PROFILE
Marcel Yeonghyeon Ko
In June 2025, contributed to the opensearch-project/neural-search repository by developing the FixedCharLengthChunker, a component designed for character-based text chunking with configurable segment size and overlap. This work involved enhancing the TextChunkingProcessor and ChunkerFactory to support the new chunker, updating statistical tracking, and implementing a comprehensive suite of integration and unit tests to ensure reliability. The solution, built using Java and Groovy, enables more predictable segmentation of long documents, improving downstream NLP pipeline performance and search quality. The approach emphasized backend development, robust test coverage, and clear commit traceability, with a focus on maintainable text processing architecture.
