The recall estimate was produced by manually inspecting 6,000 of the initial 14,383 candidate terms, asking the experts to mark all the terms judged as "good" domain terms, and comparing the obtained list with the list of terms automatically filtered by OntoLearn (the phase of terminology filtering described in Section 3.1).
of the feedback obtained from the tourism experts, we decided that experts' interpretation difficulties could indeed be alleviated by associating a textual definition with each new concept proposed by OntoLearn.
