Philgoo Han writeup of Wang and Cohen

This is a review of Wang_2008_iterative_set_expansion_of_named_entities_using_the_web by user:Ironfoot.

• Iterative SEAL
  • Limitation of SEAL on using larger seeds => iterative SEAL
• Fixed Seed Size
  • Introduce two seeds at every iteration
• Increasing Seed Size
  • Introduce one seed at every iteration and combine to previous seed set. (increase by one)
  • Until maximum values reached
• Bootstrapping
  • The new seed introduction in FSS and ISS can be done in unsupervised manner.
• Ranking Methods
  • Random walk with restart
  • PageRank
  • Bayesian sets
  • Wrapper length
  • Wrapper frequency (baseline)
• Experximent result
  • Supervised: FSS converge faster than ISS (RW = BS > ...)
  • Bootstrapping: ISS converge to improve but FSS fail (RW > BS > ...)
    • ISS used in this paper seems closer to a variation of FSS. The sead set doesn't increases only twice.
    • Might it be more worth to improve the tool itself than finding a way to use the tool in a more clever way?
