It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in other sequences than those illustrated or described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

It should be noted that, the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for presentation, analyzed data, etc.) referred to in the present disclosure are information and data authorized by the user or sufficiently authorized by each party.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating an application environment according to an exemplary embodiment, which may include a terminal 100, a server 200, and a terminal 300, as shown in fig. 1.

The terminal 100 may be used to provide multiple rounds of dialog development services to any one user. Specifically, the terminal 100 may include, but is not limited to, a smart phone, a desktop computer, a tablet computer, a notebook computer, a smart speaker, a digital assistant, an Augmented Reality (AR)/Virtual Reality (VR) device, a smart wearable device, and other types of electronic devices, and may also be software running on the electronic devices, such as an application program. Optionally, the operating system running on the electronic device may include, but is not limited to, an android system, an IOS system, linux, windows, and the like.

In an optional embodiment, the server 200 may provide a background service for the terminal 100, receive the page configuration data of the session node sent by the terminal 100, and convert to generate corresponding operation trigger information, such as a rule object corresponding to the session node. Optionally, a rules engine is installed in the server 200. Alternatively, the rules engine may be any rules engine including, but not limited to, easy-rules engines, drool rules engines.

In the rules engine, one or more sets of objects with conditions and operations may be created and stored in a collection and then run, and upon satisfaction of the conditions, the operations may be executed. Each simple rule object (rule) has a condition and a number of operations. A compound rule object can be a variety of combinations of simple rule objects, a compound rule is also a rule whose conditions and actions consist of simple rules, such as: and after the conditions of all the simple rules are met, executing the operations of all the simple rules, or meeting the condition of one of the simple rules, and only executing the operation of the simple rule.

Specifically, the server 200 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a Network service, cloud communication, a middleware service, a domain name service, a security service, a CDN (Content Delivery Network), a big data and artificial intelligence platform, and the like.

In an alternative embodiment, the terminal 300 may send a dialog message to the server 200, and the server 200 generates a reply message corresponding to the dialog message based on the rule engine and the converted operation trigger information, and sends the reply message to the terminal 300, thereby implementing the automatic dialog process.

In one example, as shown in fig. 2, a flow diagram illustrating a single round of session processing by a server is shown. A single round of dialogue consists of several trigger conditions, slots, outputs and node flows. The whole Dialog process can be abstractly summarized as user utterance input, NLU (Natural Language Understanding) processes the user input, DM (Dialog Management) judges whether a trigger condition is satisfied, if a trigger condition is satisfied, a series of operations (such as a slot filling operation) triggered based on the trigger condition are performed, and finally a result is output. The DM is used for conversation management of a multi-turn conversation system, controls the process of man-machine conversation, records conversation states and historical information, analyzes user requirements, and achieves the purpose of a user through calculation and decision.

The multi-turn dialog is that the current state and the context information are recorded additionally on the basis of a single turn of dialog, and the structure of the single turn of dialog just meets the condition of using a rule engine. In one example, as shown in FIG. 3, a multi-turn dialog technology architecture diagram based on a rules engine implementation is illustrated. Alternatively, the multi-turn dialog engine 30 in fig. 3 is installed in the server 200, the client 31 is installed in the terminal 300, and the service configuration data may be configured in the terminal 100 by a developer. In the technical architecture shown in fig. 3, the multi-turn dialog engine uses a rule engine (rule engine) including an easy-rules component as a kernel, and the kernel and the page configuration structure of the multi-turn dialog engine are independent and do not affect each other. The input stream translates the configuration data of the page configured session node into the corresponding rule. The user via the client 31 may send a request stream to the server 200, which includes the dialog messages sent by the user. The multi-turn dialog engine processes according to the converted rule to generate a reply message, and sends the reply message to the client 31 through the output stream.

In addition, it should be noted that fig. 1 shows only one application environment provided by the present disclosure, and in practical applications, other application environments may also be included, for example, more terminals may be included.

In the embodiment of the present specification, the terminal 100, the server 200, and the terminal 300 may be directly or indirectly connected through wired or wireless communication, and the disclosure is not limited herein.

