This paper presents a formal approach to cognitive modeling by utilizing conceptual spaces. Conceptual spaces were introduced by Peter Gärdenfors as geometric and topologic representations that mediate between the symbolic and subconceptual cognitive levels. They can be used for knowledge representation and to explain cognitive reasoning. The goal here is to discuss both the advantages of this ...

The goal of data integration is to provide a uniform access to a set of heterogeneous data sources, freeing the user from the knowledge about where the data are, how they are stored, and how they can be accessed. One of the outcomes of the research work carried out on data integration in the last years is a clear architecture, comprising a global schema, the source schema, and the mapping betwe...

Colour is used in many conceptual models and is discussed intensively since MOODY has published his ‘Physics of Notation’. Yet, choosing the right colour for a construct is difficult but crucial. Using a colour for a certain construct which is not appropriate can lead to visual stress as well as too much or too little emphasis on that construct. The aim of this paper is to give a systematizatio...

Since the early software models, abstraction and conceptual semantics have proven their importance in software engineering methodologies. For example, Object-Oriented conceptual modeling offers the power in describing and modeling real-world data semantics and their inter-relationships in a form that is precise and comprehensible to users. Conversely, XML is becoming the dominant standard for s...

A usable interactive system provides its users with presentation and manipulation of useful concepts for solving their problems at hand without becoming bogged down in accidental features of user interface. It implicates that interaction design is directed by the acquisition and representation of knowledge about the context of use in a way that can be traced back to the users’ problem-solving a...

It is introduced a new concept: H-sets which generalises the notion of fuzzy sets and is based on the concept of hemilattice. Then, we extend the attribute-value conceptual spaces over hemilattices, which gives us a kind of H-set, and prove some of their properties .

The purpose of the chapter is to help someone familiar with DLs to understand the issues involved in developing an ontology for some universe of discourse, which is to become a conceptual model or knowledge base represented and reasoned with using Description Logics. We briefly review the purposes and history of conceptual modeling, and then use the domain of a university library to illustrate ...

Multi-view conceptual modeling provides means for representing, with diagrammatic means, the knowledge describing a "system under study" whose complexity cannot be captured in a single comprehensible representation. Typical examples are available in the field of enterprise modeling, where models are inherently layered or partitioned, a feature that must be enabled at meta-modeling level by mean...
