Extracting and Utilizing Social Networks from Log Files of Shared Workspaces

Log files of online shared workspaces contain rich information that can be further analyzed. In this paper, log-file information is used to extract object-centric and user-centric social networks. The object-centric social networks are used as a means for assigning concept-based expertise elements to users based on the documents that they created, revised or read. The user-centric social networks are derived from users working on common documents. Weights, called the Cooperation Index, are assigned to links between users in a user-centric social network, which indicates how closely two people have collaborated together, based on their history. We also present a set of tools that was developed to realize our approach.peer-reviewe

PROFICIENT: Productivity Tool for Semantic Interoperability in an Open IoT Ecosystem

The Internet of Things (IoT) is promising to open up opportunities for businesses to offer new services to uncover untapped needs. However, before taking advantage of such opportunities, there are still challenges ahead, one of which is the development of strategies to abstract from the heterogeneity of APIs that shape today's IoT. It is becoming increasingly complex for developers and smart connected objects to efficiently discover, parse, aggregate and process data from disparate information systems, as different protocols, data models, and serializations for APIs exist on the market. Standards play an indisputable role in reducing such a complexity, but will not solve all problems related to interoperability. For example, it will remain a permanent need to help and guide data/service providers to efficiently describe the data/services they would like to expose to the IoT. This paper presents PROFICIENT, a productivity tool that fulfills this need, which is showcased and evaluated considering recent open messaging standards and a smart parking scenario

Data Privacy Vocabularies and Controls: Semantic Web for Transparency and Privacy

Managing Privacy and understanding the handling of personal data has turned into a fundamental right-at least for Europeans-since May 25th with the coming into force of the General Data Protection Regulation. Yet, whereas many different tools by different vendors promise companies to guarantee their compliance to GDPR in terms of consent management and keeping track of the personal data they handle in their processes, interoperability between such tools as well uniform user facing interfaces will be needed to enable true transparency, user-configurable and -manageable privacy policies and data portability (as also implicitly promised by GDPR). We argue that such interoperability can be enabled by agreed upon vocabularies and Linked Data

State-of-the-art assessment on the implementations of international core data models for public administrations

Public administrations are often still organised in vertical, closed silos. The lack of common data standards (common data models and reference data) for exchanging information between administrations in a cross-domain and/or cross-border setting stands in the way of digital public services and automated flow of information between public administrations. Core data models address this issue, but are often created within the closed environment of a country or region and within one policy domain. A lack of insight exists in understanding and managing the life-cycle of these initiatives on public administration information systems for data modelling and data exchange. In this paper, we outline state-of-the-art implementations and vocabularies linked to the core data models. In particular we inventoried and selected existing core data models and identified tendencies in current practices based on the criteria creation, use, maintenance and coordination. Based on the analysis, this survey suggest research directions for policy and information management studies pointing to best practices regarding core data model implementations and their role in linking isolated data silos within a cross-country context. Finally we highlight the differences in their coordination and maintenance, depending on the state of creation and use

Towards a new generation of Governmental Portals

A apresentação foi realizada no âmbito da 4ª Semana do Inovação em Gestão Pública que aconteceu em Brasília, de 26 a 29 de novembro de 2018, com o tema “Serviço Público para o Futuro”. O evento foi fruto de uma parceria entre o Ministério do Planejamento, Desenvolvimento e Gestão (MP), a Escola Nacional de Administração Pública (Enap), o Tribunal de Contas da União (TCU), a Faculdade Latino-Americana de Ciências Sociais (Flacso), e a Agência Nacional de Telecomunicações (ANATEL). Teve como objetivo reunir pensadores e líderes da área de inovação para compartilhar conhecimentos e experiências com o intuito de inspirar a audiência presente, promover o aprendizado e provocar o debate sobre o tema no âmbito do setor público brasileiro. Nesse contexto, a 4ª Semana de Inovação buscou discutir as possibilidades e desafios da inovação pública para a transformação de serviços públicos, fomentando o foco no cidadão e o desenvolvimento de um governo mais ágil e receptivo às demandas da sociedade. Os tópicos abordados durante a Semana incluem inovações e suas aplicações em políticas públicas, novas tendências em tecnologia e seus usos para gerar valor público, transformação digital no governo e promoção da sustentabilidade, inclusão, aprendizagem e diversidade através da inovação.10 p.Inovaçã

Annotation-Based Access Control for e-Professionals

Collaborative Working Environments (CWE) provide shared workspaces that enable eProfessionals to work together and share resources that they own. Most current shared workspaces provide coarse-grained role-based access control policies which bring the functionalities of shared workspaces under question. In this paper, we present Annotation- Based Access Control, an approach towards access control which benefits from user annotations to annotate eProfessionals using various fixed and desired open vocabularies (tags) and helps to build a more flexible access control mechanism based on relationships among eProfessionals (or people). We also present our prototype, a gadget, which we have developed to enable this access control mechanism and evaluate it
