A survey of e-learning content aggregation standards

As e-learning gradually evolved many specialized and disparate systems appeared to fulfil the needs of teachers and students, such as repositories of learning objects, authoring tools, intelligent tutors and automatic evaluators. This heterogeneity raises interoperability issues giving the standardization of content an important role in e-learning. This article presents a survey on current e-learning content aggregation standards focusing on their internal organization and packaging. This study is part of an effort to choose the most suitable specifications and standards for an e-learning framework called Ensemble defined as a conceptual tool to organize a network of e-learning systems and services for domains with complex evaluation.

Distributed Energy Resources Management using Plug-in Hybrid Electric Vehicles as a Fuel-Shifting Demand Response Resource

In the smart grids context, distributed energy resources management plays an important role in the power systems’ operation. Battery electric vehicles and plug-in hybrid electric vehicles should be important resources in the future distribution networks operation. Therefore, it is important to develop adequate methodologies to schedule the electric vehicles’ charge and discharge processes, avoiding network congestions and providing ancillary services. This paper proposes the participation of plug-in hybrid electric vehicles in fuel shifting demand response programs. Two services are proposed, namely the fuel shifting and the fuel discharging. The fuel shifting program consists in replacing the electric energy by fossil fuels in plug-in hybrid electric vehicles daily trips, and the fuel discharge program consists in use of their internal combustion engine to generate electricity injecting into the network. These programs are included in an energy resources management algorithm which integrates the management of other resources. The paper presents a case study considering a 37-bus distribution network with 25 distributed generators, 1908 consumers, and 2430 plug-in vehicles. Two scenarios are tested, namely a scenario with high photovoltaic generation, and a scenario without photovoltaic generation. A sensitivity analyses is performed in order to evaluate when each energy resource is required.

Semantic data integration in a newspaper content management system

A newspaper content management system has to deal with a very heterogeneous information space as the experience in the Diari Segre newspaper has shown us. The greatest problem is to harmonise the different ways the involved users (journalist, archivists...) structure the newspaper information space, i.e. news, topics, headlines, etc. Our approach is based on ontology and differentiated universes of discourse (UoD). Users interact with the system and, from this interaction, integration rules are derived. These rules are based on Description Logic ontological relations for subsumption and equivalence. They relate the different UoD and produce a shared conceptualisation of the newspaper information domain.

Business Benefits of Content Management

Hyvällä sisällönhallinnalla on mahdollista vaikuttaa myönteisesti liiketoiminnalliseen tulokseen, jos sisällönhallinnan eri vaikutusmahdollisuudet tunnistetaan. Kun organisaatiossa syntyvä tieto on vapaasti saatavilla, ja sitä voidaan tulkita ja hyödyntää erilaisiin tarpeisiin, tietojärjestelmän avulla voidaan vauhdittaa kehitystä ja uuden tiedon löytämistä. Tiedon keskeisin tehtävä on kehittää ja parantaa organisaation osaamista, jolloin pitää olla tietoa siitä, mitä, miksi ja kuinka tietoa on käytetty organisaatiossa. Kaiken liiketoimintaprosesseissa tuotetun tiedon kohdalla pitäisi miettiä kolmea tiedonhallinnan osa-aluetta: tiedon luontia, hallintaa ja hyödyntämistä. Tavoitteena on saavuttaa yrityksen määrämuotoisen tietopääoman paras mahdollinen hallinta.Työssä kuvataan sitä, mitä sisällönhallinta on, sen eri tasoja, sen käsitteellistä sijoittumista tietämyksenhallintaan, sisällönhallinnan järjestelmiä ja niiden merkitystä liiketoimintaprosesseissa. Lisäksi tarkastellaan niitä syitä, joiden vuoksi yritykset kiinnostuvat organisaatiossa olevan määrämuotoisen tiedon sisällönhallinnasta. Lopuksi analysoidaan, millaisia voivat olla liiketoiminnalliset, kilpailulliset tai rahalliset tavoitteet, joita asetetaan sisällönhallinnan tietojärjestelmäprojektille. Työn tueksi on haastateltu neljän suomalaisen suuryrityksen sisällönhallinnan tietojärjestelmäprojektin asiantuntijoita. Heidän kommenttejaan on analysoitu ja niiden perusteella on tehty johtopäätöksiä niistä syistä, joiden vuoksi yritykset yleensä sijoittavat resurssejaan sisällönhallintaan.

Evaluating Web Content Management Systems Compatibility for Implementing Online Communities

The purpose of this study is to study whether a Web CMS can be used to implement and host an online community. The study is divided into two parts. The theoretical part contains the definition of Web CMS and clarifies the relation between an online community and a social software. The first part also defines the parameters, which must be taken account when choosing a Web CMS for hosting an online community. The practical part of the study contains analyses of three Web CMSs, Drupal, Liferay and Plone. All the three Web CMSs were analyzed using the technical and social parameters discovered in the theoretical part of the study. The primary objective is to investigate whether the selected Web CMS can be used to implement and host an online community. If hosting is possible, the secondary objective is to investigate whether the selected Web CMS have an effect to the online community.

