Resumo A recuperação da informação tem sido muito discutida dentro da Ciência da Informação ultimamente. A busca por informação de qualidade e compatível com a necessidade do usuário tornou-se objeto constante de pesquisa. A utilização da Internet como fonte de disseminação do conhecimento indicou novos modelos de armazenamento de informações, como os repositórios digitais, que têm sido utilizados em ambientes acadêmicos e de pesquisa como principal forma de autoarquivar e disseminar informação, porém com uma estrutura de informação que comporta melhor descrição dos recursos e consequentemente uma melhor recuperação da informação. Desta forma o objetivo deste trabalho é melhorar o processo de recuperação da informação, apresentando uma proposta de modelo estrutural no contexto da web semântica, abordando o uso de recursos da web 2.0 e web 3.0 em repositórios digitais, que permita recuperação semântica da informação, por meio da construção de uma camada de informação chamada Representação Iterativa. O presente estudo caracteriza-se como uma pesquisa descritiva e analítica, com base em análise documental, dividida em duas partes: a primeira, caracterizada pela observação direta não participativa de ferramentas que implementam repositórios digitais, assim como de repositórios digitais já instanciados, e a segunda, com característica exploratória, em que sugere um modelo inovador para repositórios, com a utilização de estruturas de representação do conhecimento e participação do usuário na construção de um vocabulário próprio de domínio. Através do modelo sugerido e proposto ─ Representação Iterativa ─ será possível adequar os repositórios digitais para que utilizem Folksonomia e também vocabulário controlado de domínio, de forma a gerar uma camada de informação iterativa, que possibilite retroalimentação da informação, além de recuperação semântica da informação, através do modelo estrutural desenhado para repositórios. O modelo sugerido resultou na efetivação da tese de que por meio da Representação Iterativa é possível estabelecer um processo de recuperação semântica da informação em repositórios digitais.Palavras-chave repositórios digitais; representação iterativa; folksonomia; folksonomia assistida; web semântica; recuperação da informação; ontologiaAbstract Information retrieval has been much discussed within Information Science lately. The search for quality information compatible with the users’ needs became the object of constant research.Using the Internet as a source of dissemination of knowledge has suggested new models of information storage, such as digital repositories, which have been used in academic research as the main form of autoarchiving and disseminating information, but with an information structure that suggests better descriptions of resources and hence better retrieval.Thus the objective is to improve the process of information retrieval, presenting a proposal for a structural model in the context of the semantic web, addressing the use of web 2.0 and web 3.0 in digital repositories, enabling semantic retrieval of information through building a data layer called Iterative Representation.The present study is characterized as descriptive and analytical, based on document analysis, divided into two parts: the first, characterized by direct observation of non-participatory tools that implement digital repositories, as well as digital repositories already instantiated, and the second with scanning feature, which suggests an innovative model for repositories, with the use of structures of knowledge representation and user participation in building a vocabulary domain. The model suggested and proposed ─ Iterative Representation ─ will allow to tailor the digital repositories using Folksonomy and also controlled vocabulary of the field in order to generate a data layer iterative, which allows feedback information, and semantic retrieval of information, through the structural model designed for repositories. The suggested model resulted in the formulation of the thesis that through Iterative Representation it is possible to establish a process of semantic retrieval of information in digital repositories.Keywords digital repositories; iterative representation; folksonomy; folksonomy assisted; semantic web; information retrieval; ontology

Semantic Web technology is not new as most of us contemplate; it has evolved over the years. Linked Data web terminology is the name set recently to the Semantic Web. Semantic Web is a continuation of Web 2.0 and it is to replace existing technologies. It is built on Natural Language processing and provides solutions to most of the prevailing issues. Web 3.0 is the version of Semantic Web caters to the information needs of half of the population on earth. This paper links two important current concerns, the security of information and enforced online education due to COVID-19 with Semantic Web. The Steganography requirement for the Semantic web is discussed elaborately, even though encryption is applied which is inadequate in providing protection. Web 2.0 issues concerning online education and semantic Web solutions have been discussed. An extensive literature survey has been conducted related to the architecture of Web 3.0, detailed history of online education, and Security architecture. Finally, Semantic Web is here to stay and data hiding along with encryption makes it robust.

