Word Sense Linking: Disambiguating Outside the Sandbox

Conference Paper Hugging Face Collection GitHub

Model Description

The Word Sense Linking model is designed to identify and disambiguate spans of text to their most suitable senses from a reference inventory. The annotations are provided as sense keys from WordNet, a large lexical database of English.

Installation

Installation from PyPI:

git clone https://github.com/Babelscape/WSL
cd WSL
pip install -r requirements.txt

Usage

WSL is composed of two main components: a retriever and a reader. The retriever is responsible for retrieving relevant senses from a senses inventory (e.g WordNet), while the reader is responsible for extracting spans from the input text and link them to the retrieved documents. WSL can be used with the from_pretrained method to load a pre-trained pipeline.

from wsl import WSL
from wsl.inference.data.objects import WSLOutput

wsl_model = WSL.from_pretrained("Babelscape/wsl-base")
relik_out: WSLOutput = wsl_model("Bus drivers drive busses for a living.")
WSLOutput(
text='Bus drivers drive busses for a living.',
tokens=['Bus', 'drivers', 'drive', 'busses', 'for', 'a', 'living', '.'],
id=0,
spans=[
    Span(start=0, end=11, label='bus driver: someone who drives a bus', text='Bus drivers'),
    Span(start=12, end=17, label='drive: operate or control a vehicle', text='drive'),
    Span(start=18, end=24, label='bus: a vehicle carrying many passengers; used for public transport', text='busses'),
    Span(start=31, end=37, label='living: the financial means whereby one lives', text='living')
],
candidates=Candidates(
    candidates=[
                {"text": "bus driver: someone who drives a bus", "id": "bus_driver%1:18:00::", "metadata": {}},
                {"text": "driver: the operator of a motor vehicle", "id": "driver%1:18:00::", "metadata": {}},
                {"text": "driver: someone who drives animals that pull a vehicle", "id": "driver%1:18:02::", "metadata": {}},
                {"text": "bus: a vehicle carrying many passengers; used for public transport", "id": "bus%1:06:00::", "metadata": {}},
                {"text": "living: the financial means whereby one lives", "id": "living%1:26:00::", "metadata": {}}
    ]
