L'objectif de cette thèse est d'instrumentaliser des moyens, centrés utilisateur, de représentation, d'acquisition, d'enrichissement et d'exploitation des métadonnées décrivant des documents multimédias socio-personnels. Afin d'atteindre cet objectif, nous avons proposé un modèle d'annotation, appelé SeMAT avec une nouvelle vision du contexte de prise de vue. Nous avons proposé d'utiliser des ressources sémantiques externes telles que GeoNames , et Wikipédia pour enrichir automatiquement les annotations partant des éléments de contexte capturés. Afin d'accentuer l'aspect sémantique des annotations, nous avons modélisé la notion de profil social avec des outils du web sémantique en focalisant plus particulièrement sur la notion de liens sociaux et un mécanisme de raisonnement permettant d'inférer de nouveaux liens sociaux non explicités. Le modèle proposé, appelé SocialSphere, construit un moyen de personnalisation des annotations suivant la personne qui consulte les documents (le consultateur). Des exemples d'annotations personnalisées peuvent être des objets utilisateurs (e.g. maison, travail) ou des dimensions sociales (e.g. ma mère, le cousin de mon mari). Dans ce cadre, nous avons proposé un algorithme, appelé SQO, permettant de suggérer au consultateur des dimensions sociales selon son profil pour décrire les acteurs d'un document multimédia. Dans la perspective de suggérer à l'utilisateur des évènements décrivant les documents multimédias, nous avons réutilisé son expérience et l'expérience de son réseau de connaissances en produisant des règles d'association. Dans une dernière partie, nous avons abordé le problème de correspondance (ou appariement) entre requête et graphe social. Nous avons proposé de ramener le problème de recherche de correspondance à un problème d'isomorphisme de sous-graphe partiel. Nous avons proposé un algorithme, appelé h-Pruning, permettant de faire une correspondance rapprochée entre les nœuds des deux graphes : motif (représentant la requête) et social. Pour la mise en œuvre, nous avons réalisé un prototype à deux composantes : web et mobile. La composante mobile a pour objectif de capturer les éléments de contexte lors de la création des documents multimédias socio-personnels. Quant à la composante web, elle est dédiée à l'assistance de l'utilisateur lors de son annotation ou consultation des documents multimédias socio-personnels. L'évaluation a été effectuée en se servant d'une collection de test construite à partir du service de médias sociaux Flickr. Les tests ont prouvé : (i) l'efficacité de notre approche de recherche dans le graphe social en termes de temps d'exécution ; (ii) l'efficacité de notre approche de suggestion des événements (en effet, nous avons prouvé notre hypothèse en démontrant l'existence d'une cooccurrence entre le contexte spatio-temporel et les événements) ; (iii) l'efficacité de notre approche de suggestion des dimensions sociales en termes de temps d'exécution.

This thesis is an investigation of campus/community radio in Canada and an exploration of its motivations and methods of using social media as a tool to interact with listeners. It develops and applies a methodology referred to as S.M.I.L.E.S., a methodology to create triangulation and validate results when researching in areas involving social media and minimal previous literature available. Radio station staff and volunteer programmers use social media, traditional digital and non-digital methods to gather feedback about the show and/or station, promote the show and/or station, provide additional content to the listener off-air, communicate about the station itself, and achieve personal, station, and community growth. Results suggest that campus/community radio members use social media very differently than commercial or public radio station. As a whole, the campus/community radio sector is generally slow in providing support and policy when facilitating technological change, which has resulted in tentative use and lack of support for social media. Geographical location is also irrelevant as regards the utilization of social media. Also, programmers must be careful in identity management when engaging in online communication, as well as using social media as a fundraising tool and forum for information dissemination. Finally, stations need to consider implementing policy surrounding social media in order to facilitate growth within the industry. / Generously funded in part by the Snowden Program, at the School of Environmental Design and Rural Development, University of Guelph.

Ce mémoire aborde les usages militants des médias sociaux dans un contexte particulier, celui de la Révolution Tunisienne (du 17 décembre 2010 au 14 janvier 2011). Le fait d'avoir vécu et observé l'engouement pour l'usage du Web durant les évènements nous a menée à nous questionner sur ce phénomène. Nous nous sommes intéressées à la façon dont le Web, plus précisément les médias sociaux, a été, concrètement, utilisé du 17 décembre 2010 au 14 janvier 2011. L'objectif de cette recherche vise, tout d'abord, à étudier l'utilisation des médias sociaux dans le contexte de la Révolution Tunisienne, pour comprendre la manière dont s'est exprimé le cyber militantisme sur ces interfaces. Nous nous sommes demandé si les cyberactivistes tunisiens étudiés ont pu constituer un contre-pouvoir pouvant mener à l'émergence d'un contre-public. Il s'est avéré, à l'issu de notre recherche, que les médias sociaux, en l'occurrence les blogues et le site de réseau social Facebook, ont été utilisés par les cyberactivistes de quatre manières différentes : d'abord à des fins d'expression, par exemple pour donner un point de vue ou pour réagir sur les évènements; ensuite pour diffuser de l'information, notamment pour contrer la censure; puis à des fins d'analyse de la situation économique, sociale ou encore politique; enfin et dans une moindre mesure, à des fins d'organisation d'activités de contestation, par exemple pour relayer les dates et lieux de celles-ci. Notre recherche a permis de mettre en évidence le rôle des cyberactivistes en tant que contre public durant ce mois révolutionnaire et suggère que leurs activités de militantisme dans l'espace Internet virtuel a permis de préparer la reconquête de l'espace public réel, détenu et durement réprimé par le régime « Ben Alien ». Cette recherche constitue un début et s'inscrit dans une multitude d'autres questionnements sur la Révolution Tunisienne. Il reste encore beaucoup à apprendre et à comprendre sur la Révolution Tunisienne de 2011. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Usages, cyberactivisme, Révolution tunisienne, espace public, militantisme.

