Beschreibung

PAC is a predicate-argument clustering software that is trained on predicate-frame-argument tuples and outputs a multi-dimensional cluster analysis, including clusters for the predicates and selectional preference abstraction over the predicate arguments.

PAC is trained on tuples such as

2 abandon SUBJ:NP company project
1 abstain SUBJ legislator
1 accede SUBJ:P:NP government to pact

and induces a statistical soft clustering of these (and other) tuples.
