The Algoreg software lets you define multiple post-filtering sets of parameters that can be used for instance during the Name Search transactional API call. View of default post-filtering settings page ## enc\_U2FsdGVkX19nm1CtkHN7WAHTTi10aVKedSEruy7hHkY=\_enc Here is the list of available fields for a post-filtering set of parameters. These fields can be set for each category of record (PEP, RCA, SIP, SIE) individually. When applying the post-filtering algorithm, we will define the top category of the record (if there are multiple categories) and apply the defined parameters. ## enc\_U2FsdGVkX18doJEAzOwkHspw/fatt1cTtJI6yQh7SEV/2VlJlIEmf9dVUBXcQEbi\_enc ### enc\_U2FsdGVkX1/iLM+rFwre8kO03E1ZaSWbw921RuRubC0=\_enc Alerts with score below specified threshold will not be raised for review. Default recommended threshold is set at 90%. The score is mainly defined using the string distance between input names and output names. See more details here [Go!Scan scoring algorithm](/docs/goscan/scoring/scoring). ### enc\_U2FsdGVkX18Sz17T2RjYPdEtHYEkRbfTnyzlCrK5EumC9VdNyH4xOXPhbS2586Rs\_enc enc\_U2FsdGVkX18/FCZR+1GNcJJEOzq2ojn609qRs1lHzT1glIBlwLKdq7jq/HzDjnZCTw8i4OmOAThRCdufZYG4uSWk+QbQxxNLmfMw8s79trLCFu0dpTJNqvOM3/7pIUlbOZD727dakOuSHumUs9Jo1pCdH8zbnHTqTj8gBlHtCKL+uYGDaNy3tuZTFknFdl/NT1BA3I/X1WPqdmVlMRU51w==\_enc ### enc\_U2FsdGVkX194n2xf5J/ayfecq43oOuDLoqvztWfXbH4=\_enc If not checked, date of birth will be ignored in the scanning process (but not in the Name Search process). If checked, potential alerts can be dismissed by comparing available date(s) of birth with those contained in the watchlists. 4 methodologies are available: * **Exact match**: will only raise alerts with exactly the same date(s) of birth OR none at all * **Delta**: will only raise alerts when date(s) of birth are within a specified range of days OR when no date(s) of birth are provided * **Month and year**: will only raise alerts when month and year match OR when no date(s) of birth are provided * **Year**: will only raise alerts when year matches OR when no date(s) of birth are provided ### enc\_U2FsdGVkX187MkGjykIyU0dFfBG4HRzX05gGWax5hUvMKIhaRXX6pfS6JNpyzAEI\_enc If checked, the country of nationality and/or residence from the result must match the input country of nationality and/or residence. ### enc\_U2FsdGVkX1+hwbVUOi52/wrtYZgZR2694GFR75asmY0=\_enc If checked, the result profile must be marked as active.

Some predefined RegExp are at your disposal, for instance to restrict records from OFAC lists. For more complex settings, please contact us.

For instance you could define a threshold of name matching of 99% but only for PEP records. Or disable inactive SIP/SIE and SAN.
