Overview
dslim/bert-base-NER is a BERT-base model fine-tuned for Named Entity Recognition on the CoNLL-2003 English dataset, achieving F1 91.3 on the test set. It identifies four entity types: PER (persons), ORG (organizations), LOC (locations), and MISC (miscellaneous named entities).
Deploy as a SageMaker endpoint for in-VPC PII detection, document tagging, and entity extraction at scale. Unlike Amazon Comprehend, this endpoint has no per-character pricing -- you pay a flat $0.08/hr regardless of how many documents you process, making it cost-effective for high-volume extraction over internal document stores.
The endpoint returns character-offset entity spans with entity type and confidence score. Span merging for multi-token entities is handled in the endpoint's inference.py using HuggingFace's aggregation_strategy="simple" to ensure clean entity boundaries.
Primary use cases: PII detection and redaction before storing customer documents, entity-based document indexing for search, contract analysis (extract party names, organizations, locations), compliance screening, and any pipeline that needs to identify and tag named entities at scale without sending data to external services.
Highlights
- F1 91.3 on CoNLL-2003 -- production-grade NER for PER, ORG, LOC, MISC entities, all inference in your AWS VPC
- No per-character pricing unlike Comprehend -- flat $0.08/hr whether you process 100 or 100,000 documents per hour
- Returns character-offset entity spans with confidence scores -- ready for PII redaction, document tagging, and contract analysis
