Twitter Spam Detection using Pre-trained Model

In the age of technology social media platform is becoming a great companion for expressing the thoughts, information, and opinion. It became the powerful tool for every person who wants to expand their networks of people beyond the physical boundation. We are living at that age where various categories of social media platform available according to work needed, it may be Facebook, LinkedIn, WhatsApp or Twitter. We are focusing our work on Twitter, It is also known as microblogging site which provides service to express the opinion in limited words. As the popularity of twitter is growing day by day users are joining the platform very fast, as it happens another side many spammers are also taking undue advantages of this platform, for any social media platform it is very important to maintain the secure, safer and trustworthy environment for their legitimate users. Twitter spams are more harmful than e-mail spam because of their higher clickthrough rate, as in the social network if someone trusted some spam a genuine post than it is higher chance that the persons in the network might also trust on that spam post and may click on it. There are plenty of methods available to handle the task of twitter spam detection problem, we are solving this problem of twitter spam at tweet level.Pre-trained models are some breakthrough in the journey of machine learning and natural language processing after their advancement they are of great help. Here we are using Bidirectional Encoder Representation from Transformer (BERT) model to solve the problem as our task is to solve the problem of imbalance dataset as well as the multilingual dataset, BERT makes a clear distinction in this type of task, the main advantage of this type’s model is that we don’t have to collect millions of data for better performance of the machine learning model.

The Impact of Technology on People with Autism Spectrum Disorder: A Systematic Literature Review.

People with autism spectrum disorder (ASD) tend to enjoy themselves and be engaged when interacting with computers, as these interactions occur in a safe and trustworthy environment. In this paper, we present a systematic literature review on the state of the research on the use of technology to teach people with ASD. We reviewed 94 studies that show how the use of technology in educational contexts helps people with ASD develop several skills, how these approaches consider aspects of user experience, usability and accessibility, and how game elements are used to enrich learning environments. This systematic literature review shows that the development and evaluation of systems and applications for users with ASD is very promising. The use of technological advancements such as virtual agents, artificial intelligence, virtual reality, and augmented reality undoubtedly provides a comfortable environment that promotes constant learning for people with ASD.

Unsilencing the silent South African HIV-positive RESEARCHER: An HIV-positive researcher’s reflection on negotiating insider- outsider positionalities whilst conducting a HIV study in eThekwini, KwaZulu-Natal, South Africa

The research study that informed this article’s discussion, critically interrogates an HIV-infected research team’s positionality whilst conducting a mixed-methods’ study on HIV-positive patients’ experiences of the public ART programme at four ARV clinics in KwaZulu-Natal, South Africa. It primarily utilises the principal investigator’s (PI) narrative to explore insider/outsider positionality, reflexivity, bracketing and participatory action research through exposure of feelings, emotions, challenges, engagements, relationships and observations. The fluid positionality of the HIV-positive research team presented both challenges and opportunities. However, the opportunities for more HIV-infected researchers to engage in HIV-related research to assist with destigmatising HIV, close research gaps and the creation of a trustworthy research environment to achieve an ethical and reliable health science study, far outweigh the challenges. Further, such research can improve patients’ support and healthcare, healthcare workers’ perceptions of patients, and provide a guide for policymakers to better understand the recipients of HIV policies. Lastly, the term ‘HIV reflexivity’ is coined as a result.

A Multidimensional Trust Evaluation Framework for Online Social Networks Based on Machine Learning

Due to the openness of online social networks (OSNs), they have become the most popular platforms for people to communicate with others in the expectation of sharing their opinions in a trustworthy environment. However, individuals are often exposed to a wide range of risks posed by malicious users who spread various fake information to achieve their vicious goals, which makes the concept of trust a vital issue. Most of the existing research attempts to construct a trust network among users, whereas only a few studies pay attention to analyzing their features. In this paper, we propose a trust evaluation framework based on machine learning to facilitate human decision making by extensively considering multiple trust-related user features and criteria. We first divide user features into four groups according to the empirical analysis, including profile-based features, behavior-based features, feedback-based features, and link-based features. Then, we design a lightweight feature selection approach to evaluate the effectiveness of every single feature and find out the optimal combination of features from users' online records. We formalize trust analysis as a classification problem to simplify the verification process. We compare the performance of our features with four other feature sets proposed in the existing research. Moreover, four traditional trust evaluation methods are employed to compare with our machine learning based methods. Experiments conducted on a real-world dataset show that the overall performance of our features and methods is superior to the other existing features and traditional approaches.

