SWANSEA UNIVERSITY REPORT SERIES VizThis : Rule-based Semantically Assisted Information Visualization

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.

متن کاملSegmentation 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 ...

متن کاملEquational and Rule-Based Programming: Visualization, Reliability, and Knowledge Base Generation
This document describes developing an environment for effective use of functional/equational programs and rule-based expert systems. There are significant advantages in using these paradigms for reliability, parallelism, and accumulation of expertise in knowledge bases. The environment will make it easier to understand and use these paradigms, construct more reliable systems, and automatically ...
