BEHAVIOURS OF GEN ZERS’ REPRESENATIVES ON SOCIAL MEDIA AS A BASIS FOR BUILDING ENTERPRISE-CUSTOMER RELATIONS

Building relationships with Generation Z on social media is becoming a challenge for present-day enterprises. The aim of the paper is to indicate the features of the activity of the representatives of generation Z in social media that enable the company to build relationships in order to achieve benefits.The study of Generation Z behaviour towards brands on social media is part of broader research conducted by the authors among students in Poland and Great Britain in 2020. The method used in the study was a survey, as part of which the CATI surveying technique was used. For analysis of the study material, descriptive statistics measures were used. The findings show which social networking portals are most often used by respondents of Generation Z, what benefits they then expect and what actions they perform most often when communicating with businesses on social media. Additionally, the strength of the relationships between the analysed variables and the respondent's gender was verified.

User-Review Oriented Social Recommender System for Event Planning

Recommender system is used to suggest product or topic based on user’s interest. Existing recommender system have focused on books, product, music etc. The problem in existing recommender system is that wedding/event based suggestions are not available. In the modern information era; storage, communication has been a challenge due to information veracity, volume, and velocity. Due to the constant and exponential growth of information, the utilization of information for context-oriented services is not productive. In this paper, a wedding planner recommender system framework has been proposed based on hybrid approach i.e., content based, collaborative filtering technique. The motive of proposed framework is to generate user-specific recommendations for different tasks related to the event specially wedding event, analyzed from the user comments on his social networking portal. Its main objective is to assist the user for organizing the events by suggesting specific vendors needed to arrange the event activities. Also, it would enhance the sales of location sensitive products in social commerce. The trial study conducted using a set of Facebook users is carried out to validate the proposed recommendation system framework. The success of the proposed framework is reported in terms of the level of user satisfaction achieved.

Identification of Disaster-Related Tweets Using Natural Language Processing: International Conference on Recent Trends in Artificial Intelligence, IOT, Smart Cities & Applications (ICAISC-2020)

In today’s world social media has become an integral part of life. Twitter is an American micro-blogging and social networking portal which provides the users a platform to post news, data and thoughts. Twitter has become an essential mode of communication medium during the occurrence of an emergency or disaster. The pervasiveness of smart phones and tablets enable people to pronounce and inform others of the occurrence of an emergency they are experiencing in real-time. This information regarding disasters propagated over the social media can save thousands of life by alerting others so that they can take evasive action. Many agencies are trying to programmatically analyze tweets and recognize disasters and emergencies. This kind of work can be beneficial to millions of people connected to the internet, who can be alerted in the case of an emergencies or disaster. But the real challenge lies in segregating the tweets trying to announce a disaster from the ones which are not related to a disaster. Twitter data is unstructured data, thus Natural Language Processing (NLP) has to be performed on the twitter data to classify them into classes –“Related to Disaster” and “Not related to Disaster”. The paper does a prediction on the test set created from the original data-set. It does an accuracy testing of the classifier model generated. This paper uses decision tree classification mechanism for building the classifier model and for making predictions.

Social Networks and Personal Security

The emergence of the Internet caused a significant simplification of interpersonal communication all over the world. True, the communication became fast, cheap and convenient and for people, who by nature are social beings, it enabled easy bonding, maintaining relationships and strengthened the feeling of belonging to one group or another. Along with development of the Internet social networking portals emerged becoming a popular means of communication and entertainment specifically dedicated to young people. The paper outlines the most important advantages and disadvantages of social networks especially with respect to security.

Adaptive video streaming for Technology-Enhanced Learning in workplaces

In recent years, the interest has been growing in video communication for training. Video clips have become an important learning resource, both within B2B distance training service offerings and the most popular social networking portals, such as YouTube™. In this scenario, however, the technical issue of how to proficiently deliver multimedia contents over heterogeneous wired or wireless networks remains a challenging aspect. This is mostly related to the varying characteristics of the underlying network technologies, as well as the requirement to comply with multiple platforms and end-user devices(such as desktops, laptops, tablets and smartphones). To provide a stable and uniform quality of experience to e-learners, the issue of monitoring the end-user and network context should be addressed and, leveraging on this information, the multimedia content should be dynamically adapted to match the device and network characteristics. This paper describes the Smart Multi-Channel Streaming Platform, a MPEG-DASH-based component enabling the delivery of full multichannel streaming services for media contents with a unified common standard, including on demand video clips based on the reference context. In this way, desired video quality adapts to the different Internet bandwidth and device capabilities, in order to keep a video playing. Next steps will include sensing the viewers and their surrounding environment to optimize streaming.

