Attribute reduction is an important preprocessing step in data mining and knowledge
discovery. The effective computation of an attribute reduct has a direct bearing on the …

In many real-life applications, the data collected from different information sources are
always located in diverse sites and characterized by different types of attributes. In this …

The article discusses temporal information systems (TISs) that add the dimension of time to
complete or incomplete information systems. Through TISs, one can accommodate the …

The seminal work of Z. Pawlak 60 on rough set theory has attracted the attention of
researchers from various disciplines. Algebraists introduced some new algebraic structures …

The chapter attempts to give an overview of work done in India in the area of algebraic logic
related to rough set theory. Algebraic structures and associated propositional logics …

Updates in a knowledge base, given as an information system in rough set theory, may need
to be made due to changes in (i) the set of attributes,(ii) attribute-values, or (iii) the set of …

In this article, we aim to bring together the operators of epistemic logic and approximation
operators of rough set theory by combining the ideas from epistemic logic and rough set …

The article analyses prevalent definitions of rough sets from the foundational and
mathematical perspectives. In particular, the issue of language dependency in the …

We study a collection of logics L (T, I) with models based on 'dynamic I spaces', which are
finite sequences of Kripke I frames with a common domain, I being any of the normal modal …
