CompactIE

Source code for NAACL 2022 paper "CompactIE: Compact Facts in Open Information Extraction", which extracts compact facts from raw input sentences. Our pipelined approach consists of two models, Constituent Extraction and Constituent Linking. The Constituent Extraction model first extracts triple slots (constituents) and pass them to Constituent Linking models to link the constituents and form triples.

Requirements

• python: 3.6
• pytorch: 1.9.0
• transformers: 4.2.2
• configargparse: 1.2.3
• bidict: 0.20.0

Datasets

The scripts and instructions for downloading and processing our benchmark are provided in data/.

Training

Constituent Extraction Model

python constituent_model.py \
    --config_file constituent_model_config.yml \
    --device 0

Constituent Linking Model

python linking_model.py \
    --config_file linking_model_config.yml \
    --device 0

Note that first the data for these models should be provided and processed (as described in data/) and then each model can be trained individually.
If OOM occurs, we suggest that reducing train_batch_size and increasing gradient_accumulation_steps (gradient_accumulation_steps is used to perform Gradient Accumulation).

Inference

After training and saving the Constituent Extraction and Constituent Linking models, test the pipelined CompactIE on evaluation benchmarks. Three popular evaluation benchmarks (BenchIE, CaRB, Wire57) are provided to examine CompactIE's performance.

python test.py --config_file config.yml

To test the CompactIE system on a set of sentences, first process those sentences as described here. Then, modify the config.yml file so that the path to the processed sentence file (test_file) and its conjunction file (conjunctions_file) is properly reflected. Finally, run the above command to produce extractions.

Pre-trained Models

Models checkpoint are available in Zenodo. Download the Constituent Extraction (ce_model) model and put in under save_results/models/constituent/ folder. Download the Constituent Linking (cl_model) model and put in under save_results/models/relation/ folder.

    abstract = "A major drawback of modern neural OpenIE systems and benchmarks is that they prioritize high coverage of information in extractions over compactness of their constituents. This severely limits the usefulness of OpenIE extractions in many downstream tasks. The utility of extractions can be improved if extractions are compact and share constituents. To this end, we study the problem of identifying compact extractions with neural-based methods. We propose CompactIE, an OpenIE system that uses a novel pipelined approach to produce compact extractions with overlapping constituents. It first detects constituents of the extractions and then links them to build extractions. We train our system on compact extractions obtained by processing existing benchmarks. Our experiments on CaRB and Wire57 datasets indicate that CompactIE finds 1.5x-2x more compact extractions than previous systems, with high precision, establishing a new state-of-the-art performance in OpenIE.",
