MElt is a freely available (LGPL) state-of-the-art sequence labeller that is meant to be trained on both an annotated corpus and an external lexicon. It was initially developed by Pascal Denis and Benoît Sagot. Recent evolutions have been carried out by Benoît Sagot. MElt allows for using multiclass Maximum-Entropy Markov models (MEMMs) or multiclass perceptrons (multitrons) as underlying statistical devices. Its output is in the Brown format (one sentence per line, each sentence being a space-separated sequence of annotated words in the word/tag format).
This repository provides a way to contain in a docker container the tool MElt for French Part of Speech tagging.
To build the image, run the following command :
sudo docker build -t melt -f Dockerfile .
To run a container :
sudo docker run --name melt -d -p 5000:5000 -it melt
The listening will be by default 5000.
To test your setup, you can try to POST data directly via CLI.
curl -H "Content-Type: application/json" \
-X POST \
-d '{"data":"Il fait beau dehors. Mais Paris est trop petit pour pouvoir en profiter, et surtout trop cher"}' \
http://localhost:5000/pos_and_tokenize
Or via the library requests :
r = requests.post('http://localhost:5000/pos_and_tokenize',
json={'data': "Il fait beau dehors. Mais Paris est trop petit pour pouvoir en profiter, et surtout trop cher"},
headers={'Content-Type':'application/json', 'charset': 'utf-8'})
print(r.content)You should get the output :
Il/CLS fait/V beau/ADJ dehors/ADV ./PONCT
Mais/CC Paris/NPP est/V trop/ADV petit/ADJ pour/P pouvoir/VINF en/CLO profiter/VINF ,/PONCT et/CC surtout/ADV trop/ADV cher/ADJ
To interact with the API, you need to POST your content in a JSON format.
