Treebank Semantics —
Meaning Representations from Treebanks

What is Treebank Semantics?

Treebank Semantics is an implemented system that automatically derives meaning representations of quality from treebank annotations. The central component is a system of calculation for a small formal language with respect to a structured information state. Inputs to the system are expressions of the formal language obtained from the conversion of parsed treebank data. Outputs are predicate logic based meaning representations. There is a manual that describes the approach and implementation in detail.

The system is distributed freely.

To see ready made examples, web based interfaces are provided to the following parsed corpora:

These parsed corpora provide a testing ground for the system, with meaning representations built automatically by the system from treebank files.

Getting started

The core program is implemented in Prolog and requires a working ECLiPSe Constraint Programming System. Another requirement is to have stanford-tregex.jar.

After download, run the do_it command located in the ./bin folder.

do_it takes parse tree input from stdin and sends its calculations to stdout. do_it has the following flags:

--discourse|-d) treat input as single discourse
--debug) debug <normalised_expr> creation
--basic|-s) return <normalised_expr> (that is, input for run_ts2 or term_ts2)
--norm|-1) print <normalised_expr>
--sct|-2) print <sct_expr> (this is the default output mode)
--raw|-3) print <target_expr> with <drs_expr> structures
--drs|-4) print final <target_expr>
--conjec*) return TPTP conjecture
--axiom|--tptp|-t) return TPTP axiom(s)
--flo*) return FLOTTER output
--clause|-c) return clause representation
--cdebug|-cdebug) debug clause representation
--craw|-craw) see XML used to create clause representation
--raw|-r|--xml|-x) return raw XML
--native) skip parse_modify
