   I am a Computer Science undergraduate. I am trying to do a project in   
   " Wrapper Induction" domain. I am in the literature survey phase now.   
   I wish to know 3 things:   
      
   [1] Metrics:   
      
   I have come across 6 different kinds of metrics:   
   Precision   
   Recall   
   F measure   
   Expressive   
   Efficiency   
   Compression ratio [Valter crescenzi's Roadrunner]   
      
   Is there any possible metric?   
      
   [2] Labels in Wien system [Nick Kushmerick's]   
      
   What do the labels actually stand for? The values which change and   
   need to be extracted or the pair of constants along with their values?   
      
      
   [3] Partially extracted Labels [Road Runner using RISE]   
      
   Road Runner has used a unique of comparing  it's system on Wien Test   
   Bed. They say that some of the labels are extracted and some parially   
   extracted. Can anyone give a small example of any html page which can   
   demostrate this "partially" extracted labels?   
      
      
   Best Regards   
   Niket.
