Real-time virtual humans are less believable than hand-animated characters, particularly in the way they perform gaze. In this paper, we provide the results of an empirical study that explores an observer’s attribution of emotional state to gaze. We have taken a set of low-level gaze behaviors culled from the nonverbal behavior literature; combined these behaviors based on a dimensional model o...

We have witnessed a decade of exploding research interest in multimedia content analysis. The goal of content analysis has been to derive automatic methods for high-level description and annotation. In this paper we will summarize the main research topics in this area and state some assumptions that we have been using all along. We will also postulate the main future trends including usage of l...

This paper analyzes the data now available in Australia’s coordinated Electronic Theses and Dissertations gateway to show the impact of high-level institutional policy decisions on population of the individual repositories. The paper shows that just like research article repositories, voluntary ETD deposition results in repositories collecting only about 15% of the available theses, whereas man...

Prior approaches to sentence compression have taken low level syntactic constraints into account in order to maintain grammaticality. We propose and successfully evaluate a more comprehensive, generalizable feature set that takes syntactic and structural relationships into account in order to sustain variable compression rates while making compressed sentences more coherent, grammatical and rea...

The use of video and audio features for automated annotation of audio-visual data is becoming widespread. A major limitation of many of the current methods is that the stored indexing features are too low-level they relate directly to properties of the data. In this work we apply a further stage of processing that associates the feature measurements with real-world objects or events. The output...

The graphical depiction of uncertainty information is emerging as a problem of great importance. Scientific data sets are not considered complete without indications of error, accuracy, or levels of confidence. The visual portrayal of this information is a challenging task. This work takes inspiration from graphical data analysis to create visual representations that show not only the data valu...

Business Schools are experiencing increased competitive pressures, and one way to differentiate and compete distinctively is through the adoption of innovative uses of information technology. However, the integration of information technology to business education is by no means trivial. This research seeks to provide some guidance about the effect of these new information technologies in the f...

The evidence concerning the level at which learned CP effects occur is complex. The goal of this study was to use a different approach to this question by manipulating the abstractness of the information available for distinguishing pairs of items in an XAB task, and the presence or absence of a short task-filled delay between X and AB. Participants engaged in XAB trials containing a mixture of...
