Abstract

Cloud computing is clearly one of today‟s most enticing technology areas to its cost-efficiency and flexibility. There is a growing trend of using cloud services for ever growing storage and data processing needs. However, adopting a cloud computing paradigm may have positive as well as negative effects on the security of service consumers. This paper primarily aims to highlight the major security challenges existing in current cloud computing Service Provider Software as a Service (SaaS). We also describe some elements of our vision. The core issue is that with the advent of the cloud, the cloud provider also has some control of the cloud users data. We aim to provide tools supporting the current capabilities of the cloud while limiting cloud provider control of data and enabling all cloud users to benefit from cloud data through enhanced business intelligence.

Abstract

Cloud computing is clearly one of today‟s most enticing technology areas to its cost-efficiency and flexibility. It‟s a future computing, there is a growing trend of using cloud services for ever growing storage and data processing needs. However, adopting a cloud computing paradigm may have positive as well as negative effects on the security of service consumers. This paper primarily aims to highlight the major security challenges existing in current cloud computing service provider giving Software as a Service (SaaS). We also describe some elements of our vision. The core issue is that with the advent of the cloud, the cloud provider also has some control of the cloud user‟s data. We aim to provide tools supporting the current capabilities of the cloud while limiting cloud provider control of data and enabling all cloud users to benefit from cloud data through enhanced business intelligence.

Abstract

To gather useful information from the web has become a challenging issue for users. Current web information gathering systems attempt to satisfy user requirements by capturing their information needs. For this purpose, user profiles are created for user background knowledge description. When representing user profiles many models have utilized only knowledge from either a global analysis or user local information. Through the user profiles, a knowledge representation and reasoning is proposed in this paper. The model constructs user personalized ontologies by extracting global analysis and discovering user background knowledge form user local instance repositories. The proposed ontology model in this paper provides a solution to emphasizing global and local analysis in a single computational model. This ontology model becomes a successful model by evaluating it and it is compared against the benchmark models in web information gathering and also the model has extensive contributions to the fields of Information Retrieval and Information Systems.
