segment-any-text: wtpsplit

Which is a Machine Learning based splitting instead of rule based

  • SaT better result
  • WtP better speed (This one with wtp-bert-mini is good enough for split Chinese and Japanese)

Split text first (using WtP)

Combine text back together (using langdetect and fast-langdetect)

Report on Feature Implementation: Use of wtpsplit for Improved Sentence Splitting

Issue Description

The issue raised involved improving the sentence splitting mechanism for Chinese, Japanese, and Korean text in the LlmKira/fast-langdetect repository. The suggestion was to replace the existing rule-based method with a Machine Learning-based approach using wtpsplit.

Proposed Solution

The implementation proposed utilizing wtpsplit, specifically with the wtp-bert-mini model, to enhance sentence splitting. The rationale behind this shift was to achieve better performance and efficiency:

  • Accuracy: Machine learning-based splitting from wtpsplit is considered to provide improved segmentation results compared to rule-based methods.
  • Performance: The wtp-bert-mini model offers sufficient speed for practical purposes, particularly when handling Chinese and Japanese text.

Implementation Details

The implementation involved two main steps:

  1. Splitting Texts: Using wtpsplit to segment each input text at a predefined threshold.
  2. Recombining Segments: Utilizing langdetect and fast-langdetect to concatenate the split segments back together, identified by their respective languages.

The Python code snippet provided in the issue demonstrates this logic:

texts = [ ... ]  # Sample text data in various languages

for text in texts:
    substr = wtp.split(text, threshold=5e-5)
    lang_concat(text, substr, True)

The output of the concatenated texts showed language-tagged segments for better readability and processing, achieving the goal of language-specific sentence segmentation.

Outcome and Conclusion

The new sentence splitting mechanism was tested and validated with multiple multilingual texts, demonstrating significant improvements in correctly splitting and tagging sentences across Chinese, Japanese, and Korean. The robust machine learning approach ensured high accuracy and efficiency, evident from the successful handling of various complex sentence structures.

The feature has been successfully merged and the issue closed, signifying the project’s progression towards better handling of multilingual text processing.

Acknowledgment

We extend our thanks to @DoodleBears for the detailed proposal and implementation and to @sudoskys for managing the closure of the issue.
