Algorithm 1: Algorithm for Scenario Generation

Input: location ${\mathrm{l}}_{\mathrm{j}}$, person in social group ${\mathrm{p}}_{\mathrm{j}}$, user activity ${\mathrm{ac}}_{\mathrm{j}}$, ${\mathrm{Scenario}}_{\mathrm{new}}$, ${\mathrm{Scenario}}_{\mathrm{similar}}$

Output: Scenario ${\mathrm{sc}}_{\mathrm{j}}$

1: if ${\mathrm{ac}}_{\mathrm{j}}\notin \mathrm{ACset}$ then

2:  ${\mathrm{sc}}_{\mathrm{j}}$ = ${\mathrm{Scenario}}_{\mathrm{new}}$

3: else if ${\mathrm{l}}_{\mathrm{j}}\notin {\mathrm{L}\mathrm{or}\mathrm{p}}_{\mathrm{j}}\notin \mathrm{SG}$ then

4:  ${\mathrm{sc}}_{\mathrm{j}}$ = ${\mathrm{Scenario}}_{\mathrm{new}}$

5: else

6:  ${\mathrm{sc}}_{\mathrm{j}}$ = ${\mathrm{Scenario}}_{\mathrm{similar}}$

7: end if
