A necessary requirement for a string ''metric'' (e.g. in contrast to string matching) is fulfillment of the triangle inequality. For example the strings "Sam" and "Samuel" can be considered to be close. A string metric provides a number indicating an algorithm-specific indication of distance. The most widely known string metric is a rudimentary one called the Levenshtein Distance (also known as Edit Distance). It operates between two input strings, returning a number equivalent to the number of substitutions and deletions needed in order to transform one input string into another. Simplistic string metrics such as Levenshtein distance have expanded to include phonetic, token, grammatical and character-based methods of statistical comparisons. String metrics are used heavily in information integration and are currently used in areas including fraud detection, fingerprint analysis, plagiarism detection, ontology merging, DNA analysis, RNA analysis, image analysis, evidence-based machine learning, database data deduplication, data mining, Web interfaces, e.g. Ajax-style suggestions as you type, data integration, and semantic knowledge integration. ==List of string metrics== * Sørensen–Dice coefficient * Block distance or L1 distance or City block distance * Jaro–Winkler distance * Simple matching coefficient (SMC) * Jaccard similarity or Jaccard coefficient or Tanimoto coefficient * Most frequent k characters * Tversky index * Overlap coefficient * Variational distance * Hellinger distance or Bhattacharyya distance * Information radius (Jensen–Shannon divergence) * Skew divergence * Confusion probability * Tau metric, an approximation of the Kullback–Leibler divergence * Fellegi and Sunters metric (SFS) * Maximal matches * TFIDF distance metric 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「String metric」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
