7.9.3.4 Multiple Word Answers

Answers that contain multiple words are treated in a specific way by the Answer Logic. If the final score from a complete string match does not meet the success criteria, individual words in the answer are evaluated. If each individual word in an answer is accepted by any of the algorithms the whole answer is accepted. Multiple word answers with missingextra words must be an exact match to the registered answer. Answers must have the same number of words as the registered answer to be evaluated with Answer Logic. For example: If the registered answer is Mead Elementary School and the answer given at the time of challenge is Mesd Elem Sch: Abbreviation: Mead–Mesd=0; Elementary-Elem=100; School-Sch=100 Fat-finger: Mead-Mesd=75; Elementary-Elem=0; School-Sch=0 Phonetics: Mead-Mesd=0; Elementary-Elem=0; School-Sch=0 Assuming that abbreviation was set to anything besides off and fat fingering was set to medium or high, since all three words would be accepted individually, the whole answer would be accepted.

7.9.4 Configuring Answer Logic

The KBA Answer Logic tab includes controls for the level of each Answer Logic algorithm used for answer validation. The higher the level the less exact answers need to be for acceptance. To configure Answer Logic:

7.10 Customizing English Abbreviations and Equivalences

Answer Logic checks if the answer provided by the user matches closely to the ones provided during registration. Answer Logic, in part, relies on pre-configured sets of word equivalents, commonly known as abbreviations. Although there are several thousand English abbreviations and equivalences in the English version of Oracle Adaptive Access Manager, customers can perform customizations per their business requirements. For example, the customer might want the following to be considered a match. The out-of-the-box English abbreviations and equivalences are in a file named, bharosa_auth_abbreviation_config.properties. Changes cannot be made to this file.
