 20 years old). Therefore, the query age node 101 needs to establish correspondence with six interactive knowledge points. It is to be understood that knowledge points corresponding to the interactive nodes are distinguished from question-and-answer knowledge points in the prior art, and therefore, for convenience of distinction, knowledge points corresponding to the interactive nodes will be hereinafter referred to as interactive knowledge points.

The first half part in each bracket represents an interactive question of an interactive knowledge point and is used for matching with received user interactive information, and the second half part in each bracket represents an interactive answer of the interactive knowledge point and is used for determining the next trend of the multi-turn question-answer flow module.

Through the above operations, when the multi-round question-answering flow module flows to the query age node 101, no matter the interactive user inputs "20 years old" or "grown up", the interactive answer "20 years old" is matched in the knowledge base, after the interactive answer "20 years old" is obtained, the multi-round question-answering system can determine that the interactive answer is matched with the dynamic trigger condition set by branch a, and then the multi-round question-answering flow module continues to flow downwards through branch a.

It should be emphasized again that the interaction knowledge points corresponding to the interaction nodes stored in the knowledge base are different from the question-answer knowledge points stored in the knowledge base, as described above, the so-called question-answer knowledge points generally include questions and corresponding answers (also referred to as "question-answer" pairs), where the question-answer knowledge points are mainly used in a scene of asking and answering with the interaction user, the questions in the question-answer knowledge points are used for matching with the user interaction information of the interaction user, and if matching is successful, the answers in the question-answer knowledge points are fed back to the interaction user, or a control program matching with the answer content is invoked.

Namely: the question-answering knowledge points can directly determine the interaction processing result (for example, answer feedback content or execution setting control program calling) corresponding to the user interaction information, and the interaction knowledge points are used for determining the branch conditions of the multi-turn question-answering system and have different purposes. In order to distinguish the two types of knowledge points in different application scenes, the interactive knowledge points and the question-answering knowledge points can be stored in different storage positions in the knowledge base, or knowledge point labels distinguished from the question-answering knowledge points are added in the interactive knowledge points.

In fact, the main purpose of setting the interaction knowledge point is to consider that the content of the received user interaction information may be various for the same interaction node, for example, "20 years old" or "grown up" as described in the previous example, but in order to ensure the simplicity of a multi-turn question-answering system, only a single condition content is generally used when setting a branch condition of the interaction node, for example: "has been 20 years old", and therefore, the concept of interactive knowledge points was introduced. By setting a plurality of interactive knowledge points in the knowledge base for the same branch condition of the same interactive node, namely: and corresponding a plurality of different interactive questions pointing to the same branch to the same interactive answer, namely enabling a plurality of similar expression contents to correspond to the same branch condition.

In other embodiments of the present invention, when the question-answer knowledge point and the interaction knowledge point are different, they may not be distinguished from each other, which is within the protection scope of the present invention.

As described above, a multi-turn question-answering flow module may include a plurality of connectors to connect different nodes, so that the determination of the next trend of the multi-turn question-answering flow module may be implemented by configuring a custom configuration information for connecting an upper layer interactive node and a target connector of a lower layer node.

Accordingly, the custom configuration information may include: dynamic condition configuration information matched with the target connection element; the target connecting piece is used for connecting the associated upper-layer node and the associated lower-layer node, and the associated upper-layer node is an interactive node;

the dynamic condition configuration information is a condition that the multi-turn question-answering flow module flows from the associated upper-layer node to the associated lower-layer node, and the dynamic condition configuration information is matched with an interactive answer in one knowledge point corresponding to the associated upper-layer node in the knowledge base.

S150, adding theme knowledge points corresponding to each multi-turn question-answer flow module in a knowledge base, wherein the theme knowledge points comprise theme questions and theme answers, the theme questions are used for representing triggering conditions of the multi-turn question-answer flow modules, and the theme answers are used for establishing triggering relations between the theme knowledge points and the multi-turn question-answer flow modules.

After a plurality of rounds of question-answering flow modules (codes for realizing a plurality of rounds of question-answering flow charts) are generated and the corresponding relation between an interactive node and one or more knowledge points is established in a knowledge base, in order to realize normal use of the plurality of rounds of question-answering flow modules, theme knowledge points corresponding to each of the plurality of rounds of question-answering flow modules need to be further added in the knowledge base.

It should be noted that the above description provides an implementation manner that first generates multiple rounds of question and answer flow modules and then establishes topic knowledge points, and those skilled in the art can understand that the establishment process of topic knowledge points may not be limited to be performed after generating multiple rounds of question and answer flow modules, and is not limited herein. For example, topic knowledge points may be established first, followed by establishing corresponding rounds of question-answering flow modules, and so on.

