The Web of data enables fragments of information to be identified,
  described and connected together in a rich information
  environment. Users requiring information are faced with the problem
  of finding out what information is available, and obtaining
  sufficient fragments to successfully carry out their task.  Systems
  supporting these tasks can use the fragments, descriptions of them
  and relationships among them, to improve query formulation, selection and
  presentation of information. Questions to be answered are: which
  information needs can be better supported, and how can the Web of
  data help.

  We have constructed prototype information systems to investigate
  both the desired functionality from, and user interfaces to, these
  repositories.  Our target user group has been expert cultural
  heritage users.

  Our experience is that grouping and ordering are useful basic
  concepts, where: "ranking" is an often used means of ordering;
  grouping provides a means of indicating the range of concepts
  present in the result set; and different groups may require
  different orderings. Mapping thesauri concepts to more general
  concepts, such as person, location and date/time, has also been
  effective in increasing interface accessibility.
