Our research in KDD has focused on how visualisation can be exploited in the dialectic process of knowledge discovery [6]. Our approach uses a multi-dimensional data visualisation (MDV) technique that builds upon a refined and improved method ...
متن کاملUsing Formal Concept Analysis in Mathematical Discovery
Formal concept analysis (FCA) comprises a set of powerful algorithms which can be used for data analysis and manipulation, and a set of visualisation tools which enable the discovery of meaningful relationships between attributes of the data. We explore the potential of combining FCA and mathematical discovery tools in order to better facilitate discovery tasks. In particular, we propose a nove...

متن کاملChallenges in Knowledge Discovery: Structured Repositories and Multimedia Content
Recent trends in structure and content of global knowledge spaces present new challenges to the field of Knowledge Discovery. Very large, highly structured repositories are increasingly replacing smaller, flat information spaces. Such repositories are often filled with multimedia documents, including image, audio and video data. This publication briefly outlines the underlying trends and discus...
متن کاملDiscovery in Text: Visualisation, Topics and Statistics
Discovery in or understanding of a text collection can be viewed from many angles: the text aspect of the data mining paradigm, the discover aspect of the information seeking paradigm, or the text content aspect of visualisation. This talk will view topic models as a technique within these paradigms. Some visualisations will be reviewed, as well as a variety of different topic models, and some ...
