The participants of the experiment were presented three simulated information needs with
corresponding search results retrieved from our semantic search system. Each query was submitted three
times to the semantic search system, but using different FVs that were created as result of different
parameters (i.e., LQP, MQP, and HQP settings presented in section 4.3). In total nine queries were
submitted and nine evaluation pages were generated each having 10 top ranked documents.
Consequently, each user needed to evaluate 90 retrieved documents.
