As a model of concept representation, ontology has widely applied to various disciplines. In this book, we consider some topics on the sparsity and vulnerability of ontology graph and ontology algorithm. First, the Hermite ontology learning algorithm is presented, and two simulation experimental results show that the proposed new technologies have high accuracy and efficiency on ontology similarity measuring and ontology mapping in certain applications. Second, we determine the isolated toughness condition for an ontology graph to be fractional (f, n')-critical and fractional (f, n')-critical...

Chemical compounds and drugs are often modeled as graphs where each vertex represents an atom of molecule and covalent bounds between atoms are represented by edges between the corresponding vertices. This graph derived from a chemical compounds is often called its molecular graph and can be different structures. In this book, based on mathematical derivation, we determine the several important indices of certain special molecular structures.

In this book, we determine several important topological indices of polynomials of Wiener index of some widely used chemical structures.
