## Dataset Description

- **Homepage: https://trusthlt.org/lacour**
- **Repository: https://github.com/trusthlt/lacour-corpus**
- **Paper: tbd**

### Dataset Summary

This dataset contains transcribed court hearings sourced from official hearings of the __European Court of Human Rights__ ([https://www.echr.coe.int/webcasts-of-hearings](https://www.echr.coe.int/webcasts-of-hearings)). The hearings are 154 selected webcasts (videos) from 2012-2022 in their original language (no interpretation). With manual annotation for language labels and automatic processing of the extracted audio with [pyannote](https://huggingface.co/pyannote/speaker-diarization) and [whisper-large-v2](https://huggingface.co/openai/whisper-large-v2), the resulting dataset contains 4000 speaker turns and 88920 individual lines. The dataset contains two subsets, the transcripts and the metadata with linked documents. The transcripts are additionally available as .txt or .xml.

### Languages

The largest amounts in the transcripts are:

English, French

A smaller portion also contains the following languages:

Russian, Spanish, Croatian, Italian, Portuguese, Turkish, Polish, Lithuanian, German, Ukrainian, Hungarian, Dutch, Albanian, Romanian, Serbian

The collected metadata is:

English

## Dataset Structure

### Data Instances

Each instance in transcripts represents an entire segment of a transcript, similar to a conversation turn in a dialog.  

```
{
 'id': 0,
 'webcast_id': '1021112_29112017',
 'segment_id': 0,
 'speaker_name': 'UNK',

   'end': [13.359999656677246],
   'language': ['fr'],
   'text': ['La Cour!']
  }
}
```

Each instance in documents represents a information on a document in hudoc associated with a hearing and the metadata associated with a hearing. The actual document is linked and can also be found in [hudoc](https://hudoc.echr.coe.int) with the case_id. Note: `hearing_type` states the type of the hearing, `type` states the type of the document. If the hearing is a "Grand Chamber hearing", the "CHAMBER" document refers to a different hearing.

## Dataset Creation

### Curation Rationale

This datasets provides partly corrected transcribed webcasts to enable the processing of hearings in legal NLP. No specific task is given.

### Source Data

#### Data Collection

The data was collected by transcribing the publicly available [webcasts of the ECHR](https://www.echr.coe.int/webcasts-of-hearings) with the help of [pyannote](https://huggingface.co/pyannote/speaker-diarization) and [whisper-large-v2](https://huggingface.co/openai/whisper-large-v2). The documents were sourced from the [ECHR hudoc database](https://hudoc.echr.coe.int).

#### Who are the source producers?

Participants in hearings before the ECHR for the audio and video material. Employees and judges of the ECHR for the documents.

### Annotations

#### Annotation process

**language identification** Spoken languages were manually identified by research assistants. Disagreements were discussed to achieve the final language label.

**transcript correction** All parts spoken by Judge or Judge President are corrected for the languages English and French by research assistants with a high proficiency in the respective language.

#### Personal and Sensitive Information

The dataset contains names of judges and other participants in the hearings. Due to those names being available in the public court material, we did not remove them. The machine-generated transcripts may also contain names, which were neither checked nor removed. In case of sensitive information, we rely on the provided material to provide protection (occasionally bleeping out names which should not have been mentioned in webcasts, appropriate anonymization in the documents).


## Additional Information

Download the transcripts and linked documents:

```
from datasets import load_dataset

lacour_transcripts = load_dataset("TrustHLT/LaCour", "transcripts") # default config
lacour_documents = load_dataset("TrustHLT/LaCour", "documents")

```

Formatted versions of the transcripts in .txt and .xml and more information on the collection and creation can be found on [github](https://github.com/trusthlt/lacour-corpus).
