This page is a quick overview of the systems developed at PAWS lab.
Adaptive Document Visualization - ADVISE
ADVISE 2D
Two dimensional document visualization based on inter-document similarities. The locations of the documents on the 2D space are determined by their similarities to another documents and users can visually see the relationships of the documents based on their contents.
ADVISE 3D
Three dimensional visualization of documents based on similarities. By adding one more dimension to 2D visualization, users are able to explore the document space more easily and access each document.
ADVISE VIBE (or Adaptive VIBE)
|
|
Two dimensional visualization based on POIs(Point Of Interest, or concepts) and document similarities. The position of the documents are calculated by their relationships with each POI.

CUMULATE
CUMULATE is a centralized user modeling server built for the ADAPT2 architecture. It is mainly targeted at providing user modeling support for adaptive educational hypermedia (AEH) systems. CUMULATE maintains as set of overlay models of stidents' knowledge. It uses several techniques for computing student models, including: thresholded averaging, asymptotic user knowledge assessment, time-spent-reading.

PERSEUS
|
|
PERSEUS is a Personalization Service Engine. It provides adaptive support for non-personalized (educational) hypermedia systems by abstracting content presentation/aggregation from user modeling. PERSEUS protocols are based on RDF and RSS 1.0. Although, PERSEUS was initially developed for ADAPT2 framework, its data model permits seamless support of any other hypermedia application. Currently PERSEUS provides social navigation, topic-based navigation, concept-based navigation, and adaptive filtering techniques. (more)
