A Digital Assets Navigating System Based on FCA

Abstract

Formal concept analysis (FCA) has been developed to have a wide range of applications. A number of researchers have proposed several FCA lattice structures for Information Retrieval. In this paper, a Web-based digital assets navigating system is designed based on FCA. In the proposed design, several meta-templates tailored for certain metadata standards are used to processing the various asset types , and DC acts as the core managed and lattice-context extracting metadata standard to which other meta-templates can easily mapping. The second way to form lattice context is extracting the terms from the content of document-alike assets using the BC method. At last we suppose a Web-based navigating interface using an eye-frame to show or hide parts of the lattice via interactive shifting of a focus concept node.
