Maintaining Class Membership Information

Information creation and the notion of membership

Purpose – This article aims to examine a particular sub-set of human information behavior that has been largely overlooked in the library and information science (LIS) literature; how people are socialized to create and use information. Design/methodology/approach – Naturalism and ethnomethodology were used as theoretical frameworks to examine what a group of fifth grade students were taught ab...

Evaluating Category Membership for Information Architecture

We examine two approaches for evaluating category membership within an information taxonomy: card sorting and a simple statistical approach based on the word frequencies of content items. To assess these two approaches, we developed a category structure for a web site based on card sorting. Metrics from the card sorting were obtained to predict problematic tasks. Potentially problematic tasks w...

WAPE - a system for distance learning of programming

A challenging research goal is the development of advanced Web-based educational applications that can offer some amount of adaptivity and intelligence. In the paper the WAPE project being under development as an intelligent and adaptive environment for supporting distance learning of programming is presented. The WAPE system supports users of four types: students, instructors, lecturers and ad...

Set-membership Nonlinear Filtering with Second-order Information

In this paper, we develop a numerically efficient scheme for setmembership prediction and filtering for discrete-time nonlinear systems, that takes into explicit account the effects of nonlinearities via local second-order information. The filtering scheme is based on a classical prediction/update recursion that requires at each step the solution of a convex semidefinite optimization problem. T...
