🚀 Quick Start

ReLiK is a lightweight and fast model for Entity Linking and Relation Extraction. It is composed of two main components: a retriever and a reader. The retriever is responsible for retrieving relevant documents from a large collection, while the reader is responsible for extracting entities and relations from the retrieved documents. ReLiK can be used with the from_pretrained method to load a pre-trained pipeline.

Here is an example of how to use ReLiK for Relation Extraction:

from relik import Relik
from relik.inference.data.objects import RelikOutput

relik = Relik.from_pretrained("sapienzanlp/relik-relation-extraction-nyt-large")
relik_out: RelikOutput = relik("Michael Jordan was one of the best players in the NBA.")

RelikOutput(
  text='Michael Jordan was one of the best players in the NBA.', 
  tokens=Michael Jordan was one of the best players in the NBA., 
  id=0, 
  spans=[
    Span(start=0, end=14, label='--NME--', text='Michael Jordan'), 
    Span(start=50, end=53, label='--NME--', text='NBA')
  ], 
  triplets=[
    Triplets(
      subject=Span(start=0, end=14, label='--NME--', text='Michael Jordan'), 
      label='company', 
      object=Span(start=50, end=53, label='--NME--', text='NBA'), 
      confidence=1.0
      )
  ], 
  candidates=Candidates(
    span=[], 
    triplet=[
              [
                [
                  {"text": "company", "id": 4, "metadata": {"definition": "company of this person"}}, 
                  {"text": "nationality", "id": 10, "metadata": {"definition": "nationality of this person or entity"}}, 
                  {"text": "child", "id": 17, "metadata": {"definition": "child of this person"}}, 
                  {"text": "founded by", "id": 0, "metadata": {"definition": "founder or co-founder of this organization, religion or place"}}, 
                  {"text": "residence", "id": 18, "metadata": {"definition": "place where this person has lived"}},
                  ...
              ]
          ]
      ]
  ),
)
