Making 'The Daily Me': Technology, economics and habit in the mainstream assimilation of personalized news
The mechanisms of personalization deployed by news websites are resulting in an increasing number of editorial decisions being taken by computer algorithms — many of which are under the control of external companies — and by end users. Despite its prevalence, personalization has yet to be addressed fully by the journalism studies literature. This study defines personalization as a distinct form of interactivity and classifies its explicit and implicit forms. Using this taxonomy, it surveys the use of personalization at 11 national news websites in the UK and USA. Research interviews bring a qualitative dimension to the analysis, acknowledging the influence that institutional contexts and journalists’ attitudes have on the adoption of technology. The study shows how: personalization informs debates on news consumption, content diversity, and the economic context for journalism; and how it challenges the continuing relevance of established theories of journalistic gate-keeping
Mapping web personal learning environments
A recent trend in web development is to build platforms which are carefully designed to host a plurality of software components (sometimes called widgets or plugins) which can be organized or combined (mashed-up) at user's convenience to create personalized environments. The same holds true for the web development of educational applications. The degree of personalization can depend on the role of users such as in traditional virtual learning environment, where the components are chosen by a teacher in the context of a course. Or, it can be more opened as in a so-called personalized learning environment (PLE). It now exists a wide array of available web platforms exhibiting different functionalities but all built on the same concept of aggregating components together to support different tasks and scenarios. There is now an overlap between the development of PLE and the more generic developments in web 2.0 applications such as social network sites. This article shows that 6 more or less independent dimensions allow to map the functionalities of these platforms: the screen dimensionmaps the visual integration, the data dimension maps the portability of data, the temporal dimension maps the coupling between participants, the social dimension maps the grouping of users, the activity dimension maps the structuring of end users–interactions with the environment, and the runtime dimensionmaps the flexibility in accessing the system from different end points. Finally these dimensions are used to compare 6 familiar Web platforms which could potentially be used in the construction of a PLE
Language design for a personal learning environment design language
Approaching technology-enhanced learning from the perspective of a learner, we foster the idea of learning environment design, learner interactions, and tool interoperability. In this paper, we shortly summarize the motivation for our personal learning environment approach and describe the development of a domain-specific language for this purpose as well as its realization in practice. Consequently, we examine our learning environment design language according to its lexis and syntax, the semantics behind it, and pragmatical aspects within a first prototypic implementation. Finally, we discuss strengths, problematic aspects, and open issues of our approach
A mobile tour guide app for sustainable tourism
Portugal has had a flourishing tourism sector for the past few years. In fact, Portugal’s tourism
boom has made the industry one of the biggest contributors to the national economy and the
largest employer. In the year 2019, Portugal had a total of 27 million tourists, surpassing once
again the record established in the previous year. However, tourism also brings a series of
unintended negative side effects, such as overcrowding. The Santa Maria Maior historic district
in Lisbon is being particularly affected by this problem.
The work undertaken in this dissertation is part of the Sustainable Tourism Crowding project,
that aims to mitigate the overcrowding phenomenon in this district, by fostering a balanced
distribution of visitors while promoting the visitation of sustainable points of interest. This
dissertation focuses on developing a mobile app prototype targeted at tourists, through which
these sustainable walking tour recommendations can be delivered.
To validate the functional requirements of the prototype, more specifically the trip creation
process, a series of unit tests, integration tests, and manual tests were developed. To evaluate
the usability of the prototype, a user-centered approach was adopted during the design stage,
in which two usability techniques were conducted with members of ISCTE’s research center
ISTAR and partners from the Junta de Freguesia de Santa Maria Maior, that guided and validated
the decisions made.
The achieved prototype contains mechanisms for measuring tourists’ adherence to the
recommended tours using the Dynamic Time Warping algorithm, which raises new research
opportunities on tourists’ behaviour.O desenvolvimento prĂłspero do setor turĂstico em Portugal nos Ăşltimos anos fez da indĂşstria
um dos maiores contribuintes para a economia nacional e o maior empregador do paĂs. No ano
de 2019, Portugal recebeu um total de 27 milhões de turistas, ultrapassando uma vez mais uma
vez o recorde estabelecido no ano anterior. No entanto, o turismo traz também uma série de
efeitos secundários negativos não intencionais, tais como overcrowding. A freguesia histórica de
Santa Maria Maior em Lisboa está a ser particularmente afetada por este problema.
O trabalho desenvolvido nesta dissertação faz parte do projeto de pesquisa Sustainable
Tourism Crowding, que visa mitigar o fenĂłmeno de overcrowding nesta freguesia, promovendo
uma distribuição equilibrada dos visitantes e incentivando a visita de pontos de interesse
sustentáveis. Esta dissertação foca-se no desenvolvimento de uma aplicação móvel protótipo
destinada a turistas, através do qual recebem recomendações de visitas sustentáveis.
Para validar os requisitos funcionais do protĂłtipo, mais especificamente o processo de
criação de visitas, foram desenvolvidos testes unitários, testes de integração, e testes manuais.
