The insufficiency of consumer's trust is one of bottlenecks to China online shopping, and now most Web sites resort to the renowned third party or trust displaying mechanism to promoting consumer's trust. However, whether the two kinds of trust promotion strategies above have the same effect? And whether their own attributes and assurance contents have the significant influence on consumer's trust?...
In order to simulate the dynamic of bid accurately, power generation companies select behavioral decision-making from a finite set of different behavioral decision-makings. Each generation company has taken the probability of decision-making behavior depending on the profits of power generation companies. Using more sophisticated decision-makings may require extra information costs. The selected probability...
This paper presents method for split-step backward Euler scheme in regime-switching models. We generalize the classical Black-Scholes model to encompass regime-switching properties. The Black-Scholes model is shown to generate significant pricing errors when a regime-switching process governs underlying asset returns. In addition, regime-switching option values are shown to generate implied volatility...
This paper will introduce the principle of obtaining seismic wavepsilas torsional acceleration component from itpsilas translation component, and it gets the torsional component of EI Centro wave and Ninghe wave through the Matlab calculation program.Using ANSYS software, the spatial elastic-plastic analysis model of frame structural is established,and then, the translational and rotational component...
In this paper, we propose an evolutionary approach to rank association rules for classification. The association rules are ranked by their support, confidence and length in one of the most important associative classification method, Classification based on Multiple Association Rule (CMAR). However, from some empirical studies, we find that if the rules are ranked by some equations first, the classification...
While Shamirpsilas identity-based public key cryptosystem does not need the certificates, the key escrow of userpsilas private keys is inherent in such scheme. In 2003,the concept of certificateless signature scheme was introduced. In this new paradigm, the necessity of certificates has been successfully removed and the key escrow problem does not exist. Based on the ideas of certificateless signatures...
This paper analyses the principle and development potential of precision agriculture, then provides the elementary scheme of precision agriculture in China based on applied mathematical model and information technology.
source, specifically Yahoo's ldquosuggested keywordsrdquo. These keywords are based on co-occurrence data across queries. The classifier, which is built offline with training data, makes use of the top-n results during training, but not duing testing. Thus, there is an asymmetry between the training and testing data. We
Traditional information retrieval (IR) systems evaluate user queries and retrieve/rank documents based on matching keywords in user queries with words in documents.These exact word-matching and ranking approaches ignore too many relevant documents that do not contain the exact keywords as specified in a user query
This paper proposes the method to recommend music using lyric network. This method corresponding to more than thousands of musics. The authors focus each lyric of the music. Keywords representing music are extracted from its lyric by combining TF-IDF method and principle of discriminant analysis. Lyric network is
This paper presents a solution to classifying sentences with multi-labels. This problem is an essential part to a semantic search process. Sentences or keywords with correctly automated labelling can enhance the efficiency and performance of the search. The technique introduces a vector space of relevance for keywords
important in IoT for the Information Systems Research community as well as the first overview of the keywords that the authors use to describe their work in IoT- related context. Publications from the IoT context, including some of the topic areas in smart environment from the AIS electronic library were analyzed towards their
Traditional behavior analysis based on the keywords or server log is so simple that it is difficult to meet the individual requirements of the user information search. This paper introduces the Multi-agent intelligent technology into four kinds of search behavior analysis, including the user search keywords, the
base stations to determine the location of the mobile. The holder's trajectory can get through the statistics of large-scale location about anonymous user. Even in the special position the mall can push information keywords and make the service management more intelligent. When mobile phones become an indispensable things
image retrieval system uses image low level feature such as content or visual properties of an image for retrieval. Image high level features that is image context such as keywords, tags, captions related to images are also important as they play key role in reducing the semantic gap more effectively when compared with
student's answer against an answer-key that comprises key phrases of the solution and alternatives, if any. We rely on five algorithms from literature on natural language processing to assess various aspects of a student's answer, such as the quantity and extent of match between keywords in a student's answer and the answer
Traditional Information Retrieval (IR) models are based on bag-of-words paradigm, where relevance scores are computed based on exact matching of keywords. Although these models have already achieved good performance, it has been shown that most of dissatisfaction cases in relevance are due to term mismatch between
With the increase in the number of user reviews on user review sites, useful tools for extracting good and bad points of services so that users can easily and intuitively understand the quality of the services are required. If the annotations are selected from the pre-defined list, there can always be missing keywords
proved that the system able enough to fit data in finding historical pattern even had to face with chaos and complex. Distribution data and non-linear differential equation are caused of chaos and complex respectively. Keywords- chaos and complex, economic condition, non-linear differential dynamic, time series, genetic
used to process the captured signals. The eye-tracker device that we have implemented uses keywords technology. It has been tested on a set of subjects by using different parameters for the pupil detection algorithm in order to determine the system optimal performances (algorithm running time and accuracy).
