AdVisE (Adaptive Document Visualization for Education)
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
Relevance-based visualization of educational documents based on re-implementation of VIBE, a document visualization method based on similarities between documents and POIs (Points Of Interests) developed by Molde College and School of Information Sciences, University of Pittsburgh.

Conference Navigator 3
|
|
Conference Navigator 3 (CN3) is a personal conference scheduling tool with social linking and recommendation features. Users can control access to their information in the CN3 system and link their account with third party academic and non-academic social networks such as linkedIn, Facebook, citeulike, or Mendeley. Our main goal is to enhance attendees' experience at the conferences, and also investigate the mechanisms that drives attendees to engage in their research community. (visit Conference Navigator 3)

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 a set of overlay models of students' knowledge. It uses several techniques for computing student models, including thresholded averaging, asymptotic user knowledge assessment, time-spent-reading.

Eventur
|
|
This project is to recommend interesting information using the combined technology of collaborative filtering and trust-based human network. This system is to overcome the emerging problems regarding collaborative filtering recommendations and to investigate how the information propagation is affected by trust among people. (more)
|
JavaGuide
|
|
JavaGuide is a personalized front-end for QuizJET developed by PAWS Lab (Hsiao, 2010). Java Guide collects student performance data sent by QuizJET to the activity storage, determines student current level of knowledge for multiple topics and concepts of Java programming language, and use it to provide adaptive guidance to the questions that are most appropriate for a specific student given the course goals and current state of knowledge.. (more)

Knowledge Sea II
|
|
Knowledge Sea II is an extension of Knowledge Sea project that is designed to help users navigate from lectures to relevant online tutorials in a map-based horizontal navigation format. The most important feature of Knowledge Sea is facilitating the navigation through providing traffic and annotation based social navigation support. (more)
|
Knowledge Tree
|
|
Knowledge Tree is a link aggregating portal. It presents content structured according to the folder-document paradigm. Knowledge Tree provides authentication and authorization and implements a simplified form of access control. It supports collaborative authoring and social annotation. (more)
|
KnowledgeZoom
|
|
KnowledgeZoom is an exam preparation system with zoomable open student model showing student level of knowledge for hierarchy of Java programming concepts. KnowledgeZoom allows students to find gaps in their knowledge and access learning content that helps to bridge these gaps. ==> more

Mastery Grids
|
|
Mastery Grids is our latest implementation of Open Social Learner Modeling (OSLM). It is both an innovative Open Social Learner Model Interface and an adaptive E-learning platform with integrated functionalities enabling multi-facet social comparison, open learner modeling, and adaptive navigation support to access multiple kinds of smart learning content. Mastery Grids is supported by adaptive social learning framework Aggregate. This framework supports several kinds of open student modeling, social comparison, and recommendation. In detail, Mastery Grids presents and compares user learning progress and knowledge level using colored grids, tracks user activities with learning content, and provides flexible user-centered navigation across different content levels (e.g. topic, question) and different content types (e.g. problem, example). Our past research shows that open student modeling and social comparison effectively increases students’ performance, motivation, engagement and retention.

NameSieve
 NameSieve Named-entity Navigator |
A name-entity based news exploration and filtering system. Important named-entities extracted from the search results are provided in the "cloud" form and helps further exploration. (more)
|
NavEx - Navigation to Examples
|
|
NavEx provides adaptive guidance for accessing online interactive examples. Adaptation allows students to visualize both whether they are ready to explore certain examples and what is their progress with them. NavEx-SN (SN for social navigation) also allows students to relate their progress with the progress of the group. (more)
|
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)
