Integrating Bottom-up and Top-down Processing in Active Dendrites

| The classical view of information processing in the cortex is that of a bottom-up process in a feed-forward hierarchy. However there is psychophysical, anatomical and physiological evidence that top-down eeects play a crucial role in the processing of input stimuli. Hardly anything is known about the neural mechanisms underlying these effects. Here we investigate a physiologically inspired mo...

FaceTag: Integrating Bottom-up and Top-down Classification

Facetag is a working prototype of a semantic collaborative tagging tool conceived for bookmarking information architecture resources. It aims to show how the widespread homogeneous and flat keywords' space of tags can be effectively mixed with a richer faceted classification scheme to improve the “information scent” and “berrypicking” capabilities of the system. The additional semantic structur...

Integrating Bottom-Up and Top-Down Analysis For Intelligent Hypertext

The range of hypertext systems continues to expand, from custom-tailored closed systems to dynamic, distributed, and open systems like the World-Wide Web (WWW). The shift from closed to open systems results in a corresponding decrease in the effectiveness of metrics and techniques for providing intelligent hypertext to users. Essentially, the locus of control shifts away from developers towards...
