ADVANCED DATA QUALITY SOLUTIONS FOR GOOGLE SHEETS

A BRIEF LOOK AT YOUR DATA QUALITY PROBLEM

If you deal with merging multiple sources of data, data migration, exporting and importing data, etc. then you have undoubtedly had data quality issues in your work. According to this infographic by IBM, poor data quality costs the United States economy about $3.1 trillion every year. That easily translates to an average of $100 per database record for businesses in comparative economies, U.S inclusive.

Data quality issues might arise when data is merged from different sources. This can create duplicate records that lower productivity, increase budget costs, lower customer satisfaction and reduce labour efficiency. You might also face data quality issues while attempting to compare data sets that contain typos, spelling variations, punctuation marks and other related complexities.

These are just some of the data quality issues you can avoid or resolve by adding Flookup to your software stack. Flookup will help you to increase productivity, reduce your error rate and save money.

POPULAR FUZZY MATCHING ALGORITHMS

Fuzzy string matching (also called approximate or partial string matching) is a technique for comparing strings that might have a less than 100% match. There are different techniques that are applied by fuzzy matching algorithms and the most popular involve the use of wildcard characters (in combination with functions like VLOOKUP or INDEX/MATCH), word or phrase comparisons, regular expressions (RegEx/RegExp) and edit distance. Examples of such implementations include:

    • Levenshtein Distance: This algorithm calculates and returns the minimum number of single-character edits (i.e. insertions, deletions or substitutions) required to change one word into another.
    • Damerau–Levenshtein Distance: This algorithm is exactly like Levenshtein distance with one exception; it includes transpositions amongst its edits.
    • Jaro–Winkler Distance: The Jaro distance between two words is the minimum number of single-character transpositions required to change one word into the other.
    • n-gram: This is a contiguous sequence of n items from a given sequence of text or speech. The items can be phonemes, syllables, letters, words or base pairs according to the application.
    • Soundex: This is a phonetic algorithm for indexing names by sound, as pronounced in English. The goal is for homophones to be encoded to the same representation so that they can be matched despite minor differences in spelling.
