With the development of Web technology and more kinds of information, how to provide high quality, relevant search results become a huge challenge to the current Web search engines. We analyze the shortcomings of PageRank algorithm and Weighted PageRank algorithms and make targeted improvements. By judging the relation between different web pages based on web content, the improved PageRank algorithm...
According to the application requirements of the Water Resources Data Centre (WRDC), a scene analysis model is proposed for organizing and applying the objective information under the condition of big data. This model focuses on the generation and application of the digital scene, supporting big data processing, and establishing a new application mode of WRDC. This new model has the ability to combine...
The opinion leaders play an important role in the process of network public opinion spreading. In order to quickly and efficiently discover the opinion leaders, this paper analyzes the characteristics of complex networks in social networks and proposes density-based spatial clustering of applications with noise algorithm based on local community detection method. With Sina micro-blog user as the research...
Usually, there will still be data conflicts left in the event mentions after the events have been co-reference resolution. This paper presents a novel experiments-proven solution to the conflicts of event mentions by first categorize the conflicts of events into named entity conflicts, semantic conflicts and data presentation conflicts and then take advantage of the D-S evidence theory in dealing...
In the original live-wire algorithm, optimality is defined as the minimum cumulative cost path from a seed point to another, where the cumulative cost of a path is the sum of the local edge costs on the path. Therefore, the optimal path between two seed points is restricted not far away from the straight line between these two points. Consequently, when delineating a boundary with acute concaves and...
Base on innovation resistance theory, this research builds the model of factors affecting consumers' resistance in using online travel in Thailand. Through the questionnaires and the SEM methods, empirical analysis results show that functional barriers are even greater sources of resistance to online travel website than psychological barriers. Online experience and independent travel experience have...
The paper provides the software architecture, design method and implementation techniques for a Web service-based logistics information system which is based on Browser, Web Server, Application Server, Data Structure. An example is given to illustrate how to fulfill the communication between the server and the client.
In this paper, a modified K-means based RBFNN is discussed. To improve the performance of RBFNN, an initial cluster centers (ICCs) selection strategy is proposed for K-means algorithm. The algorithm takes breadth preferred subset of samples as ICCs to cover the sample space using greedy strategy. The results shows that the proposed algorithm can improve the performance of RBFNN remarkably in chaotic...
Variable-fidelity optimization (VFO), which utilizes the precise value of high-fidelity (HF) model and underlying trend of low-fidelity (LF) model, has solved many computationally expensive problems by simulation-based design. Though it has been developed rapidly in recent years, the simpler and cheaper ones are still needed. In this paper, a new optimization framework based on Kriging method with...

This paper studies several identification methods for Hammerstein systems with piece-wise linearities. By using the key term separation technique, the model of the nonlinear Hammerstein systems be changed to an identification model, then based on the derived model, a stochastic gradient identification algorithm, a forgetting factor stochastic gradient algorithm and a modified stochastic gradient algorithm...
Dynamic time warping algorithm is widely used in similar search of time series. However, large scales of route search in existing algorithms resulting in low operational efficiency. In order to improve the efficiency of dynamic time warping algorithm, this paper put forward an improved algorithm, which plans out a three rectangular area in the search area of the existing algorithms, search path won't...
Recently, we have seen a growing trend in the reconstruction of accurate geometric models, acquired by an active method such as laser scanning or structured light. In this paper, we address the problem of creation of 3D head models from multiple RGB-Depth cameras. We propose a quick capture procedure that aims at achieving high accuracy and low-cost 3D head models with high quality. This is processed...
Road traffic saturation data is streaming at unprecedented speed and must be dealt with in a timely manner. In the paper, we put forward a real-time calculation method of road traffic saturation based on big data storage and computing. We will calculate the road traffic saturation data via adjacent traffic checkpoint while the computing and storage of road saturation based on Spark big data processing...
In order to provide good quality of survivability in the WDM (Wavelength Division Multiplexing) optical network and keep the network load in a good condition, a game based muti-domain protection scheme is proposed in this paper. Game theory, Nash equilibrium and Pareto Optimality of micro-economics are introduced in this scheme for considering benefits of both users and network providers to guarantee...
