Practical Programs for Processing Mixed Language Texts
Common challenges: Technical documents often contain a mix of languages, and traditional lexers have a high error rate.
prescription::
- Automatic detection mechanisms: Integration
from tokendagger.language import detect_spanModule recognizes text fragment language - hybrid processing mode: Enable the code snippet for
strict=FalseParameters retain their original format - Customized rules: By
add_special_regex(r'$[a-z]+')Adding Domain Specific Patterns
workflow::
- Pre-treatment phase: use of
text = normalize_mixed_content(raw_text)Harmonized coding format - Layering: first press
detect_paragraph_lang()Segmentation and then applying the corresponding language encoder separately - Post-processing consolidation: by
merge_tokens()Ensure that the original offsets are accurate - Validation result: check that special symbols (e.g. $variable) are correctly preserved
