چکیده

Information Visualization can be considered as the task of mapping data entities in a source file to representation artefacts in a target visualization format. As such, mapping plays a significant role in this process. The field of Ontology Mapping presents a wealth of work in the information mapping domain which we propose to exploit by applying it to Information Visualization for the Semantic Web. In this paper we describe a User Interface and a tool (VizThis) which demonstrates the proposed approach. We discuss the benefits which a mapping paradigm brings to Information Visualization, including automaticity and rule constraint. The system facilitates automatic mapping while still allowing users the ability to tweak the chosen mappings in order to improve the cognitive value of the visualizations. Additionally, the mapping choices available are constrained by rules governed by the characteristics of both the source and target format. A worked example is provided together with the results of a qualitative user evaluation of the resulting visualizations.

Segmentation Assisted Object Distinction for Direct Volume Rendering

Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...

Navigation and Visualization of Abstractions of Time-Oriented Clinical Data

We describe the methodology and architecture of a knowledge-based, interactive visualization system that enables physicians and medical support personnel to draw conclusions from heterogeneous time-oriented clinical data. Our system employs domain-specific ontologies to produce temporal and statistical abstractions of data, and also as the basis for semantically-based browsing and visualization...

A Bim Assisted Rule Based Approach for Checking of Green Building Design

ABSTRACT: Since the publication of green building standards from the last decade, the designer of green buildings have often encountered the challenges of limited time but considerable complexity in the process of evaluating their design according to the rules specified in the standards. Also, the design process is usually an iterative one, which includes rule-checking tasks that are tedious an...
