Animation for the anagram "Listen = Silent" An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. [1] For example, the word anagram itself can be rearranged into the phrase "nag a ram". The original word or phrase is known as the subject of the ...
An anatree [1] is a data structure designed to solve anagrams. Solving an anagram is the problem of finding a word from a given list of letters. These problems are commonly encountered in word games like Scrabble or in newspaper crossword puzzles. The problem for the wordwheel also has the condition that the central letter appear in all the ...
This leads to a requirement to perform Unicode normalization before comparing two Unicode strings and to carefully design encoding converters to correctly map all of the valid ways to represent a character in Unicode to a legacy encoding to avoid data loss. [1]
The similarity of two strings and is determined by this formula: twice the number of matching characters divided by the total number of characters of both strings. The matching characters are defined as some longest common substring [3] plus recursively the number of matching characters in the non-matching regions on both sides of the longest common substring: [2] [4]
The specific similarity theory states that learning occurs by encoding each letter string in the learning phase as a whole. Grammaticality judgments in the test phase are made by comparing novel letter string to the ones already in memory. The more similar a string is to the remembered strings, the more grammatical it is reported to be. [26]
The most widely known string metric is a rudimentary one called the Levenshtein distance (also known as edit distance). [2] 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.
An anadrome is therefore a special type of anagram. The English language is replete with such words. The English language is replete with such words. The word anadrome comes from Greek anádromos ( ἀνάδρομος ), "running backward", and can be compared to palíndromos ( παλίνδρομος ), "running back again" (whence palindrome ).
In computational linguistics and computer science, edit distance is a string metric, i.e. a way of quantifying how dissimilar two strings (e.g., words) are to one another, that is measured by counting the minimum number of operations required to transform one string into the other.
