### Dataset Sources

- **Repository:** https://github.com/dlt-science/ESG-DLT-LitReview
- **Paper:** https://arxiv.org/abs/2308.12420

## Use

This dataset can be used for training and evaluating Named Entity Recognition models focused on DLT and ESG topics. It's particularly useful for researchers and practitioners working on text mining and information extraction in these domains.

## Dataset Structure

The dataset contains 39,427 named entities organized into 12 top-level categories with 136 labels in a tree structure. It includes entities related to blockchain names, consensus mechanisms, transaction capabilities, security and privacy, and ESG concepts.

### Label ID
The label2id dictionary is:

```python
    {
        "O": 0,
        "B-Blockchain_Name": 1,
        "I-Blockchain_Name": 2,
        "B-Codebase": 3,
        "I-Codebase": 4,
        "B-Consensus": 5,
        "I-Consensus": 6,
        "B-ChargingAndRewardingSystem": 7,
        "I-ChargingAndRewardingSystem": 8,
        "B-ESG": 9,

        "B-Security_Privacy": 21,
        "I-Security_Privacy": 22,
        "B-Transaction_Capabilities": 23,
        "I-Transaction_Capabilities": 24
    }
```

## Dataset Creation

### Curation Rationale

The dataset was created to address the scarcity of labeled NLP data for blockchain research, focusing on the intersection of DLT and ESG topics.

### Source Data

#### Data Collection and Processing

The dataset was created by manually annotating 80 publicly available publications using the brat tool and argilla. The taxonomy framework from [Tasca and Tessone (2019)](https://ledger.pitt.edu/ojs/ledger/article/view/140) was extended to include ESG-related concepts.

### Annotations

#### Annotation process

The annotation process involved manual labeling using the brat tool and argilla, following an extended version of the [Tasca and Tessone (2019) taxonomy](https://ledger.pitt.edu/ojs/ledger/article/view/140). Inter-labeler consistency was improved through systematic processes and programmatic cleaning.

#### Who are the annotators?

The annotators are the research paper's authors and other collaborators involved in the project.

#### Personal and Sensitive Information

The dataset does not contain personal or sensitive information as it is based on publicly available academic publications.

## Bias, Risks, and Limitations

### Recommendations

Users should be aware of potential biases in the dataset due to the selection of source publications and the annotation process.
