Content Management

Significant value is often lost in the transition from procurement to contract management. Decisions made, or overlooked, during sourcing directly determine how effectively a contract can be managed. Poorly defined requirements, weak performance measures, and inadequate risk planning create constraints that cannot easily be fixed during delivery, leading to reduced outcomes and diminished value for money.

Critically, this lifecycle must also operate in reverse: insights and lessons learned from contract management must be systematically captured and fed back into future procurement activities. Without this feedback loop, organisations risk repeating the same design flaws and perpetuating value loss. Treating procurement and contract management as an integrated, continuous lifecycle is essential to preventing erosion of value and driving improved outcomes over time.

This document was written in the context of the curricular internship in the master’s degree in New Media and Web Practises of the School of Social and Human Sciences, New University of Lisbon. The internship took place at “SpikUP – Consultoria de Comunicação”, a computer company located in Corroios, municipality of Seixal, which is focused on creating solutions for micro and small-sized companies, through a list of services based on institutional websites and/or online shops, Social Media management, creation of Marketing Plans (digital or not), image editing and logo creation. It was decided to complete the master’s degree through this internship, not only because it created the chance to apply what I’ve learned in two of its most important subjects (Web Practises 1 and 2), but also to start a career in companies which have a portfolio of services based on digital solutions and platforms. This report includes a detailed description of all the tasks contained in the internship, alo...

In this paper we propose a lightly-supervised framework to rapidly build text classifiers for contextual advertising. Traditionally text classification techniques require labeled training documents for each predefined class. In the scenario of contextual advertising, advertisers often want to target to a specific class of webpages most relevant to their product or service, which may not be covered by a pre-trained classifier. Moreover, the advertisers are interested in whether a webpage is “relevant” or “irrelevant”. It is time-consuming to solicit the advertisers for reliable training signals for the negative class. Therefore, it is more suitable to model the problem as a one-class classification problem, in contrast to traditional classification problems where disjoint classes are defined a priori. We first apply two state-of-the-art lightly-supervised classification models, generalized expectation (GE) criteria (Druck et al., 2008) and multinomial naive Bayes (MNB) with priors (S...

In the last decade, the web has known a major evolution with the appearance of web 2.0 and its applications. One of those popular tools is the Online Video Social Networks (OVSN). Video content is becoming a predominant part of the daily life of users on the Web. Henceforth the study and modeling this kind of platforms, emerge as necessity. In this paper, we study the interaction of user community with videos shared and viewed in online video social networks. The concept of freedom giving to users in these platforms allows them to express their opinion toward those videos. Based on the analysis of the mechanisms of interaction in OVSN, we developed a personal opinion model for online users in this case. To deal with this problem we constructed a Petri Net model and we use it to derive a payoff function, these bring us to the Game theory field. Although our model is inspired from earlier studies, at the heart of our whole approach is abstracting the complex mechanism of interactions by the solution concept of Nash equilibrium, which allowed us to deal with richer problem instances. We conclude this paper by outlining several interesting lines of future work.

The newer generation of web browsers supports the client-side database, making it possible to run the full web application stacks entirely in the web clients. Still, the server side database is indispensable as the central hub for exchanging persistent data between the web clients. Assuming this characterization, we propose a novel web application framework in which the server archives its database states at predefined periods then makes them available on the web. The clients then use these archives to synchronize their local databases. Although the main purpose is to reduce the database scalability bottleneck, this approach also promotes self-archiving and can be used for time traveling. We discuss the consistency properties provided by this framework, as well as the tradeoffs imposed.

Architecting and designing high volume Web sites has changed immensely over the last six years. These changes include the availability of inexpensive Pentium based servers, Linux, Java applications, commodity switches, connection management and caching engines, bandwidth price reductions, content distribution services, and many others. This paper describes the evolution of the best practices within IBM in architecting sites that handle millions of page views per day. Discussed is the transition to multi-tiered architectures, the use of publish/subscribe software to reduce Web site hits, the migration from static to dynamic content, and techniques for caching of dynamic and personalized content.

