spark-nlp
A state-of-the-art Natural Language Processing library built on Apache Spark, offering 100,000+ pretrained models and pipelines in 200+ languages.
What is spark-nlp?
Spark NLP is a state-of-the-art Natural Language Processing library built on top of Apache Spark. It provides performant and accurate NLP annotations for machine learning pipelines that scale easily in distributed environments, solving the problem of applying advanced NLP tasks like named entity recognition, sentiment analysis, and text generation to large datasets. It offers over 100,000 pretrained pipelines and models in more than 200 languages.
Data engineers, data scientists, and ML engineers working with large-scale NLP workloads in distributed computing environments, particularly those already using Apache Spark for big data processing. It also targets enterprises needing production-ready, scalable NLP solutions across Python, R, and JVM ecosystems.
Developers choose Spark NLP because it is the only open-source NLP library in production that offers state-of-the-art transformers like BERT, GPT, and Llama to both Python/R and JVM ecosystems at scale, with seamless integration into existing Apache Spark workflows. Its extensive model library, multi-framework import support, and cross-platform compatibility provide enterprise-grade NLP capabilities that are both performant and easy to deploy.
Overview
State of the Art Natural Language Processing
Use Cases
Best For
- Processing large-scale text datasets with distributed NLP pipelines in Apache Spark environments.
- Deploying state-of-the-art transformer models (like BERT, Llama-2, Whisper) in production across Python, Java, Scala, and Kotlin applications.
- Implementing multilingual NLP tasks such as machine translation, named entity recognition, or sentiment analysis across 200+ languages.
- Integrating models from various frameworks like TensorFlow, ONNX, OpenVINO, and Llama.cpp into unified Spark workflows.
- Building enterprise NLP applications that require high performance and scalability on CPU, GPU, AArch64, or Apple Silicon architectures.
- Conducting end-to-end NLP tasks including text preprocessing, classification, question answering, summarization, and text generation within a single library.
Not Ideal For
- Real-time applications requiring low-latency inference, due to Spark's batch processing overhead.
- Small-scale projects or prototypes where managing Apache Spark clusters is unnecessary complexity.
- Teams exclusively using non-JVM languages like JavaScript or Go without integration plans.
- Environments with limited computational resources where Spark's memory and setup demands are prohibitive.
Pros & Cons
Pros
Offers over 100,000 pretrained pipelines and models in more than 200 languages, covering diverse NLP tasks without custom training.
Built directly on Apache Spark, enabling seamless distribution of NLP workflows across clusters for big data processing.
Supports importing models from TensorFlow, ONNX, OpenVINO, and Llama.cpp, providing flexibility in model sourcing and deployment.
Provides native APIs for Python, R, Java, Scala, and Kotlin, making it accessible across different tech stacks in enterprises.
Cons
M1/M2 and AArch64 support is labeled as experimental in the README, with limited community backing and potential compatibility issues.
Requires managing Java, Apache Spark, and library versions, which can be cumbersome for teams not already in the Spark ecosystem.
Inherits Spark's batch processing nature, making it less suitable for real-time or streaming NLP compared to lighter libraries.
