3.1 Establishing your expectation's semantic answer & ideal answer


For each expectation, you will need to provide a "semantic answer". Under the "Expectation -> Ideal Answer -> Answer" tab, place the answer that you want the system to compare your student input to. This "Answer" tab is exactly like the self reflection semantic answer.  Generally speaking, the semantic answer does not need to include articles (e.g, the, and, a) or other common words.

The "Spoken" and "Display" tabs next to the "Answer" tab is where you determine how you want you ideal answer to be displayed to your user. The ideal answer is displayed to the user after he or she exhausts each of the expectation's hints or fully covers the expectation. Think of the "Answer" tab as your answer key -- something that should contain the key or important words from your "Spoken" and "Display" text boxes. 

The type of words you include in your answer should be selected based on how you configure your semantic engine



You may also adjust the semantic answer's threshold. Click on the "Threshold" tab next to the "Answer" tab to adjust how much of your user's input should match the semantic answer in order to be considered a good answer by the tutor. If you select a semantics coverage of 1.0, then the user input would need to cover 100% of your semantic answer in order to be considered good. Selecting a low value (.1 - .4) would consider a wider range of student responses as "good". A value of .4 means the user input only needs to cover 40% of the semantic answer to receive good feedback.
