Help in Options for combining term vectors- LSA

[Ibtehal Baazeem]

Dear S-Space developers , 

I have a question regarding document representation in Latent Semantic Analysis:

http://fozziethebeat.github.io/S-Space/apidocs/edu/ucla/sspace/common/DocumentVectorBuilder.html#USE_TERM_FREQUENCIES_PROPERTY

It is written that “Options for combining term vectors include summation, average, and term frequency weighting”, but I just found how to use term frequency option. 

I am currently using term frequencies,

  Properties vectProp=new Properties();

  

    //The property to specify if term frequencies should be used when combining term vectors.

      vectProp.setProperty("USE_TERM_FREQUENCIES_PROPERTY","edu.ucla.sspace.common.DocumentVectorBuilder.usetf”);

                DocumentVectorBuilder builder = new DocumentVectorBuilder(sspace,vectProp);

Could you advise how to use the average weighting ASAP?

Many Thanks,