Q-DWSO: hybrid approach for QoS-aware dynamic web services orchestration

Many complex business-applications require the composition of tasks invoking multiple web services. The complexity of a composition process increases when a composition needs dynamic functionalities. Web services (WSs) of different service providers can be functionally identical, but have varying Quality of Service (QoS) attributes. A QoS optimisation is thus required at every stage in a composite web service (CWS). Maximising the overall utility functions are the need at both, component and composition levels. Local (task level) or global (composition using tasks in CWS) optimisation is currently used approach during the composition from the tasks. The present paper proposes a hybrid approach using the local as well as global optimisations. While local optimisation ensures the composition from the WSs in the trustworthy environment, the global optimisation satisfies the QoS constraints at the global level. The approach uses a hybrid orchestration structure. It maximises overall utility functions and reduces computational time related complexity.

Impact of knowledge management enablers on knowledge sharing

PurposeThe purpose of this paper is to examine the mediating role of trust in the relationship between knowledge management enablers (i.e. top management support, organizational culture, knowledge management system quality, and openness in communication) on knowledge sharing in small and medium enterprises (SMEs) in Pakistan.Design/methodology/approachThe study was conducted through self-administered survey of employees of SMEs in Pakistan. Correlation, Baron and Kenny approach (causal steps approach) and PROCESS Macro (normal test theory) developed by Hayes were used to find out the direct and indirect effects of trust among knowledge management enablers and knowledge sharing.FindingsThe results have shown that trust of employees at SMEs was developed through knowledge management enablers which promote knowledge sharing. Therefore, the relationship between knowledge management enablers, trust, and knowledge sharing is positive.Research limitations/implicationsThe current study only considered the single aspect of knowledge management system, i.e. knowledge sharing; some other aspects of knowledge management system such as knowledge creation and knowledge utilization can be used for future studies at SMEs sector.Practical implicationsThe mediation of trust between top management support, culture, openness in communication, and knowledge sharing provided that trustworthy relationships between the members of an organization would lead to enhance the knowledge sharing activities. In order to promote the knowledge sharing attitudes within the organization, the managers should consider knowledge management enablers (top management support, organizational culture, and openness in communication) along with trustworthy environment as an energetic force for the development of knowledge management systems.Originality/valueThe study confirmed the mediating effect of trust between the relationships of top management support, organizational culture, openness in communication, and knowledge sharing, while there is a partial mediating role of trust between knowledge management system quality and knowledge sharing.

Information Governance in Dynamic Networked Business Process Management

Competition in today’s globalized markets forces organizations to collaborate within dynamic business networks to provide mass-customized integrated solutions for customers. The collaboration within dynamic business networks necessitates forming dynamic networked business processes (DNBPs). Networked business processes need to be supported by high quality information that is exchanged in a trustworthy environment. Information governance (IG) is described as a holistic approach to different mechanisms that support high quality and secure information exchanges. However, dynamism of networked business processes causes IG issues like unsecured information access and low quality information products to emerge. In this paper, a comprehensive list of the IG issues in DNBPs is identified through structured steps. The identified IG issues are characterized within four main categories, respectively, information product quality, information service quality, information security, and metadata issues. For the evaluation of the practical significance of the identified IG issues, a case study is conducted in a business network that provides mobility solutions. In this way, the paper closes the gap between studies on IG, which have mostly concentrated on IG within the borders of a single organization or IG in stable business networks, and studies on dynamic business networks, which have addressed the formation of dynamic inter-organizational interactions without paying rigorous attention to information artefacts that are exchanged.

Does Gender Equality Promote Social Trust? An Empirical Analysis

Summary Fairness is an important factor that promotes social trust by reducing social heterogeneity and gaps between people. This paper empirically investigates whether gender equality—fairness between men and women—increases social trust by analyzing a global sample from the World Values Survey. The findings show that gender discriminatory values negatively affect the trust levels of both men and women, while women’s status in labor, education, and political dimensions is not a significant determinant. These results indicate that values regarding gender equality (fair values) are arguably more important to social trust than the actual socioeconomic conditions of women (fair conditions). Furthermore, the effect of gender equality varies across countries with different levels of gender endowments. Gender-related values are an important factor of social trust in countries where gender equality is relatively high, but its effect is minimal in countries with greater gender discrimination. This finding implies that fairness is a more essential social value in countries where equality is already established. Finally, the empirical investigation finds a stronger effect of gender equality on men than on women—especially in high gender-equal countries. This result contradicts the initial expectation that gender equality influences women more significantly and thus, the effect should be larger for them. A possible explanation for this result is that gender equality establishes a more trustworthy environment of men which increases their trust level more.

