Information Retrieval

Advances in hardware technology require corresponding initiatives in software to create and manage very large information banks. The heterogeneous nature of the information used in current applications, the fact that it may be stored on different types of medium, the fact there may be considerable cross-referencing within and between documents, and the fact that users will often want to access the information in a non-linear fashion suggest that hypertext is a suitable technology to use for the storage of such information.

Many current commercial information retrieval software systems work by searching using one or more search terms specified by the user. There are a number of limitations with this technique:

  • relevant documents may not contain the exact term(s) specified by the user; they may use a synonym or a more or less detailed term;
  • irrelevant documents may contain the specified term, used in a figurative way or in a different sense;
  • the specified term may be too ambiguous or too general, resulting in the recall of irrelevant documents;
  • combinations of terms may express logical relationships rather than syntactic or semantic ones.

One of the main areas of work in the project will be research into the effective and efficient retrieval of information stored in hyperdocuments and the presentation to the user of results of a query. It is expected that the type of information retrieval would not be (solely) statistically-based IR, but rather would involve at least some kind of syntactic analysis of the text, and may involve techniques from the areas of Lexical Semantics, Information Extraction, etc.
