Conceptual Modeling Of Multimedia Databases The gap between the semantic content of multimedia data and its underlying physical representation is one of the main problems in the modern multimedia research in general, and, in particular, in the field of multimedia database modeling. We believe that one of the principal reasons of this problem is the attempt to conceptually represent multimedia d...

This paper discusses several important future research directions in conceptual modeling. Since this field is very broad, the list of topics discussed here is not an exhaustive list but rather the “partial” composite views of the coauthors on the important issues from their own perspectives. Some of the important issues are omitted because they were covered extensively in [1], and the readers s...

The creation and manipulation of conceptual shapes need different modeling techniques from what are available in present CAD systems. Conceptual modeling techniques are supposed to provide more flexible interaction and mimic working with true materials. Therefore, this paper proposes a new computer internal modeling technique that supports the natural ways of exteriorizing shape concepts as wel...

Wednesday 20 February 13.30-14.30 Theme Session 1: Modeling Conceptual Change Concepts, Conceptual Change, and Explanatory Identities Paul Thagard, University of Waterloo A theory of conceptual change requires a theory of concepts, but current accounts of concepts are explanatorily inadequate. A theory of concepts is being developed as part of the new synthesis in cognitive science accomplished...

Conceptual information modeling is a well-established practice, aimed at preparing the implementation of information systems, the specification of electronic message formats, and the design of information processes. Today’s ever more connected world however poses new challenges for conceptual information models, as different models should enable mutual connection and reconciliation, even when d...

The paper presents the framework for conceptual modeling which has been used in on-going project of developing fact extraction technology on textual data. The modeling technique combines the usage of conceptual graphs and Formal Concept Analysis. Conceptual graphs serve as semantic models of text sentences and the data source for formal context of concept lattice. Several ways of creating forma...

Although it is widely accepted that UML could be used both for modeling software and the problem domain that is supported by an information system, its suitability for the latter in the early development phases has been questioned. Also, it is argued by many researchers that early development phases are critical for successful and cost efficient information system development. In view of this, ...

Conceptual models of information systems emerge as the result of cooperation among diierent user groups. There are however few research eeorts focused on providing collaboration support for this activity. This thesis aims at suggesting methods and tools originating from CSCW research eld for supporting collaborative conceptual modeling. A framework for studying collaboration support for user pa...

Navigation is a fundamental human activity and an integral part of everyday life. Humans use their knowledge about previous experiences with geographic space to find their way. Considerable research in the areas of cognitive science, psychology, and artificial intelligence has been carried out to examine the means by which humans navigate. Humans need to abstract from reality and form concepts ...
