A presente dissertação investiga o quanto influencias situacionais, presentes nos sites de empresas do comércio eletrônico, impactam na intenção de recompra do consumidor online. Para tanto, um modelo teórico integrativo foi desenvolvido e investigado, baseado em uma revisão teórica dos principais estudos que pesquisam intenção de compra no e-commerce. Buscou-se o desenvolvimento de um modelo que proporcionasse uma explicação abrangente dos principais fatores advindos do contexto de compra nos sites que tivessem uma relação positiva com a satisfação e intenção de recompra do consumidor. Uma das grandes contribuições dessa dissertação é a identificação dos fatores presentes nos sites de empresas do e-commerce mais importantes no processo de decisão de compra do consumidor. Como contribuição teórica, esse modelo desenvolvido abrange além dos principais construtos que já estão sendo investigados nesta área de estudos (conteúdo, layout, risco percebido e diversão) construtos ainda não investigados em um mesmo modelo: Tipo de apelo utilizado na comunicação, Comunicação do preço, Tipo de manchete e Facilidade percebida na realização da transação. Além disso, investigou-se se a variável gerações de consumidores seria moderadora destas relações. Os dados desse estudo foram coletados a partir de uma amostra de 228 questionários válidos aplicados em consumidores que utilizam a Internet para realizar compras. O método de coleta de dados aplicado nesta pesquisa foi a pesquisa do tipo survey com questionários auto-administrados pela Internet. Para a análise de dados primários coletados, optou-se pelo uso do mínimo quadrado parcial (Partial Least Squares ou PLS) para a obtenção tanto das relações dos construtos independentes e dependentes, como também das relações existentes entre todos os construtos do modelo proposto. Resultados obtidos demonstram que a satisfação afeta diretamente a intenção de recompra do consumidor. Além disso, todos os construtos do modelo tiveram a hipótese sustentada, indicando influencias com magnitudes distintas, mas todas positivas. A variável gerações demonstrou moderar a relação de 4 dos 8 construtos da pesquisa. Destaca-se por fim que o modelo proposto permite a explicação de elevada proporção da variância total da intenção de recompra. / This project presents a study that investigates how recurrent online consumers are influenced by different aspects while shopping through websites (e-commerce). The author reviewed main international academic studies about buying intents through the internet, and then investigated and modeled an integrative survey, which could correlate both consumer satisfaction and rebuying intent with a series of factors related to the shopping experience. The main contribution of this paper is the identification of the most important factors on the online stores (e-retail) which positively impact the online shoppers, both, those already analyzed in many studies as content, layout, enjoyment and perceived risks, and some new constructs that have not been analyzed together as headlines, price/discount offers, advertisement appealing and easiness of browsing. Moreover, this paper also offered a perspective about whether and how these factors vary according do consumers\' generation. All data was extracted from an online self-administered survey with 330 consumers in São Paulo who declared being used to shopping goods through Internet. It came to a 228 valid respondents, whose responses were analyzed through the method of Partial Least Squares (PLS), in order to obtain both, the correlation of dependent and independent constructs, as well as the correlation among all factors analyzed within this study. The main outcome of this study is that online shoppers\' satisfaction strongly impacts their rebuying intention. Moreover, all the constructs present in this study have proved their positive impact on consumers rebuying intention, each factor varying in correlation strength, but all positive and statically proven. Besides that, the variable \'generation\' moderated 4 out of all 8 constructs presented in this study. Lastly, the proposed model statically explains higher proportion of total rebuying intention variance.

In these days we have more and more digitization of business content. The effort to reduce paper documents and replace them with digital/electronic form places increasing demands on the management of these documents and data/information in enterprises. With this kind of problem usually deal systems known as Enterprise Content Management. Main topic of this thesis is the implementation of MS SharePoint 2013. This thesis focuses its objectives on an analysis of the possibilities of using MS SharePoint, description of recommendations for the design of systems based on MS SharePoint and practical illustration of MS SharePoint implementation project in a specific organization. The first part of this thesis aims on the concept of Enterprise Content Management, MS SharePoint system performance and analyzing options how to deploy MS SharePoint into organizations. Based on this analysis, is further compared the coverage of functionality of MS SharePoint and specialized and robust ECM systems. The next part focuses on a description of the procedures that are recommended for the design and development of systems. In this part of the thesis is chosen an appropriate methodology for the development of information systems, which is used according to specific MS SharePoint implementation project within defined organization. Subsequently, the thesis analyzed the suitability of the methodology for the implementation of MS SharePoint and the proposed possible expansion of the selected methodology to fully meet the needs and specifics of MS SharePoint implementation projects. Subsequently, on the basis of these recommendations, there was made a draft of the MS SharePoint implementation project.

