### Dataset Summary

The Multi-LexSum dataset is a collection of 9,280 such legal case summaries. Multi-LexSum is distinct from other datasets in its **multiple target summaries, each at a different granularity** (ranging from one-sentence “extreme” summaries to multi-paragraph narrations of over five hundred words). It presents a challenging multi-document summarization task given **the long length of the source documents**, often exceeding two hundred pages per case. Unlike other summarization datasets that are (semi-)automatically curated, Multi-LexSum consists of **expert-authored summaries**: the experts—lawyers and law students—are trained to follow carefully created guidelines, and their work is reviewed by an additional expert to ensure quality.

### Data Fields

The dataset contains a list of instances (cases); each instance contains the following data: 

|         Field |                                                                      Description |
| ------------: | -------------------------------------------------------------------------------: |
|            id |                                                              `(str)` The case ID |
|       sources | `(List[str])` A list of strings for the text extracted from the source documents |
|  summary/long |                         `(str)` The long (multi-paragraph) summary for this case |
| summary/short |                `(Optional[str])` The short (one-paragraph) summary for this case |
|  summary/tiny |                  `(Optional[str])` The tiny (one-sentence) summary for this case |

Please check the exemplar usage below for loading the data: 

```python
from datasets import load_dataset

multi_lexsum = load_dataset("allenai/multi_lexsum", name="v20230518")
# Download multi_lexsum locally and load it as a Dataset object 

example = multi_lexsum["validation"][0] # The first instance of the dev set 
example["sources"] # A list of source document text for the case

for sum_len in ["long", "short", "tiny"]:
    print(example["summary/" + sum_len]) # Summaries of three lengths

  print(example['case_metadata']) # The corresponding metadata for a case in a dict 
```
