This paper focuses in making an emotional and affective analysis of the game Desafio Sebrae, a business game that simulates the management of a virtual company. A survey was conducted in order to discover the emotions and instincts that are most present in...
 
Discarding Similar Data with Autonomic Data Killing Framework Based on High-Level Petri Net Rules: An RSS Implementation
Found in: Autonomic and Autonomous Systems, International Conference on
By Wallace Pinheiro, Marcelino Campos Oliveira Silva, Thiago Rodrigues, Geraldo Xexéo, Jano Souza
Issue Date:March 2010
pp. 110-115
This paper describes the evolutions obtained in the autonomic Data Killing framework that was proposed to eliminate undesirable data. The focus now is about discarding similar data. In order to do it, a modeling method is proposed that uses active rules to...
 
Differential Tag Clouds: Highlighting Particular Features in Documents
Found in: Web Intelligence and Intelligent Agent Technology, IEEE/WIC/ACM International Conference on
By Geraldo Xexéo, Fernando Morgado, Patrícia Fiuza
Issue Date:September 2009
pp. 129-132
This paper introduces the concepts of “summary tag cloud” and “differential tag cloud”. A summary tag cloud is a unique tag cloud that summarizes the contents of all the documents in a set. A differential tag cloud is a tag cloud that highlights the partic...
 
Autonomic collaborative RSS: An implementation of autonomic data using data killing patterns
Found in: International Conference on Computer Supported Cooperative Work in Design
By Wallace A. Pinheiro, Marcelino C. O. Silva, Ricardo Barros, Geraldo Xexeo, Jano de Souza
Issue Date:April 2009
pp. 492-497
Corporate and personal computers are flooded by a huge amount of data. Among them, there are irrelevant, similar, false, wrong and obsolete data. Besides, the treatment of this data is relatively complex. Systems need to check, transform, adapt, and summar...
 
Does conference participation lead to increased collaboration? A quantitative investigation
Found in: International Conference on Computer Supported Cooperative Work in Design
By Bruno A. Osiek, Geraldo Xexeo, Adriana S. Vivacqua, Jano M. de Souza
Issue Date:April 2009
pp. 642-647
Conferences are an important environment for academic knowledge exchange, and are valued by researchers as a good way to increase ones social network and meet potential collaborators. The question we investigate in this work is whether conferences actually...
 
Autonomic RSS: Discarding Irrelevant News
Found in: Autonomic and Autonomous Systems, International Conference on
By Wallace A. Pinheiro, Thiago de S. Rodrigues, Marcelo A. R. da Silva, Márcio A. N. da Silva, Marcelino Campos Oliveira Silva, Geraldo Xexéo, Jano M. de Souza
Issue Date:April 2009
pp. 148-153
Information overload is becoming a big problem in the modern world. Several technologies face this problem, amongst them feed aggregators. Using this technology, users receive a huge amount of news that may contain a large number of irrelevant bits of info...
 
Using Wavelets to Classify Documents
Found in: Web Intelligence and Intelligent Agent Technology, IEEE/WIC/ACM International Conference on
By Geraldo Xexéo, Jano de Souza, Patrícia F. Castro, Wallace A. Pinheiro
Issue Date:December 2008
pp. 272-278
Currently, Fourier and cosine discrete transformations are used to classify documents. This article proposes a new strategy that uses wavelets in the representation and reduction of data text. Wavelets have been extensively used for dimensionality reductio...
 
TIGRAS: A Topology-Independent Gradient Search Approach for Peer-to-Peer Key Look Up
Found in: Computational Science and Engineering, IEEE International Conference on
By Mutaleci Miranda, Geraldo Xexeo, Jano Moreira de Souza
Issue Date:July 2008
pp. 197-202
In this work, we present a Topology-Independent Gradient Search method for key look up in P2p networks. The approach is inspired in the way ants perceive chemical gradients in their environment to search for food. In our method, a gradient of estimated dis...
 
Autonomic Patterns: Modelling Data Killing Patterns Using High-Level Petri Nets
Found in: Autonomic and Autonomous Systems, International Conference on
By Wallace A. Pinheiro, Geraldo Xexéo, Jano M. de Souza
Issue Date:March 2008
pp. 198-203
Pattern development for complex systems is a common practice nowadays. These patterns delineate the development of many systems, identifying behaviours and structures that can be re-used in several problems. Autonomic Data Killing Patterns represent a need...
 
Semi-Supervised Clustering of XML Documents: Getting the Most from Structural Information
Found in: Data Engineering Workshops, 22nd International Conference on
By Eduardo Bezerra, Marta Mattoso, Geraldo Xexeo
Issue Date:April 2006
pp. 88
As document providers can express more contextualized and complex information, semi-structured documents are becoming a major source of information in many areas, e.g., in digital libraries, e-commerce or Web applications. A particular characteristic of su...
