  • Approximate dictionary matching is a classic string matching problem, with applications in, e.g., online catalogs, geolocation (mapping possibly misspelled location description to geocoordinates), web searchers, etc. We present a surprisingly simple solution, based on the Dirichlet principle, for matching a keyword with few mismatches and experimentally show that it offers competitive space-time tradeoffs. Our implementation in the C++ language is focused mostly on data compaction, which is… CONTINUE READING
