Aligning representations of anatomy using lexical and structural methods

AMIA Annu Symp Proc. 2003;2003:753-7.


Objective: The objective of this experiment is to develop methods for aligning two representations of anatomy (the Foundational Model of Anatomy and GALEN) at the lexical and structural level.

Methods: The alignment consists of the following four steps: 1)acquiring terms, 2) identifying anchors (i.e., shared concepts) lexically, 3) acquiring explicit and implicit semantic relations, and 4) identifying anchors structurally.

Results: 2,353 anchors were identified by lexical methods, of which 91% were supported by structural evidence. No evidence was found for 7.5%of the anchors and 1.5% received negative evidence.

Discussion: The importance of taking advantage of implicit domain knowledge acquired through complementation,augmentation, and inference is discussed.