The thesis deals with web analytics of content based websites. Its primary aim is to design metrics of a web analysis and range of the metrics. This allows a proprietor of the content based websites to evaluate the state of the web and also its changes. The following is a practical example of handling website metrics and how to evaluate a web redesign with the help of these metrics. The first and second chapter lists literature of web analysis and specifies a purpose of the thesis and its target group. In the paragraphs that follow, I explain the theoretical starting-points and major concepts in further detail. In the third chapter I describe the main targets of content based websites because con-sequently defined metrics should reflect these targets and aim for them. Then I underline some specific problems of content based websites analysis. The fifth chapter forms the crux of this work. First, I define right metrics and then present the very design of metrics for analysis of content based websites. The proposed metrics describe interpretation of values, possibilities of segmentation and also relation to other metrics. In the fifth chapter there is an example of some metrics applied to real data of two content based websites with a description of how to work with these metrics.

Enabling access for people with disabilities, brings benefits to everyone, notonly people with disabilities. Therefore, accessibility is an important aspect to consider when designing a website. The purpose with this research paper is to explore how media agencies within the private sector that provides this service to others, work with web accessibility towards their customers and on their own websites. This report aims to examine media agencies’ level of knowledge  about web accessibility as well as their attitude and perception towards it. Furthermore, possible improvements of media agency’s websites will be investigated and suggested.   To answer our research questions, we have chosen a qualitative research approach. The method chosen is semi-structured interviews, these were conducted with three media agencies in Sweden. Additionally, an accessibility evaluation was performed of the media agencies websites with the accessibility tools AChecker and WAVE.  How much each media agency worked with web accessibility and WCAG differed, one of them did stand out among the others. The media agencies knowledge was broad, and their perception was comparable to the result from the accessibility evaluation of their website. The accessibility was high according to the accessibility tools, but there's room for improvements mainly when it comes to contrast issues, naming and labeling. In conclusion all media agencies are aware of web accessibility and Web Content Accessibility Guidelines which could be  seen on the results from the accessibility evaluation.

Web forms are one of the main points of user interaction on the internet. It is important that these forms are developed to be accessible to as many people as possible. The project aims to reduce the complexity for application developers when developing accessible web forms that conform to the Web Content Accessibility Guidelines (WCAG) using HTML and React. The result is a prototype library that creates an abstraction that application developers can use to build accessible web forms that conform to the WCAG.

Entretanto, a necessidade de trabalho manual por parte dos autores de conteúdo para a construção da sua base de diálogos não o torna muito atrativo para ser integrado a websites. Seria possível facilitar a criação de novos diálogos e automatizar a atualização dos mesmos usando como base os recursos disponibilizados pela Web Semântica para integrar o agente conversacional a um Sistema de Gerenciamento de Conteúdo Web (SGCW) de forma que seu conteúdo seja aproveitado. O trabalho aqui proposto descreve o modelo para utilização de informações de SGCW’s em agentes conversacionais com auxilio da web semântica, denominado Eduardo. O principal diferencial está na automatização da atualização dos diálogos, pois os mesmos são extraídos do SGCW para uma base de dados de triplas, que são consultadas para geração dos diálogos, caso haja alguma atualização na base do SGCW, basta refazer os procedimentos que já foram automatizados, para que os diálogos sejam atualizados, evitando assim o trabalho manual de edição dos arquivos escritos em linguagem AIML (Artificial Intelligence Markup Language). Foi desenvolvido um protótipo deste modelo, que permite a integração dinâmica de conteúdo com um Agente Conversacional. O protótipo foi avaliado quanto à capacidade de gerar as informações necessárias para os diálogos, acessando as páginas Web e representando seu conteúdo nos formatos RDFa e AIML. Em um segundo momento, ensaios de interação foram realizados com usuários nos componentes do Agente Conversacional, para avaliar sua funcionalidade, aceitação e demais aspectos uso. / A conversational agent is able to interact with users in natural language, imitating the dialogue held between humans. However, the need for manual labor by the authors content for the construction of dialogues base makes the not too attractive to be integrated into websites. It would be possible to facility the creation of new dialogues and automate the update them using as a basis the resources provided by the Semantic Web to integrate conversational agent to a Web Content Management System (WCMS) so that you content is used. The work proposed here describes the model for use of WCMS’s information in conversational agents with semantic web aid, called Eduardo. The main difference is in automating the update of dialogues, as they are extracted from WCMS for a triple database, which are referred to generation of dialogues, if there is any update on the basis WCMS, just redo the procedures that have been automated so that the dialogues are update, thus avoiding manual labor editing of files written in AIML (Artificial Intelligence Markup Language). It developed a prototype of this model which allows dynamic content integration with a conversational agent. The prototype was evaluated for ability to generate the information necessary for the dialogue, accessing the Web pages and their content representing in RDFa and AIML formats. In a second step, interaction assays were performed with users in the components of conversational agent to assess its functionality, acceptance and other aspects of use.