Community engagement: The ‘last mile’ challenge for European research e-infrastructures

Europe is building its Open Science Cloud; a set of robust and interoperable e-infrastructures with the capacity to provide data and computational solutions through cloud-based services. The development and sustainable operation of such e-infrastructures are at the forefront of European funding priorities. The research community, however, is still reluctant to engage at the scale required to signal a Europe-wide change in the mode of operation of scientific practices. The striking differences in uptake rates between researchers from different scientific domains indicate that communities do not equally share the benefits of the above European investments. We highlight the need to support research communities in organically engaging with the European Open Science Cloud through the development of trustworthy and interoperable Virtual Research Environments. These domain-specific solutions can support communities in gradually bridging technical and socio-cultural gaps between traditional and open digital science practice, better diffusing the benefits of European e-infrastructures.

A Hybrid Cryptographic Technique for Secured Authentication in Cloud Computing

The cloud infrastructure development and service distribution is a complex task. A number of members are contributing in this task such as clients, intermediate service providers and the data centre owners. In such kind of scenarios the infrastructure providers are distribute their service by the help of intermediate servers or vendors. Due to this the quality of service, trust, security and privacy of the data and their owner is a key issue of management. Therefore a secure and trust worthy environment is need to be created for improving the data owner trust on the primary service providers. In this presented work the key focus of the study is placed on the server security and the user trust management. Therefore the proposed technique involves the development of secure cryptographic cloud. The cryptographic cloud is implemented with the help of a hybrid cryptographic technique which involve the Data Encryption standard (DES) encryption technique for ciphering data and for key exchange the Diffie Hellman (DH) algorithm is implemented. Further for more improved security the integrity check is also implemented with the help of Message Digest (MD) 5 hash generation algorithm. After implementation of the cryptographic cloud the trust management between the primary service provider and brokers are need to implement for managing the end client trust on primary service provider. Therefore a two factor trust computation technique is proposed using the server rating and the number of request failures. This trust value is help to regulate the quality of service offered by the primary service provider. The implementation of the proposed technique is performed with the help of JAVA technology and their performance is reported with the help of space and time complexity. According to the experimental results the proposed technique offers more secure environment and with less computational overheads.

Customer loyalty guidelines for independent financial advisers in South Africa

Orientation: Independent financial advisers in South Africa can make a valuable contribution to the financial well-being of the country’s citizens and, through sound financial planning and education, assist them in becoming financially independent.Research purpose: The purpose of this study was to develop guidelines for creating customer loyalty towards independent financial advisers in South Africa.Motivation: To succeed, financial advisers need to build good relationships with clients and ensure they remain loyal to them in the long term.Research design, approach and method: A convenience non-probability sampling technique was applied, and altogether 262 self-administered questionnaires were completed and used in the analysis. Descriptive and standard multiple regression analysis and the one-way analysis of variance (ANOVA) technique were used to test four hypotheses formulated for the study.Main findings: Relationship commitment must be established in a trustworthy environment, regardless of the type of province where the business is operated.Practical/managerial implications: In urban provinces (such as Gauteng) both trusting relationships and commitment could lead to customer loyalty; in semi-urban provinces (such as North-West) only the commitment variable might do so. Independent financial advisers in both provinces should explore additional factors that could foster customer loyalty.Contributions: The research findings of this study challenge the seminal work of Morgan and Hunt (1994) by establishing that in South Africa, the extent to which trust and commitment predicts customer loyalty is specific to both industrial and geographical location. This study further provides customer loyalty guidelines for independent financial advisers in South Africa.

Healthcare plans and consumer perceptions of healthcare institutions.

This study evaluates the effect of healthcare insurance plans on consumer perception of trust in a healthcare institution, and the mediating effect of trust on consumer loyalty towards an institution. The study was conducted at a healthcare institution in Colombia where a total of 841 patients responded to a questionnaire. A structural equation model shows that individuals who have a pre-paid healthcare plan have a stronger evaluation of trust compared to those who hold a regulated healthcare plan (i.e., subsidized and contributory plans). In turn, trust positively predicts consumers' loyalty towards an institution. The relationship between the patients' healthcare plans and their degree of loyalty towards healthcare institutions is completely mediated by their perception of trust towards the institution. A greater perception of trust is explained by having a medical plan that provides consumers with more flexibility, allowing them to select their health provider at a premium price. Although health institutions do not control healthcare regimes, these affect consumers' trust in their service. Institutions cannot modify characteristics of the regime, but they can promote a trustworthy environment to strengthen consumers' loyalty to the institution.

Urban Vision – A Static Destination or a Dynamic Process?

