Application of System to Research Abstracts

• Give the system examples of the model

  • 100 Abstracts (IEEE Trans. on PDS) divided into 692 labeled ‘Steps Units’ (Step unit was the sentence)
  • 554 Step Units used for ‘training’ the system
  • 138 Step Units used for ‘testing’ the system

• Tell the system what ‘features’ to look at

  • All words (no punctuation, numbers)
  • Position of step unit in abstract (i.e. 1st, 2nd, 3rd, …)

• (Reduce ‘Noise’ in Features)

  • Rank words by ‘importance’ using frequency
  • Rank words by ‘importance’ using ?2 measure
  • Use the first x no. of words (2208 words total)
