Lessons Learned from Aligning two Representations of Anatomy
The objective of this study is to analyze the comparison, through their results, of two distinct methods applied to aligning two representations of anatomy. The same versions of FMA and GALEN were aligned by each method. 2199 concept matches were obtained by both methods. For matches identified by one method only (337 and 336 respectively), we analyzed the reasons that caused the other method to fail. Alignment 1 could be improved by addressing partial lexical matches and identifying matches based solely on structural similarity. Alignment 2 may be improved by taking into account synonyms in FMA and identifying semantic mismatches. However, both methods identify only a fraction of all possible matches and new approaches need to be explored in order to handle more complex matches.
