argrelextrema, which helps in determining local maxima in data, essential for calculating optimal thresholds. - Joblib: Enhances performance through parallel processing.
- Fuzzywuzzy: Facilitates fuzzy string comparisons, pivotal in finding URL similarities.
- Difflib and Levenshtein: Provides various algorithms for meticulous string matching and comparison.
The script orchestrates the following workflow:
- File Upload and Size Validation: Allows users to upload Excel files containing URLs, validating against a predefined file size limit.
- Data Loading and Cleaning: Uploaded files are processed into Pandas DataFrames. URLs undergo a cleaning and standardization process for uniform analysis.
- Algorithm Selection: Users select from several string matching algorithms, including:
- Fuzzy Matching: For approximate string comparisons.
- Levenshtein Distance: Measures the difference between sequences.
- Jaccard Similarity: Assesses the similarity and diversity of sample sets.
- Hamming Distance: Calculates the distance between string sequences.
- Ratcliff/Obershelp: Provides a ratio of the sequences' similarity.
- Tversky Index: A generalized form of set similarity.
- Similarity Calculation and Threshold Determination:
- Parallel processing is used for swift calculation of similarity scores.
- The "elbow" method identifies the optimal threshold for similarity.
- Agreement Counting and DataFrame Update:
- Counts algorithm agreement on URL redirects, updating the DataFrame with these insights.
- This crucial step highlights the most consistent redirect URL across different algorithms.
- Result Presentation and Download:
- Displays the final merged DataFrame with suggested redirects and algorithm agreements.
- Provides an option to download this data as an Excel file.
