Projects |
- YODAS : 2022 - Present
- The purpose of Youngname Old Document Archive System (YODAS) is to provide a digital data management infrastructure for aggregating, organizing, and disseminating ancient document data for research communities as well as the general public. In that regard, YODAS extends the conventional archival functions of collection and preservation to focus on information dissemination and data reuse. To promote data reuse, YODAS 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.
- KoDDAS : 2019 - Present
- 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.
- JISTaP : 2002 - Present
- Journal of Information Science Theory and Practice (JISTaP) is an ongoing joint project with Korea Institute of Science and Technology Information (KISTI) for publishing and managing the international journal "Journal of Information Science Theory and Practice". The project, whose aim is to establish a roadmap for creating and maintaining a renowned international journal, involves implementing effective strategies and robust procedures for high quality manuscript submission and peer-review process as well as prototyping and streamlining an open access publication platform.
- CiteSearch : 2005 - Present
- 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.
- IASSJ : 2017 - 2019
- Integrated Analysis of Social Science Journals (IASSJ) is a National Research Foundation project that explores development strategies for social science journals in Korea. The project investigates differences between internationally indexed journals and domestic journals in Korea in a multi-faceted way that range from surveys and interviews of scholars to analysis of journal editorial boards as well as publication data.
- TREC : There are multiple Tracks under TREC (Text Retrieval Conference) domain
-
Blog Track : 2006 - 2008
A new track in TREC 2006. The goal of the Blog track is to explore information seeking behavior in the blogosphere. The task of Blog track is to retrieve blog postings that express opinion about a given target. A subtask is to determine the opinion polarity (i.e., positive, negative, mixed).SPAM Track : 2005 - 2006
A new track in TREC 2005. The goal of the SPAM track is to provide a standard evaluation of current and proposed spam filtering approaches, thereby laying the foundation for the evaluation of more general email filtering and retrieval tasks. The task of SPAM track is to create an automatic spam filter that classifies a chronological sequence of email messages as SPAM or HAM (non-spam). The spam filter is run on several email sequences, some public and some private. The performance of the filter is measured with respect to gold standard judgements by a human assessor.Genomics Track : 2004
Due to the explosion of new data-intensive technologies for sequencing and examining genomes and proteomes during the '90s, the TREC Genomics Track was started in 2003. Its goal is to explore new methods for efficiently discovering and retrieving documents associated with the function of various genes and proteins within a given biology domain or 'sub-area'.HARD Track : 2004 - 2005
The goal of HARD (High Accuracy Retrieval from Documents) is to achieve high accuracy retrieval from documents by leveraging additional information about the searcher and/or the search context, through techniques such as passage retrieval, and using very targeted interaction with the searcher.Robust Track : 2003 - 2005
The Robust Retrieval Track was a new track introduced in TREC 2003. The goal of the track is to improve the consistency of retrieval technology by focusing on poorly performing topics. In addition, the tracks brings back a classic, ad hoc retrieval task to TREC that provides a natural home for new participants.Web Track : 2003 - 2004
The goals of Web Track are:
1. To investigate methods for effective topic distillation: Finding a set of the best home pages, given a broad query.
2. To investigate methods for effective navigational search, with a mixture of home page and named page queries: Finding a particular page desired by the user.
3.To increase the available queries/judgments for the .GOV test collection. - VCoB : 2004 - Present
- The aim of the Virtual Collection Builder (VCoB) project is to develop an adaptive, interactive agent for building and maintaining a virtual collection of Web documents.
- VCob approach 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.
- DGov : 2004 - 2006
- The aim of the Digital Government (DGov) project is to develop a more efficient and effective approach to organizing the U.S. Government websites that can facilitate the access and enhance the retrieval of government information.
- DGov approach will combine information retrieval (e.g. keyword search) and information organization methods (e.g. Semantic Web) to optimize the government information discovery process on the Web.
- jiTTDL : 2004 - 2007
- JiTTDL is an NSF-funded project at US Air Force Academy that will develop the digital library for Just-in-Time pedagogical resources. Dr. Elin Jacob and myself are consultants on JiTTDL project, where we are employing CSKD-based approaches to construct a prototype digital library system.
- CSKD : 2003 - 2009
- The Classification-based Search and Knowledge Discovery (CSKD) project aims to leverage an existing body of manually classified documents to enhance information retrieval and knowledge discovery on the Web. CSKD research, which explores methods of leveraging both the ontological and link-structural knowledge embedded in classified corpora of Web documents for searching and organizing the Web, is a multi-dimensional project that entails investigations in such area as machine learning, classification, clustering, link analysis, and fusion.
