In some implementations, a target bitmap is produced for the target character string and a target bitmap weight is calculated. A candidate bitmap and a candidate bitmap weight associated with a candidate character string is obtained. In response to determining that the candidate bitmap weight differs from the target bitmap weight by less than a first threshold value, an exclusive OR operation is performed between the target bitmap and the candidate bitmap. In response to determining that number of ones in the result of the exclusive OR is less than a second threshold value, the candidate character string is included in a character set that includes one or more character strings that are close to the target character string."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Character string distance calculation method and device","description":"Techniques for determining character string differences between a target character string and one or more candidate character strings are provided.
