Sensor networks have significantly reduced the costs of data gathering in the environment. Real-time sensor data are being used for scientific and industrial purposes such as calibration of forecast modeling, environmental monitoring and decision-making ...

In this paper, we analyse the factors affecting the network security of a gas SCADA system. We model the security problem in the SCADA system into an online digital intelligent defensing process, including all reasoning judgment, thinking and expression ...

In cloud, service performances are expected to meet various QoS requirements stably, and a great challenge for achieving this comes from the great workload fluctuations in stateful systems. So far, few previous works have endeavored for handling ...

The SCADA system plays an important role in monitoring the long distance operation of mass pipeline network, which may experience huge damage due to landslides geological hazards. It is critical to detect the deformation and displacement of rock to ...

Due to current real-time data compression algorithms is not efficient enough, we have proposed a two-phase real-time data compression algorithm which can be very fast in data compression with high compression rate. The algorithm can adapt to both text ...

Twig pattern matching plays an important role in XML query processing, holistic twig pattern matching algorithms have been proposed and are considered to be effective since they avoid producing large number of intermediate results. Meanwhile, automaton-...

On the foundation of analyzing the existing classification, an acquisition method of extension transformation knowledge based on Decision Tree classification has been proposed The new-bored method re-mines and transforms the decision tree rules to "can'...

Block-based matrix multiplication plays an important role in statics computing. It is hard to make large scale matrix multiplication in data statistics and analysis. A flexible parallel runtime for large scale block-based matrix is proposed in this ...

With the rapid development of web social networks and its integration into our daily lives, interactivity and participatory between people and web have made the web social networks play an important role in the information security, trade relations, ...

Recent threats caused by worms on wireless sensor network are recognized as one of the most serious security threats. Due to the limit of the hardware, there wouldn't many protect technologies applied in the sensor nodes. Therefore, it is necessary to ...

With the rapid growth of information on the World Wide Web, social recommendations have appeared as one of the most important roles attracting growing attentions from researchers. Social recommendations enable a form of efficient knowledge for users and ...

This paper designs and builds a serviceability analysis framework for electric vehicle sharing systems based on the vehicle movement data stream collected from the taxi telematics system. For the given sharing station distribution and the relocation ...

Customer value (CV) can scale the relative essentiality on the customer for an enterprise according to an enterprise as a main body of value and the customer as an object of value at the same time. CV is varied continually in a changing environment. ...

In the literatures, hash-based association rule mining algorithms are more efficient than Apriori-based algorithms, since they employ hash functions to generate candidate itemsets efficiently. However, when the dataset is updated, the whole hash table ...

Given a search query, most existing search engines simply return a ranked list of search results. However, it is often the case that those search result documents consist of a mixture of documents that are closely related to various contents. In order ...

This paper compares the correlations between visual similarity of real-world images and different ontology-based concept similarity in order to find a novel measurement of the relationship between semantic concepts (objects, scenes) in visual domain ...

Asynchronous invocations are needed in the context of distributed object frameworks to prevent clients from blocking during remote invocations. Popular Web Service frameworks offer only synchronous invocations (over HTTP). When a client with ...

With the rapid development of new social networks, such as blog, forum, microblog, etc, the publication and propagation of information become more convenient, and the interactions of users become more active and frequent. Discovering the influencers in ...

For the vast amounts of data on the Web, this paper presents an extraction method of semantic label of entity relation in the tourism domain based on the conditional random fields and rules. In this method, firstly making use of the ideas of ...

Recognition of chinese personal names becomes a difficult and key point in chinese unknown word recognition. This paper explored the context boundary of names and the law of names. The context boundary of names is concentrated, which can reduce ...

There exist several powerful and popular academic search engines, such as Microsoft Academic Search, Google Scholar and CiteSeerX, etc. However, query answering is now being required by users in addition to existed keyword and semantic search. Academic ...

Automatically constructing knowledge bases from free online encyclopedias has been considered to be a crucial step in many internet related areas. However, current research pays more attention to extract knowledge facts from English resources, and there ...

Human Flesh Search Engine (HFSE) is a phenomenon of massive researching using Web media such as blogs and forums with a purpose of exposing personal details of perceived misbehaviors. With the increasing efficiency and convenience of the Web, Human ...

Forward secrecy is one of the important properties of remote user authentication schemes to limit the effects of eventual failure of the entire system when the long-term private keys of one or more parties are compromised. Recently, Tsai et al. showed ...

The view of data provenance provides an approach of data abstraction and encapsulation by partitioning tasks in the data provenance graph (DPG) of scientific workflow into a set of composite modules due to the data flow relations among them, so as to ...

For various applications in today's service-oriented enterprise computing systems, such as process-oriented service discovering or clustering, it is necessary to measure the distance between two process models. In this paper, we propose a quantitative ...

Efficient supply chains are a vital necessity for many companies. Supply chain management acts on operational processes, divergent and consolidated information flows and interaction processes with a variety of business partners. Efforts of recent years ...

The prevalence of smart devices allows people to record their space-time status. This paper focuses on exploiting user space-time status and the related semantic information for service recommendation. Firstly, event DAG is employed to organize the ...
