This homework requires you to organize a set of terms into a
classification hierarchy.

As a starting point, you will use the Unified Medical
Language System (UMLS) Semantic Network. The UMLS is a
project funded by the National Library of Medicine to create
a vocabulary useful for bibliographic retrieval and for
clinical medicine. It exploits terms from many other
vocabularies (MeSH, ICD-9, SNOMED) and defines them in a
UMLS "MetaThesaurus," which can be used to translate similar
concepts among the source vocabularies. The UMLS Semantic
Network is used to organize this very large list of terms.
The highest level terms (most general) are shown on the back
of this page.

Your job is to create a classification hierarchy for the
terms listed below (much like we did during the class
exercise). You may use the UMLS semantic network as a
starting point. Do not simply stick all these terms in the
UMLS classes You will need to create new classes to better
organize the terms. For example, you want to create a class
called "symptoms," which is a child of the UMLS "finding"
class, then add "ophthamologic symptoms" as a child of
"sypmtoms," and then put all the symptoms related to the
eyes under that class. Please redraw whatever parts of the
UMLS Semantic Network that you use (that is, every term in
your vocabulary should should have the term "entity" as its
ultimate ancestor).

The following terms are taken from homework 2. You may need
to use a medical dictionary  (eg, Dorland's Medical
Dictionary in the library) to understand what some of them
mean.
