Misspelling identification in domain names

A method comprising:

• aggregating, by a server comprising a custom-designed special purpose computing device coupled to a network and including at least one processor executing instructions comprising a specific device logic within a memory, a plurality of search sessions including a search session for a domain name determined by the server to be unavailable, the search session being identified by a unique search session identifier and comprising a plurality of consecutive queries by a user during the search session;
• identifying, by the server, within the search session, a longest common string between each of the plurality of consecutive queries;
• identifying, by the server, an interchangeable character string for the longest common string by:
• searching at least one electronic dictionary database for the longest common string;
• and
• responsive to a determination that the longest common string is not in the at least one electronic dictionary identify a misspelling type as a typo misspell or a phonetic spin misspell according to a character analysis and a phonetic similarity respectively, wherein if the misspelling type is not the phonetic spin, it is the typo misspell;
• generating, by the server, for each of the plurality of consecutive queries in the search session subsequent to an initial domain name search query, a unique data record within a misspelled token database comprising:
• the unique search session identifier;
• the longest common string;
• the interchangeable character string;
• a frequency of use that the interchangeable character string and the longest common string exist within the plurality of search sessions;
• and
• a modification type describing the relationship between the interchangeable character string and the longest common string as the typo misspell or the phonetic misspell;
• identifying, by the server, within a search string, a token;
• executing, by the server, a query selecting, from the misspelled token database, a misspelled token matching the token and comprising the longest common string;
• generating, by the server, a corrected search string replacing the token with a corrected token comprising the interchangeable character string stored in association with the misspelled token in the misspelled token database;
• and
• responsive to a determination, according to a language model determining the frequency of use, that the corrected search string has a higher probability of representing an intent of the user, generating, by the server computer, at least one alternative available domain name candidate including the corrected token.
