+# Dataset Card for AbsenceBench
+
+AbsenceBench covers three distinct domains:
+- Poetry (realistic)
+- Numerical sequences (synthetic)
+- GitHub pull requests (realistic)
+
+There are 4302 instances in total, with an average context length of 5K tokens.
+
+## Data Structure
+Each domain contains the following features:
+- `original_context`: `string`
+- `modified_context`: `string`
+- `omitted_context`: `List[string]`
+- `omitted_index`: `List[int]` 
+- `metadata`: `Dict` Extra information regarding the dataset generation
+
+### Data Split
+Currently we provide only the `validation` split. Since all instances of AbsenceBench natually come up with labeled answers according to the task setting, we will not be able to provide an unlabeled `test` split.
+
+## Dataset Construction
+We provide the source data for generating the poetry domain, originally from the [Gutenberg Poetry Corpus](https://github.com/aparrish/gutenberg-poetry-corpus) in the `poetry_raw` subset.
+Please refer to this [repo](https://github.com/harvey-fin/absence-bench) for scripts and more information.
