Semi-automated annotation techniques
Semi-automated annotation combines machine learning with human verification to speed up the annotation process. Here’s a simple example using spaCy:
import spacy
nlp = spacy.load("en_core_web_sm")
def semi_automated_ner(text):
doc = nlp(text)
return [(ent.start_char, ent.end_char, ent.label_)
for ent in doc.ents]
text = "Apple Inc. was founded by Steve Jobs in Cupertino."
auto_annotations = semi_automated_ner(text)
print(f"Auto-generated annotations: {auto_annotations}")
# Human annotator would then verify and correct these annotations This code uses a pre-trained spaCy model to generate initial NER annotations, which can then be verified and corrected by human annotators.
Next, we explore a couple of strategies for scaling annotation workflows to handle large-scale language datasets.
