Please refer to fig. 1, which is a flowchart illustrating a session management method according to a first embodiment of the present invention. A dialogue management method of a first embodiment of the present invention includes the steps of:
s10: drawing a taskflow flow chart according to the dialogue logic, and storing the taskflow flow chart in a database;
in this step, the taskflow flowchart is the pre-drawn dialog logic. In the embodiment of the present application, in order to improve the drawing efficiency, five nodes for implementing different functions are designed, which are respectively: API interface node, SLOTS fill out the groove node, SCRIPT SCRIPT node, NLG reply node, JUDGE JUDGE five nodes to constitute, the function of each node is as follows:
API interface node: the method is used for acquiring the service information through remote calling in the conversation process. An API interface node may be created by configuring a URL (Uniform Resource Locator), an interface entry (key-value format) and an exit of a remote service. In the embodiment of the invention, when the taskflow flow chart is drawn, the API interface node shields the detail information of remote calling through the API gateway service, the difference of different remote calling parties does not need to be noticed, and the user experience and the editing efficiency of the conversation flow are greatly improved.
SLOTS slot filling node: the method is used for collecting slot position information (namely key information needing to be collected to a user) in the execution conversation process, and slot filling is carried out through NLU enabling. In the process of executing the conversation process, the slot filling node continuously traverses all slot positions, when finding an unfilled slot position, the slot position corresponding To a clarified Speech technology is output To TTS (Text To Speech from Text To Speech), a user inputs information under the guidance of the TTS Speech, and after extracting the user intention according To the user input information through an NLU entity, the unfilled slot position is filled through the slot filling node.
SCRIPT node SCRIPT: the method is used for acquiring the conversation state information through the embedded groovy script in the conversation process execution process, controlling and modifying the conversation state information and realizing the customization requirement of the conversation process. Namely, the general dialog management engine execution logic is developed by using a static Java language and edited by a TaskFlow, and the groovy SCRIPT embedded in the SCRIPT SCRIPT node is processed by processing the specific field service logic, so that the system operation and the service field are decoupled. Specifically, the groovy script may acquire the dialog state information through a session.get ('key') statement, and after processing, set the updated dialog state information through a session.set ('key', value) statement. Taking the identification of the gender status information of the user as an example:
def g＝session.get('gender')
set ('gender', g ═ 0
NLG replying node: the method is used for giving dynamically changed data in a templatized mode in the process of executing the conversation process to generate the reply conversation. The sentence template comprises a plurality of short sentences containing variables, the variables are dynamically kept updated by data information and are generated by related business rules, and finally the short sentences are spliced into a complete sentence with a good structure.
Judge JUDGE node: the method is used for controlling the trend of the conversation process according to the configured conditional expression during the execution process of the conversation process. The JUDGE judging node supports and configures a plurality of conditional expressions with priorities, variables supported by the conditional expressions are provided by current conversation state information, when the node runs, the conditional expressions are executed according to the priorities, and if the value of the conditional expression is true, the trend of the conversation process is controlled to jump to the branch and the conversation process is continuously executed.

Meanwhile, judging whether the current node needs to wait for the reply of the user, and if not, returning execution state information; if necessary, a state information object input by the user is created, and the slot position of the state information object is filled after the user input is recognized. And after the input is finished, pressing the next triggered node in the TaskFlow flow chart into the task stack, executing the process on the node again, and clearing the executed node in the stack. And circularly executing the processes until the conversation task is completed.

s22: the dialog management module loads the taskflow flow chart according to the user intention, and analyzes the taskflow flow chart by adopting a Jackson tool to acquire a dialog flow;
in this step, the taskflow flowchart is the pre-drawn dialog logic. In the embodiment of the present application, in order to improve the drawing efficiency, five nodes for implementing different functions are designed, which are respectively: API interface node, SLOTS fill out the groove node, SCRIPT SCRIPT node, NLG reply node, JUDGE JUDGE five nodes to constitute, the function of each node is as follows:
