    • Design and Evaluation of Techniques to Utilize Implicit Rating Data in Complex Information Systems. 

      Kim, Seonho; Fox, Edward A.; Fan, Weiguo; North, Chris; Tatar, Deborah Gail; Torres, Ricardo da Silva (Department of Computer Science, Virginia Polytechnic Institute & State University, 2007-05-01), TR-07-20
      Research in personalization, including recommender systems, focuses on applications such as in online shopping malls and simple information systems. These systems consider user profile and item information obtained from ...
    • ETANA-DL: A Digital Library for Integrated Handling of Heterogeneous Archaeological Data 

      Ravindranathan, Unni; Shen, Rao; Goncalves, Marcos A.; Fan, Weiguo; Fox, Edward A.; Flanagan, James (Department of Computer Science, Virginia Polytechnic Institute & State University, 2004), TR-04-04
      Archaeologists have to deal with vast quantities of information, generated both in the field and laboratory. That information is heterogeneous in nature, and different projects have their own systems to store and use it. ...
    • ETANA-DL: Managing Complex Information Applications - an Archaeology Digital Library 

      Ravindranathan, Unni; Shen, Rao; Goncalves, Marcos A.; Fan, Weiguo; Fox, Edward A.; Flanagan, James (Department of Computer Science, Virginia Polytechnic Institute & State University, 2004), TR-04-05
      Archaeological research results in the generation of large quantities of heterogeneous information managed by different projects using custom information systems. We will demonstrate a prototype Digital Library (DL) for ...
    • EtanaViz: A Visual User Interface to Archaeological Digital Libraries 

      Shen, Rao; Vemuri, Naga Srinivas; Vijayaraghavan, Vidhya; Fan, Weiguo; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2005-10-01), TR-05-14
      Analyzing and hypothesizing are important scientific processes involved in archaeological activity. In this paper, we describe a visual user interface closely coupled with services for archaeological digital libraries, to ...
    • Incremental, Semi-automatic, Mapping-Based Integration of Heterogeneous Collections into Archaeological Digital Libraries: Megiddo Case Study 

      Raghavan, Ananth; Vemuri, Naga Srinivas; Shen, Rao; Goncalves, Marcos A.; Fan, Weiguo; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2005), TR-05-06
      Automation is an important issue when integrating heterogeneous collections into archaeological digital libraries. We propose an incremental approach through intermediary- and mapping-based techniques. A visual schema ...
    • Integration of Heterogeneous Digital Libraries with Semi-automatic Mapping and Browsing: From Formalization to Specification to Visualization 

      Shen, Rao; Vemuri, Naga Srinivas; Raghavan, Ananth; Goncalves, Marcos A.; Rangarajan, Divya; Fan, Weiguo; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2005), TR-05-04
      In this paper, we formalize the digital library (DL) integration problem and propose an overall approach based on the 5S framework. We apply 5S to domain-specific (archaeological) DLs, illustrating our solutions for key ...
    • Intelligent Fusion of Structural and Citation-Based Evidence for Text Classification 

      Zhang, Baoping; Goncalves, Marcos A.; Fan, Weiguo; Chen, Yuxin; Fox, Edward A.; Calado, Pavel; Cristo, Marco (Department of Computer Science, Virginia Polytechnic Institute & State University, 2004), TR-04-16
      This paper investigates how citation-based information and structural content (e.g., title, abstract) can be combined to improve classification of text documents into predefined categories. We evaluate different measures ...
    • A Pattern Analysis of Gene Conversion Literature 

      Lawson, Mark J.; Jiao, Jian; Fan, Weiguo; Zhang, Liqing (Hindawi Publishing Corporation, 2009-11-15)
      Gene conversion is an important biological process that involves the transfer of genetic (sequence) information from one gene to another. This can have a variety of effects on an organism, both short-term and long-term and ...
    • Requirements Gathering and Modeling of Domain-Specific Digital Libraries with the 5S Framework: An Archaeological Case Study with ETANA 

      Shen, Rao; Goncalves, Marcos A.; Fan, Weiguo; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2005), TR-05-07
      Requirements gathering and conceptual modeling are essential for the customization of digital libraries (DLs), to help attend the needs of target com-munities. In this paper, we show how to apply the 5S (Streams, Structures, ...
    • Schema Mapper: A Visualization Tool for DL Integration 

      Raghavan, Ananth; Rangarajan, Divya; Shen, Rao; Goncalves, Marcos A.; Vemuri, Naga Srinivas; Fan, Weiguo; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2005), TR-05-05
      Schema mapping is a challenging problem. It has come to the fore in recent years; there are important applications like database schema integration and, more recently, digital library merging of heterogeneous data. Previous ...
    • What is a Successful Digital Library? 

      Shen, Rao; Vemuri, Naga Srinivas; Fan, Weiguo; Fox, Edward A. (2006-09-18)
      We synthesize diverse research in the area of digital library (DL) quality models, information systems (IS) success and adoption models, and information-seeking behavior models, to present a more integrated view of the ...
