Untitled

This action searches for a given string inside a list of strings by estimating their similarity using configurable algorithms.

Obs: Only the strings with a similarity score greater than or equal to the specified threshold are returned.

Inputs & Outputs

• [ I ] List of strings to search into: Collection of strings in which the search will be performed.
• [ I ] Similarity algorithm: Drop-down list of available string similarity algorithms.
  • Options include: BlockDistance, CosineSimilarity, JaccardSimilarity, DiceSimilarity, Jaro, JaroWinkler, Levenstein, MongeElkan, NeedlemanWunch, SmithWaterman, SmithWatermanGotoh, and others.
  • Default: SmithWaterman
• [ I ] Similarity threshold [0-1]: Decimal number between 0 and 1. Strings with similarity below this value will not be included in the results.
  • Default: 0.85
• [ I ] String to search for: The string that will be compared against the list items.
• [ I ] Limit number of search results: Integer. Specifies how many top results to return.
  • Default: 100
  • If set to 0 ➜ returns all results.
• [ O ] Output list of search results: List of strings from the input that are most similar to the searched string.

Example Usage

• Drag Search by String Similarity onto the canvas.

• Declare some variables to be used with the action:
  • myList → ["apple", "applesauce", "banana", "grape"]
  • mySearch → "apple"
  • myThreshold → 0.8
  • myAlgorithm → JaroWinkler

• Assign the variables in the configuration:
  • List of strings to search into = myList
  • String to search for = mySearch
  • Similarity threshold = myThreshold
  • Similarity algorithm = myAlgorithm
  • Limit number of search results = 5
  • Output list of search results → similarStrings
• Save & Run the process and then Check Instance to see the output.

Expected result: similarStrings = ["apple", "applesauce"]

Use Cases

• Finding the closest matches for a search term inside a catalog or dataset.
• Suggesting alternatives when user input is misspelled or partially correct.
• Performing fuzzy search operations in process automations.