Sensor networks and systems for pervasive healthcare

Healthcare industry has transcended its traditional focus on medical treatment provision and life safety, having developed into a complex system of subsidiary services that are characterised by many technological applications. These applications are instrumental in guaranteeing the efficient, accurate, and low-cost execution of necessary operations. New medical technologies are currently being introduced at an ever-increasing pace in collaborative technologies and computer applications specifically designed for the purposes of healthcare, social networking and health portals. In particular, projects that focus on providing care, peer-to-peer networks, and sensor networks for pervasive healthcare merit particular attention. This paper highlights the digital revolution in healthcare by analysing the relevant literature and discussing the current scope of communication networks and innovative technologies, as well as their future needs and possibilities. A constructivist approach based on grounded theory methodology was applied to affirm the importance of sensor networking and pervasive healthcare in healthcare communication environments.

Outsourced Psychiatry: Remote Support

![Figure][1] Looking for help. An overcrowded mental hospital in Banda Aceh, Indonesia. CREDIT: G. MILLER/ SCIENCE In his News Focus story “Who needs psychiatrists?” (16 March, p. [1294][2]), G. Miller highlights the burgeoning psychiatric morbidities in regions left devastated by conflict. Social media can now provide access to an additional conduit of expertise, which can offer remote support and help in constructing virtual healthcare architecture in politically fragile nations. In Somaliland, with a population of 3.5 million people, United Kingdom–based organizations are already using social networking portals to support continuing medical education for interns ([ 1 ][3]) and to provide real-time mentoring for doctors managing challenging psychiatry cases. This support is crucial in a country with no psychiatrists in the public sector and in which chaining affected patients to the floor is common. With an unpredictable political climate limiting interventions by foreign agencies, social networks provide a practical means of offering regular, intercontinental support to doctors who would otherwise be isolated. Such technology could further be deployed to gather electronic healthcare workforce records, augment coordination of clinical trials, and monitor health economies. The disparities in medical capacity between Northern and Southern partners are already narrowing. If security and identity verification are safeguarded, social media could rapidly accelerate progress. 1. [↵][4]1. A. E. Finlayson 2. et al ., J. Telemed. Telecare 16, 181 (2010).

I-MOVE: towards the use of a mobile 3D GeoBrowser framework for urban mobility decision making

The field of Geographical Information Systems has assisted to a substantial growth within the last years, both in terms of quantity and quality of available data and at the same time, a number of standards for geospatial and location based services has been developed and adopted to improve the access to this information. As data becomes publicly available, the development of effective visualization applications, from simple virtual sight-seeing also known as geo-browsers to more complex solutions combining data with smart services, has opened the door for new opportunities to improve the general quality of life. Applications such as personal navigators, virtual globes, social networking and mobile review portals are only a small example set. This field, until recently restricted to high-end workstations and personal computers, is rapidly expanding to mobile devices to ensure seamless access to geospatial information to be used on the go. For this reason, one of the new challenges has become the visualisation of such information within these smartphones and their combination with their advanced hardware and connectivity equipment in order to create innovative smart services to improve the quality of life. This work illustrates the research work which has led to a lightweight three dimensional framework for geospatial visualization, running on Android enabled devices and how this technology has been used for intelligent urban mobility in the context of a European project as an example of its potential. The system makes use of hardware acceleration, complies with several standards typical of the geospatial domain, is customizable through a layer-based architecture and is used as a basis for daily intelligent multimodal routing. After a brief overview of the protocols and technologies adopted, the paper presents the system, the results of an extended test phase, some practical example of how the framework can be customized for a real urban mobility scenario, the problems tackled and the limitations to be faced.

