# bart-large-finetuned-filtered-spotify-podcast-summ |
|
|
|
This model is a fine-tuned version of [facebook/bart-large-cnn](https://huggingface.co/facebook/bart-large-cnn) on on the [Spotify Podcast Dataset](https://arxiv.org/abs/2004.04270). Take a look to the [github repository](https://github.com/TheOnesThatWereAbroad/PodcastSummarization) of this project. |
|
|
|
It achieves the following results during training: |
|
- Train Loss: 2.2967 |
|
- Validation Loss: 2.8316 |
|
- Epoch: 2 |
|
|
|
## Intended uses & limitations |
|
|
|
This model is intended to be used for automatic podcast summarisation. Given the podcast transcript in input, the objective is to provide a short text summary that a user might read when deciding whether to listen to a podcast. The summary should accurately convey the content of the podcast, be human-readable, and be short enough to be quickly read on a smartphone screen. |
|
|
|
## Training and evaluation data |
|
In our solution, an extractive module is developed to select salient chunks from the transcript, which serve as the input to an abstractive summarizer. |
|
An extensive pre-processing on the creator-provided descriptions is performed selecting a subset of the corpus that is suitable for the training supervised model. |
|
|
|
We split the filtered dataset into train/dev sets of 69,336/7,705 episodes. |
|
The test set consists of 1,027 episodes. Only 1025 have been used because two of them did not contain an episode description. |
|
|
|
|
|
## How to use |
|
|
|
The model can be used for the summarization as follows: |
|
|
|
```python |
|
from transformers import pipeline |
|
summarizer = pipeline("summarization", model="gmurro/bart-large-finetuned-filtered-spotify-podcast-summ", tokenizer="gmurro/bart-large-finetuned-filtered-spotify-podcast-summ") |
|
summary = summarizer(podcast_transcript, min_length=39, max_length=250) |
|
print(summary[0]['summary_text']) |
|
``` |
|
|
|