After having shifted from Web 1.0 to Web 2.0, scientists welcome the advent of Web 3.0, an environment where meaning is added to data. While in the Semantic Web people are no longer users, but part of the emerging applications, producers, subjects and beneficiaries of the Big Data, however, opaque processing of personal data poses tremendous risks and dangers for individuals. Given the new era of Big Data this paper studies firms’ purposes and practices to detect some emerging privacy risks. Moreover, theories that deal with social networks are examined to conclude that, even if people state that they value their privacy, however, they often disclose a huge volume of personal information. Taking into account that today’s European concept of privacy is conceptualized in negative terms this paper also proposes the implementation of trust and loyalty into the privacy concept through flexible fiduciary laws. Furthermore, data portability is discussed to detect its potential as a strategic feature, a key tool that will enhance trust. Finally, further scenarios and proposals are submitted, in our attempt to answer the question whether the European concept of privacy could be re-shaped for the benefit of individuals.

Digital public sphere is immersed in the present conjuncture of accelerated transformation and probable rupture, which certainly will affect the way we exercise our citizenship in contemporary times. This social and political tsunami is partly based on the change of paradigm of Web 2.0 or Social Web to Web 3.0 or Semantic Web. To clarify such a process, this paper discusses some of the key issues and theoretical positions on public space, from seminal Habermas’s perspective to new problematics raised by the networked society. The author suggests the construction of a Sociological Ontology of Social and Semantic Web, based on a Semantic-Logical Sociology and Methodology. These procedures are applied through the analysis and hermeneutics of a Wikipedia page entitled ‘Web 2.0’, where sociological experimental tools are used, as Semantic-Logical fields, trees and networks, central and peripheral concepts, and trichotomies.

Web 2.0 delivers the information which is then displayed in human readable content, omitting the crucial information which can be drawn from the data by the applications. Web 3.0 or semantic web is an extension to the current web, with an ambition to determine the drawbacks of the current web. The semantic web has already proven its influence in several communities around the globe, such as social media, music industry, healthcare domain, online blogs or articles, etc.; Among the several tools and technologies, ontologies or vocabularies are the foundation pillar for the semantic web. In this paper, the developed system aims at improving the collaboration and academic relations among staff which is directly related to our education community by providing a better networking platform which lets the agents discuss their achievements, titles, domain interests, and various other activities. Results have been analyzed to show how new facts, information can be implied from the presented knowledge of several agents and help generate a relationship graph by utilizing various semantic tools. The system discussed in this paper processes all the information in a format which can be understood by both humans and the machines, to interpret the underlying meaning about it and provide effective results.

The aim of this work is to help cultural web application developers to benefit from the latest technological achievements in Web research. The authors introduce a 3-tier architecture that combines Web 2.0 principles, especially those that focus on usability, community and collaboration, with the powerful Semantic Web infrastructure, which facilitates the information sharing among applications. Moreover, they present a development methodology, based on this architecture, especially tailored for the cultural heritage domain. Cultural developers can exploit this architecture and methodology in order to construct web2.0-powered cultural applications with rich-content and responsive user-interface. Furthermore, they outline some indicative applications in order to illustrate the features of the proposed architecture and prove that it can be applied today and support modern cultural web applications.

While the term Web 2.0 is used to describe the current trend in the use of Web technologies, the term Web 3.0 is used to describe the next generation Web, which will combine Semantic Web technologies, Web 2.0 principles, and artificial intelligence. Towards this perspective, in this work we introduce a 3-tier architecture for Web applications that will fit into the Web 3.0 definition. We present the fundamental features of this architecture, its components, and their interaction, as well as the current technological limitations. Furthermore, some indicative application scenarios are outlined in order to illustrate the features of the proposed architecture. The aim of this architecture is to be a step towards supporting the development of intelligent Semantic Web applications of the near future, as well as supporting the user collaboration and community-driven evolution of these applications.

