[Evidentiality-guided Generation for Knowledge-Intensive NLP Tasks](https://aclanthology.org/2022.naacl-main.162/). In Proc. NAACL. 2021. In this paper, we introduce **Evidentiality-guided Generator**, which incorporates evidentiality of passages---whether a passage contains correct evidence to support the output---into training the generator via multi-task learning of answer generation and evidentiality prediction for retrieval-augmented generation. Experimental results show large improvements across three knowledge intensive tasks: open question answering, fact verification and knowledge-enhanced dialogue. ## Directories - [`evi_gen`](evi_gen): codes for our evidentiality-guided generator model. The implementation is built upon [Fusion-in-Decoder (Izacard and Grave, 2020)](https://github.com/facebookresearch/FiD). - [`mining`](mining): code for our evidentiality labeling model used to obtain silver evidentiality data. Please see the training and evaluation details in each directories. ## Data and Models ### Retrieved data (train / dev / test ) We release the DPR retrieved results and the results with our silver evidentiality labels. All of the data can be downloaded from [here](https://drive.google.com/drive/folders/1PA4NEJr3W1JXNvofJYBlTo5nyyGkMqRL?usp=sharing). - [`evidentiality_dpr.zip`](https://drive.google.com/file/d/1BnWMB9XS63HPRVq7eWYJ3h4JvVsfr6-5/view?usp=sharing) includes the retrieval results with our newly mined silver evidentiality labels for train sets for each target dataset. For each query, we include top 20 passages. - [`eval_dpr.zip`](https://drive.google.com/file/d/1hXr04jaGuapqpcaROsM3xsSyQ100F6zd/view?usp=sharing) includes the retrieval results for dev / test sets for each target dataset. ### Fine-tuned models You can download the fine-tuned models from the google drive repositories. - [NQ Open](https://drive.google.com/file/d/16bio8wIvbIj7OmWqaiBzGFEHBFB6AlY6/view?usp=sharing) - [TriviaQA unfiltered](https://drive.google.com/file/d/1YskriNt9LMUUZnGqSbhlE4Cyiz8CSaPG/view?usp=sharing) - [FaVIQ unfiltered](https://drive.google.com/file/d/1OnFxXzJTWbu_rWylDmS0P8gXHMZJPGbW/view?usp=sharing) - [FEVER unfiltered](https://drive.google.com/file/d/19qa1vr4ng_GAqGcygr5ErCuSh5fnqhpr/view?usp=sharing) - [WoW](https://drive.google.com/file/d/10RsFfGgzsSC9MOb3Csoc1ztUp0NJSoGy/view?usp=sharing) ## Evaluations To reproduce the original results, you can go to `evi_gen` directory and then run the command below: ``` CUDA_VISIBLE_DEVICES=0 python test_reader.py \ --model_path model/nq_ours \ --eval_data data/nq_test.json \ --per_gpu_batch_size 48 \ --n_context 20 \ --name sanity_nq_test \ --checkpoint_dir checkpoint \ --n_gpus 1 \ --write_results ``` For WoW, please set the `--metric f1` ## Training ### Overview of Training Our evidentiality-guided generator will conduct a multi-task learning of evidentiality prediction and generation. To supervised this learning, we need to obtain *silver* evidentiality data. Our training procedures are as follows: 1. Training a base Fusion-in-Decoder model (*base generator*) 2. Run leave-one-out generation approach to collect training data for evidentiality labeling model (M) using the base generator. 3. Train M using data from step 2. 4. Run M on all of the passages included in training data for a evidentiality-guided generator to obtain silver evidentiality labels. 5. Train the evidentiality-guided generator with the multi-task loss. See more detailed instructions in the `evi_gen` and `mining` directories. ### Training our evidentiality generator If you want to quickly start training our evidentiality-guided generator, we provide the resulting training data [here](https://drive.google.com/file/d/1BnWMB9XS63HPRVq7eWYJ3h4JvVsfr6-5/view?usp=sharing).
