Analysis of Gradient Descent Ontology Algorithm in Special Setting

Yun Gao, Wei Gao

Abstract


Ontology as a useful tool has wide applications in various fields and raises widespread attention of scholars. And the ontology concept similarity calculation is an essential problem in these application algorithms. An effective method to get similarity between vertices on ontology is based on a function which maps ontology graph into a line and maps every vertex in graph into a real-value. The similarity is measured by the difference of their corresponding scores. In this paper, we focus on an ontology setting which uses truth function to label each pair of vertices and the ontology preferences are given randomly from some distributions on the set of possible undirected edge sets of an ontology graph. Based on the techniques of statistical learning theory, the learning rates for gradient descent ontology algorithm in such setting with general convex losses are obtained.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
