As one foundational technology of cloud computing, services computing is playing a critical role to enable provisioning of software as a service (SaaS). However, how to effectively and efficiently discover proper availab.e services from the cloud of resources remains a big challenge. This paper reports our continuous efforts on semantic services discovery. We extend the Support Vector Machine (SVM)-based text clustering technique in the context of serviceoriented categorization in a service repository, and propose an iterative process to incrementally enrich domain ontology. A popular Web 2.0 mashup platform is used as a testbed;and preliminary evaluation results are reported. © 2011 IEEE.

For a long time, the fault diagnosis and assessment for power transformer is a quite complex and difficult problem. In this paper, we propose a transformer fault diagnosis method based on fuzzy theory. The dissolved gas concentrations are set as the inputs of the system, and a fuzzy system group is appLied to build the intelLigent diagnosis system. The parameters of the system, including the input dimension, output dimension, and the membership functions, can be set up in whole or separately in the system. To test the effectiveness of the proposed method, it is appLied to the practice dataset. The experiment results show that the fuzzy system group improves the accuracy of assessment greatly compared with fuzzy system and BP neural networks. Also, the knowledge system of power transformer fault diagnosis can be built up completely by the proposed method. © 2011 IEEE.

Since the investors often react to news and consequently make stock prices move, financial news has an impact on stock prices. However, the price adjustment process is a complex one. In this paper, a statistical learning methodology has been proposed to analyze the time lag between the price moves and the released news. We firstly set up a news-price mapping model to study the relationships among the price moves and the volume of the news articles. Cross validation has also been used to test the time lag. Experiments have been conducted by using the daily data sources in 2002 in the Hong Kong stock exchange market, and the results have showed that in most cases, the time lag is approximately equal to 1 day. © 2011 IEEE.

For parallel applications running on high-performance clusters, performance is usually satisfied without paying much attention to energy consumption. In this paper, we develop a new scheduling algorithm called Energy efficient Scheduling Algorithm based on DVS and Dynamic threshold (ESADD), which combines dynamic threshold-based task duplication strategy with dynamic voltage scaling (DVS) technique. It first exploits an optimal threshold to get the optimal task grouping and leverage task duplication algorithm to reduce schedule length and communication energy, and then schedules the applications on DVS-enabled processors that can scale down their voltages to reduce computation energy whenever tasks have slack time due to task dependencies. Using simulations we show our algorithm not only maintains good performance, but also has a good improvement on energy efficiency for parallel applications. © 2011 IEEE.

PageRank has been widely used in ranking retrieval results on the web, finding the top influential papers in citation networks or detecting valuable users in online social networks. However, in practice, it is usually hard to obtain a complete structure of any above networks to rank nodes. Thus, some researchers have begun to explore how to get estimated ranks efficiently without acquiring the whole network. They have proposed some approximating methods, however, it is difficult to determine which method is the best one or which is suitable to a certain application. In this case, we set experiments in small-world and scale-free generated networks to certify the feasibility and characteristics of four approximating methods. We also use eleven real networks to mention different optimal conditions for these methods. We find the DIGRank method performs better than other local estimation methods in almost every given subgraph. Besides, Mean field approach method tends to perform well in networks that have low average shortest path length, small amount of nodes with the same low indegree, or weak community structure. Finally, we apply the most versatile method DIGRank to Sina micro-blog website to precisely classify users in a group as elites, grassroots or mummy users. © 2011 IEEE.

Image retargeting quality assessment

Content-aware image retargeting is a technique that can flexibly display images with different aspect ratios and simultaneously preserve salient regions in images. Recently many image retargeting techniques have been proposed. To compare image quality by different retargeting methods fast and reliably, an objective metric simulating the human vision system (HVS) is presented in this paper. Different from traditional objective assessment methods that work in bottom-up manner (i.e., assembling pixel-level features in a local-to-global way), in this paper we propose to use a reverse order (top-down manner) that organizes image features from global to local viewpoints, leading to a new objective assessment metric for retargeted images. A scale-space matching method is designed to facilitate extraction of global geometric structures from retargeted images. By traversing the scale space from coarse to fine levels, local pixel correspondence is also established. The objective assessment metric is then based on both global geometric structures and local pixel correspondence. To evaluate color images, CIE lab.color space is utilized. Experimental results are obtained to measure the performance of objective assessments with the proposed metric. The results show good consistency between the proposed objective metric and subjective assessment by human observers. © 2011 The Author(s).

A new 5-round distinguisher of AES with key whitening is presented by using the properties of its round transformation. Based on this distinguisher,we present new meet-in-the-middle attacks on reduced AES considering the key schedule and the time-memory tradeoff approach. New attacks improve the best known meet-in-the-middle attacks on reduced AES presented at *** reduce the time complexity of attacks on 7-round AES-192 and 8-round AES-256 by a factor of at least 28. Moreover,the distinguisher can be exploited to develop the attack on 8-round AES-192.

Similarity matching is one of the most important operations for data mining over time series. But previous works mainly focus on certain data. With the development of the internet of things and sensor networks, uncertain time series are emerging from various sources, which is a new challenge for data processing. In this paper, a novel similarity matching algorithm over uncertain time series is proposed based on a simple model representing the uncertain time series. According to the certainty of the query time series and the database, similarity matching is classified to three types. Then a certain time series is extracted to represent the original uncertain time series. Finally, a similarity search algorithm for certain time series is adopted. Experimental evaluation shows that our algorithm has high efficiency for similarity matching over uncertain time series. © 2011 IEEE.

The crosscutting phenomena has been found at architectural level. Using aspects, AOP effectively solves the code tangling problem produced by the crosscutting phenomena at code level. This paper presents an approach to aspect-oriented software architecture design by introducing the concept of aspects into the process of software architecture design. We describe the regular architectural structure with the basic design elements of ACME, and represent the architectural aspects with the proposed extension of ACME. The example of an Online Bookstore system has been used to illustrate our proposal. © 2011 IEEE.
