Concept Recommendation System for Cloud Services Advertisement

Cloud computing is a major trend in Information Technology (IT), which has witnessed high adaption rate for cloud solutions. Software-as-a-Service (SaaS) providers compete to address nearly every business and IT application needs. Heterogeneous cloud service advertisements make it difficult for potential users to discover the required service offers. To overcome this problem, the cloud service registry is fundamental for both the cloud users and providers. It provides detailed information about SaaS offers from different providers in one place, which increases the services reachability. In this paper, we focus on the business perspective of the SaaS services, which has not received eligible consideration by existing literature. We propose a semantic-based system for unified SaaS service advertisements. We introduce a template for the service registration, a guided registration model, and a registration system. Moreover, we present a semantic similarity model for services metadata matchmaking. Prototypical implementation and evaluation proved the proposed system effectiveness.
