Deane, Paul; Sheehan, Kathleen M.; Sabatini, John; Futagi, Yoko; Kostin, Irene – Scientific Studies of Reading, 2006
One source of potential difficulty for struggling readers is the variability of texts across grade levels. This article explores the use of automatic natural language processing techniques to identify dimensions of variation within a corpus of school-appropriate texts. Specifically, we asked: Are there identifiable dimensions of lexical and…

Green, Georgia M. – 1995
A variety of techniques for collecting and analyzing information about the natural use of natural languages is surveyed, emphasizing the importance of recognizing the properties of a research task that make a given technique more or less suitable to it rather than comparing techniques globally and ranking them absolutely. An initial goal is to…

Kim, Dongseok; Jung, Hanmin; Lee, Gary Geunbae – Information Processing & Management, 2003
Presents a new extraction pattern, modified Document Type Definition (mDTD), which relies on analytical interpretation to identify extraction target from the contents of Web documents. Experiments with 330 Korean and 220 English Web documents on audio and video shopping sites yielded an average extraction precision of 91.3% for Korean and 81.9%…

Pritchard-Schoch, Teresa – Online, 1995
Compares two natural language processing search engines, WIN (WESTLAW Is Natural) and FREESTYLE, developed by LEXIS. Legal issues in natural language queries were presented to identical libraries in both systems. Results showed that the editorials enhanced relevance; a search would be more thorough using both databases; and if only one system were…

Weeber, Marc; Klein, Henny; de Jong-van den Berg, Lolkje T. W.; Vos, Rein – Journal of the American Society for Information Science and Technology, 2001
Proposes a two-step model of discovery in which new scientific hypotheses can be generated and subsequently tested. Applying advanced natural language processing techniques to find biomedical concepts in text, the model is implemented in a versatile interactive discovery support tool. This tool is used to successfully simulate Don R. Swanson's…

Chowdhury, Gobinda G. – Library Trends, 1999
Reviews template mining research and shows how templates are used in World Wide Web search engines and metasearch engines for helping end-users generate natural language search expressions. Potential areas of application of template mining for extraction of information from digital documents are highlighted, and how such applications are used is…

Craig, Scotty D.; Graesser, Arthur C.; Sullins, Jeremiah; Gholson, Barry – Journal of Educational Media, 2004
The role that affective states play in learning was investigated from the perspective of a constructivist learning framework. We observed six different affect states (frustration, boredom, flow, confusion, eureka and neutral) that potentially occur during the process of learning introductory computer literacy with AutoTutor, an intelligent…

Wacholder, Nina; Evans, David K.; Klavans, Judith L. – 2001
The potential of automatically generated indexes for information access has been recognized for several decades, but the quantity of text and the ambiguity of natural language processing have made progress at this task more difficult than was originally foreseen. Recently, a body of work on development of interactive systems to support phrase…

Turtle, Howard; Flood, James – Information Processing & Management, 1995
Discusses two query evaluation strategies used in large text retrieval systems: (1) term-at-a-time; and (2) document-at-a-time. Describes optimization techniques that can reduce query evaluation costs. Presents simulation results that compare the performance of these optimization techniques when applied to natural language query evaluation. (JMV)

Strzalkowski, Tomek – Information Processing & Management, 1995
Describes an information retrieval system in which advanced natural language processing is used to enhance the effectiveness of term-based document retrieval by preprocessing the documents; discovering interterm dependencies and build a conceptual hierarchy specific to database domain; and processing the user's natural language requests into…

Maybury, Mark T. – Information Processing & Management, 1995
Describes and evaluates a system that selects key information from an event database by reasoning about event frequencies, frequencies of relations between events, and domain-specific importance measures. The system aggregates similar information and plans a summary tailored to a stereotypical user. (AEF)

Nerbonne, John; Dokter, Duco; Smit, Petra – Computer Assisted Language Learning, 1998
Reports on GLOSSER, an intelligent assistant for Dutch students learning to read French, and discusses the position of natural-language processing within computer-assisted instruction, using GLOSSER as an example. (Author/VWL)

Bradshaw, Shannon; Hammond, Kristian – Proceedings of the ASIS Annual Meeting, 1999
Rosetta, an indexing and retrieval system indexes papers in a collection based on the way they have been described when referenced by other papers in the collection. Using Rosetta, simple natural language queries retrieve high-precision results in which descriptions based on citations clearly summarize retrieved papers, allowing users to quickly…

Graesser, Arthur C.; Person, Natalie K.; Jackson, G. Tanner; Toth, Jozsef A. – International Journal on E-Learning, 2004
The Human Use Regulatory Affairs Advisor (HURAA) is an Internet facility that provides help and training on the ethical use of human subjects in research, based on documents and regulations in United States Federal agencies. HURAA has a number of standard features of conventional web facilities and computer-based training, such as hypertext,…

Weber-Russell, Sylvia; LeBlanc, Mark D. – Journal of the Learning Sciences, 2004
"Learning by doing" in pursuit of real-world goals has received much attention from education researchers but has been unevenly supported by mathematics education software at the elementary level, particularly as it involves arithmetic word problems. In this article, we give examples of doing-oriented tools that might promote children's ability to…
