The main objective of this project is to develop a dependency representation that is coherent across syntactic variations and gives complete predicate argument structures including non-verbal predicates as well as external arguments. The project is under the [Apache 2](http://www.apache.org/licenses/LICENSE-2.0) license and developed by the [Emory NLP](http://nlp.mathcs.emory.edu) research group. 4 | 5 | ## Resources 6 | 7 | * [DDG Guidelines](https://emorynlp.github.io/ddr/doc). 8 | * [DDG Conversion](https://github.com/elitcloud/elit-java/tree/master/elit-ddr). 9 | * [DDG Visualization](https://emorynlp.github.io/ddr/viz). 10 | 11 | 12 | ## Citation 13 | 14 | * [Deep Dependency Graph Conversion in English]().
