As you say, the time to make an object needs a long time, so my program
gets two data files and tries to process multiple queries.
The problem is that once an uninitialized value is returned for the word
that is not on Wordnet, the following results for whatever become
uninitialized value if a new object is not created, so at the worst case,
I need to create an object as the same number of comparisons.
For example,
#1. Simialarity (cost#n#2, price#n#2) = 1
#2. Simialarity (Routing, Path) = uninitialized value error
#because Routing is not on WordNet
If I make comparisions in order of #1, #2 and #1, then the results are
"1", "uninitialized value" and "uninitialized value",
so my program creates a new object whenever producing "uninitialized
value", which makes my program slower.
Is it my mistake in package installation or what you are supposed to do in
the design?
Best,
Hyunyoung
