DptOIE and Models

DptOIE method uses the Dependence Parser and Part of Speech Tagger models trained with Stanford CoreNLP.

This project contains:

• DptOIE's source code: An Open Information Extraction for Portuguese language.
• Dependence Parser and Part of Speech Tagger models trained with Stanford CoreNLP.

Prerequisites to run from source code

• Dataset CETEN200, WIKI200 and models
• Insert the file pt-dep-parser.gz in pt-models directory
• Import as Maven Project in Eclipse IDE

How to use

To run the DptOIE.jar

 java -jar DptOIE.jar -sentencesIN **sentences_file_path**

To use the module that handles subordinate clause

-SC true

To use the module that handles coordinated conjunctions

-CC true

To use the module that handles appositive

-appositive 1

To apply transitivity

-appositive 2

DptOIE is independent of dependency parser, so it can receive annotated sentences with other dependency parsers, as long as they are in ConLL-U format with the same tagsets of the Google treebank Treebanks Universal V2,1.

To run DptOIE from a dependency tree in ConLL-U format

java -jar DptOIE.jar -sentencesIN 'sentences_file_path' -dependencyTreeIN 'dependency_Tree_conllu_format'
