Contributions

1. Decomposed the WebNLG dataset from document-level into sentence-level
2. Created an Easy-to-use Python reader for WebNLG dataset v1.5, runnable by 2019-SEP-20. (Debugged and adapted from the reader in chimera's repo.)
3. Manually fixed spaCy's sentence tokenization
4. Deleted parts of sentences where no corresponding triple exists.
5. Deleted irrelevant triples manually
6. Manually fixed all wrong templates (e.g. template.replace('AEGNT-1', 'AGENT-1')), made it convenient for template-based models.
7. Carefully replaces - with _ in template names, such as AGENT-1 to AGENT_1. This provides convenience for tokenization.

• Vocab of ner: 12 (['agent_1', 'bridge_1', 'bridge_2', 'bridge_3', 'bridge_4', 'patient_1', 'patient_2', 'patient_3', 'patient_4', 'patient_5', 'patient_6', 'patient_7'])
• Vocab of relations: 726
• Vocab of txt: 6671
• Vocab of tgt: 1897
• Len(tgt): avg 11.5, max 42

Todo

• "was selected by NASA" is a relationship which spans several words, -- it should be made as one word in the triple.
• "(workedAt," is a relationship which has punctuations, -- it should be clean.
• There are still several hundred dirty, unaligned (stripleset, template) pairs. Align them by tracking the self.cnt_dirty_data variable when running reader.py.
• 'discrimina-tive training' spelling errors
• fix unalignment errors by grep -nriF '<sentence ID="3"/>' '<sentence ID="2"/>'
