Inductive Model Generation for Text Classification Using a Bipartite Heterogeneous Network

引用

Journal of Computer Science & Technology 2014年第3期29卷 361-375页

作者： Rafael Geraldeli Rossi Alneu de andrade lopes Thiago de Paulo Faleiros Solange oliveira Rezende Institute of Mathematics and Computer Science University of So PauloSo CarlosBrasil

Algorithms for numeric data classification have been applied for text classification. Usually the vector space model is used to represent text collections. The characteristics of this representation such as sparsity and high dimensionality sometimes impair the quality of general-purpose classifiers. Networks can be used to represent text collections, avoiding the high sparsity and allowing to model relationships among different objects that compose a text collection. Such network- based representations can improve the quality of the classification results. One of the simplest ways to represent textual collections by a network is through a bipartite heterogeneous network, which is composed of objects that represent the documents connected to objects that represent the terms. Heterogeneous bipartite networks do not require computation of similarities or relations among the objects and can be used to model any type of text collection. Due to the advantages of representing text collections through bipartite heterogeneous networks, in this article we present a text classifier which builds a classification model using the structure of a bipartite heterogeneous network. Such an algorithm, referred to as IMBHN （Inductive Model Based on Bipartite Heterogeneous Network）, induces a classification model assigning weights to objects that represent the terms for each class of the text collection. An empirical evaluation using a large amount of text collections from different domains shows that the proposed IMBHN algorithm produces significantly better results than k-NN, C4.5, SVM, and Naive Bayes algorithms.

Absence of galectin-3 attenuates neuroinflammation improving functional recovery after spinal cord injury

Neural Regeneration Research 2016年第1期11卷 92-93页

After spinal cord injury （SCI）, a cascade of events begins. At first, there is physical damage with disruption of the blood-brain barrier （BBB） and the integrity of the nervous tissue. The disruption of central ner- vous system （CNS） BBB alters the endothelial permeability, the protein and chemokines expression and the propensity to release in situ inflam- matory cytokines, overcoming anti-inflammatory signals, facilitating the attraction and entry of immune system cells into the injured spinal cord parenchyma （Gaudet et al., 2011）. As a result, there is a neuroin- flammatory response with changes in blood flow, edema, cell infiltra- tion, apoptosis and release of axonal growth inhibitory factors. Nerve function loss occurs when the nerve impulse propagation is interrupted and do not reach its target. This disorder encompasses neuron and glia apoptosis, accompanied by Wallerian degeneration of disconnected axons, and CNS cells exposure to a hostile microenvironment that hampers axon regeneration （Mautes et al., 2000; Harkey et al., 2003）.

Multidimensional Projections for Visual Analysis of Social Networks

Journal of Computer Science & Technology 2012年第4期27卷 791-810页

作者： Rafael Messias Martins Gabriel Faria Andery Henry Heberle Fernando Vieira Paulovich Alneu de andrade lopes Helio Pedrini Rosane Minghim Institute of Mathematics and Computer Science University of Sao PauloSao Carlos 13566-590Brazil CPM Braxis Capgemini Sao Paulo 04543-900Brazil Institute of Computing University of CampinasCampinas-SP 13083-852Brazil

Visual analysis of social networks is usually based on graph drawing algorithms and tools. However, social networks are a special kind of graph in the sense that interpretation of displayed relationships is heavily dependent on context. Context, in its turn, is given by attributes associated with graph elements, such as individual nodes, edges, and groups of edges, as well as by the nature of the connections between individuals. In most systems, attributes of individuals and communities are not taken into consideration during graph layout, except to derive weights for force-based placement strategies. This paper proposes a set of novel tools for displaying and exploring social networks based on attribute and connectivity mappings. These properties are employed to layout nodes on the plane via multidimensional projection techniques. For the attribute mapping, we show that node proximity in the layout corresponds to similarity in atgribute, leading to easiness in locating similar groups of nodes. The projection based on connectivity yields an initial placement that forgoes force-based or graph analysis algorithm, reaching a meaningful layout in one pass. When a force algorithm is then applied to this initial mapping, the final layout presents better properties than conventional force-based approaches. Numerical evaluations show a number of advantages of pre-mapping points via projections. User evaluation demonstrates that these tools promote ease of manipulation as well as fast identification of concepts and associations which cannot be easily expressed by conventional graph visualization alone. In order to allow better space usage for complex networks, a graph mapping on the surface of a sphere is also implemented.
