$P (t) = P_{L} (t) = l_{t} / l_{c}$	location based probability of $t \in T$
$P (d) = P_{L} (d) = l_{d} / l_{c}$	location based probability of $d \in D$
$P_{D} (t) = \| D_{t} \| / \| D \|$	document based probability of $t \in T$
$P_{T} (d) = \| T_{d} \| / \| T \|$	term based probability of $d \in D$
