OntoED and OntoEvent

OntoED: A Model for Low-resource Event Detection with Ontology Embedding

🍎 The project is an official implementation for OntoED model and a repository for OntoEvent dataset, which has firstly been proposed in the paper OntoED: Low-resource Event Detection with Ontology Embedding accepted by ACL 2021.

🤗 The implementations are based on Huggingface's Transformers and remanagement is referred to MAVEN's baselines & DeepKE.

🤗 We also provide some baseline implementations for reproduction.

Brief Introduction

OntoED is a model that resolves event detection under low-resource conditions. It models the relationship between event types through ontology embedding: it can transfer knowledge of high-resource event types to low-resource ones, and the unseen event type can establish connection with seen ones via event ontology.

Requirements

python==3.6.9
torch==1.8.0 (lower may also be OK)
transformers==2.8.0
sklearn==0.20.2

Usage

1. Project Preparation：Download this project and unzip the dataset. You can directly download the archive, or run git clone https://github.com/231sm/Reasoning_In_EE.git at your teminal.

cd [LOCAL_PROJECT_PATH]

git clone https://github.com/231sm/Reasoning_In_EE.git

2. Running Preparation: Adjust the parameters in run_ontoed.sh bash file, and input the true path of 'LABEL_PATH' and 'RELATION_PATH' at the end of data_utils.py.

cd Reasoning_In_EE/OntoED

vim run_ontoed.sh
(input the parameters, save and quit)

vim data_utils.py
(input the path of 'LABEL_PATH' and 'RELATION_PATH', save and quit)

Hint:

Please refer to main() function in run_ontoed.py file for detail meanings of each parameters.
'LABEL_PATH' and 'RELATION_PATH' means the path for event_dict_train_data.json and event_relation.json respectively.

3. Running Model: Run ./run_ontoed.sh for training, validation, and testing. A folder with configuration, models weights, and results (in is_test_true_eval_results.txt) will be saved at the path you input ('--output_dir') in the bash file run_ontoed.sh.

cd Reasoning_In_EE/OntoED

./run_ontoed.sh
('--do_train', '--do_eval', '--evaluate_during_training', '--do_test' is necessarily input in 'run_ontoed.sh')

Or you can run run_ontoed.py with manual parameter input (parameters can be copied from 'run_ontoed.sh')

python run_ontoed.py --para...

How about the Dataset

OntoEvent is proposed for ED and also annotated with correlations among events. It contains 13 supertypes with 100 subtypes, derived from 4,115 documents with 60,546 event instances. Please refer to OntoEvent for details.

Statistics

The statistics of OntoEvent are shown below, and the detailed data schema can be referred to our paper.

Dataset	#Doc	#Instance	#SuperType	#SubType	#EventCorrelation
ACE 2005	599	4,090	8	33	None
TAC KBP 2017	167	4,839	8	18	None
FewEvent	-	70,852	19	100	None
MAVEN	4,480	111,611	21	168	None
OntoEvent	4,115	60,546	13	100	3,804

Data Format

The OntoEvent dataset is stored in json format.

🍒For each event instance in event_dict_data_on_doc.json, the data format is as below:

{
    'doc_id': '...', 
    'doc_title': 'XXX', 
    'sent_id': , 
    'event_mention': '......', 
    'event_mention_tokens': ['.', '.', '.', '.', '.', '.'], 
    'trigger': '...', 
    'trigger_pos': [, ], 
    'event_type': ''
}

🍒For each event relation in event_relation.json, we list the event instance pair, and the data format is as below:

'EVENT_RELATION_1': [ 
    [
        {
            'doc_id': '...', 
            'doc_title': 'XXX', 
            'sent_id': , 
            'event_mention': '......', 
            'event_mention_tokens': ['.', '.', '.', '.', '.', '.'], 
            'trigger': '...', 
            'trigger_pos': [, ], 
            'event_type': ''
        }, 
        {
            'doc_id': '...', 
            'doc_title': 'XXX', 
            'sent_id': , 
            'event_mention': '......', 
            'event_mention_tokens': ['.', '.', '.', '.', '.', '.'], 
            'trigger': '...', 
            'trigger_pos': [, ], 
            'event_type': ''
        }
    ], 
    ...
]

🍒Especially for "COSUPER", "SUBSUPER" and "SUPERSUB", we list the event type pair, and the data format is as below:

"COSUPER": [
    ["Conflict.Attack", "Conflict.Protest"], 
    ["Conflict.Attack", "Conflict.Sending"], 
    ...
]
