This paper analyzes the factors technological context that uses Spanish hotels in the e-CRM systems. It is built on the model of Chang, Liao and Hsiao (2005). The data are collected from corporate web and analyzed using Rasch Model (1961). The results indicate that the technological context of e-CRM is based more on the analysis of customer information than in the integration of e-CRM technologies...
It is with the advancement of overwhelming wireless internet access in mobile environments, users and usage data has become huge and voluminous on regular basis. For instance, the financial transactions performed via online by users are unsecure and unauthenticated in many contexts. Methods and algorithms exist for secure data transmission over different channels, perhaps lacks to achieve high performance...
User interest acquisition facilitates customized service by figuring out user preferences in various areas, such as recommendation system and intelligence city. Mobile Internet enriches traditional user behaviors (such as who (user), when (time) and what (content)) by introducing where (mobility) into the analysis of user interest acquisition. However, user mobility is highly predictable, and user...
This paper presents a case study of discovering and classifying verbs in large web-corpora. Many tasks in natural language processing require corpora containing billions of words, and with such volumes of data co-occurrence extraction becomes one of the performance bottlenecks in the Vector Space Models of computational linguistics. We propose a co-occurrence extraction kernel based on ternary trees...
The paper presents considerations on the concept of big data. The aim of the paper is to confront the attempts of defining big data with its common understanding by different groups of users. In this research the group of respondents are students of Warsaw University of Economics. The authors advocate that the student's opinion and attitude to big data can be important regarding the fact that they...
In the context of the EC-funded project Instant Mobility, we have defined a comprehensive architecture for transport and mobility applications that aim to innovate by introducing future Internet technologies to this domain. We have defined an Internet-based “multimodal travel platform” that provides information and services able to support new types of connected transport applications. The considered...
The current economic crisis, combined with growing citizen expectations, is placing increasing pressure on European cities to provide better and more efficient infrastructures and services, often for less cost. This trend has contributed to the growing popularity and use of the term ‘Smart City’ [1]. The Smart City, represent a new way of thinking about urban space by shaping a model that integrates...
Optimisation of resource selection in hybrid cloud data centres depends on the control of resource usage. The primary criterion for this resource selection is economic efficiency. The presented approach considers operational efficiency aspects in service providing and therefore focuses on technical criteria, such as resource load, as well as economic criteria, such as the costs of resource usage....
The vast amount of information on the World Wide Web is created and published by many different types of providers. Unlike books and journals, most of this information is not subject to editing or peer review by experts. This lack of quality control and the explosion of web sites make the task of finding quality information on the web especially critical. Meanwhile new facilities for producing web...
Internet has gained huge popularity over the last decade. It offers its users reliable, efficient and exciting online services. However, the users reveal a lot of their personal information by using these services. Websites that collect information state their practices with data in their privacy policies. However, it is difficult to ensure if the policies are enforced properly in their practices...
Performance advertisers want to maximize the return on their advertising spend. In the online advertising world, this means showing the ad only to those users most likely to convert i.e. buy a product or service. Existing ad targeting solutions such as context targeting and rule-based segment targeting primarily leverage marketing intuition to identify audience segments that would be likely to convert...
Traditional business process modeling approaches focus on the activities, data flows are an afterthought. Concerning cross-organizational collaboration on the Internet, data flow is still far from optimal, causing resource contention and unnecessary data exchanges. In this paper, a data-driven approach to Internet based business collaboration is proposed, which treats data as a centerpiece as data...
Web log files store data related to the use of a website. Analyzing these data in detail is therefore crucial for improving the user browsing experience. However, usually Web log data are stored in flat files in different formats which hinders their analysis, thus obliging to use specific Web log analysis tools. In this context, approaches for structuring Web log data to better analyze them are highly...
The Web has been flooded with highly heterogeneous data sources that freely offer their data to the public. Careful design and compliance to standards is a way to cope with the heterogeneity. However, any agreement and compliance is practically hard to achieve across different communities. In this work we describe a framework that enables the exploitation of content across different scientific disciplines...
With XML becoming the de facto standard for representing and exchanging data on the Internet, the problem of validation of XML data when updated has attracted more and more attentions. The traditional brute-force validation processes the entire updated XML document from scratch, which is less efficient. This paper presents a method for XML incremental validation based on simplified XML element sequence...
With continued expansion of the Mobile Internet users, Mobile Internet has become an important channel for informational goods transacting, and such content providers have indeed become popular with consumers. Recent research has made significant advances in the understanding of various Internet marketing issues. However, an important problem for content providers has remained virtually untouched,...
Methodology of automatic generation of test cases based on Model Driven Architecture is proposed, and its design and implementation have be done. The process of generating test cases is that a platform-independent model is converted into a platform-independent test model through level conversion, and the platform-independent test model is converted into the corresponding test cases through vertical...
A lot of semantic information is lost due to keyword centric approach of information indexing. Web search should be based on `context' of the query and not only on the keywords in query. It is only possible when a context from a query as well as document is sensed and which requires a context based indexing approach. A model for contextual indexing has been proposed which will try to find direct and...
The term Deep Web (sometimes also called Hidden Web) refers to the data content that is created dynamically as the result of a specific search on the Web. In this respect, such content resides outside web pages, and is only accessible through interaction with the web site typically via HTML forms. It is believed that the size of the Deep Web is several orders of magnitude larger than that of the so-called...
XML has become the de facto standard for representing and interchanging data in web-based applications. And XML view, a virtual window for specified users, has been widely applied. In practical system, users encounter the so-called view update problem when they need update source data through the view. For a long time, the view update problem is an open question in database community. With the development...
