HYPER MODEL MANAGEMENT SYSTEMS
In this paper we study the integration of Model
Management and Hypertext systems to produce a Hyper
Model Management System (HMMS). Model Management
Systems constitute a class of software that
is designed to support the construction, storage, retrieval,
and use of models in the context of decision
support systems (DSS). Hypertext systems allow users
to split information into data fragments which the user
cart browse to find information by taking non-linear
paths in computer based texts. It has been suggested
that DSSs should be conceived as environments which
support decision making. We support the view that
such environments can be readily provided for the subtask
of model management by hypertext systems. The
different kinds of model knowledge can be captured
within different types of hypertext nodes and the relationships
among these can be maintained by hypertext
links. In this paper we describe some aspects of
model management where hypertext will have a significant
impact. However, plain hypertext is ineffective
in dealing with the dynamic nature of information in
model management tasks where data is revised, models
executed, and reports are created on the fly. Dynamic
domains require dynamic hypertexts. In this paper we
also study the requirements for dynamic hypertexts.
These can be satisfied within the class of generalized
hypertext systems by using special hypertext nodes and
links which we describe. We explore different architectures
to integrate MMS and Hypertext systems to
obtain HMMSs. This paper emphasizes the need for a
shift to integrating Model Management and hypertext
technologies.Information Systems Working Papers Serie

The effect of WWW document structure on students' information retrieval
This experiment investigated the effect the structure of a WWW document has on the amount of information retained by a reader. Three structures common on the Internet were tested: one long page; a table of contents leading to individual sections; and short sections of text on separate pages with revision questions. Participants read information structured in one of these ways and were then tested on recall of that information. A further experiment investigated the effect that 'browsing' - moving between pages - has on retrieval. There was no difference between the structures for overall amount of information retained. The single page version was best for recall of facts, while the short sections of text with revision questions led to the most accurate inferences from the material. Browsing on its own had no significant impact on information retrieval. Revision questions rather than structure per se were therefore the key factor
Image retrieval by hypertext links
This paper presents a model for retrieval of images from a large World Wide Web based collection. Rather than considering complex visual recognition algorithms, the model presented is based on combining evidence of the text content and hypertext structure of the Web. The paper shows that certain types of query are amply served by this form of representation. It also presents a novel means of gathering relevance judgements
Personalised multilingual hypertext retrieval: An overview
The aims of the workshop on Personalised Multilingual Hypertext Retrieval (PMHR) are twofold: to set the scene in this challenging area, allowing the diļ¬erent communities engaged in related research topics to meet and to determine a program of actions to undertake; to devise a strategy for the evaluation of PMHR systems, which should deļ¬ne the
collection of resources to use to evaluate such systems together with the evaluation metrics to use. The workshop results will be of use in the design of personalised tools that can help end-users fully beneļ¬t from the use of distributed multilingual hypertext content
User centred evaluation of an automatically constructed hyper-textbook
As hypertext systems become widely available and their popularity increases, attention has turned to converting existing textual documents into hypertextual form. An important issue in this area is the fully automatic production of hypertext for learning, teaching, training, or self-referencing. Although many studies have addressed the problem of producing hyper-books, either manually or semi-automatically, the actual usability of hyper-books tools is still an area of ongoing research. This article presents an effort to investigate the effectiveness of a hyper-textbook for self-referencing produced in a fully automatic way. The hyper-textbook is produced using the Hyper-TextBook methodology. We developed a taskbased evaluation scheme and performed a comparative usercentred evaluation between a hyper-textbook and a conventional, printed form of the same textbook. The results indicate that the hyper-textbook, in most cases, improves speed, accuracy, and user satisfaction in comparison to the printed form of the textbook