Many features have been added to mobile devices to assist the user's information consumption. However, there are limitations due to information overload on the devices, hardware usability and capacity. As a result, content filtering in a mobile recommendation system plays a vital role in the solution to this problem. A system that utilises content filtering can recommend content which matches a user's needs based on user preferences with a higher accuracy rate. However, mobile content recommendation systems have problems and limitations related to cold start and sparsity. The problems can be viewed as first time connection and first content rating for non-interactive recommendation systems where information is insufficient to predict mobile content which will match with a user's needs. In addition, how to find relevant items for the content recommendation system which are related to a user's profile is also a concern. An integrated model that combines the user group identification and mobile content filtering for mobile content recommendation was proposed in this study in order to address the current limitations of the mobile content recommendation system. The model enhances the system by finding the relevant content items that match with a user's needs based on the user's profile. A prototype of the client-side user profile modelling is also developed to demonstrate the concept.

This papers provides an overview of e-learning from its fundamentals (what is knowledge, what is teaching) through how e-learning is being implemented using campus-wide Learning Content Management Systems (LCMS). While others, such as , detail the transformation of education in light of changing technologies, this paper attempts from a variety of perspectives to make sense of the transformation. E-learning can be difficult to understand because different authors use the term differently. Still, beyond these apparent differences lies agreement on basics that this paper explores. E-learning can best be understood in the broader context of using technology to meet society's needs for learning. It also requires us to understand that adult learners have psychological needs that e-learning must address. The Informing Science framework helps us understand that teaching in higher education involves a cast of roles that might best be performed by different specialists. One of the most important aspects of e-learning are Learning Objects and the various software tools that aid in their development, storage, use in teaching, and administration. This is because elearning is often delivered using specialized software that assists teachers to create their courses, the student to use coursework, and the administrator to make previously developed coursework available for re-use. Learning Objects are the raw material of such systems. E-learning can be delivered by a sole teacher or as part of a campus-wide effort. Campus-wide LCMSs make it possible for technologists, content specialists, instructional specialists, and students to work seamlessly to create and refine e-learning.

This paper describes ARCOLite, our low cost XML based client-server architecture for building and presenting digital heritage content in virtual museums. Our system includes components for creation and refinement of virtual artefacts including virtual reconstruction of buildings; XML content management, XML technologies for content repositories and presentation; and content visualisation using Web3D, virtual and augmented reality.

A complete tool chain starting with stereo photogrammetry based digitization of artifacts, their refinement, collection and management with other multimedia data, and visualization using virtual and augmented reality is presented. Our system provides a one-stop-solution for museums to create, manage and present both content and context for virtual exhibitions. Interoperability and standards are also key features of our system allowing both small and large museums to select components and build a bespoke system suited to their needs. For example, museums can build a tool set focused on the whole solution or just the visualization.

The number of digital content used in mobile devices such as smartphones or tablet PCs has been rapidly increasing along with the development of IT industry. At the same time, studies on digital content management are actively conducted. One of the previous studies defined CTI (Content Tracking Information) for efficient management of the information on digital content usage between mobile devices in an area in which the internet is inaccessible, and suggested

Framework? To answer this question 18 interviews were conducted. The interviews have been held with organizations that do use BiSL and with organizations that do not use BiSL. Among the interviews were three interviews with experts in the field of BiSL. The conclusion of our research is that organizational readiness is the deciding factor to use BiSL. To apply BiSL successfully there is a need of support, knowledge and a certain level of organizational maturity in business information management.

Business Information Services Library (BiSL) is a framework from Dutch origin that helps organizations shape Business Information Management. BiSL is not used by every organization in the Netherlands. The question is what moves organizations to start using BiSL or what motives do they have to reject the use of BiSL. The research question in this study is: What motivates the adoption (or non-adoption) of the BiSL Framework? To answer this question 18 interviews were conducted. The interviews have been held with organizations that do use BiSL and with organizations that do not use BiSL. Among the interviews were three interviews with experts in the field of BiSL. The conclusion of our research is that organizational readiness is the deciding factor to

