Information table with with added semantics about attributes

One can added semantics about attributes with respect to their importance. In this group of papers, we focus on user ordering (or user preferences) of attributes, which provides a qualitaive representation of the importance of attributes. User preferences of attributes are useful in the construction of reducts.

Information table with with added semantics about attribute values

Classical rough set model only consider the trivial equality relation "=" on attribute values. In general, one may consider other semantics on attribute values. Three specific types of semantics can be considered, namely, any binary relation, order relation, and neighborhood systems.

Analysis of Information Table with Orderings on Attribute Values
(Ranking, ordinal classification or sorting problems)

The following group of papers deals with a particular types of binary relations (i.e., orderings). The problem of discovering of ordering rules is addressed.


Evaluation measures of ranking, ordinal classification, and sorting systems


This group of papers concern measure for evaluating ranking in information retrieval. The results are applicable ordinal classification or sorting system in general.
