| Pseudocode | No | The paper describes the generative process of the model in numbered textual steps but does not present it as a formal 'Pseudocode' or 'Algorithm' block. |
| Open Source Code | No | The paper does not provide any statement or link indicating that the source code for the described methodology is open-source or publicly available. |
| Open Datasets | Yes | Review dataset The first dataset is a collection of movie reviews. A subset of this collection has been used in (Pang and Lee 2005). |
| Dataset Splits | No | The paper mentions evaluating on a 'test set' but does not provide specific details on training, validation, or test dataset splits (e.g., percentages or counts). |
| Hardware Specification | No | The paper does not provide specific details about the hardware (e.g., CPU, GPU models, memory) used to run the experiments. |
| Software Dependencies | No | The paper mentions using Lib SVM for classification but does not provide specific version numbers for any software dependencies. |
| Experiment Setup | Yes | Figure 3 shows the accuracy of our model in comparison with all the baselines in different numbers of latent factors. ... The proposed SUIT model achieves best result when the number is equal to 40. |
