A review of Wang_2009_automatic_set_instance_extraction_using_the_web by user:rbalasub

The paper describes ASIA which is a system to generate hyponyms of a given class. The system works in 3 stages

  1. The first stage uses methods used by Hearst et al. to extract a large set of noisy candidates. All language dependent features are eliminated to keep the system language-agnostic.
  2. SEAL is then used to expand the set of noisy candidates
  3. iSEAL is then used to bootstrap SEAL and to be resistant to noisy seeds.

Experimental results show that the system works better than the state of the art baselines.
