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.
