Gomez, Rebecca; Maye, Jessica – Infancy, 2005
We investigated the developmental trajectory of nonadjacent dependency learning in an artificial language. Infants were exposed to 1 of 2 artificial languages with utterances of the form [aXc or bXd] (Grammar 1) or [aXd or bXc] (Grammar 2). In both languages, the grammaticality of an utterance depended on the relation between the 1st and 3rd…

Kim, Jung Hee; Freedman, Reva; Glass, Michael; Evens, Martha W. – Discourse Processes: A Multidisciplinary Journal, 2006
We annotated transcripts of human tutoring dialogue for the purpose of constructing a dialogue-based intelligent tutoring system, CIRCSIM-Tutor. The tutors were professors of physiology who were also expert tutors. The students were 1st year medical students who communicated with the tutors using typed communication from separate rooms. The tutors…

Osterholm, Magnus – Educational Studies in Mathematics, 2006
This study compares reading comprehension of three different texts: two mathematical texts and one historical text. The two mathematical texts both present basic concepts of group theory, but one does it using mathematical symbols and the other only uses natural language. A total of 95 upper secondary and university students read one of the…

Liu, Geoffrey Z. – Journal of the American Society for Information Science, 1997
Presents the Semantic Vector Space Model, a text representation and searching technique based on the combination of Vector Space Model with heuristic syntax parsing and distributed representation of semantic case structures. In this model, both documents and queries are represented as semantic matrices, and retrieval is achieved by computing…

Green, Rebecca – Journal of Documentation, 1995
Presents criteria for an effective syntagmatic relator system and describes how conceptual syntagmatic relationships are expressed in natural language, commenting on the adequacy of such expressions for document retrieval systems. Only one type of expression, a gestalt structure, represented as a frame, conforms to the criteria. (Author/JKP)

Holland, V. Melissa; Kaplan, Jonathan D. – Instructional Science, 1995
Describes the role of natural language processing (NLP) techniques, such as parsing and semantic analysis, within current language tutoring systems. Examines trends, design issues and tradeoffs, and potential contributions of NLP techniques with respect to instructional theory and educational practice. Addresses limitations and problems in using…

Heidorn, P. Bryan – Proceedings of the ASIS Annual Meeting, 1998
Describes a graphic modeling, natural language processing system, VerbalImage, which mimics features of human shape reasoning. Subjects read the same text description and were able to recognize the image generated by the computer from among a series of other computer-generated images. Performance on task was as good as for a control group…

Mai, Jens-Erik – Journal of Documentation, 2001
Explains some major problems related to the subject indexing process and proposes semiotics as a framework for understanding the interpretive nature of the process. Explores the approach to studies of indexing and library and information science suggested by Fairthorne, Blair, Benediktsson, and others. Offers an explanation of what occurs in the…

White, Daniel R.; Joy, Mike S. – Journal on Educational Resources in Computing, 2004
With the increasing levels of access to higher education in the United Kingdom, larger class sizes make it unrealistic for tutors to be expected to identify instances of peer-to-peer plagiarism by eye and so automated solutions to the problem are required. This document details a novel algorithm for comparison of suspect documents at a sentence…

Pasero, Robert; Sabatier, Paul – Computer Assisted Language Learning, 1998
Describes principles underlying ILLICO, a generic natural-language software tool for building larger applications for performing specific linguistic tasks such as analysis, synthesis, and guided composition. Shows to what extent this approach is relevant to the development of computer-assisted language-learning systems. (Author/VWL)