Fig. 4 is a flowchart illustrating a dialog processing method according to an example embodiment. Optionally, the dialogue processing method is applied to an electronic device. Optionally, the electronic device is a server. As shown in fig. 4, the method may include the following steps (410-440).

And step 410, receiving the dialogue message sent by the terminal.

Optionally, the dialog message is a dialog message input by a user at the terminal. Optionally, a client corresponding to the target application is installed in the terminal. The client may include a chat system, such as a customer service system.

Optionally, the dialog message is a dialog message corresponding to the first user account.

Step 420, obtaining operation trigger information corresponding to at least one session node.

Optionally, the operation trigger information corresponding to each session node in the at least one session node is generated based on the page configuration data conversion corresponding to each session node. Optionally, the operation trigger information corresponding to each session node includes a trigger condition corresponding to each session node and an operation corresponding to the trigger condition.

Optionally, the page configuration data is generated based on a configuration operation performed by the target object in the front-end configuration page of the session node. The front-end configuration page may be a webpage displayed by the terminal, where the terminal is a configuration terminal. Based on the front-end configuration page, selection operation and configuration operation aiming at the at least one dialogue node can be received, and the configuration terminal responds to the selection operation and the configuration operation to generate page configuration data corresponding to the at least one dialogue node.

Optionally, the user may also select a related option in the front-end configuration page and input related information, after receiving the target selection option and the input configuration information, the configuration terminal may send the target selection option and the input configuration information to the server, and the server may refine the page configuration data corresponding to the at least one session node according to the target selection option and the input configuration information. The embodiment of the present disclosure does not limit the generation manner of the page configuration data.

Optionally, the front-end configuration page may be a front-end configuration page in different configuration modes, for example, a graph-structured dialog configuration page and a tree-structured dialog configuration page, where front-end configuration logics corresponding to different structures are different. Accordingly, the at least one dialog node corresponds to at least one form of dialog structure, including but not limited to graphical dialog structures and tree dialog structures.

Optionally, the operation trigger information is combination information of a trigger condition and an operation corresponding to the dialog node, and may specifically be a data structure object including the trigger condition and the operation. Optionally, the operation trigger information includes a rule object. The rule object is a data object that can be processed by a rule engine deployed in a server, and may include a trigger condition corresponding to the dialog condition and at least one operation corresponding to the trigger condition.

Alternatively, the rule objects are divided into simple rule objects and complex rule objects. Each simple rule object corresponds to a condition and at least one operation corresponding to the condition. A composite rule object may be a combination of rule objects formed from at least two simple rule objects.

Optionally, the rule object is operation trigger information corresponding to the session node. The correspondence between the session nodes and the rule objects is flexible and changeable, one session node may correspond to one simple rule object or one composite rule object, and a plurality of session nodes may correspond to a common composite rule object, which is not limited in the embodiments of the present disclosure.

Page configuration data corresponding to a dialog node in different dialog structures and conversion modes thereof may be different, and a process of converting the page configuration data into operation trigger information under the two dialog structures will be described below by taking a graphic dialog structure and a tree-shaped dialog structure as examples.

In a possible embodiment, the at least one dialogue node is a dialogue node in a graph dialogue structure; accordingly, as shown in fig. 5, the process of acquiring the operation trigger information corresponding to the at least one session node includes the following steps (421 to 423), and fig. 5 is a flowchart of a session processing method according to an exemplary embodiment.

In step 421, page configuration data corresponding to at least one session node is received.

The generation process of the page configuration data has been described in the foregoing, and is not described herein again, and an example is listed below to facilitate understanding by those skilled in the art.

