Retrieval of Information

• more and more on-line info(WEB) is available

  • we need to find a way of finding relevant information
  • one approach-classical database
    due to widely distributed sources of multimedia information-> insufficient
  • other approach-library catalog-pointing at relevant information
    • catalog should not define what is labeling but
    • provide hooks for attaching classification information
    • labeling can be carried out at media item-anchor level
  • storage can be a problem
    • for text items, storage of labeling information will seem larger
    • however, for video items, labeling information will be insignificant
