As a close business with customers, travel agency should focus on customer relationship management, which is very important. This paper attempts to combine the concept of customer relationship management and the processes of traditional travel agency marketing to construct the system architecture, considering the actual situation and specific requirements of a travel agency, combining with norms and standards of the management of travel agencies industry, as well as, using the current popular system architecture B/S (Browser/Sever) Mode. By extensively studying the theory of software engineering, database theory and object-oriented languages and Web programming, management information systems analysis and design process of travel agency marketing is discussed in detail based CRM.","PeriodicalId":360193,"journal":{"name":"J.

To provide connectivity to mobile users with same IP address despite of their change in location or point of attachment, the location information of mobile users must be kept up to date. Managing location information of such users basically needs information to be exchanged between different network entities. The transmission of such messages consumes bandwidth, incurred processing time and transmission cost. This cost is normally referred as signaling overhead caused by mobile users. The signaling overhead is mainly dependent on the frequency of location change caused by the movement of users and number of messages to be exchange to complete the location update process. Hierarchical arrangement of anchor agents can reduce such signaling overhead but degrades scalability in presence of large number of mobile users. The objective of this work is to analyze mathematically the location update frequency and cost in an N layered hierarchical architecture for IPv6 based network in wireless environment. The intention is to find optimal levels of hierarchy in terms of frequency and cost of location update to suggest a scalable IPv6 based mobile architecture. Result obtained from mathematical calculation shows that three levels architecture may provide optimal values for these two performance parameters.

The system gives priority to the construction of mini-ontology. When the user submits query keywords to the deep web query interface, the returned result will pass through the prior three components; after that, the final execution result will be returned to user in a unified form. This paper adopted an extraction method that is different from the general ontology extraction. More specifically, the ontology used in extraction here is dynamic evolution, which can adapt various data source better. Experimental results proved that this method could effectively extract the data in the query result pages.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.

SNRMDV is used as the criterion of cross-validation (CV) in our method, which is defined as the ratio between the difference of medians of decision values and the sum of the standard deviations from the medians. Compared with the traditional cross-validation accuracy (CV-ACC) method, CV-SNRMDV makes use of the information of sample distribution and decision value. Consequently CV-SNRMDV overcomes the disadvantage of CV-ACC. The experiments show our method obtains a better test accuracy on the simulated dataset, while the test accuracies on benchmark datasets are close to CV-ACC.","PeriodicalId":360193,"journal":{"name":"J.

But the performance of ANNs is sensitive to the number of neurons, and chieving a better network performance and simplifying the network topology are two competing objectives. While Genetic Algorithms (GAs) is a kind of random search algorithm which simulates the nature selection and evolution, which has the advantages of good global search abilities and learning the approximate optimal solution without the gradient information of the error functions. This paper makes a brief survey on ANNs optimization with GAs. Firstly, the basic principles of ANNs and GAs are introduced, by analyzing the advantages and disadvantages of GAs and ANNs, the superiority of using GAs to optimize ANNs is expressed. Secondly, we make a brief survey on the basic theories and algorithms of optimizing the network weights, optimizing the network architecture and optimizing the learning rules, and make a discussion on the latest research progresses.

The objective of this work is twofold. Firstly, we investigate the efficiency of multi-instance learning in bankruptcy prediction. For this reason, a number of experiments have been conducted using representative learning algorithms, which were trained using a data set of 150 failed and solvent Greek firms in the recent period. It was found that multi-instance learning algorithms could enable experts to predict bankruptcies with satisfying accuracy. Secondly, we explore the effectiveness of multi-instance learning techniques in detecting firms that issue fraudulent financial statements (FFS). Therefore, a number of experiments have been conducted using representative learning algorithms, which were trained using a data set of 164 fraud and non-fraud Greek firms. The results show that MIBoost algorithm with Decision Stump as base learner had the best accuracy in comparison with other multi-instance learners and single supervised machine learning techniques.","PeriodicalId":360193,"journal":{"name":"J.
