1. fallback
机器人不明白用户意思的时候，兜底的操作，答出 “对不起，xxx” 的友好提示
NLU fallback
pipeline:
- name: FallbackClassifier
threshold: 0.6
ambiguity_threshold: 0.1配置的意思：意图分类组件预测的结果中，最高的置信度 <= 0.6 or 最高的前2个意图得分之差 <= 0.1 ，那么 NLU 的意图 就会被替换为 nlu_fallback
比如，
rules:
- rule: 要求用户重说
steps:
- intent: nlu_fallback
- action: utter_please_rephrase如果预测的下一个动作 置信度不高，或者有两个很相近的，也可以配置策略
policies:
- name: RulePolicy
core_fallback_threshold: 0.3
core_fallback_action_name: "action_dafault_fallback" # 很模糊时，配置执行该动作
enable_fallback_prediction: True2. 意图触发动作
- 自定义意图触发动作
rules:
- rule: 意图 -> 动作映射
steps:
- intent: some_intent
- action: some_action在 policy 字段值为 RulePolicy 时，用户表达 意图后，100% 触发 配置的动作
3. 表单
理解用户意图后，引导用户填表，完毕后执行动作
需要规则策略
policies:
- name: RulePolicy定义表单
forms:
weather_form:
required_slots: # 表单必须指定该字段
- address
- date-time激活表单
设定什么时候进入该表单， rule 指定
rules:
- rule: 激活 rule
steps:
- intent: weather # 出现该意图
- action: weather_form # 执行该动作
- active_loop: weather_form # 进入表单填词槽-询问过程执行表单任务
满足表单条件后，词槽全部填好，执行任务
- rule: 提交 form
condition:
- active_loop: weather_form
steps:
- action: weather_form
- active_loop: null
- slot_was_set:
- requested_slot: null # 所有词槽填完
- action: action_weather_form_submit # 执行动作4. 天气预报机器人
