this study aims to investigate the relationship between information literacy, computer self-efficacy and academic performance in a population of 1054 of ba and ma students of psychology and educational sciences faculty of tehran university. the data are collected in a sample of 283 students (103 ba and 180 ma); selected using cochran's sampling formula. these students answered mittermeyer ...

This paper reports our multimedia information retrieval experiments carried out for the ImageCLEF track (ImageCLEFwiki). The task is to answer to user information needs, i.e. queries which may be composed of several modalities (text, image, concept) with ranked lists of relevant documents. The purpose of our experiments is twofold: firstly, our overall aim is to develop a multimedia document mo...

Information Filtering is concerned with filtering data streams in such a way as to leave only pertinent data (information) to be perused. When the data streams are produced in a changing environment (as most if not all are) the filtering has to adapt too in order to remain effective. Adaptive Information Filtering (AIF) is concerned with filtering in changing environments. The changes may occur...

The Information Source Adapter Platform (or ISA Platform, for short) is a set of practical enabling technologies for developing intelligent information systems. The platform provides an infrastructure for building lightweight interfaces to existing resources that can be composed automatically using means-ends analysis. The ISA Platform enables developers to rapidly create new and innovative app...

Emergent self-organizing maps (ESOMs) and k-means clustering are used to cluster counties in each of the states of Florida, Pennsylvania, and Ohio by demographic data from the 2010 United States census. The counties in these clusters are then analyzed for how they voted in the 2008 U.S. Presidential election, and political strategies are discussed that target demographically similar geographica...

Clustering is an important concept for analysis of data in GIS. Due to the potentially large amount of data in such systems, the time complexity for clustering algorithms is critical. K-means is a popular clustering algorithm for large scale systems because of its linear complexity. However, this requires a priori knowledge of the number of clusters and the subsequent selection of their centroi...
