Role Attribute 1.0

, 2012
The Role Attribute defined in this specification allows the author to annotate markup languages with machine-extractable semantic information about the purpose of an element. Use cases include accessibility, device adaptation, server-side processing, and

Hybrid data attribute reduction based on neighborhood rough set

Journal of Intelligent Systems
The attribute reduction in rough set theory has considerable value in areas such as pattern classification, knowledge extraction, and data mining. Hybrid information systems usually contain discrete classification attributes and continuous numerical ...

Attribute processing in environmental choice analysis: implications for willingness to pay [PDF]

Data from a discrete choice experiment is used to investigate the implications of failing to account for attribute processing strategies (APSs). The research was designed to elicit the economic benefits associated with landscape restoration activities ...

Soft discernibility matrix and attribute reduction for information systems

Tongxin xuebao, 2009
A new concept of soft discernibility matrix was proposed, and related theorems were given. By using soft discernibility matrix,attribute reductions of incomplete information systems, fuzzy value information systems and vague sets value information ...

IF-EMD-SPA: An Information Flow-Based Neighborhood Rough Set Approach for Attribute Reduction

Applied Sciences
High-dimensional mixed data often lack a unified semantic representation for continuous and discrete attributes, which hinders mixed-attribute similarity modeling and can result in unstable reducts and overfitting in existing neighborhood rough set (NRS)

Fuzzy modified great deluge algorithm for attribute reduction

, 2014
This paper proposes a local search meta-heuristic free of parameter tuning to solve the attribute reduction problem. Attribute reduction can be defined as the process of finding minimal subset of attributes from an original set with minimum loss of ...
