This paper proposes a two-level feature selection to improves Naïve Bayes with kernel density estimation. The performance of the proposed feature selection is evaluated on question item set based on Bloom's cognitive levels. This two-level feature selection contains of filter and wrapper based feature selection. This paper uses chi square and information gain as the filter based feature selection and forward feature selection and backward feature elimination as the wrapper based feature selection. The result shows that the two-level feature selection improves the Naïve Bayes with kernel density estimation. The combination of chi square and backward feature elimination give more optimal quality than the other combination. © 2013 IEEE.

International Conference on Network and Service Management

Cardoso Eduardo Cerqueira Program Postgraduate in Electrical Engineering (PPGEE) Federal University of Pará (UFPA) Belém PA Brasil program Postgraduate in Science Computer (PPGCC) Federal University of Pará (UFPA) Belém PA Brasil Faculdade de Computção (FACOMP) Federal University of Pará (UFPA) Belém PA Brasil Institute of Informatics (INF) Federal University of Goiás (UFG) Goiânia GO Brasil

Software Defined Networking (SDN) has emerged as a new paradigm that highly increase the network management flexibility through simple but powerful abstractions. The key idea is decoupling the control plane, which makes the forward decisions, from the data plane, which effectively makes the forward. However, the OpenFlow, the main SDN enabler, is designed mainly by wired networks characteristics. As consequence, Wireless Mesh Networks (WMNs) is not suitable for operating as control plane and many wireless networks features are neglected in the OpenFlow, e.g.: power control and network ID. In addition, there are few effort research to extend SDN to wireless networks and these existing works focus on very specific issues of this integration. In this paper, we propose an architecture to extent the OpenFlow functionalities in order to proper deal with wireless networks, including an approach for transporting the control plane over wireless multihop networks. The extensions include new rules, actions, and commands, which bring the network management flexibility to the wireless context. We validated our proposal by implementing and testing some extensions in a small real world testbed. As a proof of concept, we illustrate the OpenFlow capability of isolation between research and production traffics in a wireless backhaul.

Human computation techniques have demonstrated their ability to accomplish portions of tasks that machine-based techniques find difficult. Query refinement is a task that may benefit from human involvement. We conduct an experiment that evaluates the contributions of two user types: student participants and crowdworkers hired from an online labor market. Human participants are assigned to use one of two query interfaces: a traditional web-based interface or a game-based interface. We ask each group to manually construct queries to respond to TREC information needs and calculate their resulting recall and precision. Traditional web interface users are provided feedback on their initial queries and asked to use this information to reformulate their original queries. Game interface users are provided with instant scoring and ask to refine their queries based on their scores. We measure the resulting feedback-based improvement on each group and compare the results from human computation techniques to machine-based algorithms. © 2013 Springer-Verlag.

作者： Débora Matos Cezar Reinbrecht Tiago Motta Altamiro Susin PPGC - Graduate Program in Computer Science UFRGS Institute of Informatics Porto Alegre Brazil PPGC - Graduate Program in Computer Science - UFRGS Institute of Informatics Porto Alegre Brazil

Multi-Processors Systems-on-Chip (MPSoCs) are demanding for high performance, low power and high density, and therefore, three-dimensional integrated circuits (3DIC) emerge as a solution to integrate these systems. In order to appropriately interconnect the layers of these systems in terms of flexibility and scalability, a Network-on-Chip (NoC) is typically employed. In this paper, we argue about the scenario of 3D designs, covering all important issues about this new concept. In agreement with all features discussed in this paper, we have proposed a hierarchical 3D topology that meets well the reality of these designs. Experimental results analyze different topologies and show the large benefits in area and power of our proposal.

The electoral system is vital to the democratic process. Several countries have adopted different mechanisms for the electoral process, from paper ballots to electronic voting machines and online voting. There are several benefits of digital polls conducted over the internet, but it also comes with vulnerabilities and forms of manipulation. With the intention of facilitating the development and validation of online voting systems an object-oriented framework was developed for protocols and online elections, where it is possible to implement and test new protocols without the need to develop an entire system.

Incremental validation of NCL hypermedia documents

This paper proposes an incremental, structural and contextual validation method for Nested Context Language (NCL) documents. As part of the proposed method, we define a declarative metalanguage to ensure low coupling between NCL structure and the validator code, which simplifies the validation of new language profiles. Requirements such as incremental processing and multilingual messages are also covered by this work. We present an implementation of this method using component architecture as a proof of concept and also conduct a performance evaluation to compare the traditional and incremental validation approaches. © 2013 The Brazilian computer Society.

Application knowledge base for diabetes such as expert systems has been developed, but generally using conventional methods that have limitations in representing knowledge. Ontology supports the search of data / information by defining the concept of convergent intended by the user. This study using Diabetes Mellitus Classification based diabetes disease diagnosis from World Health Organization Geneva. This system receives input patient data from user. Then, system will build the patient ontology to represent patient knowledge. We are connecting Java applications to Protégé using OWL API. Then, system will calculate the weight of an ontology based on density. This system use JENA Inference Engine and working memory area for reasoning. The system would then do process similarity matching with Ontology Diabetes Mellitus using weighted tree similarity algorithm. Ontology has the highest similarity value will be the proposed diagnosis. Results of this study show that the representation in the form of OWL ontology using weighted ontology and weighted tree similarity algorithm can be used to represent knowledge about diabetes mellitus.

In this paper we address the task of hierarchical bird species identification from audio recordings. We evaluate three types of approaches to deal with hierarchical classification problems: the flat classification approach, the local-model per parent node classifier approach and the global-model hierarchical-classification approach. For the flat and local-model classification approach we employ the classic Naive Bayes algorithm. For the global-model approach we use the Global Model Naive Bayes (GMNB) algorithm. As in the classical Naive Bayes, the algorithm computes prior probabilities and likelihoods, but these computations take into account the hierarchical classification scenario: it assumes that any example which belongs to a given class will also belong to all its ancestor classes. In the current application, the employed class hierarchy is the standard scientific taxonomy of birds used in Biology. In order to deal with the bird songs we obtain features by computing several acoustic quantities from intervals of the audio signal. We conduct three experiments in order to compare the three different approaches to the hierarchical bird species identification problem. Our experimental results show that the use of the GMNB hierarchical classification algorithm outperforms both the flat and local-model approaches (Using the Hierarchical F-measure metric);hence the use of a global-model approach (such as the GMNB) can be a feasible way to improve the classification performance for problems with a large number of classes.
