Configuring Topic Elements

A Topic element specifies that a Topic must be found (or must not be found) by SpeechMiner in a call in order for the call to be assigned to the Category.

When you add a Topic element to an expression (see Inserting Elements into an Expression), the fields required to select and configure the element are added to the right panel below the Type field. You can use these fields to select the Topic and specify its required number of occurrences in the call, its strictness level, and its timing constraints.

To add a Topic element:

1. Under Topic, select the Topic.

2. Modify the following settings as necessary:

   Setting | Description
   Not found | Select this option if you want the condition to include all calls except those in which the Topic was found. (For additional information, see Configuring Category Conditions.)
   At least __ Occurrences | Specify the minimum number of times the Topic must have been found in the call in order for the condition to be met.
   At least __ Strictness | Select the minimum level of strictness for the recognition of the Topic; if the Topic recognition does not meet this minimum, SpeechMiner proceeds as if the Topic was not found. Note that this only limits strictness beyond the Topic's defined strictness.
   From | Define the earliest position in the call audio at which the Topic may be found, in seconds, and then select one of the following types of reference points: Secs Abs: The number of seconds is defined relative to the beginning of the call Secs Abs from End: The number of seconds is defined relative to the end of the call (i.e., the Topic must be found no earlier in the call than this number of seconds from the end of the call) Secs Rel to Start of Prev: The number of seconds is defined relative to the beginning of the previous item in the expression; this option will only work if the operator connecting the two elements is Conditional AND (->). Otherwise, selecting this is the same as selecting Secs Abs. Secs Rel to End of Prev: The number of seconds is defined relative to the end of the parent item; this option will only work if the operator connecting the two elements is Conditional AND (->). Otherwise, selecting this is the same as selecting Secs Abs from End.
   To | Define the latest position in the call audio at which the Topic may be found, in seconds, and then select one of the types of reference points explained above.
   Speaker Type | Select a speaker type if the Topic must be found when the selected type of speaker is speaking, or ANY to include all speaker types.
