''' - This ChatTree simulates medical treatment registration. The user communicates with the hospital registration robot to provide relevant medical treatment information (such as visiting department, visit date, visit time, etc.) - The core of the ChatTree is the "#multi_turn_interact#" node, especially the check_registered_info() function pointed to by the "execution function" attribute: This function will be executed during each round of dialogue, verify the information provided by the user, and give corresponding prompts (through the {_multi_turn_interact_dynamic_prompt_} system InfoItem) to guide the user to provide correct or more specific information until the registration conditions are met or a system exception occurs and the user needs to exit. - This kind of business logic implemented with the "#multi_turn_interact#" node as the core is only suitable for situations where there are relatively few infoitems that need to be collected (for example, there are only 3 in this ChatTree). If there are more infoitem that need to be collected, or the logical relationship between the infoitem is more complex, you need to use several "#single_turn_interact#" nodes to implement it. For details, see "TMC.py" / "TMC_book_flight.py" ChatTree - At the same time, during the entire process, the system can provide relevant knowledge of the "first aid knowledge, hospital treatment and registration guide" knowledge base at any time based on the user's input without interrupting the logic of the dialogue process. - Finally, you can execute "python ./ichatdef/firstapp/py_chattree/hospital_registration.py" in the server's project directory to generate "hospital_registration.html", download it locally and open it with a browser, you can see the topology structure of the entire ChatTree and related code information ''' # ------------------------------------------------------------------------------------- # Standard code header for every python ChatTree file # ------------------------------------------------------------------------------------- import sys, os project_root = os.path.abspath(os.path.join(os.path.dirname(os.path.abspath(__file__)), "../../..")) if project_root not in sys.path: sys.path.append(project_root) from chattree_def import * chattree = ChatTree() # ------------------------------------------------------------------------------------- # The definition part of the CHatTree node # ------------------------------------------------------------------------------------- from datetime import datetime, timedelta import random, re department_list = [ 'Cardiovascular Medicine', 'Respiratory Medicine', 'Gastroenterology', 'Neurology', 'Endocrinology', 'General Surgery', 'Orthopedics', 'Urology', 'Gynecology', 'Obstetrics', 'Pediatrics', 'Ophthalmology', 'ENT', 'Stomatology', 'Dermatology', ] # start node start_node = chattree.create_node( "#start#", { "chattree_title":"Hospital registration service", # A short text describing the topic or purpose of this ChatTree "system_role":"hospital registration robot", "user_role":"patient", "background_information":"You are responsible for registering patients for medical treatment and answering related questions", "allow_transfer_human_agent":False, "static_reference_information":"first_aid_and_hospital_consultation_and_registration_guide", # Point to the knowledge base file name (without extension) }) # Before entering the following multi_turn_interact nodes, give the user a welcome prompt. def execute_srcipt(ctx): ctx["{_multi_turn_interact_dynamic_prompt_}"] = "Ask the patient: 'Hello, which department and what time would you like to register for?'" execute_srcipt_node = chattree.create_node( "#activity#execute_script#", { "function":execute_srcipt, }) # The core nodes and related functions of this CHatTree def register(register_department, register_date, register_time): # Simulated registration function (returns relevant results based on probability).