Para avaliar a usabilidade do protĂłtipo, foi adotada uma abordagem centrada no utilizador
durante a fase de conceção, em que foram utilizadas duas técnicas de usabilidade em parceria
com o ISTAR (centro de investigação do ISCTE) e com a Junta de Freguesia de Santa Maria
Maior, cujos resultados guiaram e validaram as decisões tomadas.
O protótipo desenvolvido contém mecanismos para medir a aderência dos turistas às recomendações
sugeridas através do algoritmo Dynamic Time Warping, proporcionando novas
oportunidades de pesquisa nesta área
Design & Deploy Web 2.0 enable services over Next Generation Network Platform
The Next Generation Networks (NGN) aims to integrate for IP-based telecom
infrastructures and provide most advance & high speed emerging value added
services. NGN capable to provide higher innovative services, these services
will able to integrate communication and Web service into a single platform. IP
Multimedia Subsystem, a NGN leading technology, enables a variety of
NGN-compliant communications services to interoperate while being accessed
through different kinds of access networks, preferably broadband. IMS-NGN
services essential by both consumer and corporate users are by now used to
access services, even communications services through the web and web-based
communities and social networks, It is key for success of IMS-based services to
be provided with efficient web access, so users can benefit from those new
services by using web-based applications and user interfaces, not only NGN-IMS
User Equipments and SIP protocol. Many Service are under planning which
provided only under convergence of IMS & Web 2.0. Convergence between Web 2.0
and NGN-IMS creates and serves new invented innovative, entertainment and
information appealing as well as user centric services and applications. These
services merge features from WWW and Communication worlds. On the one hand,
interactivity, ubiquity, social orientation, user participation and content
generation, etc. are relevant characteristics coming from Web 2.0 services.
Parallel IMS enables services including multimedia telephony, media sharing
(video-audio), instant messaging with presence and context, online directory,
etc. all of them applicable to mobile, fixed or convergent telecom networks.
With this paper, this paper brings out the benefits of adopting web 2.0
technologies for telecom services. As the services are today mainly driven by
the user's needs, and proposed the concept of unique customizable service
interface
Personalization platform for multimodal ubiquitous computing applications
Dissertação para obtenção do Grau de Mestre em
Engenharia InformáticaWe currently live surrounded by a myriad of computing devices running multiple applications.
In general, the user experience on each of those scenarios is not adapted to each
user’s specific needs, without personalization and integration across scenarios. Moreover, developers usually do not have the right tools to handle that in a standard and generic way. As such, a personalization platform may provide those tools.
This kind of platform should be readily available to be used by any developer. Therefore, it must be developed to be available over the Internet. With the advances in IT infrastructure, it is now possible to develop reliable and scalable services running on abstract and virtualized platforms. Those are some of the advantages of cloud computing, which offers a model of utility computing where customers are able to dynamically allocate the resources they need and are charged accordingly.
This work focuses on the creation of a cloud-based personalization platform built on
a previously developed generic user modeling framework. It provides user profiling and
context-awareness tools to third-party developers.
A public display-based application was also developed. It provides useful information
to students, teachers and others in a university campus as they are detected by Bluetooth scanning. It uses the personalization platform as the basis to select the most relevant information in each situation, while a mobile application was developed to be used as an input mechanism. A user study was conducted to assess the usefulness of the application and to validate some design choices. The results were mostly positive
Personalizing the web: A tool for empowering end-users to customize the web through browser-side modification
167 p.Web applications delegate to the browser the final rendering of their pages. Thispermits browser-based transcoding (a.k.a. Web Augmentation) that can be ultimately singularized for eachbrowser installation. This creates an opportunity for Web consumers to customize their Web experiences.This vision requires provisioning adequate tooling that makes Web Augmentation affordable to laymen.We consider this a special class of End-User Development, integrating Web Augmentation paradigms.The dominant paradigm in End-User Development is scripting languages through visual languages.This thesis advocates for a Google Chrome browser extension for Web Augmentation. This is carried outthrough WebMakeup, a visual DSL programming tool for end-users to customize their own websites.WebMakeup removes, moves and adds web nodes from different web pages in order to avoid tabswitching, scrolling, the number of clicks and cutting and pasting. Moreover, Web Augmentationextensions has difficulties in finding web elements after a website updating. As a consequence, browserextensions give up working and users might stop using these extensions. This is why two differentlocators have been implemented with the aim of improving web locator robustness
Procyon LLC: From Music Recommendations to Preference Mapping
Procyon LLC had re-launched and renamed their music discovery site, Electra, to Capella, in 2008. Its core strength had originated from Electra’s proprietary technology, which used music libraries from real people, its members, to generating “automated word-of-mouth” recommendations, targeted advertising and editorial content. With the re-launch, Capella’s focus changed from a business-to-consumer destination site to a demonstration site for Procyon as it pursued a new business-to-business strategy. What led Procyon to make this strategic change? What products and services should it market, and to whom? This case describes the transition from music recommendation to preference mapping, and provides students with a variety of alternative partnering options to consider as they move forward