The Library 2.0 model is one of many library service models. It has its origin in, and borrowed concepts from, Web 2.0 which is associated with Web applications that facilitate participatory information sharing, interoperability, user-centred design and collaboration on the Web. The focus of Library 2.0 is on user-centred change and participation in the creation of content. Different scholars and researchers have discussed Library 2.0 and numerous articles have been written discussing the implementation of the model in academic libraries. Findings are that academic library users, who are becoming more involved and familiar with Web 2.0 technologies, no longer want to use the library only as a reading space or a place to use books and journals without being able to make suggestions and have their views heard. The Library 2.0 model facilitates this and, as it encourages sharing and participation, is considered a suitable model for academic libraries. The purpose of this study was to investigate the implementation of Library 2.0 within the libraries of the University of KwaZulu-Natal (UKZN) and the difficulties encountered when using Library 2.0 technologies to deliver their services. To achieve the purpose of the study both primary and secondary sources of data were used, including literature from various sources (journals, books and information found on websites). Interviews and self-administered questionnaires were the instruments used to collect data. The population of the study consisted of all subject librarians on the UKZN campuses, the campus librarians, and the Library Director. Data were analysed through content analysis and the use of SPSS and presented in the form of figures. It was found that UKZN libraries were slow in terms of involving the technologies associated with Library 2.0 in their services. Only Facebook and a weblog are used by the UKZN libraries and it is evident that more needs to be done in terms of implementing and promoting the technologies that encourage collaboration and interaction with users – the essence of Library 2.0. It has been said by different scholars and researchers that institutions that are perceived to be slow in involving new technologies in their services, are at risk of becoming irrelevant to their users. These users will then move to other services who can better meet their needs. Therefore, it is crucial for UKZN libraries to embrace these technologies if they want to keep up and remain relevant to the ever changing needs of their users. / Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2012.

World Wide Web (WWW) has become the greatest repository of information that man has ever assembled and it is continuously growing. WWW transformed itself into a generative environment that fosters innovation through the advance of technologies and a shift in people's perception of the Weband how they use it. The new WWW or Future Internet is that of an Internet of Services and Internet of Things.Naturally, a series of questions arise from this context: how do you filter things to create more value than you currently get? how do you aggregate things in an intelligent and easy way instead of doing it in your head? The world cannot be described unambiguously, so how can you allow users to deal with the world in their own way, based on their understanding? Levine in his book "Cluetrain manifesto" was arguing that markets are conversations so how can users be involved in the conversation? how can users be empowered with easy consumption of the services, information, things that they found around?However design and deployment of such software capable of direct interaction and empowerment of the end-user is still an issue. We have on one side users that have ideas, but do not have technical background and lack programming skills to do the development by themselves. On the other side, we have large amounts of data, resources and services that could be aggregated both in terms of data, but most important in terms of behavior to innovate and create new things.Our goal in this thesis is to address this lack of tools that are capable of direct interaction andempowerment of end-users, in a unified manner. Thus our main contribution in this thesis is the development of a holistic approach for web based systems that are user-centric and that integrate data, services and behavior available on the Web 2.0.

Ermöglicht durch die Medientechnologien des Web 2.0 hat sich seit Mitte der 2000er Jahre ein kulturelles Nachahmungsphänomen im Internet entwickelt. YouTube, Flickr, Twitter und Co. haben zu einer Potenzierung und Beschleunigung der ohnehin vorhandenen ,Kultur des Kopierens’ geführt. Anhand der mehrteiligen Arbeit I’m too sad to tell you des Konzeptkünstlers Bas Jan Ader und deren Nachahmungen und Adaptionen wird hier beispielhaft untersucht, welche Auswirkungen, Potentiale und Begrenzungen sich aus dem Nachahmungsphänomen ableiten lassen und inwiefern der über die Videoplattformen erstellte User-Generated-Content als Archiv- und Quellenmaterial für eine künstlerische Forschung fungieren kann.

