	abstract =	{Information retrieval systems (IRS) are interactive
	information systems for vague queries and uncertain knowledge. The
	application range is not restricted to text retrieval, since the
	approach can be applied to other forms of knowledge as well. In this
	paper, a conceptual model for IRS is presented in which a distiction is
	made between the logic, the layout and the semantic view of database
	objects. Different methods for improving the semantic view are
	discussed. For the intrinsic uncertainty of IRS, a generalization of
	the proof-theoretic view on databases is presented; this approach is
	based on a probabilistic logic. Due to the uncertainty, IRS have to be
	used mostly in interactive mode. Here the user has to consider the
	output resulting from each dialogue step before he decides on the
	further proceeding. For this purpose, IR systems need a variety of
	interactive functions.},
