  • Applying Graph Layout Techniques to Web Information Visualization and Navigation 
    Lai Wei; Huang Xiaodi; Nguyen Quang Vinh; Huang Mao (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    Graph layout techniques have been developed for many years, there is a few applying to real world applications. This paper presents an application of applying graph layout techniques in web information visualization ...
  • Attributed graph visualization of collaborative workspaces 
    Nguyen Quang Vinh; Huang Mao; Hintz Thomas (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2005)
    Collaborative workspaces are becoming increasingly commonplace, particularly in large, distributed organizations where virtual teams formed in order to jointly carry out collaborative project work. Typical collaborative ...
  • A Combined Visualisation of Multiple Relational Structures in Shared Collaborative Workspaces 
    Nguyen Quang Vinh; Huang Mao (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2004)
    This paper presents a new approach for visualizing multiple relationships among collaborative objects in shared workspaces. Our new visualization provides users with a Graphical User Interface (GUI) for viewing, analyzing ...
  • DualView: A focus+context technique for navigating large graphs 
    Nguyen Quang Vinh; Huang Mao (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2005)
    This paper presents a fast and efficient focus+context technique, called DualView for navigating large graphs/hierarchies which are usually displayed in a high-density manner. The DualView includes two transformations: ...
  • A Fast Algorithm for Balanced Graph Clustering 
    Huang Mao; Nguyen Quang Vinh (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    Scalability problem is a long-lasting challenge for both information visualization and graph drawing communities. Available graph visualization techniques could perform well for small or medium size graphs but they are ...
  • A Kernel-Based Algorithm for Multilevel Drawing Web Graphs 
    Lai Wei; Zhang Di; Huang Xiaodi; Huang Mao; Nguyen Quang Vinh (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    A Web graph refers to the graph that models the hyperlink relations between Web pages in the WWW, where a node represents a URL and an edge indicates a link between two URLs. A Web graph is normally a very huge graph. ...
  • Navigating Large Clustered Graphs with Triple-Layer Display 
    Huang Mao; Nguyen Quang Vinh (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    This paper presents a technique for navigating large clustered graphs with triple-layer display. Although our navigation and interaction technique can be applied independently to any graph layout algorithms, in ...
  • Space Efficient Clustered Visualization of Large Graphs 
    Huang Mao; Nguyen Quang Vinh (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    This paper proposes a new technique for visualizing large graphs of several ten thousands of vertices and edges. To achieve the graph abstraction, a hierarchical clustered graph is extracted from a general large graph ...
  • A technique for visualizing dihedral of large protein sequences 
    Huang Mao; Nguyen Quang Vinh; Zhang Kang; Qian Yu (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)
    This paper presents a clustering and visualization technique for analyzing dihedral angles of large protein sequences. The clustering is used for discovering and grouping those similar dihedrals while the visualization can ...
  • Three-Dimensional EncCon Tree 
    Huang Mao; Nguyen Quang Vinh; Lai Wei; Huang Xiaodi (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    This paper describes a three-dimensional extension of a enclosure+connection layout technique, called EncCon tree. The three-dimensional visualization includes layout and navigation. The layout algorithm directly ...
  • A visualization model for web sitemaps 
    Huang Mao; Nguyen Quang Vinh; Zhang Kang; Yen I (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)
    This paper describes a space-efficient visualization model that automatically crawls through a website and visualizes its sitemap. This model can be used especially for displaying and navigating a very large website in ...
  • Visualization of Large Citation Networks with Space-Efficient Multi-Layer Optimization 
    Huang Mao; Nguyen Quang Vinh (Macquarie Scientific Publishing, 2007)
    This paper describes a technique for visualizing large citation networks (or bibliography networks) using a space-efficient multi-layer optimization visualization technique. Our technique first use a fast clustering ...
