A category ( s \ np ) / pp might describe an intransitive verb with a prepositional phrase complement ; it combines on the right ( / ) with a constituent with category pp , and then on the left ( \ ) with a noun phrase ( np ) that serves as its subject . We follow Lewis and Steedman ( 2014 ) in allowing a small set of generic , linguistically-plausible unary and binary grammar rules . We further add rules for combining with punctuation to the left and right and allow for the merge rule X â X X of Clark and Curran ( 2007 ) .