The challenge of social networking in the field of environment and health

BackgroundThe fields of environment and health are both interdisciplinary and trans-disciplinary, and until recently had little engagement in social networking designed to cross disciplinary boundaries. The EU FP6 project HENVINET aimed to establish integrated social network and networking facilities for multiple stakeholders in environment and health. The underlying assumption is that increased social networking across disciplines and sectors will enhance the quality of both problem knowledge and problem solving, by facilitating interactions. Inter- and trans-disciplinary networks are considered useful for this purpose. This does not mean that such networks are easily organized, as openness to such cooperation and exchange is often difficult to ascertain.MethodsDifferent methods may enhance network building. Using a mixed method approach, a diversity of actions were used in order to investigate the main research question: which kind of social networking activities and structures can best support the objective of enhanced inter- and trans-disciplinary cooperation and exchange in the fields of environment and health. HENVINET applied interviews, a role playing session, a personal response system, a stakeholder workshop and a social networking portal as part of the process of building an interdisciplinary and trans-disciplinary network.ResultsThe interviews provided support for the specification of requirements for an interdisciplinary and trans-disciplinary network. The role playing session, the personal response system and the stakeholder workshop were assessed as useful tools in forming such network, by increasing the awareness by different disciplines of other’s positions. The social networking portal was particularly useful in delivering knowledge, but the role of the scientist in social networking is not yet clear.ConclusionsThe main challenge in the field of environment and health is not so much a lack of scientific problem knowledge, but rather the ability to effectively communicate, share and use available knowledge for policy making. Structured social network facilities can be useful by policy makers to engage with the research community. It is beneficial for scientists to be able to integrate the perspective of policy makers in the research agenda, and to assist in co-production of policy-relevant information. A diversity of methods need to be applied for network building: according to the fit-for-purpose-principle. It is useful to know which combination of methods and in which time frame produces the best results.Networking projects such as HENVINET are created not only for the benefit of the network itself, but also because the applying of the different methods is a learning tool for future network building. Finally, it is clear that the importance of specialized professionals in enabling effective communication between different groups should not be underestimated.

Application of social media in the environment and health professional community

The purpose of the EU FP6 funded coordination action HENVINET was to create a permanent network of environment and health professionals. The main outcome is a networking portal (http://www.henvinet.eu), based on the concepts of social media to support communication between professional stakeholders in the environment and health fields. Its aim is to enable sharing of relevant information in an innovative and interactive manner to eventually support policy making. A social networking tool is not necessarily a typical platform for communication in the professional context, or between scientists and decision-makers. The aim of this paper is to look upon the use of social media in relevant professional communities in the light of the HENVINET experience, and to reflect on the acceptance and usefulness of such a new approach.The portal was designed over the course of HENVINET through intensive interactions by a multi-disciplinary group, involving environmental as well as health scientists, but with only limited access to decision-makers’ opinions. After the social networking portal was launched, a recruitment campaign was run during the last six months of the project, taking every opportunity to present the portal and to get feedback from users. This feedback was used to improve the functionalities of the tool.Additionally, a feedback session was organized at the final event of the project, attended by over 50 professionals, about half of whom participated from the beginning in the entire HENVINET project. We have also compared the HENVINET portal with similar tools employed by other related communities, and made a literature-based survey on the use of social media for scientific communication.At the end of the project, the portal had more than 300 members with registered professional profile, over 10 topics and 15 discussion groups. The HENVINET consortium members were the most active group of users. The quality of the portal content was considered more important than having a large amount of information. To maintain the content, the majority of the participants declared their willingness to use their time, stating however that dedicated content providers would be also necessary.In theory, professionals see the value of such a tool, and are willing to contribute. Only time will tell if the tool is viable in the long run.

Showtime Thinks, Therefore I Am

In 2004 Showtime launched The L Word with a site that encouraged fans to login and chat about the show. Over time, they updated the site with all of the emergent bells-and-whistles: blogs, social networking, and Second Life portal. These new spaces simultaneously provided lesbians an expanded and easy-access online community and created a corporate-controlled space that spoke to Showtime’s own economic agenda. To partake in these new toys, fans were encouraged to define themselves in ways most conducive to the network’s sexual, economic, and gendered vision. Through an examination of the sites’ strict reins on identity construction as produced by its texts, interfaces, inclusions, and striking omissions, this article seeks to shed light on the subtle means by which corporate participation in and design of fan spaces can lead to fans (perhaps unwittingly) bending to corporate designs and playing on a field skewed to corporate rather than personal advantage.

Analysis of Portal for Social Network of IT Professionals

This paper presents an analysis of selected social networking portals for science, research and innovation as the first step in development of a portal for social network of IT professionals in the Czech Republic. First, actual portal implementations of four portals dedicated to scientific communities of researchers are analyzed, compared from the perspective of provided functions, layout and their interdependence and the main features are summarized. Then, the most important recommendations for the portal being developed are presented. The last part of the paper introduces two concepts of structured profiles - knowledge profile and scientific profile - that are proposed in order to precisely and explicitly express knowledge and scientific alignment of an IT professional. These two profiles will make it possible to search and compare IT specialists, their groups and projects or pair the users to the demands on the market. The paper concludes with a list of typical use cases where the profiles will be utilized.

