# Dataset Card for "SciEntsBank"

SciEntsBank is one of the two distinct subsets within the Student Response Analysis (SRA) corpus, the other subset being the
[Beetle](https://huggingface.co/datasets/nkazi/Beetle) dataset. Derived from student answers gathered by Nielsen et al. [1],
this dataset comprises nearly 11K responses to 197 assessment questions spanning 15 diverse science domains. The dataset
features three labeling schemes: (a) 5-way, (b) 3-way, and (c) 2-way. The dataset includes a training set and three distinct
test sets: (a) Unseen Answers (`test_ua`), (b) Unseen Questions (`test_uq`), and (c) Unseen Domains (`test_ud`).

## Loading Dataset

```python
from datasets import load_dataset
dataset = load_dataset('nkazi/SciEntsBank')
```

## Labeling Schemes

The authors released the dataset with annotations using five labels (i.e., 5-way labeling scheme) for Automated Short-Answer Grading (ASAG).
Additionally, the authors have introduced two alternative labeling schemes, namely the 3-way and 2-way schemes, both derived from the 5-way
labeling scheme designed for Recognizing Textual Entailment (RTE). In the 3-way labeling scheme, the categories "partially correct but
incomplete", "irrelevant", and "non-domain" are consolidated into a unified category labeled as "incorrect". On the other hand, the 2-way
labeling scheme simplifies the classification into a binary system where all labels except "correct" are merged under the "incorrect" category.

The `label` column in this dataset presents the 5-way labels. For 3-way and 2-way labels, use the code provided below to derive it
from the 5-way labels. After converting the labels, please verify the label distribution. A code to print the label distribution is
also given below.

### 5-way to 3-way

```python
from datasets import ClassLabel

dataset = dataset.align_labels_with_mapping({'correct': 0, 'contradictory': 1, 'partially_correct_incomplete': 2, 'irrelevant': 2, 'non_domain': 2}, 'label')
dataset = dataset.cast_column('label', ClassLabel(names=['correct', 'contradictory', 'incorrect']))
```

Using `align_labels_with_mapping()`, we are mapping "partially correct but incomplete", "irrelevant", and "non-domain" to the same id. Subsequently,
we are using `cast_column()` to redefine the class labels (i.e., the label feature) where the id 2 corresponds to the "incorrect" label.

### 5-way to 2-way

```python
from datasets import ClassLabel

dataset = dataset.align_labels_with_mapping({'correct': 0, 'contradictory': 1, 'partially_correct_incomplete': 1, 'irrelevant': 1, 'non_domain': 1}, 'label')
dataset = dataset.cast_column('label', ClassLabel(names=['correct', 'incorrect']))
```

In the above code, the label "correct" is mapped to 0 to maintain consistency with both the 5-way and 3-way labeling schemes. If the preference is to
represent "correct" with id 1 and "incorrect" with id 0, either adjust the label map accordingly or run the following to switch the ids:

```python
dataset = dataset.align_labels_with_mapping({'incorrect': 0, 'correct': 1}, 'label')
```

### Saving and loading 3-way and 2-way datasets

Use the following code to store the dataset with the 3-way (or 2-way) labeling scheme locally to eliminate the need to convert labels each time the dataset is loaded:

```python
dataset.save_to_disk('SciEntsBank_3way')
```

Here, `SciEntsBank_3way` depicts the path/directory where the dataset will be stored. Use the following code to load the dataset from the same local directory/path:

```python
from datasets import DatasetDict
dataset = DatasetDict.load_from_disk('SciEntsBank_3way')
```

### Printing Label Distribution

Use the following code to print the label distribution:

```python
def print_label_dist(dataset):
    for split_name in dataset:
        print(split_name, ':')
        num_examples = 0
        for label in dataset[split_name].features['label'].names:
            count = dataset[split_name]['label'].count(dataset[split_name].features['label'].str2int(label))
            print(' ', label, ':', count)
            num_examples += count
        print('  total :', num_examples)

print_label_dist(dataset)
```
