Given a phrase pair (f j 2 j 1 , e i 2 i 1 ), we denote the inside area as in(j 1 , j 2 , i 1 , i 2 ) and the outside area as out(j 1 , j 2 , i 1 , i 2 ).
the inside probability of a phrase pair is calculated as China 's 1.0 0.24 0.24 China 1.0 0.24 0.24 's economy 0.4 0 0 Table 1: Some candidate target phrases of the source phrase "zhongguo de" in Figure 4, where α is inside probability, β is outside probability, and count is fractional count.
