Known weaknesses
Each one links to the public issue, changelog or docs page it came from, where we have one.
- 01
Limited language support beyond English
The Stanford English Tokenizer is primarily optimized for English and may not perform as well with other languages without significant customization.
- 02
Performance overhead due to Java runtime
As a Java-based tool, it can suffer from higher memory consumption and slower startup times compared to native or more lightweight solutions.
- 03
Documentation is not comprehensive for advanced use cases
The documentation focuses on basic usage but lacks detailed guides for complex configurations and customization, which can be challenging for developers needing advanced features.
