We propose heading-aware methods of generating search result snippets of web pages. A heading is a brief description of the topic of its associated sentences. Some existing methods give priority to sentences containing many words that also appear in headings when selecting sentences to be included in snippets with limited length. However, according to our observation, words in heading are very ...

A central theme in previous studies of heading judgements has been whether the retinal flow field can be decomposed to recover the translation component of locomotion when flow also contains the effects of gaze rotation. We explored not just the effect of moving gaze, but also moving attention away from the locomotor path by presenting the case of fixating a road sign and completing different a...

Sense-of-direction (SOD) has been described as a system that tracks the body’s facing direction relative to an environmental reference frame (allocentric heading). To study this system, Sholl, Kenny, and DellaPorta (2006) developed a headingrecall task and found that task accuracy correlated highly with self-reported SOD measures. This study attempts to replicate and extend their findings, by i...

hybrid rice varieties are potentially higher yielding than the best inbred varieties and perform better under adverse conditions of drought and salinity. one of the major impediments for seed production of hybrid rice is incomplete panicle exsertion in the cytoplasmic male sterile lines. the unexserted spikelets which are left inside the flag leaf sheath remain unfertile. this research was focu...

Several aspects of the viewing situation affect the ability to determine heading from optical flow. These include the amount of depth variation and number of texture elements in the scene, the location and amount of the visual field stimulated, and the position of the focus of expansion within the stimulus. Without a quantification of the discrimination information provided by the stimuli prese...

Stochastic topological models, and hidden Markov models in particular, are a useful tool for robotic navigation planning. In previous work we have shown how weak odometric data can be used to improve learning overcoming the common problems of standard Baum-Welch algorithm. Odometric typically contain directional information, which imposes two difficulties: First, cyclicity requires use special ...
