It is preferable for business professionals to develop web applications which must be modified frequently based on their needs. A website for matching is a typical example because various matching websites for C2C (Consumer to Consumer) have recently been opened in relation to the "sharing economy". In our case studies on end-user…

A design and application of adaptive online exam system are carried out in this paper. Adaptive exam systems determine different question sets automatically and interactively for each student and measure their competence on a certain area of discipline instead of comparing their gains with each other. Through an adaptive exam technique, a…

Statistical clustering is critical in designing scalable image retrieval systems. This paper presents a scalable algorithm for indexing and retrieving images based on region segmentation. The method uses statistical clustering on region features and IRM (Integrated Region Matching), a measure developed to evaluate overall similarity between images…

This paper discusses a generic query tool that enables an end user to query a metadata store through filters that impose search criteria on attributes. The Metadata Query Tool (MQT) is generic in the sense that it dynamically creates its user interface, based on configuration files that define the metadata scheme and the query functionalities.…

Each semester at Miami University (Ohio) the secretaries struggle to update the Campus Directory database in order to print the campus telephone and office/class hours directory. It is a time-consuming process and the directory is usually late and out-of-date by the time it is printed. The university's Computer Services Manager has created a Web…

As new users from the non-technical community are attracted to multimedia (MM) computing, it becomes necessary to design a convenient and easy-to-understand logical structure that facilitates data transfer from the MM data repository to MM applications. A recently introduced layered formalism, which describes MM applications in terms of the data…

This study investigated the effects of interface tools and learner cognitive styles on performance in searches for information within a hypermedia database. The subjects, 75 students in a university English as a Second Language (ESL) program, were blocked for field dependence and assigned to four treatments which differed by the search tool…

This paper proposes a model for a general interface between people and Computer Algebra Systems (CAS). The main features in the CAS interface are data navigation and the possibility of accessing powerful remote machines. This model is based on the idea of session management, in which the main engine of the tool enables interactions with the…

The goal of the Carnegie Mellon Online project is to build an infrastructure for delivery of courses via the World Wide Web. The project aims to deliver educational content and to assess student competency in support of courses across the Carnegie Mellon University (Pennsylvania) curriculum and beyond, thereby providing an asynchronous,…

The rapid adoption of information technology and ubiquitous networking has transformed the research and education landscape. Central to this transformation are scientific and engineering digital data collections. The life cycle management challenges associated with these intellectual assets are substantial. This is a report of a two-day workshop…

This paper presents an information retrieval system for delivering educational visual materials through the World Wide Web. The system is designed to meet the following user requirements: lecturers prefer direct control over their visual resources; lecturers demand a browser-based interface that will allow them to create and modify their online…
