Bagaimana pemetaan dari strukture kalimat (syntactic aspect) ke makna kalimat (semantic aspect)?

Sintatik aspek adalah berusaha memahami sebuah kalimat menjadi frase frase kecil seperti 
He was cooking when his parents called him 
dua frase
He was cooking
his parents called him 

Nah kemudian ke semantik yang artinya berusaha memahami perilaku manusia berdasarkan diksi seperti sinonim, antonim, dsb

sinonim dari cooking 
He was boiling 
His parents look for him (look for past tense : mencari)

He was boiling when his parents look for him
