Quality Controlled Paraphrase Generation (ACL 2022)

Paraphrase generation has been widely used in various downstream tasks. Most tasks benefit mainly from high quality paraphrases, namely those that are semantically similar to, yet linguistically diverse from, the original sentence. Generating high-quality paraphrases is challenging as it becomes increasingly hard to preserve meaning as linguistic diversity increases. Recent works achieve nice results by controlling specific aspects of the paraphrase, such as its syntactic tree. However, they do not allow to directly control the quality of the generated paraphrase, and suffer from low flexibility and scalability.

Here we propose QCPG, a quality-guided controlled paraphrase generation model, that allows directly controlling the quality dimensions. Furthermore, we suggest a method that given a sentence, identifies points in the quality control space that are expected to yield optimal generated paraphrases. We show that our method is able to generate paraphrases which maintain the original meaning while achieving higher diversity than the uncontrolled baseline.

Training, Evaluation and Inference

The code for training, evaluation and inference for both QCPG and QP is located in the dedicated directories. Scripts necassery for reproducing the experiments can be found in the QCPG/scripts, QP/scripts directories.

Make sure to run QCPG/scripts/prepare_data.sh and set the missing datasets directories accordingly before training!

Trained Models

!!! Notice !!! Our results show that on avarage QCPG is follwing the quality conditions and capable of generating higher quality greedy-sampled paraphrases then finetuned model. It does not mean it will output perfect paraphrases all the time!!! In practice, for best preformence, we highly reccomend: (1) Find the right quality control values (2) Use more sophisticated sampling methods (3) Apply post-generation monitoring and filtering.

qcpg-sentences (Trained on data/parabk2)

qcpg-captions (Trained on data/mscoco)

Usage

The best way to use the model is with the following code:

from transformers import pipeline

class QualityControlPipeline:
    
    def __init__(self, type):
        assert type in ['captions', 'questions', 'sentences']
        self.pipe = pipeline('text2text-generation', model=f'ibm/qcpg-{type}')
        self.ranges = {
            'captions': {'lex': [0, 90], 'syn': [0, 80], 'sem': [0, 95]},
            'sentences': {'lex': [0, 100], 'syn': [0, 80], 'sem': [0, 95]},
            'questions': {'lex': [0, 90], 'syn': [0, 75], 'sem': [0, 95]}
        }[type]

    def __call__(self, text, lexical, syntactic, semantic, **kwargs):
        assert all([0 <= val <= 1 for val in [lexical, syntactic, semantic]]), \
                 f' control values must be between 0 and 1, got {lexical}, {syntactic}, {semantic}'
        names = ['semantic_sim', 'lexical_div', 'syntactic_div']
        control = [int(5 * round(val * 100 / 5)) for val in [semantic, lexical, syntactic]]
        control ={name: max(min(val , self.ranges[name[:3]][1]), self.ranges[name[:3]][0]) for name, val in zip(names, control)}
        control = [f'COND_{name.upper()}_{control[name]}' for name in names]
        assert all(cond in self.pipe.tokenizer.additional_special_tokens for cond in control)
        text = ' '.join(control) + text if isinstance(text, str) else [' '.join(control) for t in text]
        return self.pipe(text, **kwargs)

Loading:

model = QualityControlPipeline('sentences')

Generation with quality controlls:

model('Is this going to work or what are we doing here?', lexical=0.3, syntactic=0.5, semantic=0.8)

Output: [{'generated_text': "Will it work or what is it we're doing?"}]

Out-of-Scope Use

The model should not be used to intentionally create hostile or alienating environments for people.

Bias, Risks, and Limitations

Significant research has explored bias and fairness issues with language models (see, e.g., Sheng et al. (2021) and Bender et al. (2021)). Predictions generated by the model may include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups.

Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

Training Details

Training Data

The model creators note in the associated paper:

These datasets are large but noisy, and contain only a relatively small amount of high quality paraphrases. MSCOCO: This dataset consists of 123K im- ages, where each image contains at most five human-labeled captions (Lin et al., 2014). Similar to previous works we consider different captions of the same image as paraphrases. WikiAnswers (WikiAns for short): The WikiAnswers corpus contains clusters of ques- tions tagged by wiki-answers.com users as similar. There are 30, 370, 994 clusters with 25 question in each on average. In total, the corpus contains over 70 million question pairs ParaBank2.0: A dataset containing clusters of sentential paraphrases, produced from a bilingual corpus using negative constraints, inference sam- pling, and clustering. The dataset is composed of avarage of 5 paraphrases in every cluster and close to 100 million pairs in total.

Training Procedure

Preprocessing

The model creators note in the associated paper:

To get comparable results across all datasets, we randomly sub-sampled ParaBank2.0 and WikiAns to the same size as MSCOCO, and split them to train, dev and test sets, of sizes 900K, 14K and 14K respectively. We carefully made sure that there are no pairs from the same cluster in differ- ent splits of the data.

Speeds, Sizes, Times

The model creators note in the associated paper:

All models are trained with batch size of 32 on 2 NVIDIA A100 GPUs for 6 epochs.
