# Model description |
|
|
|
This is the T5-3B model for System 1 as described in our paper Just-DREAM-about-it: Figurative Language Understanding with DREAM-FLUTE, FigLang workshop @ EMNLP 2022 (Arxiv link: https://arxiv.org/abs/2210.16407) |
|
|
|
System 1: Using original data |
|
|
|
Given the <Premise, Hypothesis, Label, Explanation> in the original data, we first trained a sequence-to-sequence model for the figurative language NLI task |
|
using the following input-output format: |
|
``` |
|
Input <Premise> <Hypothesis> |
|
Output <Label> <Explanation> |
|
``` |
|
|
|
# How to use this model? |
|
We provide a quick example of how you can try out System 1 in our paper with just a few lines of code: |
|
``` |
|
>>> from transformers import AutoTokenizer, AutoModelForSeq2SeqLM |
|
>>> model = AutoModelForSeq2SeqLM.from_pretrained("allenai/System1_FigLang2022") |
|
|
|
>>> tokenizer = AutoTokenizer.from_pretrained("t5-3b") |
|
>>> input_string = "Premise: My neighbor actually purchased a dream car of mine and I see it parked in his driveway everyday just taunting me. Hypothesis: My neighbor's new car is exactly my dream car, and I feel so happy every time I see it parked in his driveway. Is there a contradiction or entailment between the premise and hypothesis?" |
|
>>> input_ids = tokenizer.encode(input_string, return_tensors="pt") |
|
>>> output = model.generate(input_ids, max_length=200) |
|
>>> tokenizer.batch_decode(output, skip_special_tokens=True) |
|
["Answer : Contradiction. Explanation : Most people would not be happy to see someone else's new car that they cannot afford because it is way out of their budget"] |
|
``` |

## Training and evaluation data |
|
|
|
We use the FLUTE dataset for the FigLang2022SharedTask (https://huggingface.co/datasets/ColumbiaNLP/FLUTE) for training this model. ∼7500 samples are provided as the training set. We used a 80-20 split to create our own training (6027 samples) and validation (1507 samples) partitions on which we build our models. For details on how we make use of the training data provided in the FigLang2022 shared task, please refer to https://github.com/allenai/dream/blob/main/FigLang2022SharedTask/Process_Data_Train_Dev_split.ipynb. |
