Participatory democracy advances in virtually all governments. South America presents a prominent context with mixed culture and social predisposition. In 2012, civil, academic and governmental parties started elaborating the “Common Vocabulary of Social Participation” (vcps from the Brazilian name Vocabulário Comum de Participação Social), as a public and online process. By May, 2013, first re...

SemaPlorer is an easy to use application that allows end users to interactively explore and visualize a very large, mixed-quality and semantically heterogeneous distributed semantic data set in realtime. Its purpose is to acquaint oneself about a city, touristic area, or other area of interest. By visualizing the data using a map, media, and different context views, we clearly go beyond simple ...

This chapter discusses the relation between Social Networks and Semantics – two areas that have recently gathered a lot of attention from both academia and industry. We show how synergies between these two areas can be used to solve concrete problems, and we describe three approaches that demonstrate the potential for interconnecting these technologies. The first approach focuses on the semanti...

Insider attack and espionage on computer-based information is a major problem for business organizations and governments. Knowledge Management Systems (KMSs) are not exempt from this threat. Prior research presented the Congenial Access Control Model (CAC), a relationship-based access control model, as a better access control method for KMS because it reduces the adverse effect of stringent sec...

Based on URIs, HTTP and RDF, the Linked Data project [3] aims to expose, share and connect related data from diverse sources on the Semantic Web. Linked Open Data (LOD) is a community effort to apply the Linked Data principles to data published under open licenses. With this effort, a large number of LOD datasets have been gathered in the LOD cloud, such as DBpedia, Freebase and FOAF profiles. ...

Web 2.0. It aims to make it possible for the people to take responsibility for what they publish on the web, including organizations, businesses and individual users. These objectives, among others, drive most of the technologies and protocols recently standardized by the governing bodies. One of the great advantages of Web infrastructure is decentralization of publication. The primary motivati...

In this paper we propose the integration of the FOAF ontology, used to model people and their personal contacts, with semantic ontologies related to student competencies. In particular, the use of ontologies and other semantic web technologies allows us to create relations between the evolution of student educational experiences and their social network. For this to happen, we integrate FOAF wi...

The advent of the Semantic Web enables distributed publishing mechanisms on the Web as well as a large scale distributed knowledge store for machine agents with various purpose. Currently, significant amount of semantic web data (over 47,000,000 triples from over 130,000 web sites1) is available directly in RDF documents using semantic web vocabularies like Friend Of A Friend (FOAF) 2 and RDF S...

The current knowledge processing models can be classified into two categories-Man’s Knowledge Processing Model and Machine’s Knowledge Processing Model-according to literature reviews of knowledge processing studies in knowledge management and Artificial Intelligence. Man’s Knowledge Processing Model is based on knowledge management theory, especially the Second Generation Knowledge Management ...
