nlp - 以相同的意图进行 Rasa 多次查找

我一直在尝试使用 Rasa NLU 作为酒店预订聊天机器人。我正在尝试提取两个特征，房间类型和房间数量。这是我的 nlu.md 文件

## intent:bot_challenge
- are you a bot?

当我输入“预订 2 间豪华客房”时，机器人问我需要多少间客房。意图被错误地分类。我尝试了这个答案RASA NLU: Multiple entity extract from Single intent，但这并没有取得成果。请帮忙。

请注意regex和lookup被转换为特征。仅仅因为您在查找表中列出“DELUX”并不意味着您的助手总是将其提取为room_type. 另请参阅 Rasa 的文档。

我猜你的助手主要是不工作，因为你的NLU数据需要更新：（1）你需要用适当的值替换[num_rooms]和。[room_type_name]Rasa 不会自行替换[num_rooms]为数字。意图下列出的例子应该是正常的句子。(2)book_room_all_details应标记为意图，否则您的助手不知道该意图。

这里更新的 NLU 数据：

## intent:book_room
- i would like to book a room
- i want a room
- i want to book room
- i would like a room
- i want to have a room
- i want to book
- i would like to book


## intent:book_n_rooms
-  [4](num_rooms) rooms
-  I would like to book [1](num_rooms)
-  I want [2](num_rooms) rooms
-  I need [3](num_rooms) rooms
-  I want to have [2](num_rooms) rooms

## intent:room_type
-  I would like a [deluxe](room_type_name) room
-  Well, I want [simple](room_type_name)
-  I need [Simple](room_type_name) rooms
-  I prefer [DELUXE](room_type_name) rooms

## intent:book_room_all_details
-  I would like to book [2](num_rooms) [deluxe](room_type_name) rooms
-  I would like to book [3](num_rooms) [deluxe](room_type_name) type rooms
-  I want [1](num_rooms) [Simple](room_type_name) room
-  I want [1](num_rooms) [simple](room_type_name) type room
-  I want [2](num_rooms) [SIMPLE](room_type_name) rooms
-  book [3](num_rooms) [simple](room_type_name) type rooms

-  I want [5](num_rooms) rooms [DELUXE](room_type_name)