In this article, we present the control framework and services scenarios of provisioning N-Screen services in interactive digital signage. Digital Signage provides a variety of high-resolution content and information displays at different public places and events. Provisioning N-Screen services in interactive digital signage enables the service providers to provide content to heterogeneous devices, allows the end user to share content from the digital signage to the user N-Screen devices and vice versa at different locations and times. We provide N-Screen services in interactive digital signage by adapting the content user interface according to user's N-Screen device size, layout, localized content adaptation, synchronization and session continuity over heterogeneous devices. We introduce the N-Screen User Interface Management Server (NUIMS), Digital Signage Management Server (DSMS), and Localized Content and Session Management Agent (LCSMA) to support N-Screen services. Furthermore, the N-Screen Devices Repository (NDR) at the DSMS keeps the users N-Screen devices static profile in order to share the content across all of their devices, and the LCSMA maintains the dynamic profile to synchronize content on heterogeneous devices. In addition, we suggest procedures, protocols and service scenarios to share the content of the digital signage to user's N-Screen devices, methods to synchronize the content display over heterogeneous signage displays with content session continuity and to share with other users using the user information server.

This paper presents a knowledge management experiment realized in an industrial company. Our research concerns the development of a project memory to capitalize Information and Knowledge created, shared and reused in a product design project. The project memory is based upon a domain ontology called OntoDesign which enables to easily exploit it. This is implemented with the Semantic Web technologies in order to provide a framework for the annotation and the reuse of knowledge. This article describes the design rationale of OntoDesign.

The aerospace and defence sectors are subject to mandatory compliance involving XML standards, especially in the content and management of classified documents. Such companies are well represented in the West Focus region and this is an area where Government and industry have identified burgeoning computing skills shortages, partly because the lower, less skilled end of the software and associated ICT sector is increasingly outsourced to India and other countries. Thus West Focus/Kingston University set a survey & study in motion aimed at identifying skills gaps in this sector which will enable us to propose a strategy as to how any skills gaps discovered could be addressed.

A content-based image retrieval system where an active learning strategy is used to gain relevance feedback (RF) is described. In this way retrieving process may be highly accelerated without significant degradation of accuracy Searching procedure was performed through the two basic steps: an objective one, based on the Euclidean distances and a subjective one based on the user's relevance feedback. Images recognized from user as the best matched to a query are labeled and used for updating the query feature vector through a RBF (radial basis function) neural network. In this process user change feature vector which became more refined and appropriate for future search. In practice, several iterative steps are sufficient, as confirmed by intensive simulations.

Digital libraries are being recognized as important tools for the conservation of indigenous and traditional knowledge that help to connect cultural heritage to technology. This paper analyses the role of two India based-mainstream initiatives-Traditional Knowledge Digital Library and Tribal Digital Document Repository in protecting knowledge in the digital era. The cross-checks of data were obtained from the official websites of TKDL and Tribal Repository along with policy papers, technical reports and scientific literature. Using document analysis and platform observation, the research examines preservation tactics, metadata norms, software functionalities and mechanisms, access functions, and usage. One such initiative is TKDL, which has created a digital database of more than 34 million pages from about 454,000-515,000 thousand Indian systems of medicine formulations adopting multilingual digitization and the Traditional Knowledge Resource Classification system into IT by CSIR in 2001 to document Ayurveda, Unani, Siddha, Yoga and Sowa Rigpa systematically.TDR launched by Ministry of Tribal Affairs consisting 10,000 plus digital resources maintain documentation and archival record of the tangible and intangible heritage and culture of Indian tribes to enable ethnographic, sociological, linguistic,cultural studies for achieving individuality in cultural contents. The study shows how these digital libraries contribute not only to preserving indigenous knowledge, but also to increasing accessiblity, use of research, and intergenerational transfer. TKDL and TDR are leading the best practices in information curation, metadata management and user centric design. This paper has highlighted the importance of digital libraries for harmonizing traditional knowledge with technological advancement, safeguarding cultural continuation and preventing its exploitation in the global knowledge resource.

The explosion of user-generated content on the Social Web published from mobile devices has seen reporting applications grow in popularity from self-reporting style workout tracking applications like Fitocracy1 to community reporting applications like FixMyStreet2. In this paper, we introduce the concept of social mobile reporting where a community of people report on issues within their environment. We discuss annotating contextual metadata to reports, and the use of gamification to create an engaging user experience. We propose a design of the architecture of a social reporting framework including a description of the reports server that incorporates semantic data harvesting and provision. We outline a mobile application including game design elements of the mobile user experience, and a discussion of imaging technology to aid in processing of citizen reports and we provide some ideas for future work along with our conclusions.

