Operations on soft sets revisited
Ping Zhu, Qiaoyan Wen
Soft sets, as a mathematical tool for dealing with uncertainty, have recently gained considerable attention, including some successful applications in information processing, decis…
Information-theoretic measures associated with rough set approximations
Ping Zhu, Qiaoyan Wen
Although some information-theoretic measures of uncertainty or granularity have been proposed in rough set theory, these measures are only dependent on the underlying partition and…
A note on communicating between information systems based on including degrees
Ping Zhu, Qiaoyan Wen
In order to study the communication between information systems, Gong and Xiao [Z. Gong and Z. Xiao, Communicating between information systems based on including degrees, Internati…
Homomorphisms between fuzzy information systems revisited
Ping Zhu, Qiaoyan Wen
Recently, Wang et al. discussed the properties of fuzzy information systems under homomorphisms in the paper [C. Wang, D. Chen, L. Zhu, Homomorphisms between fuzzy information syst…
Some improved results on communication between information systems
Ping Zhu, Qiaoyan Wen
To study the communication between information systems, Wang et al. [C. Wang, C. Wu, D. Chen, Q. Hu, and C. Wu, Communicating between information systems, Information Sciences 178…
