NUMB:: sing | plur. PERS:: first | secnd | third. TRAN:: intrans | trans. RULE sentence: subject(NUMB, PERS), verb part (intrans, NUMB, PERS) / "[", subject, ",", verb part, "]";The transitivity feature of the verb determines whether it takes an object. Assuming a suitable transduction for subject and verb part, this rule would transduce I am freezing to [I, freeze].
RULE sentence: subject(NUMB, PERS), verb part (trans,NUMB,PERS), object / "[",subject,",[",verb part,",",object,"]]".Under similar assumptions, this should transduce I was attending a software engineering conference to [ I, [attend, [conference, software engineering]]].
