# ECSS-1.0 Dataset
## Dataset Summary
This dataset provides a focused benchmark for retrieval and generation tasks related to ECSS (European Cooperation for Space Standardization) documents. It includes a set of documents, queries, relevance judgments (qrels), and page images.
- Number of Documents: 196
- Number of Queries: 67
- Number of Pages: 22700
- Number of Relevance Judgments (qrels): 89
- Average Number of Pages per Query: 1.3
## Dataset Structure (Hugging Face Datasets)
The dataset is structured into the following subsets:
- `corpus`: Contains page-level information:
- `_id`: A unique identifier for this specific page within the corpus.
- `title`: The title of the document.
- `text`: The text of the document.
- `queries`: Contains query information:
- `_id`: Unique identifier for the question.
- `query_text`: The question text.
- `relevant_document_ids`: A list of corpus documents considered as references for this question, each reference containing:
- `corpus_id`: The document identifier.
- `score`: The importance or relevance score.
## Usage Examples
You can load the datasets using the `load_from_disk` function from the `datasets` library. Replace the paths with the actual locations on your machine.
```python
from datasets import load_dataset
dataset_queries_test = load_dataset("FOR-sight-ai/ECSS-1.0", "queries", split="test")
```
