Upon repeated analysis of distance metrics, discrepancies were observed. This appears to be caused by the YTEX package attempting to cache LCS's between CUIs, leading to inconsistent outputs when making repeated calls to the similarity service. By disabling the cache, each distance computation is forced to locate the LCS, ensuring consistent output even when calling multiple CUI pairs in succession.
From my testing, the performance impact of disabling the cache is negligible. Until further investigation can determine why the cache is causing inconsistencies, it is advisable to keep it disabled.
