This paper presents a novel method for automatically detecting and tracking news topics from multimodal TV news data. We propose a multimodal topic and-or graph (MT-AOG) to jointly represent textual and visual elements of news stories and their latent topic structures. An MT-AOG leverages a context-sensitive grammar that can describe the hierarchical composition of news topics by semantic elements...
The study utilized UTAUT (Venkatesh et. al., 2003) to determine technology acceptance of learning management system of Taiwan technical university students. This study used cluster sampling and stepwise regression analysis to determine the relationships among constructs. Research results showed that performance expectancy, attitude toward using technology, facilitating conditions, self-efficacy, and...
In this paper, we present a probabilistic framework for edge and region grouping using conditional random field. Our model is built on a hybrid adjacency graph of atomic region and contour primitives. Unary and pairwise potentials that capture similarity, proximity and curvilinear continuity are defined. Similarity, for both region and edge cues, is measured by likelihood ratios learned from a human...
Even women in technical professional programs in a Taiwan university in 2003 continue to be less receptive than men to uses of instructional computing. The pace of adoption of cyberlearning is influenced by gender factors. Although Taiwan is a semi-conductor world leader, university women in technical universities have not been as receptive as men toward Web-based distance learning. This study used...
