47. Since September 14th, which customers called the person X?
The person with phone number +86 921 547 9004 has been identified as a lead. We (company
"Telecom") would like to know which of our customers have been in contact with this person
since September 14th. This will help us in converting this lead into a customer.
match
$customer isa person has phone-number $phone-number;
$company isa company has name "Telecom";
(customer: $customer, provider: $company) isa contract;
$target isa person has phone-number "+86 921 547 9004";
(caller: $customer, callee: $target) isa call has started-at
$started-at;

get $phone-number;

48. Who are the people who have received a call from a London customer aged over 50 who
has previously called someone aged under 20?
We (company "Telecom") have received a number of harassment reports, which we suspect is caused by one individual. The only
thing we know about the harasser is that he/she is aged roughly over 50 and lives in London. The reports have been made by
young adults all aged under 20. We wonder if there is a pattern and so would like to speak to anyone who has received a call from
a suspect, since he/she potentially started harassing.
match
$suspect isa person has city "London", has age > 50;
$company isa company has name "Telecom";
(customer: $suspect, provider: $company) isa contract;
$pattern-callee isa person has age < 20;
(caller: $suspect, callee: $pattern-callee) isa call has started-at $pattern-call-date;
$target isa person has phone-number $phone-number, has is-customer false;
(caller: $suspect, callee: $target) isa call has started-at $target-call-date;
$target-call-date > $pattern-call-date;
get $phone-number;

49. Who are the common contacts of customers X and Y?
The customer with phone number +7 171 898 0853 and +370 351 224 5176 have been
identified as friends. We (company "Telecom") like to know who their common contacts are in
order to offer them a group promotion.
match
$common-contact isa person has phone-number $phone-number;
$customer-a isa person has phone-number "+7 171 898 0853";
$customer-b isa person has phone-number "+370 351 224 5176";
(caller: $customer-a, callee: $common-contact) isa call;
(caller: $customer-b, callee: $common-contact) isa call;
get $phone-number;

50. How does the average call duration among customers aged under 20
compare with those aged over 40?
In order to better understand our customers' behaviour, we (company "Telecom") like to know how the average
phone call duration among those aged under 20 compares to those aged over 40.
match
$customer isa telecom-customer has age < 20;
$company isa company has name "Telecom";
(customer: $customer, provider: $company) isa contract;
(caller: $customer, callee: $anyone) isa call has duration
$duration;
aggregate mean $duration;

51. Who are the customers who 1) have all called each other and
2) have all called person X at least once?
The person with phone number +48 894 777 5173 has been identified as a lead. We (company "Telecom")
would like to know who his circle of (customer) contacts are, so that we can encourage them in converting this
lead to a customer.
match
$target isa person has phone-number "+48 894 777 5173";
$company isa company has name "Telecom";
$customer-a isa person has phone-number $phone-number-a;
$customer-b isa person has phone-number $phone-number-b;
(customer: $customer-a, provider: $company) isa contract;
(customer: $customer-b, provider: $company) isa contract;
(caller: $customer-a, callee: $customer-b) isa call;
(caller: $customer-a, callee: $target) isa call;
(caller: $customer-b, callee: $target) isa call;
get $phone-number-a, $phone-number-b;
