The Dice Coefficient - String Matching Algorithm

Performance:

• Optimized for Efficiency:
  • Uses lightweight string comparison techniques to ensure fast calculations even on larger datasets.
  • Efficient memory management to avoid performance degradation in complex workflows.

UiPath Activity Specifications:

• Inputs:
  • String1 (String): First input string to compare.
  • String2 (String): Second input string to compare.
• Outputs:
  • SimilarityScore (Double): Dice coefficient score ranging between 0 (no similarity) and 1 (exact match).

Bug Fixes:

• None (First Release)

Known Issues:

• High Memory Usage for Large Strings:
  • Handling very large strings may result in increased memory usage. Future versions will optimize the tokenization process for large text data.

Future Improvements:

1. Weighted Dice Coefficient:
   • A weighted version of the algorithm to address cases where certain tokens/characters are more important in the comparison.
2. Advanced Text Normalization:
   • Add customizable normalization options like handling special characters, stemming, or lemmatization.
3. Parallel Processing:
   • Enable multithreaded processing in UiPath workflows to handle multiple comparisons simultaneously for faster execution.