Usability comparison of open source content management systems

The purpose of this thesis is to study, investigate and compare usability of open source cms. The thesis examines and compares usability aspect of some open source cms. The research is divided into two complementary parts –theoretical part and analytical part. The theoretical part mainly describes open source web content management systems, usability and the evaluation methods. The analytical part is to compare and analyze the results found from the empirical research. Heuristic evaluation method was used to measure usability problems in the interfaces. The study is fairly limited in scope; six tasks were designed and implemented in each interface for discovering defects in the interfaces. Usability problems were rated according to their level of severity. Time it took by each task, level of problem’s severity and type of heuristics violated will be recorded, analyzed and compared. The results of this study indicate that the comparing systems provide usable interfaces, and WordPress is recognized as the most usable system.

Evaluating digital marketing content management strategies in an international company.

The purpose of this thesis is to explore a different kind of digital content management model and to propose a process in order to manage properly the content on an organization’s website. This process also defines briefly the roles and responsibilities of the different actors implicated. In order to create this process, the thesis has been divided into two parts. First, the theoretical analysis helps to find the two main different content management models, content management adaptation and content management localization model. Each of these models, have been analyzed through a SWOT model in order to identify their particularities and which of them is the best option according to particular organizational objectives. In the empirical part, this thesis has measured the organizational website performance comparing two main data. On one hand, the international website is analyzed in order to identify the results of the content management standardization. On the other hand, content management adaptation, also called content management localization model, is analyzed by looking through the key measure of the Dutch page from the same organization. The resulted output is a process model for localization as well as recommendations on how to proceed when creating a digital content management strategy. However, more research is recommended to provide more comprehensive managerial solutions.

Modelling as learning: a consultancy methodology for enhancing learning in management teams

This article reviews the experiences of a practising business consultancy division. It discusses the reasons for the failure of the traditional, expert consultancy approach and states the requirements for a more suitable consultancy methodology. An approach called ‘Modelling as Learning’ is introduced, its three defining aspects being: client ownership of all analytical work performed, consultant acting as facilitator and sensitivity to soft issues within and surrounding a problem. The goal of such an approach is set as the acceleration of the client's learning about the business. The tools that are used within this methodological framework are discussed and some case studies of the methodology are presented. It is argued that a learning experience was necessary before arriving at the new methodology but that it is now a valuable and significant component of the division's work.

Ontology-based metadata for e-learning content

Nowadays, the popularity of the Web encourages the development of Hypermedia Systems dedicated to e-learning. Nevertheless, most of the available Web teaching systems apply the traditional paper-based learning resources presented as HTML pages making no use of the new capabilities provided by the Web. There is a challenge to develop educative systems that adapt the educative content to the style of learning, context and background of each student. Another research issue is the capacity to interoperate on the Web reusing learning objects. This work presents an approach to address these two issues by using the technologies of the Semantic Web. The approach presented here models the knowledge of the educative content and the learner’s profile with ontologies whose vocabularies are a refinement of those defined on standards situated on the Web as reference points to provide semantics. Ontologies enable the representation of metadata concerning simple learning objects and the rules that define the way that they can feasibly be assembled to configure more complex ones. These complex learning objects could be created dynamically according to the learners’ profile by intelligent agents that use the ontologies as the source of their beliefs. Interoperability issues were addressed by using an application profile of the IEEE LOM- Learning Object Metadata standard.

A gestão da informação sob a luz do Enterprise Content Management (ECM): um estudo de caso em uma universidade pública

This work involves the organization and content perspectives on Enterprise Content Management (ECM) framework. The case study at the Federal University of Rio Grande do Norte was based on ECM model to analyse the information management provided by the three main administrative systems: The Integrated Management of Academic Activities (SIGAA), Integrated System of Inheritance, and Contracts Administration (SIPAC) and the Integrated System for Administration and Human Resources (SIGRH). A case study protocol was designed to provide greater reliability to research process. Four propositions were examined in order to reach the specific objectives of identification and evaluation of ECM components from UFRN perspective. The preliminary phase provided the guidelines for the data collection. In total, 75 individuals were interviewed. Interviews with four managers directly involved on systems design were recorded (average duration of 90 minutes). The 70 remaining individuals were approached in random way in UFRN s units, including teachers, administrative-technical employees and students. The results showed the presence of many ECM elements in the management of UFRN administrative information. The technological component with higher presence was "management of web content / collaboration". But initiatives of other components (e.g. email and document management) were found and are in continuous improvement. The assessment made use of eQual 4.0 to examine the effectiveness of applications under three factors: usability, quality of information and offered service. In general, the quality offered by the systems was very good and walk side by side with the obtained benefits of ECM strategy adoption in the context of the whole institution
