[Go] addition of localization specific process terms ?

[Alexander Diehl]

I want to add my agreement to the words of Val and David.  It is much 
simpler to use a pre-composed existing term in annotation.  One aspect 
of the annotation process I feel is over looked as we add more 
complexity to the annotation process is that post-composition adds a 
significant bit of time to the annotation process, resulting in fewer 
annotations overall and lower metrics for the database and grant.  While 
it is important to do detailed and correct annotations whenever 
possible, anything we can to do to increase throughput, such as 
precomposing likely terms, is beneficial.  I'm not saying we should add 
all possible combinations of X and Y, just the appropriate ones.  This 
is one of the main reasons for having annotators lead ontology 
development and holding ontology content meetings where expert 
biologists can discuss processes actually seen in nature, so that the 
appropriate combinations of X and Y are added.

And knowing which pre-composed terms to use is a matter of training and 
experience, both in general biology, and in annotation.  There's no way 
around it.
