Contributed to the open source library Spark NLP and its licensed counterpart Spark NLP for Healthcare. Spark NLP is an open-source text processing library for advanced natural language processing for the Python, Java and Scala programming languages. The library is built on top of Apache Spark and its Spark ML library.Implemented the Byte-Pair Encoding (BPE) tokenization algorithm in Scala on top of Sparks MLlib to enable the usage of language transformers that require that kind of tokenization (for example RoBERTa, DistilBERT).Updated customer facing documentation of the Scala API with extended explanations and examples, to enable a smooth user experience of the library.
