# 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, not limited to thesaurus entries). |
|
Details about the inspec dataset can be found in the original paper [(Hulth, 2003)][hulth-2003]. |
|
|
|
|
|
Reference (indexer-assigned) keyphrases are also categorized under the PRMU (<u>P</u>resent-<u>R</u>eordered-<u>M</u>ixed-<u>U</u>nseen) scheme as proposed in [(Boudin and Gallina, 2021)][boudin-2021]. |
|
|
|
Text pre-processing (tokenization) is carried out using `spacy` (`en_core_web_sm` model) with a special rule to avoid splitting words with hyphens (e.g. graph-based is kept as one token). |
|
Stemming (Porter's stemmer implementation provided in `nltk`) is applied before reference keyphrases are matched against the source text. |
|
Details about the process can be found in `prmu.py`. |
|

## Content and statistics |
|
|
|
The dataset is divided into the following three splits: |
|
|
|
| Split | # documents | #words | # keyphrases | % Present | % Reordered | % Mixed | % Unseen | |
