Knowledge trees in complex knowledge bases
The paper treats the use of knowledge trees for knowledge bases with linguistic information. Here the knowledge base consists of inferential, data, and relational (joint propositional) statements containing linguistic expressions modelled by respective possibility distributions. Some problems are studied and relevant algorithms making use of knowledge trees are presented answering questions of i) value, ii) truth (given by a fuzzy set in [0,1]), including truth of qualified statements.
