This paper presents the T-SWEETS algorithm, a novel approach for inferring trust in social networks and its deployment in a social network knowledge- based management platform, titled Konnen (Knowledge Organization in a Native Network ENvironment). An objective of trust inference is to recommend trust relationships. The features of T-SWEETS come fr...

Knowledge discovery in social networks is not a trivial task. Often research in this context uses concepts of data mining, social network analysis, trust discovery and sentiment analysis. The connected network of people is generally represented by a directed graph (social graph), whose formulation includes representing people as nodes and their rel...

This paper presents a novel method to infer trustiness in social networks entitled T-SWEETS. It is also presents its application at Konnen, a knowledge management platform on social networks based. The features explored in T-SWEETS come from research done on related works from the literature and from an experiment development with a group of 34 peo...

The organizations aim to increase its competitiveness. In this context, they have been searching for new ways to improve their productivity, the quality of their products, and cost reduction. To achieve these goals, it is essential to use the collaborators’ potentials and the relationship among them to find and share tacit knowledge. Since tacit kn...

This paper presents the expert recommender system, called SWEETS, in its version 2.0, and its implementation in the environment A.M.I.G.O.S., a web based social network (WBSN). This environment is used as a communication and cooperation tool among employees from C.E.S.A.R. – a Brazilian innovative institute in software products. SWEETS uses folkson...

This case study describes the effects of using a Web Based Social Network (WBSN) approach to Knowledge Management in a Brazilian software development organization. During this work it was verified how the previous approach to Knowledge Management, a wiki based approach, did not work to this organization and how users voluntarily migrated from this...

A presente pesquisa propõe modificações para o a.m.i.g.o.s., uma rede social baseada na web (Web Based Social Network - WBSN). Esta WBSN é usada como ferramenta de comunicação e cooperação dos colaboradores do C.E.S.A.R. - um Instituto de Inovação de Produtos de Software do Recife. Estas modificações estão voltadas para melhorias no sistema automat...

This case study describes the effects of using a Web Based Social Network (WBSN) approach to Knowledge Management in a Brazilian software development organization. During this work it was proposed a Knowledge Management process, with some metrics related to its phases. These metrics have been monitored since January 2008 and have been analyzed in o...

Companies are looking for strategies to support members' communication and collaboration, which would help them to create, manage and share knowledge inside the organization. This work presents the a.m.i.g.o.s platform, which provides social networks features to support knowledge management. It shows how the use of social networks can help companie...

Companies are looking for strategies to support members' communication and collaboration, which would help them to create, manage and share knowledge inside the organization. This work presents how the use of social networks can help companies overcame this challenge by exchanging information through relationships between its members. It shows how...

Building self-adaptive applications is a complex and challenging task. Developers must consider several issues in addition to the implementation of the application-speci c functionalities. These issues include the selection of which environment elements must be monitored for detecting when adaptations should take place, how to perform the monitorin...

Building adaptive applications is a complex and challenging task. Developers must consider several issues in addition to the implementation of the application functional behavior. This work aims at reducing the complexity of building adaptive distributed applications by presenting a framework that provides a set of integrated tools for monitoring r...

Adaptation techniques allow software to modify its own functions and configuration in response to changes in its execution environment. In order to incorporate an adaptable behavior, an application must have a way to monitor the execution environment and discover relevant variations that requires reconfiguration.
