An Information System organized as Stratified Hypermedia

چکیده
In this paper we investigate the relation between modern hypertext approaches and conventional data modelling techniques, such as PSM. We show how query formulation in a traditional information system can be regarded as a stratified hypermedia featuring two levels of abstraction. The first level of abstraction covers the structure of the stored information, and the second level the information itself. The investigations provide us with the mechanism of query by navigation as a novel avenue for improved query formulation in information systems.

Organising an Information System as Stratified Hypermedia
The information disclosure problem begins with a person having an information need that they wish to fulfil (figure 1). Formulation of this need leads to a request q, which has to be matched against the characterization of information objects which are available in the information base (also referred to as information carriers or documents). This process of matching yields a measure for the rel...

متن کاملQuery Formulation as an Information Retrieval Problem
Query formulation in the context of large conceptual schemata is known to be a hard problem. When formulating ad-hoc queries users may become overwhelmed by the vast amount of information that is stored in the information system; leading to a feeling of lost in conceptual space. In this article we develop a strategy to cope with this problem. This strategy is based on ideas from the information...
متن کاملMESH: A Model-Based Approach to Hypermedia Design
The term hypermedia denotes an approach to computer data organization in a manner similar to the functioning of the human brain. In essence, human cognition is organized as a semantic network in which related concepts are linked together. New information we come across is integrated into our mind’s semantic structures of existing knowledge. These structures allow for the stored information to b...
