==MD Keyboard==
===Specifics===
An algorithm developed by Melissa Data which counts keyboarding mis-hits.

===Summary===
This is a typographical matching algorithm which counts keyboarding mis-hits with a weighted penalty based on the distance of the mis-hit and assigns a percentage of similarity between the compared strings. Thus two records with c > v or v > b typos are more likely to have an actual duplicate.

===Returns===
Percentage of similarity

===Example Matchcode Component===
:[[File:MCO_Algorithm_MDKeyboard.png|link=]]

===Example Data===
{{ExampleDataTableV1|STRING1|STRING2|RESULT
|AdditionalRows=
{{EDTRow|White|Johnson|Jhnsn|Unique}}
{{EDTRow|White|Neumon|Pneumon|Match Found}}
{{EDTRow|Green|Hteberynost|Theverymost|Match Found}}
{{EDTRow|Green|Covert|Coberh|Match Found}}
}}

{{MatchcodePerformance

}}

===Recommended Usage===
Hybrid deduper, where a single incoming record can quickly be evaluated independently against each record in an existing large master database.

Batch processes where MDKEY is set on a single non-first matchcode component.

Databases where data entry is created real-time from call center or other inputs where keyboard mishits are more likely.

===Not Recommended For===
Databases where the number of errors with relation to the string length result is a small number of common substrings.

===Do Not Use With===
UTF-8 data. This algorithm was ported to MatchUp with the assumption that a character equals one byte, and therefore results may not be accurate if the data contains multi-byte characters.