Advantages of cache cooperation on edge cache networks serving dynamic web content were studied. Design of cooperative edge cache grid a large-scale cooperative edge cache network for delivering highly dynamic web content with varying server update frequencies was presented. A cache clouds-based architecture was proposed to promote low-cost cache cooperation in cooperative edge cache grid. An Internet landmarks-based scheme, called selective landmarks-based server-distance sensitive clustering scheme, for grouping edge caches into cooperative clouds was presented. Dynamic hashing technique for efficient, load-balanced, and reliable documents lookups and updates was presented. Utility-based scheme for cooperative document placement in cache clouds was proposed. The proposed architecture and techniques were evaluated through trace-based simulations using both real-world and synthetic traces. Results showed that the proposed techniques provide significant performance benefits. A framework for automatically detecting cache-effective fragments in dynamic web pages was presented. Two types of fragments in web pages, namely, shared fragments and lifetime-personalization fragments were identified and formally defined. A hierarchical fragment-aware web page model called the augmented-fragment tree model was proposed. An efficient algorithm to detect maximal fragments that are shared among multiple documents was proposed. A practical algorithm for detecting fragments based on their lifetime and personalization characteristics was designed. The proposed framework and algorithms were evaluated through experiments on real web sites. The effect of adopting the detected fragments on web-caches and origin-servers is experimentally studied.

Was bedeutet Barrierefreiheit im Internet? Welche Elemente auf einer Website werden zur Barriere für Menschen mit Sehbehinderungen oder Blindheit? Was sind Barrieren für gehörlose Menschen und was sind Barrieren für körperlich eingeschränkte Menschen? Und wie können diese Barrieren erkannt und abgebaut werden? Welche Lösungsmöglichkeiten gibt es und mit welchem Aufwand sind diese umzusetzen? Die Arbeit zeigt am Beispiel einer Plattform für Studierende mit Behinderungen an der TU Dresden Barrieren im täglichen Umgang mit elektronischen Dienstleistungen für betroffene Nutzer auf. Dafür wird die Anwendung verschiedener anerkannter Evaluationsmethoden am Praxisobjekt demonstriert und mit echten Nutzer-Interviews ergänzt. Auf der Grundlage der erhobenen Daten wird das der Plattform zugrundeliegende Kontextszenario qualifiziert und erweitert und ein Redesign durchgeführt. Die erfolgreiche Anwendung und Umsetzung der Richtlinien für Barrierefreiheit und Gebrauchstauglichkeit wird anschließend dokumentiert und demonstriert.

E-handel i Sverige har varit aktuellt i många år, men till följd av coronapandemin har den svenska e-handeln ökat drastiskt. Det är därför av största vikt att alla, på lika villkor, har möjlighet att handla på internet. Sverige har flera lagar och regler för att förhindra diskriminering av personer med funktionsnedsättning, bland annat Lagen om tillgänglighet till digital offentlig service (DOS-lagen). Dock gäller lagen endast verksamheter inom offentlig förvaltning. I juni i år ska Europaparlamentets och rådets tillgänglighetsdirektiv bli svensk lag, vilket bland annat kommer att resultera i att svensk e-handel måste vara tillgänglig för alla.  Denna studie ämnar att undersöka tillgängligheten för synskadade inom svensk e-handel i dagsläget, innan denna lag har trätt i kraft. Detta har gjorts genom en etnografiskt förankrad studie, som syftar till att belysa  synskadade personers upplevelse av den svenska e-handeln. Därmed har en kvalitativ metod i form av semistrukturerade intervjuer tillämpats. Dessa intervjuer har genomförts med en teoretisk utgångspunkt i Web Content Accessibility Guidelines 2.1 samt utformats med en etnografisk utgångspunkt. Detta för att prioritera en renodlad redogörelse av upplevelsen hos respondenterna. Utöver dessa intervjuer, har en kvantitativ undersökning genomförts. Detta i form av en granskning av den svenska e-handeln. Syftet med detta har varit att kartlägga hur väl svensk e-handel lever upp till de uppsatta krav som Web Content Accessibility Guidelines 2.1 redogör för. Avsikten med denna del har varit att komplettera intervjumaterialet, snarare än att vara en betydande del.    Studiens slutsats återger att upplevelsen hos den berörda gruppen är nyanserad, och att både positiva och negativa erfarenheter har upplevts. Gällande det kompletterande materialet förefaller det tydligt att det finns utvecklingspotential inom svensk e-handel kopplat till tillgänglighetsfrågor, men också gällande tillvägagångssättet för testning av tillgänglighet på webbplatser.
