Bommel, P. van and Weide, Th.P. van der, Measuring the incremental information value of documents. In: Information Sciences, Nr: 2, Vol: 176, Pages: 91-119, 2006
The incremental searcher satisfaction model for Information Retrieval has been introduced to capture the incremental information value of documents. In this paper, from various cognitive perspectives, searcher requirements are derived in terms of the increment function. Different approaches for the construction of increment functions are identified, such as the individual and the collective approach. Translating the requirements to similarity functions leads to the so-called base similarity features and the monotonicity similarity features. We show that most concrete similarity functions in IR, such as Inclusion, Jaccards, Dices, and Cosine coefficient, and some other approaches to similarity functions, possess the base similarity features. The Inclusion coefficient also satisfies the monotonicity features.

In recent literature it is commonly agreed that the first phase of the software development process is still an area of concern. Furthermore, while software technology has been changed and improved rapidly, the way of working and managing this process have remained behind. In this paper focus is on the process of information modeling, its quality and the required competencies of its participants (domain experts and system analysts). The competencies are discussed and motivated assuming natural language is the main communication vehicle between domain expert and system analyst. As a result, these competencies provide the clue for the effectiveness of the associated process of information modeling.

Grootjen, F.A. and Weide, Th.P. van der, Conceptual Query Expansion. In: Data and Knowledge Engineering, Nr: 2, Vol: 56, Pages: 174-193, februari 2006
This article presents a new, hybrid approach that projects an initial query result onto global information, yielding a local conceptual overview. Concepts found this way are candidates for query refinement. We show that the resulting conceptual structure after a typical short query of 2 terms, contains refinements that perform just as well as a most accurate query formulation.
Subsequently we illustrate that query by navigation is an effective mechanism which in most cases finds the optimal concept in a small number of steps. When an optimal concept is not found, the navigation process still finds an acceptable sub-optimum.

In this paper a method is presented for adding user modelling to (existing) software systems. The method consists of seven steps that lead from initial analysis to the definition and evaluation of the elements needed for the adaptive behaviour.
Along with the method, the central concepts of adaptation elements and adaptation graphs are introduced. An adaptation element can be used to determine the impact of personalisations, while adaptation graphs describe the adaptation in a system as a whole.

We are concerned with a core aspect of the processes of obtaining conceptual models. We view such processes as information gathering dialogues, in which strategies may be followed (possibly, imposed) in order to achieve certain modelling goals. Many goals and strategies for modelling can be distinguished, but the current discussion concerns meta-model driven strategies, aiming to fulfil modelling goals or obligations that are the direct result of meta-model choices (i.e. the chosen modelling language). We provide a rule-based conceptual framework for capturing strategies for modelling, and give examples based on a simplified version of the Object Role Modelling (ORM) meta-model. We discuss strategy rules directly related to the meta-model, and additional procedural rules. We indicate how the strategies may be used to dynamically set a modelling agenda. Finally, we describe a generic conceptual structure for a strategy catalog.

This paper reports on a research effort to better understand the act of modelling. In this paper we describe a formal framework by which the process of modelling can be regarded as involving the selection of more and more refined interpretations in terms of the underlying meta-model of the modelling language used. The resulting framework will be used to create a laboratory setup in which we can more closely study (and support) modelling processes.

In this paper we consider information exchange via the Web to be an information market. The notion of quality plays an important role on this information market. We present a model of quality and discuss how this model can be operationalized.

Bommel, P. van and Hoppenbrouwers, S.J.B.A. and Proper, H.A. and Weide, Th.P. van der, On the use of Object-Role Modelling to Model Active Domains. In: Proceedings of the Workshop on Exploring Modeling Methods for Systems Analysis and Design (EMMSAD`06), held in conjunctiun with the 18th Conference on Advanced Information Systems 2006 (CAiSE 2006), Pages: 473-484, June, 2006, ISBN 9782870375259
Conceptual modelling methods such as Object-Role Modelling (ORM) have traditionally been developed with the aim of providing conceptual models of database structures. More recently, however, such modelling languages have shown their use for modelling (the ontology) of domains in general. In these latter cases, the modelling effort results in a (formally based) conceptual reasoning systems using a domain calculus on top of a domain grammar.
ORM is a member of a family of modelling methods with a well-defined and explicit way of working based on natural language analysis. Their natural language grounding aids in model validation, while their explicit way of working contributes to the repeatability of modelling processes.
As the title suggests, this paper is primarily concerned with the application of ORM 'rigour'.

