Formal Semantics of SGs. This first section ends by the fundamental theorem stating that if there is a homomorphism from . to . then . entails . and if . entails . then there is a homomorphism from . to . (i.e., a soundness and completeness theorem of SG homomorphism with respect to entailment)..FOL is used to give a sema

Palpitation

Tractable Casesrithms compute a filter that allows to enumerate the solutions. We point out the equivalence between hypergraph-acyclic BGs and . BGs, which correspond to the guarded fragment of existential conjunctive positive first-order logic. We then briefly present generalizations of acyclicity to . and ., and

Nested Conceptual Graphseasonings must follow the hierarchical structure, because in an NTG the hierarchy is explicitly and graphically represented. Nested graphs can also be interesting whenever large graphs have to be manually constructed, as the separation of levels of reasoning increases efficiency and clarity when ext

Section 2.4 introduces another way of defining the subsumption relation by sets of elementary graph operations. There is a set of . operations and the inverse set of . operations. Given two BGs

In fact, normal SGs and normal BGs can be identified, which emphasizes the importance of normal BGs. The notion of ., which is specific to SGs, is introduced
