Limitations of the current Web - Finding relevant information

  • Finding information on the current Web is based on keyword search
  • Keyword search has a limited recall and precision due to:
    • Synonyms :
      • e.g. Searching information about “Cars” will ignore Web pages that contain the word “Automobiles” even though the information on these pages could be relevant
    • Homonyms:
      • e.g. Searching information about “Jaguar” will bring up pages containing information about both “Jaguar” (the car brand) and “Jaguar” (the animal) even though the user is interested only in one of them
