Transformation Based Learning For Specialization Of Generic Event Extractions, Mary D. Taffet, Nancy Mccracken, Eileen Allen, Elizabeth D. Liddy Dec 2002

Transformation Based Learning For Specialization Of Generic Event Extractions, Mary D. Taffet, Nancy Mccracken, Eileen Allen, Elizabeth D. Liddy

School of Information Studies - Faculty Scholarship

As part of our Evidence Extraction and Link Discovery (EELD) project, we proposed to use Transformation Based Learning (TBL) to learn domain-specific specializations for generic event extractions. The primary goal of our learning task was to reduce the amount of human effort required for specializing generic event extractions to domains that are new and specific. Three initial annotation cycles and one annotation review and correction cycle involving a total of 70 documents were completed, with slightly over 32 hours required for the entire annotation effort; where possible, the annotation cycles started with bootstrapped files resulting from the application of TBL …

Concept Tree Based Clustering Visualization With Shaded Similarity Matrices, Bei Yu, Jun Wang, Les Gasser Dec 2002

Concept Tree Based Clustering Visualization With Shaded Similarity Matrices, Bei Yu, Jun Wang, Les Gasser

School of Information Studies - Faculty Scholarship

One of the problems with existing clustering methods is that the interpretation of clusters may be difficult. Two different approaches have been used to solve this problem: conceptual clustering in machine learning and clustering visualization in statistics and graphics. The purpose of this paper is to investigate the benefits of combining clustering visualization and conceptual clustering to obtain better cluster interpretations. In our research we have combined concept trees for conceptual clustering with shaded similarity matrices for visualization. Experimentation shows that the two interpretation approaches can complement each other to help us understand data better.

Commercial Websites And The Use Of Classification Schemes: The Case Of Amazon.Com. In Lopez-Huertas, Maria J. Challenges In Knowledge Represantation An Organization For The 21st Century: Intergration Of Knowledge Across Boundaries., Barbara H. Kwasnik Jul 2002

The structure and use of the classification for books on the Amazon.com website are described and analyzed. The contents of this large website are changing constantly and the access mechanisms have the main purpose of enabling searchers to find books for purchase. This includes finding books the searcher knows about at the start of the research, as well as those that might present themselves in the course of searching and that are related in some way. Underlying the many access paths to books is a classification scheme comprising a rich network of terms in an enumerative and multihierarchical structure.

Information Literacy Instruction In Higher Education: Trends And Issues, Abby Kasowitz-Scheer, Michael Pasqualoni Jun 2002

Information Literacy Instruction In Higher Education: Trends And Issues, Abby Kasowitz-Scheer, Michael Pasqualoni

Libraries' and Librarians' Publications

Students today face a daily explosion of information resources and the challenge of using these resources effectively and responsibly. Information literacy instruction (ILI) requires a shift in focus from teaching specific information resources to a set of critical thinking skills involving the use of information. ILI in an academic setting includes a variety of instructional approaches, such as course-related library instruction sessions, course-integrated projects, online tutorials, and stand-alone courses. Those running formal ILI programs consider curricular objectives, invoking combinations of instructional solutions over a period of time. This ERIC Digest examines characteristics of successful programs, presents specific examples of approaches …

The Digital Library: A Biography, Suzanne E. Thorin, Daniel Greenstein Jan 2002

The Digital Library: A Biography, Suzanne E. Thorin, Daniel Greenstein

Libraries' and Librarians' Publications

The idea for the study took shape in a New York City steakhouse where four DLF directors met to reflect on the new roles and responsibilities that were emerging for their libraries as they entered an increasingly networked digital age.1 Realizing that lessons from the past were easier and perhaps more predictive than prognostications about the future, they suggested that a study of DLF member programs would reveal the history, aims, organization, and immediate challenges in their libraries The study progressed quickly, following the development of a lengthy (104-question) survey that was received and completed without complaint at DLF member …

Ontological Representation Of Learning Objects, Jian Qin, Christina Finneran Jan 2002

Ontological Representation Of Learning Objects, Jian Qin, Christina Finneran

School of Information Studies - Faculty Scholarship

Many of the existing metadata standards use content metadata elements that are coarse-grained representations of learning resources. These metadata standards limit users ’ access to learning objects that may be at the component level. The authors discuss the need for component level access to learning resources and provide a conceptual framework of the knowledge representation of learning objects that would enable such access.

Question Answering: Cnlp At The Trec-2002 Question Answering Track, Anne R. Diekema, Jiangping Chen, Nancy Mccracken, Necati Ercan Ozgencil, Mary D. Taffet Jan 2002

Question Answering: Cnlp At The Trec-2002 Question Answering Track, Anne R. Diekema, Jiangping Chen, Nancy Mccracken, Necati Ercan Ozgencil, Mary D. Taffet

This paper describes the retrieval experiments for the main task and list task of the TREC-2002 question-answering track. The question answering system described automatically finds answers to questions in a large document collection. The system uses a two-stage retrieval approach to answer finding based on matching of named entities, linguistic patterns, keywords, and the use of a new inference module. In answering a question, the system carries out a detailed query analysis that produces a logical query representation, an indication of the question focus, and answer clue words.