Se entiende por diseño de la interfaz​, a la definición de forma y funcionalidad que va a tener un sistema; teniendo en cuenta criterios como usabilidad, lineamientos de marca, el hardware que va a sostener el planteamiento de una interfaz, entre otros.
A diario la industria y el mercado requieren de profesionales que puedan afrontar de forma eficaz el planteamiento del diseño de interfaces para productos digitales. En las aulas los estudiantes suelen tener problemas para tangibilizar conceptos propios del diseño de interfaces; por esto surge la necesidad de salir con caminos creativos para traer estos conceptos a las aulas y prepararlos para poder asumir los retos que el mercado va a demandar. Una de las estrategias que planteo es una metodología ​para elaborar propuestas de diseño a través del análisis y compresión de estructuras de cualquier site utilizando diversos componentes de la anatomía de un sitio web y aplicando diversos criterios de usabilidad que existen en la generación de piezas digitales. Mediante este acercamiento, fácil de ser aplicado en la enseñanza del diseño de interfaces, es posible que el futuro diseñador comprenda su lugar dentro del flujo de trabajo y la totalidad de sus aportes en la gestión de proyectos de diseño en torno a sistemas digitales.

La simbiosis entre los profesionales Front-End y los Diseñadores de Interfaz se hace tangible por medio de materiales y momentos tan personales, como el trabajo en el aula y el empleo de materiales de diseño que permitan regresar a la comprensión básica de estructuras y jerarquías que, para ambos mundos (el visual y el de programación) nos hermanan en la tarea de desarrollo de productos; generando un espacio multidisciplinario, valorado hoy en los diferentes campos de acción de los diseñadores. Para finalizar, la participación en este Taller permitirá presentar una aproximación a las técnicas y materiales requeridos para esta nueva mirada sobre la enseñanza para el Diseño de Interfaces de Usuario.

Federated identity platform on the basis of digital content require sophisticated descriptions of that content, as well as service-oriented carrier architectures that allow negotiating and enforcing contract and license schemes in heterogeneous digital application environments. So this paper gives ontology in the Web Ontology Language (OWL) for federated identity systems, giving explicit, formal, and general specifications of a conceptualization of such architecture. OWL ontologies are standardized, machine-readable formats that support automated processing with Semantic Web applications. Intermediate concepts, concepts between base-level concepts and higher level concepts, are central in a federated identity system.

The notion of Linkbacks between websites has been developed to enable authors to keep track of who is linking to their pages. Authors receive notifications when other authors link to their pages, which is especially useful in the blogging community. One of the most well-known of several protocols which has been developed for Linkbacks is Trackback which has been developed within the blogging system, MoveableType.

Echoing the recent revival of elite studies, we ask how financialization shapes the composition of contemporary elites and how organizational mechanisms transform its characteristics in terms of class, gender and race. We ask whether the bureaucratization of finance contributed to a 'purge' of particularisms. Or to the contrary, whether class, race and gender have become more salient criteria of elite selection with the emergence of neo-patrimonial organizational forms? Using Orbis data on legal forms of financial firms, and original sociodemographic data on founders and managers in key firms, we show that neo-patrimonial organizational forms based on trust networks are spreading within finance. Moreover, we demonstrate the impact of organizational forms on elite reproduction along gender, race and class lines. White men with upper-class background are over-represented in neo-patrimonial firms-mostly found in the hedge fund and private equity industry-compared to bureaucratic firms mostly found in banking. We suggest that financialization is not a modernization process but a recombination of bureaucracy and neopatrimonial logics.

Web-based data sources, particularly in Life Sciences, grow in diversity and volume. Most of the data collections are equipped with common document search, hyperlink and retrieval utilities. However, users' wishes often exceed simple document-oriented inquiries. With respect to complex scientific issues it becomes imperative to aid knowledge gain from huge interdependent and thus hard to comprehend data collections more efficiently. Especially data categories that constitute relationships between two each or more items require potent set-oriented content management, visualization and navigation utilities. Moreover, strategies are needed to discover correlations within
