[Instruction]
This paper proposes a novel neural network for explainable fake news detection based on raw reports from different media outlets. The proposed model consists of a hierarchical encoder for web text representation, and two cascaded selectors to select the most explainable sentences for verdicts. The proposed method outperforms state-of-the-art detection baselines and generates high-quality explanations from diverse evaluation perspectives. The paper also presents two explainable fake news datasets, which are publicly available.

1. Could the authors provide more detailed information on the implementation process of the proposed method?
2. Could the authors conduct more extensive evaluation and ablation studies to support the proposed method's performance?
3. Could the authors compare the proposed method with more widely-known baselines in the field?

[Ground truth Answer]
Thank you for your questions and interest in the proposed method. To address your concerns:

1. Implementation details: While the provided summary offers a high-level overview of the proposed model, a more detailed account can be found in the full paper. The hierarchical encoder in the proposed model is responsible for extracting features from raw web text, which includes representing sentences as vectors to capture both semantic and word-level information. The cascaded selectors, on the other hand, focus on selecting the most explainable sentences based on relevance and representativeness. For training, the model optimizes the global objective function using gradient-based approaches. The neural network architectures and hyperparameters can be tuned according to the specific dataset and application.

2. Evaluation and ablation studies: Additional evaluation and ablation studies can be conducted to further support the proposed method's performance. For instance, the authors can explore different combinations of the model's components or varying the dataset sizes to understand their impact on the model's performance. Comparisons can also be made with alternative feature extraction and selection methods, and different evaluation metrics can be employed to provide a more comprehensive understanding of the model's capabilities.

3. Comparison with widely-known baselines: It would indeed be beneficial to compare the proposed method with more widely-known baselines in the field to demonstrate its efficacy. The authors can incorporate existing methods such as support vector machines, logistic regression, or other popular deep learning techniques in the experiments to provide a broader and more meaningful comparison. By doing so, the study's relevance and impact can be better understood, and the advantages of the proposed model can be more effectively demonstrated.

I hope this clarifies your concerns and provides further information on the proposed method. If you have any more questions, please do not hesitate to reach out!

The paper presents an innovative approach to fake news detection by leveraging a neural network model that emphasizes explainability. Here are some suggestions for enhancing the paper's contributions and clarity:

1. **Detailed Implementation Information**: The authors could enrich the paper by providing comprehensive details about the implementation of their proposed model. This includes a thorough description of the hierarchical encoder's architecture, specifying the neural network layers and configurations utilized. Details about the training process, such as dataset preparation, hyperparameter settings, and optimization techniques, should be clearly outlined. Additionally, information on the computational resources required and any software frameworks or libraries employed would be beneficial for replicability and understanding of the method.

2. **Extensive Evaluation and Ablation Studies**: To bolster the claims of the model's performance, the authors could conduct more extensive evaluation and ablation studies. These studies should aim to isolate and assess the impact of different components of the model, such as the hierarchical encoder and cascaded selectors. Testing the model on various subsets of the datasets can help evaluate its robustness and generalizability. Including statistical significance tests and error analysis would further substantiate the evaluation, providing deeper insights into the model's strengths and areas for improvement.

3. **Comparison with Established Baselines**: For a comprehensive assessment of the proposed method's effectiveness, it would be advantageous to compare it with more widely-known baselines in the field. Including comparisons with traditional machine learning models, such as support vector machines or logistic regression, as well as other neural network-based models like LSTM or BERT-based architectures, would provide a clearer picture of the relative performance and improvements offered by the proposed method. This comparison would contextualize the advancements made and highlight the unique benefits of the approach.

By addressing these points, the authors can enhance the transparency, reliability, and impact of their research, making it more accessible and valuable to the scientific community and practitioners in the field of fake news detection.
