f (e, C(v)) = 1, if e = ♣ and C(v).♥ = ♠ 0, else (3) where the symbol ♣ is a placeholder for a possible target translation (up to 4 words), the symbol ♥ indicates a contextual (lexical or semantic) element for the verbal predicate v, and the symbol ♠ represents the value of ♥.
lexical Features: The lexical element ♥ is extracted from the surrounding words of verbal predicate v. We use the preceding 3 words and the succeeding 3 words to define the lexical context for the verbal predicate Semantic Features: The semantic element ♥ is extracted from the surrounding arguments of verbal predicate v. we define a semantic window centered at the verbal predicate with 6 arguments are arguments on the left side of v while A 1 − A 3 are those on the right side.