In fact, the topic knowledge points are different from the question-answer knowledge points in the knowledge base in that: when the user interaction information input by the interactive user is matched with the questions in the question-answer knowledge points, the answers of the question-answer knowledge points are directly output, or the calling of a control program matched with the answer content is executed, and when the user interaction information input by the interactive user (hereinafter referred to as initial request information) is matched with the subject questions of one subject knowledge point, the multi-turn question-answer flow module is correspondingly triggered (for example, the root nodes of the multi-turn question-answer flow module are directly triggered).

Typically, the topic answers in a topic knowledge point may be storage addresses or calling addresses of multiple rounds of question and answer flow modules corresponding to the topic knowledge point, and the like, which can accurately locate information of the multiple rounds of question and answer flow modules.

The generation method of the multi-turn question-answering system which can be realized through the WYSIWYG mode is provided, the realization mode of the existing multi-turn question-answering system is optimized, the multi-turn question-answering system is quickly constructed and updated, developers are prevented from being introduced into the generation process of the multi-turn question-answering system, the workload of the developers is greatly reduced, the cost is reduced, and the accuracy and the efficiency are improved.

Specifically, the custom configuration information may further include: and rejecting the preference corresponding to the interactive node.

When the multi-turn question-answering flow module flows to a first interaction node configured with a function of starting rejection priority, if the received user interaction information is determined not to be matched with the interaction problem in at least one knowledge point corresponding to the first interaction node in the knowledge base, a rejection response is provided, and the user interaction information is requested to be input again.

Namely: if an interactive node is configured with a rejection preference, only interactive problems based on the interactive node can be identified in the interactive node. Typically, if the rejection preference is set for an interactive node of the multi-turn question-and-answer flowchart, a pre-written custom code matching the rejection preference function is obtained, and the custom code is added to the position associated with the interactive node in the standardized code frame.

By setting the rejection preference, the multi-turn question-answering system can be executed according to a pre-designed flow sequence, and random skipping or feedback caused by some questions which cannot be identified by the multi-turn question-answering system and input by a user can not be carried out, so that the regularity and the sequence of the whole multi-turn question-answering system are better.

Unlike the rejection preference, the custom configuration information may further include: a knowledge preference corresponding to the interactive node;

when the multi-turn question-answering flow module flows to a second interactive node configured with a knowledge priority starting function, if the fact that the received user interactive information is not matched with the interactive problems in at least one knowledge point corresponding to the second interactive node in the knowledge base is determined, the user interactive information is globally searched in the knowledge base, and corresponding interactive operation is executed according to the global searching result.

Namely: if an interactive node is configured with knowledge priority, an interactive problem based on the interactive node is firstly identified in the interactive node, and if the identification fails, problems in other knowledge points are continuously identified in the knowledge base. Typically, if a knowledge preference is set for an interactive node of the multi-turn question-and-answer flowchart, a pre-written custom code matching the knowledge preference function is obtained and added to the standardized code framework at a position associated with the interactive node.

By setting the knowledge priority option, the execution flexibility of the multi-turn question-answering system is ensured, and the question-answering interaction with the user can be well carried out when the fact that the user interaction information is not matched with the currently circulated nodes is determined, so that the user satisfaction is further improved.

In a specific example, for a multi-round interactive system corresponding to the flowchart in fig. 1b, there are 6 interactive knowledge points for the interactive node inquiring about the age node 101, and the interactive questions of the 6 interactive knowledge points are "20 years old reached", "grown up", "meeting the age condition", "not 20 years old", "not grown up", and "not meeting the age condition", respectively, when the input user interaction information does not match with the 6 interactive questions, for example: "what is the weather today", if the query age node 101 sets the rejection preference, the multi-turn question-answering system does not give corresponding feedback for the user interaction information, and stays on the query age node 101 to continue to wait for the user to input new interaction information again; if the query age node 101 sets the knowledge priority, the multi-turn question-answering system searches the knowledge base for the question-answering knowledge point corresponding to the question of the query weather, and feeds back the answer of the question-answering knowledge point.

Specifically, the customized configuration information may further include: backtracking function options corresponding to the interactive nodes;

when the multi-turn question-answer flow module flows to a third interactive node configured with a backtracking starting function, if the received user interaction information is determined to be matched with the interaction problem of the upper node corresponding to the third interactive node in the knowledge base, the multi-turn question-answer flow module flows to the upper node corresponding to the third interactive node.

