Soundex

  • Soundex is the classic algorithm, provided by most databases (Oracle, Microsoft, …)

  • How useful is soundex?

  • Not very – for information retrieval

  • Okay for “high recall” tasks (e.g., Interpol), though biased to names of certain nationalities

  • Zobel and Dart (1996) show that other algorithms for phonetic matching perform much better in the context of IR
