In order for this feature to be available, please ensure that the the Question Similarity Search check box is selected for the application in the License Server configuration. If this is not selected, you are not able to use the Enemy Detection feature in the application. If it is not available, then you need to contact Pearson VUE Tech Support.


The Item Similarity menu allows the Item Bank Manager to make use of the semi-automated Enemy Detection feature built into the application to specify Item Enemy associations. This feature calculates and proposes pairs of items between which Enemy association can be established. The Item Bank Manager then selects the pairs of items to which he/she confirms the Enemy association.


The accuracy of this feature increases and it becomes particularly useful when there are a large number of items in the Item Bank. If the number of items is less, then the results may not be as accurate or useful.


As you can see in the above screenshot, there is no Item Comparison Criteria set by default. The Item Bank Manager must set this criteria by clicking the Set Criteria button as described in Item Similarity Criteria Configuration. The Enemy association between item pairs is decided later as detailed in Retrieve Item Pairs to Decide Enemy Relationships by Item Bank Manager or in the Item Similarity tab by the Project Manager.