By setting the backtracking function, the universality of the multi-turn question-answering system is stronger, the trend of the whole multi-turn question-answering system can be readjusted at any time according to the content input by the user in the question-answering interaction process of the multi-turn question-answering system and the user, particularly, the multi-turn question-answering system can be returned to an executed interaction node for re-execution, and the next trend based on the interaction node is re-determined, so that the actual multi-turn question-answering requirement of the user can be better met.

In a specific example, for the multi-round interactive system corresponding to the flowchart of fig. 1B, the user inputs the user interaction information "less than 20 years old" for the query age node 101, and accordingly, the multi-round interactive system flows to the node 102 whose age does not satisfy the loan condition through the branch B and plays the corresponding broadcast content to the user. At this time, if the user re-inputs the user interaction information of "20 years old is full", the multi-turn question-answering system re-flows (backtracks) to the query age node 101, and according to the above content input by the user, the multi-turn question-answering system re-flows to the query whether there is a room in the car node 103 through the branch a to continue the question-answering interaction with the user.

Specifically, the graphic assembly may further include: and broadcasting the nodes. Accordingly, the custom configuration information may include: broadcast content corresponding with the node, the node includes: interaction nodes and broadcast nodes;

and if the multi-turn question and answer flow module flows to a fourth node configured with broadcast contents, correspondingly broadcasting the broadcast contents corresponding to the fourth node.

In a specific example, as shown in fig. 1b, when the multi-turn question and answer system flows to the interactive node 103 inquiring whether there is a car with a room, the interactive node will broadcast a preset broadcast content, for example, "ask you whether there is a car with a room", and then will determine the next trend of the multi-turn question and answer system based on the subsequently received user interaction information; when the multi-turn question-answering system flows to the broadcast node meeting the 20-million loan conditions, the broadcast node can directly broadcast preset broadcast contents, for example: "you satisfy the 20 ten thousand loan conditions".

Through setting the broadcast content, the method can effectively perform question and answer interaction with the user, and can effectively prompt the interactive content which needs to be input by the user in the next step.

Specifically, the customized configuration information may further include: an interrupt function option corresponding to the node;

when the multi-turn question-answering flow module flows to a fifth node with an interruption function, if user interaction information is received before broadcasting of the broadcast content corresponding to the fifth node is finished, continuous broadcasting of the broadcast content is stopped.

The benefits of setting the interrupt function option are: if a user is familiar with the interaction process of the whole multi-turn question-answering system, the user can quickly input information required to interact without waiting for a node in the multi-turn question-answering system to finish broadcasting, and the efficiency of man-machine interaction is further improved.

In a specific example, as shown in fig. 1b, when the multi-turn question and answer system flows to the interactive node 103 inquiring whether there is a car with a house, in the process that the interactive node reports "ask for whether there is a car with a house", if the interactive node receives "there is a car without a house" input by the user, the broadcast content is not continuously reported, but the interactive node quickly flows to the node 104 meeting the 20 ten thousand loan condition to interact with the user, so that the whole question and answer interaction time is saved.

According to various function requirements which can be used by the multi-turn question-answering system, corresponding implementation codes are correspondingly written and packaged, so that a flow designer can conveniently select or input a required custom configuration requirement according to an actual design requirement, and the universality and the use satisfaction of the generation method of the multi-turn question-answering system are further improved.

For easy understanding, a schematic diagram of inputting the custom configuration information of the interactive node is shown in fig. 1 c. As shown in fig. 1c, a schematic diagram of the custom configuration information for the query age node 101 in fig. 1b is given. In the input box corresponding to "knowledge", all the interactive questions corresponding to the query age node 101 may be input.

Fig. 1d shows a schematic diagram of inputting the custom configuration information of the broadcast node. As shown in fig. 1d, a schematic diagram of the custom configuration information for the reminder excess node 109 in fig. 1b is given. In the answer box, the broadcast content corresponding to the excess reminding node 109 may be input.

A schematic diagram of custom configuration information for one input connector is shown in fig. 1 e. As shown in fig. 1d, a schematic diagram of the custom configuration information for the connector corresponding to branch a in fig. 1b is given, wherein in the input box corresponding to "condition", the condition that the branch is selected to execute can be input.

Typically, when a user double-clicks or clicks one graphic component in a multi-turn question-answering flow chart, the input template of the user-defined configuration information is correspondingly popped up, and a flow designer can input different user-defined configuration information to different graphic components through simple selection and input operation.
