Hi,
I am trying to create a linear function to influence the similarity
computation. For example -
if tf = 4, f(tf) = 150 * 1 + 150 * 0.3
= 195
The first occurrence is multiplied by 150. The next three occurrences are
mulitplied by 150 and
divided by 10 (3/10).
However, we don't have access to the field name in the function public float
tf(float freq).
Then I thought of modifying the lengthNorm, but there is no input variable
there to
get the term frequency public float lengthNorm(String fieldName, int
numTerms). Is there
any way out ? Is it safe to add a class variable that will save the term
frequency that can be reused
by lengthNorm (assuming that a new Similarity object is constructed for
every request) ?
Thanks.
