# Problem to Full Patent Retrieval

## Dataset Description

This dataset is part of **PatenTEB**, a comprehensive benchmark for evaluating text embedding models on patent-specific tasks. PatenTEB comprises 15 tasks across retrieval, classification, paraphrase detection, and clustering, with 2.06 million examples designed to reflect real-world patent analysis workflows.

**Paper**: [PatenTEB: A Comprehensive Benchmark and Model Family for Patent Text Embedding](https://arxiv.org/abs/2510.22264)

### Task Details

- **Task Name**: `problem2full`
- **Task Type**: Retrieval
- **Test Samples**: 18,729

Asymmetric retrieval task retrieving full patent documents using problem descriptions as queries.
Tests whether models recognize that different patents addressing the same technical problem may use varied terminology and solutions.
Fragment removal prevents trivial matching.

### Dataset Structure

This is a retrieval task where models find relevant patents given a query.

**Splits:**
- `test`: Query-document pairs for retrieval evaluation

**Columns:**
- `first_ipcr3`
- `q`
- `problem`
- `full_text`
- `first_ipcr3_count`

### Data Sample

Below is a 5-row preview of the test set:

```

### Evaluation Metrics

This task uses **NDCG@10** (Normalized Discounted Cumulative Gain at rank 10) as the primary metric.
NDCG measures ranking quality by discounting relevance scores by logarithmic position, normalized by the ideal ranking.

## Usage

### Load Dataset

```python
from datasets import load_dataset

# Load the dataset
dataset = load_dataset("datalyes/{task_name}")

# Access test split
test_data = dataset['test']

```

### Use with Sentence Transformers

```python
from sentence_transformers import SentenceTransformer

# Load a patent-specialized model
model = SentenceTransformer("datalyes/patembed-base")

# Encode patent texts
embeddings = model.encode(test_data['text'])
```

### Integrate with MTEB

This dataset is designed to be integrated with the MTEB (Massive Text Embedding Benchmark) framework. Integration with MTEB is in progress and will be available once the corresponding pull requests are accepted.

## Benchmark Context

This dataset is part of a larger benchmark suite:

| Benchmark Component | Description |
|-------------------|-------------|
| **PatenTEB** | 15 tasks covering retrieval, classification, paraphrase, clustering |
| **Test Data (Released)** | 319,320 examples across all 15 tasks |
| **Training/Validation Data** | 1.74 million examples (planned for future release) |
| **Total Dataset Size** | 2.06 million annotated instances |

**Note**: Currently, only the test split is publicly available. Training and validation data release is planned for a future date.

**All 15 Tasks (NEW to MTEB)**:
- 3 classification tasks: Bloom timing, NLI directionality, IPC3 classification
- 2 clustering tasks: IPC-based, Inventor-based  
- 8 retrieval tasks: 3 symmetric (IN/MIXED/OUT domain) + 5 asymmetric (fragment-to-full)
- 2 paraphrase tasks: Problem and solution paraphrase detection

**MTEB Integration**: Upcoming (PR in progress)