In one example, as shown in FIG. 6, a diagram of a dialog configuration page of a graphical dialog structure is illustrated. The graphic dialog structure configuration page 60 shown in fig. 6 includes a dialog configuration region 61 and a node configuration region 62. A dialog node selection menu 611 may be displayed in the dialog configuration region 61, in which various preset types of dialog nodes are displayed, and specifically, the dialog nodes may include a dialog input node, a judgment node, a service call node, a function node, an assignment node, a reply node, and a slot filling node. The user can select a dialog node of a desired configuration through the node selection menu 611 and drag it into the dialog configuration region 61 for connection configuration. As shown in fig. 6, a configured graph dialog structure 612, specifically a dialog node structure corresponding to the leave-asking dialog process is shown, which includes a leave-asking trigger node, a leave-asking information collection node, and a leave-asking application submission node. The leave-asking triggering node is an input node, the leave-asking information collecting node is a slot filling node, and the leave-asking application submitting node is a reply node. The user may configure the selected session node through the node configuration area 62, for example, after the user selects the leave application submission node, the user may configure the trigger condition and operation of the leave application submission node through the node configuration area 62, so as to generate the page configuration data of the leave application submission node.

At step 422, at least one conversation node is traversed.

For each dialog node in the graph dialog structure, the device may generate operation trigger information for each dialog node, for example, construct a rule object, and therefore, it is necessary to traverse the at least one dialog node, determine a trigger condition and an operation corresponding to each dialog node, and generate corresponding operation trigger information, for example, a rule object. Alternatively, the last operation of each rule object may be to notify the rule engine in the server to execute the next rule.

Step 423, performing conversion processing on the page configuration data corresponding to the traversed session node to obtain operation trigger information corresponding to the traversed session node.

By traversing each session node in the at least one session node and converting the page configuration data corresponding to each traversed session node, the operation trigger information corresponding to each session node can be obtained, and the uniform conversion of the page configuration data at the back end is realized, so that the back-end server can realize session processing according to the operation trigger information after the uniform conversion, the coupling degree between the front-end configuration and the back-end processing in a session processing architecture is effectively reduced, and the expandability of a back-end session processing engine is improved.

Optionally, at least one type of session node corresponds to the graphic session structure, including but not limited to a session input node, a judgment node, a default execution node and a slot filling node. Optionally, the default execution node refers to a session node that can be directly executed without determining a trigger condition or having no trigger condition.

Each slot position has corresponding slot filling condition configuration data, and the slot filling condition configuration data is trigger condition data configured for the corresponding slot position by a target object, for example, the slot position data is empty, and for example, the slot position data is overdue. Optionally, the operation configuration data is data configured by the target object for the corresponding slot to perform the corresponding slot filling operation, for example, the corresponding operation at a certain slot is an operation to fill the slot data. The embodiment of the present application does not limit the setting of the slot positions, and the form and content of the slot filling condition configuration data and the operation configuration data corresponding to each slot position. When the conversion is performed, the slot filling condition configuration data corresponding to each slot position can be converted into the trigger condition in the rule object corresponding to each slot position, the operation configuration data corresponding to each slot position is converted into the operation in the rule object corresponding to each slot position, the trigger condition and the operation corresponding to each slot position are combined to generate the simple rule object corresponding to each slot position, and the simple rule objects corresponding to each slot position are combined to generate the composite rule object corresponding to the slot filling node (i.e. the operation trigger information corresponding to the slot filling node), so that the conversion of the page configuration data corresponding to the slot filling node is realized.

Therefore, after determining the target session node corresponding to the session message in the tree-shaped session structure, at least one preset operation corresponding to the target session node may be executed, that is, a reply message corresponding to the session message may be generated, and the target session node may be recorded, and after a next session message is sent, a trigger condition corresponding to a next session message may be searched from operation trigger information corresponding to a sub-session node corresponding to a last hit session node, and then the target session node is determined again, and at least one preset operation corresponding to the re-determined target session node is executed, so that a new reply message is generated until no new session message is received.

In another possible embodiment, at least one of the conversation nodes is a conversation node in a tree-like conversation structure; accordingly, as shown in fig. 7, the implementation of step 430 may include the following steps (43 a to 43 b).

In step 43a, in case the dialog message satisfies the target trigger condition, the target dialog node is determined as the execution dialog node, and the target trigger condition is determined as the execution trigger condition.
