OpenCCG Description

OpenNLP CCG (Combinatory Categorial Grammar) Library OpenCCG, the OpenNLP CCG Library, is a collection of natural language processing components and tools which provide support for parsing and realization with Combinatory Categorial Grammar (CCG). The OpenCCG library uses multi-modal extensions to CCG. Requirements: · Java What's New in This Release: · Added check for unary rule cycles in parser and realizer. · Added initial version of greedy fragment assembly in realization when a complete realization is not found. · Added case for composition of X/Y Y/Z where Y has arity 2. · Added option to filter rule apps by observed supercat-rule combos. · VisCCG: Please see the list of changes in the archives at http://comp.ling.utexas.edu/wiki/doku.php/openccg/dev · Added LexSemOrigin interface for tracking of origin of lexical predications back to a sign or unary type changing rule. · Removed unused LF in DataItem. · Added supertagger-based filtering to lexical lookup. · Upgraded to JDOM 1.1. · Upgraded parser to use ambiguity packing. · Added scoring and n-best pruning to parser. · Refactored SignScorer to synsem package, for shared use by the realizer and parser. NB: This may require minor refactoring of imports and recompilation of realizer clients. · Changed realizer to check instantiation of outermost args by default, thereby improving completness at minor cost to efficiency. Accordingly, renamed checkInstantiation flag in EdgeFactory to debugInstantiation, which now controls whether to report such cats to System.err. · Added hypertagger (realizer supertagger) interface and initial version of beta-best realization using it. · Changed Family.deriveSupertag to remove the semantic part of a cat name following a colon.
