SpanMarker for Named Entity Recognition
The SpanMarker project introduces an innovative framework designed to amplify the capabilities of Named Entity Recognition (NER) models. By utilizing well-known encoders such as BERT, RoBERTa, and ELECTRA, SpanMarker offers an effective and accessible solution for various natural language processing tasks.
Key Features
SpanMarker stands on the shoulders of the popular 🤗 Transformers library, inheriting its extensive capabilities. This includes effortless loading and saving of models, hyperparameter optimization, integrated logging, and much more. Built atop this robust foundation, SpanMarker simplifies the process of model training and deployment, making it accessible even for those with limited technical expertise.
Origin and Development
The development of SpanMarker is inspired by the insights from the PL-Marker paper. SpanMarker distinguishes itself with user-friendly features, ensuring compatibility right from the start with several common encoders, including bert-base-cased and roberta-large. It also supports different dataset annotation schemes such as IOB, IOB2, BIOES, and BILOU.
Integration and Testing
In collaboration with the Hugging Face Hub and Inference API, SpanMarker demonstrates seamless integration allowing users to experiment and prototype rapidly. Users have the facility to test models directly on the Hugging Face Hub using a user-friendly widget available on the model page. Additionally, SpanMarker models offer free APIs for testing and deployment, boosting productivity and innovation.
Pre-trained Models
SpanMarker includes a rich array of pre-trained models. Noteworthy examples encompass:
- FewNERD Models achieving impressive F1 scores which cater to multilingual needs.
- OntoNotes v5.0 and CoNLL03 models, which show state-of-the-art performance.
- CoNLL++ and MultiNERD models, offering exceptional multilingual capabilities and document-level context analysis.
Each model is accompanied by training scripts and API widgets, providing an easy playground for researchers and developers.
Installation and Usage
The SpanMarker library can be installed via pip:
pip install span_marker
Users can refer to the Getting Started guide for an introductory walkthrough. The documentation provides comprehensive outline on how to configure models and execute training scripts successfully.
