In this article, the research of multimedia teaching video content feature extraction is carried out. According to the file structure, data type, and storage mechanism of the teaching video, a program is developed to automatically extract the structural features of the teaching video content, and a storage and retrieval database is established.…

Although widely used, the SCORM metadata model for content aggregation is difficult to be used by educators, content developers and instructional designers. Particularly, the identification of contents related with each other, in large repositories, and their aggregation using metadata as defined in SCORM, has been demanding efforts of computer…

An ontology expresses a common understanding of a domain that serves as a basis of communication between people or systems, and enables knowledge sharing, reuse of domain knowledge, reasoning and thus problem solving. In Technology-Enhanced Learning, especially in Intelligent Tutoring Systems and Adaptive Learning Environments, ontologies serve as…

Over the past thirty years, clinical research has benefited substantially from the adoption of electronic medical record systems. As deployment has increased, so too has the number of researchers seeking to improve the overall analytical environment by way of tools and models. Although much work has been done, there are still many uninvestigated…

There was a time when school districts showed little interest in storing or backing up their data to remote servers. Nothing seemed less secure than handing off data to someone else. But in the last few years the buzz around cloud storage has grown louder, and the idea that data backup could be provided as a service has begun to gain traction in…

Even in the age of Google, digital repositories can add tremendous value to an institution. Yet creating and maintaining these collections is no small task. Digital repository advocates will concede that the challenges in building and maintaining these collections can daunt even the most intrepid supporters. Three repository directors share their…

This document provides recommendations for request for proposal (RFP) and contract language that state education agencies can use to specify their requirements for access to test item banks. An item bank is a repository for test items and data about those items. Item banks are used by state agency staff to view items and associated data; to…

An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…

This paper provides a comprehensive set of guidelines for building an online course based on the e-learning standards. It discusses the steps that should be followed to build a digital repository that facilitates the storage, retrieval, and reuse of the learning resources that comprise an online course in a standard way. The paper also examines…

This book addresses the history, theory, and practices of the organization of recorded information. Chapter 1, "Organization in Human Endeavors," looks at the basic human need to organize and how it is approached in various environments. Chapter 2, "Retrieval Tools," is concerned with the formats and functions of basic…

Learning Objects Metadata (LOM) aims at describing educational resources in order to allow better reusability and retrieval. In this article we show how additional inference rules allows us to derive additional metadata from existing ones. Additionally, using these rules as integrity constraints helps us to define the constraints on LOM elements,…

Institutional researchers play a key role in an environment where data warehouses are used to store and retrieve vast amounts of data. Along with the benefits of increased access for more users, improved reporting capabilities, and less reliance on centralized information, come questions of appropriate data usage, data access and security,…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
