Conversion java.util vectors into sspace.vector.Vector

[samiabenabda...@gmail.com]

Hi Sirs,

I would like to calculate similarities between vectors having the type of java.util.Vector.

When using the class Similarity of sspace, there are problems with this type; even Cast doesn't resolve the problem;

Would you please say to me How to resolve this problem, ?

Hi,

  The java.util.Vector data structure is more like a list for objects, rather than a numeric vector.  When you are trying to compare your java.util.Vector instances, what is in the lists?

  Thanks,

  David

Hi Sir,

Thanks for your response, Vectors contain terms (String) wheighted with tf-idf for some ones, or weight as (1/N) for other ones;

I think the easiest way would be to create two double[] arrays from the tf-idf scores in the java.util.Vector instances and then compare those with the Similarity class.

 Thanks,

 David

Each element of the list in the vector is composed of both String and double value (score);

You should just use the double value then.
