# Inspec Benchmark Dataset for Keyphrase Generation

## About

Inspec is a dataset for benchmarking keyphrase extraction and generation models.
The dataset is composed of 2,000 abstracts of scientific papers collected from the [Inspec database](https://www.theiet.org/resources/inspec/).
Keyphrases were annotated by professional indexers in an uncontrolled setting, that is, they are not limited to entries in a thesaurus.
Details about the inspec dataset can be found in the original paper:

## Content

The dataset is divided into the following three splits:

| Split      | # documents |
| :--------- |-----------: |
| Train      | 1,000       |
| Test       | 500         | 
| Validation | 500         | 

The following data fields are available :

- **id**: unique identifier of the document.
- **title**: title of the document.
- **abstract**: abstract of the document.
- **keyphrases**: list of reference keyphrases (uncontrolled).
