A pattern identifies a problem and provides the specification of a generic solution to that problem. Conceptual modelling patterns are aimed at representing a specific structure of knowledge that appears in different domains. Roles are meant to capture dynamic and temporal aspects of realworld objects. This paper identifies common semantics of different role models found in the literature. More...

Assessing the level and quality of collaboration between students working in project teams is a complex task. The main goal of our study was to develop and validate an online questionnaire for assessing the quality of distance teamwork collaboration in a project-based systems modeling course. The research goals included assessing the transactional distance (TD) perceptions among peer students w...

In this paper, we present a conceptual data model for multimedia database applications based on ExIFO2 model. The ExIFO2 data model is chosen as the conceptual model since it handles both complex objects along with their uncertain and imprecise properties. We enhanced this conceptual model in order to meet the multimedia data requirements. In addition to uncertain and imprecise information, we ...

Traditionally, the research and practice of conceptual modeling assumed relevant information about a domain is determined in advance to be used as input to design. The increasing ubiquity of systems – characterized by heterogeneous and transient users, customizable features, and open or extensible data standards – challenges a number of long-held propositions about conceptual modeling. We raise...

This study explores the differences between conceptual data models designed by expert and novice data modelling practitioners. The data models are evaluated using a number of quality factors synthesised from previous empirical studies and frameworks for quality in conceptual modelling. This study extends previous studies by using practitioners as participants and using a number of different qua...

The creation of a conceptual schema is a critical feature of the software production process. The conceptual schema should represent the structure and behavior of the information system so that the users can perform their organizational tasks. For this reason, the organizational context needs to be the starting point for the generation of an initial conceptual schema. This approach allows us to...

Discovering a set of domain classes during object-oriented analysis is intellectually challenging and time-consuming for novice analyzers. This chapter presents a taxonomic class modeling (TCM) methodology that can be used for object-oriented analysis in business applications. Our methodology helps us discover the three types of classes: (1) classes represented by nouns in the requirement speci...

When modeling expertise from multiple experts, expertise conflicts among the expertise models of the different experts must be tackled, so as to build their common expertise model. The domain level of an expertise model can be represented using Sowa’s conceptual graph formalism. This paper presents a method for conflict management during knowledge modeling from multiple experts: this method is ...

Recent studies state the importance of conceptual modeling in simulation life cycles. Proper development of a conceptual model is critical for expressing the context, elements, relationships, limitations and purpose of the simulation study. Surprisingly there are many simulation projects that have no explicit conceptual model, a poorly or only partially developed conceptual model, or incomplete...
