    Traditionally, knowledge representation (KR) languages have declarative semantics based on classical logic and have a concrete syntax that is textual. Conversely, programming languages (PL) have mainly procedural semantics and are represented in visual terms. Moreover, PLs can only represent procedures at a very low level. Our conceptual programming language (CPL) bridges this gap, while still ret... View full abstract»

    Specifying varying speeds and temporal relationships is necessary when programming graphical animations, but support for temporal programming has usually been done by adding new language features to a VPL, and these features must be mastered over and above the other aspects of the VPL. However, some researchers have believed that time should be able to be treated like just another dimension. We ex... View full abstract»

    SD2 is a system of Venn-type diagrams that can be used to reason diagrammatically about sets, their cardinalities and their relationships. They augment the systems of Venn-Peirce diagrams investigated by Shin (1994) to include lower and upper bounds for the cardinalities of the sets represented by regions of diagrams. We summarise their syntax and semantics and introduce inference rules for reason... View full abstract»

    Computer science educators have traditionally used algorithm visualization (AV) software to create graphical representations of algorithms that are later used as visual aids in lectures, or as the basis for interactive labs. Based on ethnographic field studies we have conducted in an undergraduate algorithms course, we advocate an alternative teaching approach in which students use simple art supp... View full abstract»

    The paper proposes an extension of layered graph grammars (LGGs), which have been introduced for the definition of visual languages (VLs). Offering new constructs like negative application conditions (NACs) it allows one to produce more concise VL definitions. A new layering condition and critical pair analysis are the prerequisites for a new parsing algorithm which avoids the exponential behaviou... View full abstract»

    We propose a model for interactive animation (IAN) of structured objects in multimedia documents. The model naturally integrates usual multimedia elements (text, image, video, sound) with motion and graphical changes of geometric objects, but also with user and inter-object interaction. Animation is defined in a declarative and highly structured manner: a set of objects with their composition rela... View full abstract»

    An important question of knowledge management is how we can support domain experts in formulating their domain knowledge and in making this expertise available via knowledge based systems. Critiquing systems are a special kind of knowledge based system. These systems provide context sensitive advice, and rationale to an artifact (for example charts, Web pages and so on) designed by a user. This is... View full abstract»

    Venn diagrams and Euler circles have long been used to express constraints on sets and their relationships with other sets. However, these notations can get very cluttered when we consider many closed curves or contours. In order to reduce this clutter, and to focus attention within the diagram appropriately, the notion of a projected contour, or projection, is introduced. Informally, a projected ...

    Executing object-oriented programs have a complex structure consisting of numerous objects connected by interobject references. This structure, called the program's object graph, is hard to understand, and this complicates learning, teaching, debugging and maintaining object-oriented programs. While visualisation can be used to display object graphs, the size and complexity of typical object graph... View full abstract»

    Positional grammars are a formalism for the definition and implementation of visual languages. They have already been used in the past as part of the VLCC system (Visual Language Compiler-Compiler) for the definition and the implementation of visual environments for editing and compiling flowcharts, chemical structures, combinatorial networks, electric circuits, etc. The authors introduce the eXte...

  • Incorporating image segmentations into a visual query language for content-based image retrieval

    Publication Year: 2000, Page(s):233 - 234
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (228 KB)

    Image retrieval systems have often used color and texture features successfully, but shape features have not been as successful, largely because of the difficulty of specifying them. Traditional image segmentation algorithms tend in many cases to produce results that users find unsatisfactory as either representations of the image or as components of an interpretation of the image. We have found, ... View full abstract»

    Visual programming languages aim to promote usability, but are rarely examined for it. One reason is the difficulty of designing successful experimental evaluations. We propose the cognitive walkthrough as an aid to improve experimental designs. This is a novel application of an HCI-derived technique designed for evaluating interfaces rather than experiments. The technique focuses on the potential... View full abstract»

    The richness of semantic content of visual representation is related to the fact that it has an aspect right only for interpretation by human. When videos are stored in a database their retrieval is normally performed simply by name. The need to have information on their content, during the retrieval phase, is growing and its extraction constitutes a challenge if performed automatically by the ret... View full abstract»

    Algebraic specifications have a proven record for the development of software that is precise, consistent, complete and unambiguous. However, despite their usefulness there has been limited uptake by software engineers. The authors attribute this apparent discrepancy, at least in part, to a question of usability and understandability. This paper describes an approach to addressing these problems t...
