Ontology-based Integration of Web Navigation for Dynamic User Profiling
Anett HOPPE, Ana ROXIN, Christophe NICOLLE 10
The development of technology for handling information on a Big Data-scale is a buzzing topic of current research. Indeed, improved techniques for knowledge discovery are crucial for scien-tific and economic exploitation of large-scale raw data. In research collaboration with an in-dustrial actor, we explore the applicability of ontology-based knowledge extraction and repre-sentation for today's biggest source of large-scale data, the Web. The goal is to develop a profil-ing application, based on the implicit information that every user leaves while navigating the online, with the goal to identify and model preferences and interests in a detailed user profile. This includes the identification of current tendencies as well as the prediction of possible future interests, as far as they are deducible from the collected browsing information, and integrated expert domain knowledge. The article at hand gives an overview on the current state of the re-search, the developments made and insights gained.

A Trivia like Mobile Game with Autonomous Content That Uses Wikipedia Based Ontologies
Bogdan IANCU 25
The mobile devices are everywhere and the gaming industry has an important market share on this field. This paper aims to present a new approach of game which generates autonomous its content, without human intervention, by using existing facts from the semantic version of Wikipedia, called DBpedia. At the beginning a short introduction of the studied field and of the used terms and technologies is presented. There are also remembered similar approaches and different struggles from this domain. In the middle part the architecture and the logic of the system are shown. The paper ends with some conclusions and future plans.

Contribution and Trend to Quality Research—A Literature Review of SERVQUAL Model from 1998 to 2013
Ya Lan WANG, Tainyi LUOR, Pin LUARN, Hsi Peng LU 34
While many past studies focus on service quality research, especially using the “SERVQUAL”, little is known about the mechanics of this model. Motivated by the need to gauge the contribution of the SERVQUAL model, this study reviews 367 SSCI and SCI articles that are related to the SERVQUAL model from 1998 to 2013. We identify key factors and conduct a survey to search for related articles in the Institute for Scientific Information (ISI) Web of Science (WOS) database. Research contributions are measured, ranked, and presented based on quantity and quality metrics. The trends of SERVQUAL model research from our results are discussed. This study shows that the SERVQUAL model was one of the hot research topics by academic researchers and significantly contributed to service quality research.

Usage of Facebook by University Students in Romania and Lithuania: A Comparative Study
Dragoş Daniel IORDACHE, Costin PRIBEANU, Vincentas LAMANAUSKAS, Loreta RAGULIENE 46
Facebook is a social networking website which gained a huge popularity in the last decade among university students. Recent papers show that Facebook favors meeting new people, staying in touch with friends, getting useful information and knowledge, sharing of documents, joining groups and participating in group discussions. Although the usage of social networking websites in general and Facebook in particular has been extensively studied, this is little data available regarding the variations across countries, towns, and gender. This paper aims to comparatively analyze the results of two studies carried on in Lithuania and Romania. The data show that the reasons why university students are using Facebook differ from country to country and from town to town. Female university students have larger Facebook networks and spend more time on Facebook than male university students.

Resource Management in Mobile Cloud Computing
Andrei IONESCU 55
Mobile cloud computing is a major research topic in Information Technology & Communications. It integrates cloud computing, mobile computing and wireless networks. While mainly built on cloud computing, it has to operate using more heterogeneous resources with implications on how these resources are managed and used. Managing the resources of a mobile cloud is not a trivial task, involving vastly different architectures. The process is outside the scope of human users. Using the resources by the applications at both platform and software tiers come with its own challenges. This paper presents different approaches in use for managing cloud resources at infrastructure and platform levels.

Comparative Study on E-Government Indicators between Romania and the European Union
Otniel DIDRAGA, Claudiu BRANDAS 67
The development of e-government services increases the performance of the public sector by using ICT to deliver information to citizens, businesses, and public agencies. This article examines the development of e-government in Romania and compares it with the other EU countries. The indicators comparison is based on the seven e-government survey reports performed by the United Nations between 2003 and 2014 on 193 countries. The conceptual framework of the survey expresses a holistic view of the e-government development index (EGDI) and has three main dimensions: online services availability, telecommunication infrastructure, and human resource capacity. The UN global e-government ranking was intended to offer a performance rating of national governments relative to one another. Romania is ranked as a high-EGDI (between 0.5 and 0.75) country in 2014 worldwide with and EGDI value of 0.56315. Otherwise, among the EU countries, Romania is one of the low-ranked countries regarding the e-government development index in all the seven surveys. There are many opportunities for high-EGDI and middle-EGDI countries to continue e-government development. Considering EU strategies, investments in IT infrastructure, in education, and continuous transformation in online public services, there can be a considerable improvement of e-government in Romania and the other EU countries as well.

Illegal Oil Bunkering, Violence and Criminal Offences in Nigeria's Territorial Waters and the Niger Delta Environs: Proposing Extension of Informed Policymaking
Richard INGWE 77
While it illegal oil bunkering has gone on around the Niger Delta for about 30 years, it escalated more recently (2012 to present) thereby poses serious implications on many facets of in Nigeria economy, society, and environment. Government’s plan to eliminate it or drastically curb the crime has been hampered by inadequate knowledge of the scale of its occurrence in terms of the patterns expressed by its varying intensities or magnitude of its aspects over space, time, and structure. To achieve the objective of highlighting the recent escalation of illegal oil bunkering in the Niger Delta, this article examined issues helpful issues. It briefly reflected on recent studies of the phenomenal crime, its attendant geopolitical and geo-economic consequences on multinational economies and societies: Nigeria, UK, nations located close to the foregoing: European countries –on the one hand; Nigeria’s neighbors; Gulf of Guinea region- on the other. Other aspects that are briefly examined are: contextual explanation of Nigeria’s political economy, society, and related histories. Considering and comparing the recent estimation of the history of illegal oil bunkering of over 30 years with a recent study of the phenomenon over less than ten years (2002-2008), it is proposed that a study that extends the temporal scale of the analysis, preferably covering the entire life-span of the phenomenon is necessary. It is concluded that reckoning that the result of the shorter term spatial-temporal analyses study was robust, findings of the longer-term study promises to provide valuable information for strengthening public policy/programs for reducing oil theft in the region. Some aspects of the proposed study are outlined.

Internet of Things Based Systems for Food Safety Management
Mihai DOINEA, Cătălin BOJA, Lorena BATAGAN, Cristian TOMA, Marius POPA 87
The paper is highlighting the advantages of integrating technologies and digital standards in public politics for protecting consumer rights. Today’s globalization of food production chains, their extensive complexity and limitations arising from manual insertion and data processing of products information make it impossible for consumers the task of being informed in real-time. This obstacle can be overcome, and the current level of technology and low implementation costs allow full automation of this process. We propose a sensors network architecture based on Internet of Things (IoT) components, which is using autonomous embedded modules and radio identification tags (RFID) that will automatically collect data, covering the entire life cycle of the food product and all the factors that influence its chemical composition. This architecture offers consumers complete data about their food products and how their components were obtained.
