Semantic Rendering of Data Tables - Multivalued Information Systems Revisited
نویسندگان
چکیده
Data tables provide a convenient means of representation of descriptive information about objects. They serve also as standard input for data analysis tools or theories. In this paper we focus our attention upon the special class of data tables, namely multivalued information systems introduced by Z. Pawlak and E. Orłowska in the early 80s. The main idea presented in the paper is to interpret multivalued information systems as semantically processed single valued data tables. This interpretation allows us to describe classical rough set theory, dominance-based rough set theory, and formal concept analysis within the framework of multivalued information systems.

1 Achieving Direct Volume Visualization with Interactive Semantic Region Selection
Interactive direct visualization of 3D data requires fast update rates and the ability to extract regions of interest from the surrounding data. We have implemented MultiValued Classification volume renderers on a general purpose multiprocessor graphics platform (Pixel-Planes 5) that are faster than any yet reported (2 -15 frames per second). We have joined one of them with a sophisticated syst...

Methods: This descriptive st...
متن کاملAn Extension of Semantic Proximity for Fuzzy Multivalued Dependencies in Fuzzy Relational Database
Following the development of fuzzy logic theory by Lotfi Zadeh, its applications were investigated by researchers in different fields. Presenting and working with uncertain data is a complex problem. To solve for such a complex problem, the structure of relationships and operators dependent on such relationships must be repaired. The fuzzy database has integrity limitations including data depen...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
