Semantic matchmaking plays a vital role in the automated and dynamic discovery process of Semantic Web Services and consists in measuring the semantic distance between a requested service and an advertised one. In this paper, an innovative approach to effectively compute the semantic distance between Ontology Web Language for Services （OWL-S） annotated services is proposed. First, an edge-based method for measuring the semantic distance between Web Ontology Language （OWL） concepts is presented. Then, a comparison of the proposed measure and the one presented in a recent related work is made in order to show that our method is more efficient and fine-grained. Finally, some equations to compute semantic matchmaking of service capabilities, which are expressed in terms of inputs and outputs, are presented.展开更多

Even worse were attempts to force Chinese literature into the Procrustean bed of Western literary propositions. How can Chinese literary theory be used more effectively to interpret native literature and culture, or Chinese experience？ How can it throw off Western theoretical models and become a component of the Chinese nation＇s own narrative？ Reconstruction of the discourse system of Chinese literary theory must be a high priority. It is a complex project, one that necessarily entails stepping on to the discourse platform of modernity, accepting various kinds of open dialogue, and thence envisioning a new form of discourse system set amid multilayered overlapping perspectives and even the challenge of different ideas.展开更多