Web 3.0 ile anlamsal ağ yapısına dönüşen web teknolojisi etkileşim, dinamiklik, çoklu ortam gibi özelliklerin ötesine geçerek makinelerin birbiriyle iletişime geçtiği, kişiselleştirilmiş algoritmaların küresel pazar için daha çok kâr oluşturacağı ticari çıkarlar üzerine kurulu bir sistemdir. Anlamsal ağ, seçim özgürlüğünün olduğunu düşündüğümüz aslında bize dayatılan içeriğe ve reklama maruz kaldığımız bir web teknolojisidir. Web 2.0 ile kullanıcılarını pasif durumdan empatik işçiye dönüştüren web teknolojisi, semantic web ile de metalaştırmıştır. Ürün ya da hizmet alışverişinden kişilerin verilerinin alınıp satıldığı bir sektör ile gözetim kapitalizmi oluşturulmuştur. Ekonomik bir unsur olan sosyal ağ uygulamaları, daha çok kâr için adeta insan matriksi oluşturarak tutum ve davranışlarını etkilemektedir. “Bağlı mıyız yoksa bağımlı mıyız” diye sorguladığımız bu günlerde, materyal tasarımlarının etkisiyle insanları kendisine kilitleyen sosyal ağ uygulamaları, kişinin dopamin salgılamasına etki ederek ekrana bakma sürelerini uzatmıştır. Markalar için oldukça etkili reklam fırsatları oluşturularak özellikle hedef kitleleri ile ilgili verilerin toplanması, yorumlanması gibi süreçlerde doğrudan müşteriye ulaşarak onların satın alma davranışlarını etkilemekte ve çeşitli imkânlar sağlaması nedeniyle kişiselleştirilmiş web teknolojisi yaygın bir şekilde tercih edilmektedir. Bu kapsamda çalışmanın konusunu internet kullanıcılarının anlamsal ağ ile metalaştırılması ve kişiselleştirilmiş içeriklerle ilgili reklam iletisi alma durumu oluşturmaktadır. Araştırmanın amacı ise katılımcıların semantic web’e yönelik tutumlarının araştırılarak, alana yeni bir katkıda bulunmaktır. Çalışmada Survey araştırması yöntemi kullanılmıştır. Online anket tekniğinden yararlanılmış ve araştırmaya 147 denek katılmıştır. Araştırmanın evreni internet kullanıcıları olarak belirlenmiştir. Örneklemi ise 18 yaşından büyük kişiler olarak seçilmiştir. Gerçekleştirilen analizlere göre anlamsal ağın ne ifade ettiği bilenmemektedir. Fakat katılımcılar bilinçli ya da bilinçsiz olarak kişiselleştirilmiş ağın etkilerini hissetmekte ve onu deneyimlemektedirler. Ayrıca kişiselleştirilmiş reklam içeriklerinin katılımcıların kısmen satın alma davranışlarını etkilediği sonucuna ulaşılmıştır.

A foreseeable incarnation of Web 3.0 could inherit machine understandability from the Semantic Web and collaborative editing from Web 2.0 applications. We review the research and development trends, which are getting, today, Web nearer to such an incarnation. We present semantic wikis, microformats, and the so-called “lowercase semantic web”; they are the main approaches at closing the technological gap between content authors and Semantic Web technologies. We discuss a too often neglected aspect of the associated technologies, namely how much they adhere to the wiki philosophy of open editing: is there an intrinsic incompatibility between semantic rich content and unconstrained editing? We argue that the answer to this question can be “no,” provided that a few, yet relevant, shortcomings of current Web technologies will be fixed soon.
