A Fuzzy Logic-Based Approach to Uncertainty Treatment in the Rule Interchange Format: From Encoding to Extension [chapter]

Jidi Zhao, Harold Boley, Jing Dong
2013 Lecture Notes in Computer Science  
To prepare DL as well as LP extensions, we present a fuzzy extension to Description Logic Programs (DLP), called Fuzzy DLP, and discuss its mapping to RIF.  ...  However, the set of truth values in the RIF Basic Logic Dialect (RIF-BLD) currently consists of only two values (t and f), although the RIF Framework for Logic Dialects (RIF-FLD) allows for more.  ...  We also present a fuzzy extension to Description Logic Programs, namely Fuzzy DLP. We address the mappings between fuzzy DL and fuzzy LP within Fuzzy DLP, and give Fuzzy DLP representations in RIF.  ...
