Awaida, Sameh M.; Mahmoud, Sabri A. – Educational Research and Reviews, 2012
In this paper we present the state of the art in writer identification and verification of handwritten text. In addition, a special and extensive survey of writer identification and verification of Arabic handwritten text is also included. Different feature extraction techniques are addressed showing the different research groups' efforts as well…

Wilder, John; Feldman, Jacob; Singh, Manish – Cognition, 2011
This paper investigates the classification of shapes into broad natural categories such as "animal" or "leaf". We asked whether such coarse classifications can be achieved by a simple statistical classification of the shape skeleton. We surveyed databases of natural shapes, extracting shape skeletons and tabulating their…

Kleban, James Theodore – ProQuest LLC, 2010
The Internet Age has seen the emergence of richly annotated image data collections numbering in the billions of items. This work makes contributions in three primary areas which aid the management of this data: image representation, efficient retrieval, and annotation based on content and metadata. The contributions are as follows. First,…

Bell, D. A.; Guan, J. W. – Journal of the American Society for Information Science, 1998
Rough set theory is a new mathematical tool to deal with vagueness and uncertainty. Computational methods are presented for using rough sets to identify classes in datasets, finding dependencies in relations, and discovering rules which are hidden in databases. The methods are illustrated with a running example from a database of car test results.…

Ribeiro-Neto, Berthier; Laender, Alberto H. F.; de Lima, Luciano R. S. – Journal of the American Society for Information Science and Technology, 2001
Evaluates the retrieval performance of an algorithm that automatically categorizes medical documents, which consists in assigning an International Code of Disease (ICD) based on well-known information retrieval techniques. Reports on experimental results that tested precision using a database of over 20,000 medical documents. (Author/LRW)

Hooley, Paul; Chilton, Ian J.; Fincham, Daron A.; Burns, Alan T.; Whitehead, Michael P. – Bioscience Education e-Journal, 2007
There is currently much interest in ascribing outcomes to Masters (M) level programmes. It is particularly difficult to define M level outcomes in bioinformatics for students on non-specialist programmes. An approach is described that attempts to discriminate undergraduate from M level in a data-mining exercise. Differentiation of level is based…

Wittebols, James H. – 1986
Recommendations designed to assist states in the creation of meaningful definitions of types of schools and students for use in the Council of Chief State School Officers' Education Data Improvement Project are presented. The Project's goals are to promote and facilitate the reform and refinement of the National Center for Education Statistics'…

Fuchs, Douglas; Fuchs, Lynn S.; Compton, Donald L. – Learning Disability Quarterly, 2004
This article first describes two types of assessment (problem solving and standard treatment protocol) within a "responsiveness-to-instruction" framework to identify learning disabilities. It then specifies two necessary components (measures and classification criteria) to assess responsiveness-to-instruction, and present pertinent findings from…

Hodapp, Robert M.; Urbano, Richard C.; So, Stephanie A. – Down Syndrome Research and Practice, 2006
In this paper, we utilise an approach drawn from the field of epidemiology to explore what is known and unknown about young children with Down syndrome and their families. After describing what we mean by an epidemiological approach, we review basic findings for children with intellectual disabilities, as well as challenges to performing such…

Larson, Ray R. – Journal of the American Society for Information Science, 1992
Discusses subject searching problems in online library catalogs; explains advanced information retrieval (IR) techniques; and describes experiments conducted on a test collection database, CHESHIRE (California Hybrid Extended SMART for Hypertext and Information Retrieval Experimentation), which was created to evaluate IR techniques in online…

Narin, Francis; And Others – Evaluation Review, 1994
Theory behind modern evaluative bibliometric techniques is reviewed at three levels: (1) policy application; (2) strategic analysis; and (3) tactical analysis. New techniques developed at each level and limitations of each approach are discussed. At all levels, the process begins with assembling data and then moves to a data-based evaluation. (SLD)

Rossman, Gretchen B.; Salzman, Julianne – 1995
Initial steps in a long-term effort to identify and analyze evaluations of inclusive education programs are discussed. Three activities have been initiated to survey current evaluation practice. A literature search revealed that "inclusion" is not yet a description for the ERIC system, but that some papers have been published on the topic. A…
