Read code changes on dictionary basis

Post by lordnedox » Sun Oct 10, 2010 5:23 am

Hi,
i'm trying to read the following codes:

obtaining the following result:
dictionary it: ((21457
dictionary en, fr: (C1457)

and
Image
obtaining the following result:
dictionary it, en: 8E00728l»89
dictionary fr: 8E00728489

Could someone explain me how is the dictionary used on simple codes like these?

I tried also setting the allowed characters string, only to numbers and capital letters, and then i get the first "8" recognised as a "S". How is this algorithm working too?

Thanks
Regards
Marco

Hi,

The dictionary files are use to make a choice between several possibilities. This choice depends on the dict file content...
I can not resume the algorithm behavior in a few words since it is a very complex process. But in a future release we will try to add feature to increase/decrease the trust in the dictionaries content to provide better result on ref numbers.

Kind regards,

Loïc