Organizations today are adopting business intelligence (BI) systems at a fast pace with the expectation that these systems will help them make better business decisions and improve their performance. But with the ever changing industry dynamics and variable business needs of end-users, the BI requirements of organizations are also getting unpredictable and increasingly harder to deliver by the service providers. Additionally, the advancement of web 2.0 & enterprise 2.0 technologies has opened up more possibilities for the development of user-centric innovative business applications. Enterprise BI Mashups are a specific breed of such technologies that have the potential to empower end-users with self-service capabilities and facilitate problem-solving in ad-hoc situational BI scenarios. This research project attempts to explore the current landscape of Business Intelligence (BI) Mashups and to identify gaps in technology with respect to user requirements and corporate objectives. Through an empirical investigation of BI mashups use cases, specific issues and challenges associated with the use of mashups in BI have been ascertained. Working in collaboration with IBM Cognos, we have formulated a taxonomy and utility framework for Enterprise BI Mashups. The formulated taxonomy provides a basic framework for understanding the domain of BI mashups and is aimed to aid application development initiatives for creating BI mashups toolkits. The utility framework draws upon real-world use cases for BI Mashups as well as pertinent software design patterns that can facilitate the development of BI mashup tools and services. These frameworks are expected to advance an understanding of business process requirements that can be satisfied through the use of Enterprise BI Mashups, and also aid in the development of mashup toolkits targeted at BI end-users.

Web2.0的盛行改變了目前網路資訊傳播方式，民眾對網路資訊擴散參與度也日益增加及重要，電子醫學網站肩負健康衛教資訊及新技術推廣的重責，如何利用Web2.0的特性，讓民眾可以輕易、適時、適所獲得相關醫學資訊是所有醫學網站所要研究的課題。因此除了如何提供質優量多且可信度、專業性高的醫療資訊外，醫學網站更要研究並了解民眾的實際需求期望及最易接受的資訊管道方式，使得相關資訊能無礙地傳送到民眾面前。本研究即以個案研究的方式，來探討如何藉由Web 2.0網路資訊平台及資訊管道設計概念，利用創新擴散策略思考及方法來推廣相關新醫療科技，使非營利組織也能像其他電子商務網站的經營方式一樣，與使用者建立價值共創的關係；並繼續延伸探討後續推廣策略建議，以提供相關網站經營參考。 本研究選定中華民國口腔雷射醫學會網站，作為本研究的個案網站，不同於一般醫學會網站的社群經營，都是以傳統單向的型錄式資訊提供方式為主，缺乏互動性及使用者導向設計。本研究的個案網站卻是集合所有專業會員醫師之群力，將民眾所需要的臨床案例、口腔新聞、醫療知識和新知、線上諮詢功能及院所指南等，加以整合，讓民眾可以藉由簡單的資訊搜尋引擎方式來找到相關完整資訊，創造出新的經營模式。本研究即藉由問卷及深度訪談，分析網路使用民眾對個案的知識創新推廣模式的接受度，並以此為基礎，研究歸納出可行的網站經營建議方案，作為個案網站在未來的經營方向之參考。 / The popularity of the concept of Web 2.0 has altered the ways information transmitted, and increases the importance of the participation of internet users on disseminating information. Electronic-health websites (e-health websites) have great responsibility of promoting the public health education and new medical technologies and treatments to the public. It is an important task for these websites applying the concept of web 2.0 to provide the public the easy and timely access to relevant information. In addition, e-health websites should also offer trustworthy and professional health information to meet the expectation of the users. In this study we use a case study to examine how to apply Technology Acceptance Model (TAM) and the concept of web 2.0 to understand the promotion of the new medical technologies and treatments. The results will help Non-Profit Organization (NPO) to transform to a highly efficient information exchanging platform and also to establish the relationship of value co-creation website. Our case website is the Taiwan Academy of Laser in Dentistry (TALD) that is different from other medical websites using traditional approach of providing static information (Web 1.0). This website is interactive and user-oriented by integrating the medical cases from dentists, latest medical news, most recent medical breakthrough, functions of searching the nearest dentists, introductions of dental clinics, and son on. This new model allows the regular users to find the relevant information in a timely manner. By survey and in-depth interviews, we are able to analyze the users’ behavior and provide recommendations for management to improve its performance.

It has not only made it easier than ever for people to connect with each other, but is also a great influence on this generation of youths. The method of marketing library services through Facebook without intrusions into peoples’ privacy is worth pondering. The purpose of this study is to analyze the contents of university library Facebook/Plurk page and to explore it from viewpoints of librarians as well as readers. The research used content analysis to analyze the user activities on Facebook and Plurk among both National Taiwan University and Providence University students. In addition, a questionnaire was designed to understand readers’ experiences and viewpoints on the use of Social Networking Services by libraries. The questionnaire was sent over the internet and 727 responses were received and processed. Furthermore, the study interviewed library staff to investigate viewpoints of librarians on the social networking use by libraries. Based on the summarized results of the data, suggestions were made for university libraries regarding how to use Social Network to promote library services. The results of this study shows that National Taiwan University and Providence University use different management strategies on social networking. National Taiwan University has a social networking team with established standard operating procedures, as such, most of NTT’s postings are university activities and announcements. For Providence University, social networking is managed by one person and as a result, the posts are more personal, active and dynamic.
