*New* You can create Mappings in a Code Map automatically as follows:

  • ...select the Auto Map tab. The Auto Map page is displayed:

  • Choose the Auto Map method you want to use. The different methods are as follows:
Algorithm Description
Source Code to Target Code A mapping is created for every Source Code that matches a Target Code e.g. Source Code=ABC maps to Target Code=ABC
Source Meaning to Target Meaning A mapping is created for every Source Meaning that matches a Target Meaning e.g. Source (43, Burglary) maps to Target (AQR, Burglary)
Source Code to Target Meaning A mapping is created for every Source Code that matches a Target Meaning e.g. Source (Green, Green) maps to Target (23, Green)
Source Meaning to Target Code A mapping is created for every Source Code where its Meaning matches a Target Code e.g. Source (12, FORD) maps to Target (FORD, FORD MOTORS)
Map by example on start of Source Code An existing mapping is copied for every Source Code that starts with the source code of the existing mapping e.g. if an existing mapping exists of Source (ABC, Murder) to Target (4367, MURDER) then further mappings to Target Code=4367 would be created for every Source Code that starts with ABC e.g. (ABCD, Murder of child), (ABCF, Racially motivated murder), (ABCG, Attempted murder)
Map by example on start of Source Meaning An existing mapping is copied for every Source Meaning that starts with the source meaning of the existing mapping e.g. if an existing mapping exists of Source (78, FORD) to Target (3214, FORD MOTORS) then further mappings to Target Code=3214 would be created for every Source Meaning that starts with FORD e.g (765, FORD MONDEO), (743, FORD PREFECT), (788, FORD FIESTA) etc
Fuzzy Term Match Source Code to Target Code A mapping is created for every Source Code where it nearly matches a Target Code. Only use this if your code list has codes that are Free Format (*) where fuzzy matching would be appropriate. It is unlikely to give useful results if your codes really are proper codes such as 1, 2, A4B etc. Options are described here.
Fuzzy Term Match Source Meaning to Target Meaning A mapping is created for every Source Meaning where it nearly matches a Target Meaning. This is the best option for most fuzzy matching jobs. Options are described here.
Fuzzy Sentence Match Source Code to Target Code A mapping is created for every Source Code where it nearly matches a Target Code. Only use this if your source and target code lists have codes that are Free Format (*) where fuzzy matching would be appropriate. It will give wrong results if your codes are not sentences. Options are described here.
Fuzzy Sentence Match Source Meaning to Target Meaning A mapping is created for every Source Meaning where it nearly matches a Target Meaning. Only use this if your source and target meanings are sentences where fuzzy matching would be appropriate. Options are described here.
  • Choose whether to ignore spaces when comparing Source and Targets
  • Also choose whether you want to do Automapping on Source Codes/Meanings that have previously been mapped to the Null Code (or not). If you select the 'Remap Null Code Mapping' option any mappings you previously did to the Target EDT's Null Code (if any) will be retried to see if a proper target mapping is now possible.
  • Press Run Auto Map. The results of the Auto Map will be shown for you to accept or reject.
  • The Auto Mappings panel shows the new mappings that were created by this Auto Map run:

  • The Unmapped Source Codes panel shows the Source Codes that remained unmapped after this Auto Map run:

  • The Unmapped Target Codes panel shows the Target Codes that remain unmapped after this Auto Map run:

  • The Source Code Totals panel shows a summary by Source Code of the mappings that already existed and those added by this Auto Map run:

  • You can either Save Changes if you wish to keep the Auto mappings or Cancel Changes if you wish to try a different algorithm.
  • If you Save Changes the mappings that were generated automatically are added to any you may have created manually in the mapping editor and any created by previous Auto Mapping runs. Auto Mapping never changes any existing mappings, so if you wish to abandon your own manual mappings you need to delete your Code Map and create a new one before you use Auto Map.
  • You can review and edit any automatically created mappings in the Code Map Editor by selecting the Mappings tab:

  • You can repeat Auto Mapping with further choices of algorithm to deal with any remaining unmapped Source Codes.
  • We would welcome feedback to the [Helpdesk] if you have proposals for further algorithms.
