# TALN-Archives Benchmark Dataset for Keyphrase Generation

## About

TALN-Archives is a dataset for benchmarking keyphrase extraction and generation models.
The dataset is composed of 1207 abstracts of scientific papers in French collected from the [TALN Archives](http://talnarchives.atala.org/). 
Keyphrases were annotated by authors in an uncontrolled setting (that is, not limited to thesaurus entries).
English translations of title/abstract/keyphrases are also available for a subset of the documents, allowing to experiment with cross-lingual / multilingual keyphrase generation.
Details about the dataset can be found in the original paper [(Boudin, 2013)][boudin-2013].

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` (`fr_core_news_sm` model) with a special rule to avoid splitting words with hyphens (e.g. graph-based is kept as one token).
Stemming (Snowball stemmer implementation for french 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 contains the following test split:

| Split      | # documents | #words | # keyphrases | % Present | % Reordered | % Mixed | % Unseen |
| :--------- | ----------: | -----: | -----------: | --------: | ----------: | ------: | -------: |
| Test       | 1207        | -  |  -        | -     | -        | -    | -     |

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.
- **prmu**: list of <u>P</u>resent-<u>R</u>eordered-<u>M</u>ixed-<u>U</u>nseen categories for reference keyphrases.
- **translation**: translations of title, abstract and keyphrases in English if available.
