Table 9: Manual examination of 300 randomly selected expressions of a concept with the lowest harmonic distance score.
['distance (<=)', '20', '40', '60', '80', '100', '120']
In order to examine this question we randomly select 300 concepts and their lowest h_dist mention from UMLS-SSD. All selected mentions had a different harmonic score, whereas the largest score of the subset was 120. The selected mentions have been manually evaluated according to our two definitions by one of the authors. The analysis shows that 75% of all terms are technical expressions according to definition 1 and 90% according to definition 2. In this way we can see that a harmonic distance below 60 leads to a high accuracy, which supports our assumption. The larger the distance the more the accuracy decreases. However the score decreases faster using definition 1.
