WIDIT Research

Web Information Discovery Integrated Tool (WIDIT) research aims to develop an integrated approach to Web information discovery by leveraging multiple sources of evidence (e.g., text, hyperlink, ontology), combining complementary methods (e.g., information retrieval, natural language processing, machine learning, knowledge organization), and optimizing the integration of human intelligence with machine processing power. WIDIT laboratory houses the collaborative research projects of three faculty members and numerous students.
KoDDAS Project: 2019-present, Co-PI
Korean Diaspora Digital Archive System (KoDDAS) is a 6-year National Research Foundation project to develop an integrated database system that utilizes augumented-intelligence and faceted classification. The purpose of KoDDAS is to provide a digital data management infrastructure for aggregating, organizing, and disseminating Korean Diaspora data for research communities as well as the general public. In that regard, KoDDAS extends the conventional archival functions of collection and preservation to focus on information dissemination and data reuse. To promote data reuse, KoDDAS will implement an integrated online database system that contains not only the raw data, but also the contextual and structural metadata that can facilitate the understanding and analysis of Korean Diaspora data.
TREC Project: 2002-2009, Project Director
TREC project investigates cutting-edge information retrieval strategies that accommodate a variety of data environments and search tasks. TREC project is responsible for developing core components of the WIDIT system architecture, which are utilized in other WIDIT projects, as well as TREC experiments.
CiteSearch Project: 2005-present, Project Director
CiteSearch project, a component of VCoB, develops a multi-faceted fusion approach to information quality assessment that employs a range of citation-based methods to analyze data from multiple sources. The CiteSearch system currently consists of the sf-vcob component, which harvests and analyzes citation data of faculty publications, and the mini-vcob component, which collects and organizes scholarly publications and associated citation data on a given topic.
TREC Project: 2002-2009, Project Director
TREC project investigates cutting-edge information retrieval strategies that accommodate a variety of data environments and search tasks. TREC project is responsible for developing core components of the WIDIT system architecture, which are utilized in other WIDIT projects, as well as TREC experiments.
VCoB Project: 2003-2009, Project Director
Virtual Collection Builder (VCoB) project aims to develop an adaptive and interactive agent for building and maintaining a virtual collection of Web documents. VCoB will employ a wide array of methods from content analysis, citation analysis, machine learning, and information retrieval to collect, organize, and maintain a searchable and browsable collection of documents that are custom-taylored to the needs and preferences of individual users.
CSKD Project: 2003 - 2009, Project Co-Director with E.K. Jacob
The Classification-based Search and Knowledge Discovery (CSKD) research explores methods of leveraging both the ontological and link-structural knowledge embedded in classified corpora of Web documents for searching and organizing the Web. CSKD is a multi-dimensional project that entails investigations in such area as machine learning, classification, clustering, link analysis, and fusion.
JiTTDL Project: 2004 - 2007, Project Co-Director with E.K. Jacob
Just-in-Time Teaching Digital Library (JiTTDL) is an NSF-funded project at US Air Force Academy to develop the digital library for Justin-in-Time pedagogical resources, where CSKD-based approaches were employed to construct a prototype digital library system.
DGov Project: 2004 - 2006, Project Co-Director with L. Meho
Digital Government (DGov) project investigates an efficient and effective approach to organizing the U.S. Government websites that can facilitate the access and enhance the retrieval of government information.i The DGoV project became inactive when a major government initiative to restructure FirstGov.gov to USA.gov began in 2007.