Phenomenon of Nasza Klasa (Our Class) Polish Social Network Site

Introduction The design, implementation and success of the social networking portal Nasza-klasa (Our Class) is a model example of the 'rags to riches' ideal of an enterprise construed with no financial funding and no institutional support (neither from ASP/ISP corporations nor from central/local administration). Today, Nasza-klasa.pl ranks among top five Polish social community networking portals, not far behind Google.pl, Onet.pl and Wirtualna Polska (.pl), and followed by Allegro.pl - the biggest Polish Internet auction service. Nasza-klasa is visited monthly by more than 50% of Polish Internet users. There are several hundred of similar social networking services on global e-market. What are the reasons for this particular portal to reach such spectacular success on Polish e-market? First, it corresponds with the elementary need to communicate, a basic treat of human civilization (Barney, 2008; Castells, 2007; Mendes et al., 2004). Secondly, its authors were able to identify a very attractive business niche--after all, each individual has a certain history of social contacts in schooling communities (on elementary, secondary or university level). Thirdly, the portal under study offers a range of functionality and usability features that are well adapted to the needs and expectations of its users. Fourthly, the portal has strong foundation in the form of a constantly improved technological platform that offers stability, infallibility and excellent operational efficiency. Fifthly, Nasza-klasa has recorded a phenomenal, snowballed increase of unique registered users and visits, reaching the status of one of the most popular Polish sites within seven months. Incidentally, there is also a diversity of social graphs evolving on the site, illustrating various relations and ties between individual members on Nasza-klasa community. In general, those social graphs are carefully studied and analyzed by social scientists in such varied subjects as ethnology, sociology, psychology, economics, political studies, law, criminology (Boyd & Ellison, 2007). This particular aspect of Nasza-klasa operation is also emphasized in this study. Basic Information about Nasza-klasa In mid 2006, four students of Wroclaw University of Technology and University of Economics (Poland) devised and implemented a simple social networking portal addressed to members of present and past schooling and university communities. The prototype website came online in November, 2006 ('Nasza-klasa.pl,tour3, 2008d). The following three quarters saw a substantial increase in the number of registered users, mainly from Wroclaw and the Lower Silesia region. Site popularity was noticed by global capital investment funds. As a result, the portal obtained a significant financing support. A limited liability company was established under the name of Nasza Klasa. By the end of 2007, following the renown, press reports and word-of-mouth communication, the number of registered users doubled every month (Sukces naszej klasy, 2008). Consequently, at the turn of 2008, the snowball effect culminated in technological clogs that seriously affected website utility. To address this problem, company owners decided to incorporate another investor from the IT sector. The financial surge allowed to improve the service infrastructure; by the third quarter of 2008, technological and functional aspects of site operation and efficiency were stabilized ('Nasza-klasa.pl, 2008b). By the end of 2008, the company extended its organizational structure, updated their business model and provided new products and functionality features on the site. Table 1 presents results of a study (conducted in June, 2008) of most popular Polish websites, in terms of numbers of users, visits per month (as % of total Internet users), number of visits and average time spent viewing the site. As shown above, nasza-klasa.pl ranked fourth among the websites under study in terms of monthly percentage of users and total number of registered users (7. …

Community-driven ontology construction in social networking portals

The goal of the work presented here is to introduce community-driven ontology management as a new approach to ontology construction and demonstrate the added value to community portals of being community driven. The three main parts of the work are (i) the development of a framework allowing and motivating collaborative ontology construction and reuse for the end users (a person or a community), (ii) building a prototype on the basis of this specification, namely the People's portal, and (iii) the application of the developed infrastructure to scenarios in semantically-enhanced community portals with the involvement of real users. The development of the framework for community-driven ontology construction is aimed at enriching the established practices for ontology development and population with community-supporting features. The objective of community-driven ontology management is to provide the means and motivations for a large number of users to “weave” and adopt the Semantic Web. The People's portal infrastructure allows end users to define the content structure (i.e., develop ontologies), to populate ontologies, and to define the ways in which the content is managed on various semantically-enhanced community portals where the infrastructure is applied. An analysis of the functionalities of existing (Semantic) Web community environments and the empirical results obtained in this work are indicative of its feasibility and of the advantages of community-driven ontology construction. In practice, the communities were capable of introducing on the community portals such ontology items as Classes, Subclasses, Properties, Instances, ontology mappings, and of reusing these items afterwards.
