Hello , I am looking for a train departing from Cambridge , and leaving on Friday . Do you see anything for that time ?
inform((_:result,amount,'tons of them');(_:result,type,'Train')) request((_:search,destination,?);(_:search,type,'Train'))
system
There are tons of them ! Can you tell me a bit more about your trip so we can narrow it down a little ? Where would you like to go ?
inform((_:search,destination,'london liverpool street');(_:search,leave_at,'13:30');(_:search,type,'Train'))
user
Yes I want to leave after 13:30 and arrive at London Liverpool Street .
inform((_:result,arrive_by,'15:27');(_:result,count,'6');(_:result,leave_at,'13:59');(_:result,type,'Train'))
system
There are 6 options available . Would leaving at 13:59 and arriving at 15:27 work for you ?
request((_:result,id,?);(_:result,type,'Train'))
user
Yes , that would be perfect .   Can you just give me the train ID for that ?
inform((_:result,id,'TR4187');(_:result,type,'Train')) reqmore()
system
That is train TR4187 .   Is there anything else I can help with ?
inform((_:search,area,'centre');(_:search,category,'multiple sports');(_:search,type,'Attraction'))
user
Yes are there any multiple sports places to go in the centre ?
canthelp((_:search,area,'center');(_:search,category,'sports');(_:search,type,'Attraction')) request((_:search,category,?);(_:search,type,'Attraction'))
system
There are no sports in the center . Shall I change type or location for you ?
inform((_:search,category,'theatre');(_:search,type,'Attraction'))
user
Hmm , that kind of stinks . Well , how about a theatre instead ?
reqmore() inform((_:result,area,'centre');(_:result,category,'theaters');(_:result,count,'4');(_:result,name,'mumford');(_:result,type,'Attraction'))
system
I have 4 theaters in the centre area . The mumford is one of my favorites . Can I give you more information on one ?
request((_:result,entrance_fee,?);(_:result,type,'Attraction'))
user
What 's the entrance fee ?
reqmore() inform((_:result,entrance_fee,'I');(_:result,entrance_fee,'unaware of what their entrance fee is');(_:result,type,'Attraction'))
system
I am unaware of what their entrance fee is at this time . Sometimes that happens because prices fluctuate and I apologize .   Can I help with anything else ?
thank()
user
No thank you , goodbye .

You 're welcome , have a nice day .
