Hi , I 'm looking for a 4-star hotel with free wifi .
request((_:search,area,?);(_:search,type,'Hotel')) inform((_:result,area,'east');(_:result,area,'north');(_:result,category,'guesthouses');(_:result,count,'2');(_:result,type,'Hotel'))
system
Sure thing . I have two options for you , and they are both guesthouses . One in the east , and one in the north . Do you have a preference ?
inform((_:search,pricerange,'cheap');(_:search,type,'Hotel'))
user
Are either of those two cheap ?
offer((_:booking,type,'Booking')) inform((_:result,pricerange,'moderate');(_:result,type,'Hotel'))
system
No I am sorry , they are both in the moderate price range .   Would you like to book one of them ?
inform((_:search,has_internet,'yes');(_:search,pricerange,'cheap');(_:search,stars,'4-star');(_:search,type,'Hotel'))
user
Any one will do as long as it has a 4-star rating with free wifi and is cheap .
request((_:search,pricerange,?);(_:search,stars,?);(_:search,type,'Hotel')) canthelp((_:search,pricerange,'cheap');(_:search,stars,'4-star');(_:search,type,'Hotel')) select((_:result,pricerange,'higher price range');(_:result,stars,'not as fancy');(_:result,type,'Hotel'))
system
There are no 4-star places that are cheap and have free wifi . Perhaps something not as fancy , or in a higher price range ?
user
I 'm not sure .   I really needed those specifications .
offer((_:booking,type,'Booking')) inform((_:result,amount,'several');(_:result,area,'north');(_:result,category,'guesthouse');(_:result,has_internet,'none');(_:result,name,'The alexander bed and breakfast');(_:result,pricerange,'cheap');(_:result,stars,'four');(_:result,type,'Hotel'))
system
I apologize , we have several options . The alexander bed and breakfast is a cheap four star guesthouse , in the north area , with wifi . Would you care to reserve a room ?
inform((_:search,day,'wednesday');(_:search,people,'5');(_:search,stay,'3');(_:search,type,'Hotel'))
user
Yes , let 's book it for 3 nights from Wednesday . There will be 5 of us .
