Cloud computing makes an aim come true for the users to get all the resources instantly from various locations that are not known. But there are lot of hurdles in accomplishing this idea in the form of security parameters and backup issues. In this paper we have discussed the solution to there issue by integrating the encryption and server management techniques in order to make a smooth transaction between the user and the server. We propose a new prototype system where we have introduced a governance body which will handle all the transactions from the user to the actual server from where the user is requesting. We have introduced routing table at each end server and middle server (Governance server) so as to get the database of client to server connectivity.

Information extraction (IE) addresses the problem of extracting specific information from a collection of documents. The work presented in this paper described an approach of design an information extraction system; put forward basic system architecture. Describe the detail steps of web information extraction, such as web page organize, rule generate and result show. Finally, successfully extracted information is placed in an XML template, which has been designed to capture information needed in the teaching-learning system. Although the work presented in this paper was restricted to HTML course outlines, the concepts and methods are easily applied to other different domains.

Microblogging services are attracting people and companies to share their ideas and interests. Since the texts of microblog messages are limited, people post URLs to link to other websites for detailed information. Hence, URLs with higher attentions are spread widely and represent popular information. However, not all these URLs are useful. Many of them are spam URLs which are posted by automated agents or by pushing services from other websites automatically. Based on the features of the popular URLs, we divide them into four categories and propose a clustering and classification algorithm to distinguish spam URLs from the really popular ones. Comparative experiments are conducted on English (Twitter) and Chinese (Sina Weibo) messages. We conclude that more than half of the popular URLs are spam. Most of them are pushed from other websites; even the really popular ones gain much attention from the pushing services. Although the proportions of URLs in Twitter and Sina Weibo messages are different, the characteristics of the spam URLs are similar. Our method is efficient for detecting spam URLs and their authors without annotations, and is helpful for both research and business on microblog.

The load balance optimization is an important research topic in a replication system, which will affect the performance a lot. Especially in a capacity restricted system, the load balance will be adversely affected by the strategy to replicate the object. In this paper, an algorithm which will calculate the different replication degree based on the popularity and the size of each object to improve the load balance of the system is proposed. The simulation of a cache system shows that the algorithm could achieve around 50% performance increase compare with the identical replication degree approach as the system is much more balanced and could process much more requests in a certain time period.

In this paper, we propose a novel algorithm that extends the classical probabilistic models to semi-supervised learning framework via manifold regularization. This regularization is used to control the complexity of the model as measured by the geometry of the distribution. Specifically, the intrinsic geometric structure of data is modeled by an adjacency graph, then, the graph Laplacian, analogous to the Laplace-Beltrami operator on manifold, is applied to smooth the data distributions. We realize the regularization framework by applying manifold regularization to conditionally trained log-linear maximum entropy models, which are also known as multinomial logistic regression models. Experimental evidence suggests that our algorithm can exploit the geometry of the data distribution effectively and provide consistent improvement of accuracy. Finally, we give a short discussion of generalizing manifold regularization framework to other probabilistic models.

In this paper, a new wavelength assignment scheme called CSSIR (collision-safe source-initiated reservation) has been proposed for distributed lightpath establishment in GMPLS/PCE based Wavelength-switched Optical Networks (WSONs), which has DIR-like forward blocking probability with SIR-like backward blocking probability. In CSSIR, the PCE selects one wavelength reserved with multi-backup to protect the collision. Simulations are conducted to compare it with SIR&DIR. The results show that CSSIR performs better in total blocking than the others under various traffic loads.

Recently, scientific computing not only brings benefits for science but also brings new challenges for scientists. Therefore, scientists have to face headache “4 how” problems, which are how to know, organize, use and guarantee resources, and as the solution, scientific computing infrastructure should coordinate and organize kinds of capabilities effectively, so as to provide on-demand and safe computing environment for scientists. So, this paper concludes the related research about scientific computing infrastructure in recent years, and base on that systematically analyze the primary demands of infrastructure, and moreover, we propose Capability Meta Model-CMM as the foundation model for kinds of infrastructure; and then, based on CMM we compare kinds of different infrastructure, including grid and cloud computing, from resources, knowledge, quality and security these four aspects, finally, we summarize the problems and challenges the current infrastructure is facing.

After nearly 40 years of development, Intelligent Tutoring Systems (ITS) is moving from research labs into the real world. However, Flight training seems to be somewhat divorced from the mainstream of ITS' application. One reason is the difficulty in the knowledge representation of flight training domain, especially the procedural knowledge of flight maneuvers. After a brief review of knowledge representation in ITS, it is clear that the requirements of KR are naturalness and ease to update. Concept Knowledge Tree (CKT) is an ideal method to represent structural and relational knowledge. Behavior Tree is an elegant and understandable solution to procedural knowledge representation for creating reusable logic. CKT and BT can be combined through script and thus a powerful hybrid knowledge representation method was put forward. With authoring tools, a domain expert can even work without the help of knowledge engineer. The analysis of normal takeoff as an example of a single flight maneuver and the construction of flight maneuver knowledge tree proved the hybrid method an appropriate method to develop the domain model of intelligent flight trainer.
