Shoeprints are a common type of evidence found at crime scenes and are regularly used in forensic investigations. However, their utility is limited by the lack of reference footwear databases that cover the large and growing number of distinct shoe models. Additionally, existing methods for matching crime-scene shoeprints to reference databases…

Researchers are often distressed to discover that the data they wanted to use in their landmark study is not configured in a way that is usable by a Statistical Analysis Software Package (SASP). For example, the data needed may come from two or more sources and it may not be clear to the researcher how to get them combined into one analyzable…

Educational technologists may advance the state of the field by increasing capacity to develop software tools and instructional applications. Presently, few academic programs in educational technology require even a single computer programming course. Further, the educational technologists who develop software generally work independently or in…

The interpretation of single-case data requires systematic visual analysis across and within conditions. Graphs are a vital component for analyzing and communicating single-case design data and a necessary tool for applied researchers and practitioners. Several articles have been published with task analyses for graphing data with the new versions…

Web Access Pattern (WAP), which is the sequence of accesses pursued by users frequently, is a kind of interesting and useful knowledge in practice. Sequential Pattern mining is the process of applying data mining techniques to a sequential database for the purposes of discovering the correlation relationships that exist among an ordered list of…

A study was conducted to propose a research-based model for a longitudinal data research system that addressed recommendations from a synthesis of literature related to: (1) needs reported by the U.S. Department of Education, (2) the twelve mandatory elements that define federally approved state longitudinal data systems (SLDS), (3) the…

This learning activity packet (LAP) contains nine self-paced study lessons that allow students to proceed along a a 43-hour course of study for dBase III Plus at their own pace. The lessons are organized in the following way: objectives, completion standard, performance standard, a list of required materials, unit test, and exercises (applications…

This learning activity packet (LAP) contains five self-paced study lessons that allow students to proceed along a 22-hour course of study for dBase III Plus Advanced at their own pace. It continues the introductory dBase III Plus course. The lessons are organized in the following way: objectives, completion standard, performance standard, a list…

Discusses important factors to consider before deciding on hardware or software to use in building qualitative databases. Examines using the computer to store and retrieve text, store and retrieve graphics, analyze text, analyze graphic materials, distribute data stored on one machine to others, allow researchers access to data from remote sites,…

Enumerates principal management objectives of database management systems (data independence, quality, security, multiuser access, central control) and criteria for comparison (response time, size, flexibility, other features). Conventional database management systems, relational databases, and database machines used for backend processing are…

Discusses the advantages and disadvantages of using dBASE for the storage and retrieval of downloaded bibliographic records, and the problems involved in importing data downloaded from various online systems into dBASE. ASCIIREF, a software program developed to allow users to easily reformat just about any file of ASCII bibliographic records into…

Describes the creation of an interactive retrieval system for electronic numeric files that was developed at Cornell University's (New York) Mann Library. Topics discussed include user characteristics; special data characteristics; quality control; software; hardware; data preparation; database design and construction; interface; subject indexing…

Reviews the state of research in text mining, focusing on newer developments. The intent is to describe the disparate investigations currently included under the term text mining and provide a cohesive structure for these efforts. A summary of research identifies key organizations responsible for pushing the development of text mining. A section…

Articles in this issue of "Global Journal of Computer Science and Technology" include: (1) Input Data Processing Techniques in Intrusion Detection Systems--Short Review (Suhair H. Amer and John A. Hamilton, Jr.); (2) Semantic Annotation of Stock Photography for CBIR Using MPEG-7 standards (R. Balasubramani and V. Kannan); (3) An Experimental Study…

Outlines procedures for the application of data processing technology to media center functions, and explains four steps in designing a database: preliminary design, selection of software, detailed design, and design evaluation. (LRW)
