 Description

NL2SH (Natural Language to Semantic Hypergraph) dataset can be used to build and evaluate methods for knowledge extraction and representation based on a semantic hypergraph. Each sentence has natural language annotations and dedicated semantic hyperedge. Majority of the sentences used in this dataset are taken from the following sources: * John Eastwood, Oxford Guide to English Grammar, Oxford University Press, 2002. * Andrew Redford, An Introduction to English Sentence Structure, Cambridge University Press, 2009. * Essential English Grammar, Philip Gucker, Dover Publications, Inc. New York, 1966 Natural language annotations are: * sent_i - id of the sentence * tok_i - id of the token in the sentence * word - token text * space - does space follows the token * lemma - lemma of the token * pos - Universal POS tags (https://universaldependencies.org/u/pos/) * tag - Penn Treebank tags (https://www.ling.upenn.edu/courses/Fall_2003/ling001/penn_treebank_pos.html) * dep - ClearNLP depedency labels (https://github.com/clir/clearnlp-guidelines/blob/master/md/specifications/dependency_labels.md) * head - id of the token which is a dependency head of the current token * ner - named entities (https://catalog.ldc.upenn.edu/docs/LDC2013T19/OntoNotes-Release-5.0.pdf) * roleset - roleset of a verb frame (https://propbank.github.io/v3.4.0/frames/) * srl - semantic role labels with IOB annotation (https://verbs.colorado.edu/propbank/EPB-Annotation-Guidelines.pdf) * coref - coreference labels with IOB annotation * synset - WordNet's synsets (https://wordnet.princeton.edu) The annotations for semantic hypergraph elements primarily adhere to the annotation guidelines of the Graphbrain project (https://graphbrain.net/manual/notation.html). However, atom annotations are modified and at the end contains: * label, * type and optional subtype, * type specific atom roles, * type specific additional information, * named entity
