Node.js 节点自然语言处理中的实体提取

我正在使用node nlp创建一个聊天机器人，用于帮助用户预订套餐/旅行，我想从话语中提取目的地名称、开始日期、结束日期、成人和儿童。目前，我正在使用以下方法：

   nlp_manager.addDocument('en', 'planning %destination_name% from %start_date% till %end_date% with %adult% parents and %child% kids','book_package');
   nlp_manager.addDocument('en', 'visiting %destination_name% from %start_date% to %end_date% with %adult% adult and %child% childs','book_package');

对于拉动实体，我使用修剪命名实体：

   const destination_name = manager.addTrimEntity('destination_name','trim');
   destination_name.addBetweenCondition('en', 'visit', 'with');
   destination_name.addBetweenCondition('en', 'visit', 'from');
   destination_name.addBetweenCondition('en', 'going to', 'from');
   destination_name.addBetweenCondition('en', 'going to', 'with');
   destination_name.addBetweenCondition('en', 'packages to', 'with');
   destination_name.addBetweenCondition('en', 'package to', 'with');
   destination_name.addBetweenCondition('en', 'package to', 'from');

   const adult = manager.addTrimEntity('adult','trim');
   adult.addBetweenCondition('en','with','adults and');
   adult.addBetweenCondition('en','and','adults');

   const child = manager.addTrimEntity('child','trim');
   child.addBetweenCondition('en','and','childs');
   child.addBetweenCondition('en','with','childs and');

   const start_date = manager.addTrimEntity('start_date','trim');
   start_date.addBetweenCondition('en','from','to');
   start_date.addBetweenCondition('en','from','till');

   const end_date = manager.addTrimEntity('end_date','trim');
   end_date.addBetweenCondition('en','to','with');
   end_date.addBetweenCondition('en','till','with');

在训练模型并向机器人发出声音后，NER经理无法从声音中提取实体。话语的一个例子：

   i am planning to visit europe from 21 june to 25 june with 2 adults and 3 childs

你能建议一个更好的方法吗。
