This page contains some notes on the lexical types used in Jacy.

There is also an on-line database.

Postpositions connect two objects in the grammar.

Case postpositions (such as が, を, に) do not add their own elementary predicate, but serve to constrain which argument of the predicate they modify is filled by their complement.

Other postpostions are two place predicates, where the thing they modify (typically appearing on the right) is the external argument (ARG1) and their complement is the ARG2: ARG2のARG1, ARG1はARG2.

Predicates with preposition type semantics are introduced by some rules:

• relative-clause-rule which introduces topic_p_rel with the verb as ARG1 and the noun as ARG2.

• wh-adv-sem-type which introduces unspec_p_manner_rel

• adv_np_rule-type which introduces unspec_p_rel, changing date nouns into pps.