Abstract Globalization forces cities and areas to compete with each other to attract talented and motivated inhabitants. In an attempt to differentiate in the competitive market, city officials are creating urban visions by collaborating with a variety of stakeholders. However, every stakeholder perceives the visions differently, and the implementation processes are slow. The capability to update the vision can decrease the uncertainty in the success of the overall implemented solution. Therefore, this paper strives to increase understanding of the processes behind areal vision creation and investigates the effects to the resulting area. The paper presents a single intrinsic case study and takes a qualitative approach by analyzing nine thematic interviews on Suurpelto case in Espoo, Finland. The interviewees represent different stakeholders of both vision building and implementation phases and of both private and public sector. The case represents a situation where economical recession radically changed the operational environment and an essential stakeholder backed up from the project during the operational process changing the dynamics and the implementation potential of the original vision. The results indicate that trust between all the stakeholders through out the vision and implementation phases is essential for succeeding in a project but also a means of gaining trust of the inhabitants. For the practitioners, this implies that more attention should be paid on trust building issues between the different stakeholders throughout the vision building process in order to create trustworthy environments for the potential inhabitants, businesses and other prospects. Potential future research could focus on analyzing the vision progress in a more detailed manner, especially from the perspective of inhabitants of the area.

A P2P-Based Infrastructure for Adaptive Trustworthy and Efficient Communication in Wide-Area Distributed Systems

Tremendous advances in pervasive networking have enabled wide-area distributed systems to connect distributed resources or users such as corporate data centers and high-performance computing centers. These distributed pervasive systems take advantage of resources and enhance collaborations worldwide. However, due to lack of central management, they are severely threatened by a variety of malicious users in today's Internet. Current reputation- and anonymity-based technologies for node communication enhance system trustworthiness. However, most of these technologies gain trustworthiness at the cost of efficiency degradation. This paper presents a P2P-based infrastructure for trustworthy and efficient node communication in wide-area distributed systems. It jointly addresses trustworthiness and efficiency in its operation in order to meet the high-performance requirements of a diversified wealth of distributed pervasive applications. The infrastructure includes two policies: trust/efficiency-oriented request routing and trust-based adaptive anonymous response forwarding. This infrastructure not only offers a trustworthy environment with anonymous communication but also enhances overall system efficiency through harmonious trustworthiness and efficiency trade-offs. Experimental results from simulations and the real-world PlanetLab testbed show the superior performance of the P2P-based infrastructure in achieving both high trustworthiness and high efficiency in comparison to other related approaches.

Digital identity: Transforming GCC economies

Governments and businesses alike are coming to understand that national and global economies should use the Internet as a medium for innovation and economic growth. A critical component that has been left to service providers to establish and manage is that of digital identities of online clients and customers. Lack of regulation and effective methods of management has resulted in greater concerns over privacy, security, and productivity in online environments, thus hindering the development and use of the full potential of the Internet. This paper attempts to explore the role of a government initiated digital identity management system in supporting the creation of a stronger digital economy. The author provides an overview of the identity management infrastructure development initiatives in Gulf Cooperation Council countries and briefly examines their potential to revolutionize and transform existing economic models. The author argues that the new smart identity cards produced in these countries may serve as secure tokens that connect digital and physical identity, create trustworthy environments, and strengthen confidence in online transactions critical to the growth of the digital economy.

Digital Preservation and Authentic Legal Information

Writing and researching about the permanence of digital documents is a quizzical, self-referential activity. I set out to uncover approaches to the problems facing the longevity of authentic legal information. How did I do this? Primarily, I accessed and read electronic documents. My exercise here might very well suffer the same issues raised in the information science and legal literature. Faulty, inconsistent, and potentially inauthentic electronic databases may unduly – however subtly – shade my analysis. For what I’m doing here – a student’s attempt to add to an academic discourse – I’m pretty unconcernedThe subject of my focus, however, is an entirely different matter. The law has consequences large and small. Legal information, whether in the form of publications or records, impacts our lives in concrete ways. Criminal codes convict. Election rules elect. Construction standards keep roofs from falling in. The law is important. Further, although “the law” is a complex political, social, and interpersonal construct, it is ultimately expressed through words.Digital files distributed through the internet present problems to information generally, and to the law specifically. If we take a skeptical view – as I think we should – how do I know that words I read are the words that were written? This paper is a meditation on that question and search for an answer.Part I describes the issues of authenticity as they’re discussed in the English-language library and information science literature. Part II describes the importance of authenticity to the law. Finally, Part III describes the potential dangers if we fail to adequately address preserving authentic legal information. At each step along the way, we’ll see the need for libraries and archives to take an active role in the creation of documents and foster a trustworthy informational environment.