Rule-driven systems development emphasizes the use of for- malized, declarative rules for the mainstay of its models. The basic un- derlying techniques are decades old, but now their application, that used to concern only operational system and process definition (business logic, data structure) is being extended to much higher-level items such as poli- cies and architecture principles (we focus on the latter here). When using ORM and Ob ject Role Calculus (ORC) for formal modelling of architec- ture principles, the underlying logical principles of the techniques may lead to better insight into the rational structure of the principles. Thus, apart from successful formalization, the quality of the principles as such can be improved. We provide some examples and discussion based on the analysis of principles taken from the The Open Group's Architecture Framework (TOGAF).

Kizza J. Aisbett A. Vince and T. Wanyama. August, Fountain Publishers, Kampala, Uganda, Kampala, Uganda, 2006
This paper is part of an ongoing research effort to better understand the role of models and modeling in the information system development life-cycle. During this life-cycle, several models are produced, ranging from high level sketches, via conceptual models to source code. This paper is part of an ongoing research effort to better understand the act of modeling.
We describe a formal framework by which the process of modeling can be regarded as involving the selection of more and more refined interpretations in terms of the underlying meta-model of the modeling language used. The resulting framework will be used to create a laboratory setup in which we can consequently more closely study (and support) modeling processes.

The Web has, in a relatively short period of time, evolved from a medium for information exchange between scholars to one of the most important media in modern times. This has had a major impact on the infrastructure supporting the Web. Retrieval systems that select relevant resources from the ever increasing volume of resources that are available to us are becoming more and more important. In our opinion, the traditional view on these systems (where `topical relevance` seems to be the key notion) is too limited. The main contribution of this paper is an integral view on a more advanced scheme for search on the web called aptness based retrieval.

Schabell, E.D. and Proper, H.A. and Weide, Th.P. van der, IRIS Publication Management System - the first steps towards realization. Technical report: ICIS-R06008, December, Radboud University Nijmegen, 2006
The IRIS Publication Management System (PMS) has been a long time in coming. It has been a wish of the IRIS department to have a single entry point for dealing with the publications created by its members. The complexities of not only accepting new submissions, but to process these submissions on through the existing institutional publication infrastructure is not a hurdle easily taken.
The submission of both internal and external publications generates not only a collection of doc- uments, but also a very valuable and maybe useful repository of publication data. If this data were to be collected, protected from inconsistencies and properly organized then one would only be limited in her imagination as the the uses that it could be put. To start with, one can begin to pro vide a very interesting playground for departmental retrieval experiments, provide various forms of exportable formats (think of HTML, BiBTeX, text, etc.) and generate any type of organizational reporting as deemed necessary (such as yearly overviews of departmental publications).
This document discusses the definition and design of the IRIS PMS This includes the motivation (why), the (functional) requirements (what), the key design principles as well as the actual design (how).

Weide, Th.P. van der and Bommel, P. van, GAM: A Generic Model for Adaptive Personalisation. Technical report: ICIS-R06022, June, Radboud University Nijmegen, 2006
In this paper we formally define the Generic Adaptivity Model (GAM). This model provides a strong theoretical foundation for adaptive personalisation. Staying true to existing approaches in user modelling, the GAM can be used descriptively as well as prescriptively.
The GAM consists of a number of pillars bound together by a common foundation. In order to allow for extensibility the GAM is domain independent and has little restrictions in applicability. The GAM is embedded in a method for the design of adaptation models for new as well as legacy systems.
