[edit] 2012-07-09 :: Sharon Hsiao Thesis Defence: Navigation Support and Social Visualization for Personalized E-Learning

A large number of educational resources is now made available on the Web to support both regular classroom learning and online learning. However, the abundance of available content produced at least two problems: how to help students to find the most appropriate resources and how to engage them into using these resources and benefit from them. Personalized and social learning have been suggested as potential ways to address these problems.

This work attempts to combine the ideas of personalized and social learning by providing navigation support through an open social student modeling visualization. A series of classroom studies exploited the idea of the approach and revealed promising results, which demonstrated the personalized guidance and social visualization combined helped students to find the most relevant resources of parameterized self-assessment questions for Java programming. Thus, this dissertation extend the approach to a larger collection of learning objects for cross content navigation and verify its capability of supporting social visualization for personalized E-Learning.

The study results confirm that working with the non-mandatory system, students enhanced the learning quality in increasing their motivation and engagement. They successfully achieved better learning results. Meanwhile, incorporating a mixed collection of content in the open social student modeling visualizations effectively led the students to work at the right level of questions. Both strong and weak student worked with the appropriate levels of questions for their readiness accordingly and yielded a consistent performance across all three levels of complexities. Additionally, providing a more realistic content collection on the navigation supported open social student modeling visualizations results in a uniform performance in the group. The classroom study revealed a clear pattern of social guidance, where the stronger students left the traces for weaker ones to follow. The subjective evaluation confirms the design of the interface in terms of the content organization. Students’ positive responses also compliment the objective system usage data.

[edit] 2011-11-30 :: Sergey Sosnovsky Thesis Defence: Ontology-Based Open-Corpus Personalization for E-Learning

Conventional closed-corpus adaptive information systems control limited sets of documents in fixed subject domains and cannot provide access to the content outside the system. Such restrictions contradict the requirements of today, when most of the information systems are implemented in the open document space of WWW and are expected to operate on the open-corpus content. In order to maintain personalized access to open-corpus documents, an adaptive system should be able to model the documents and the relations between the documents and the domain knowledge automatically and dynamically. This dissertation explores the problem of open-corpus personalization and semantic modeling of open-corpus content in the context of e-Learning. Information on WWW is not without structure. Many collections of online instructional material (tutorials, electronic books, digital libraries, etc.) have been provided with implicit knowledge models encoded in form of tables of content, indexes, headers of chapters, links between pages, and different styles of text fragments. The main dissertation approach tries to leverage this layer of hidden semantics by extracting and representing it as coarse-grained models of collections. A central domain ontology is used to maintain overlay modeling of studentsÕ knowledge and serves as a reference point for multiple collections of external instructional material. In order to establish the link between the ontology and the open-corpus content models a special ontology mapping algorithm has been developed. The proposed approach has been applied in the Ontology-based Open-corpus Personalization Service (OOPS) that recommends and adaptively annotates online reading material. The domain of Java programming has been chosen for the proof-of-concept implementation. A controlled experiment has been organized to evaluate the developed adaptive system and the proposed approach overall. The results of the evaluation have demonstrated several significant learning effects of the implemented open-corpus personalization. The analysis of log-based data has also shown that the open-corpus version of the system is capable of providing personalization of similar quality to the close-corpus one. Such results indicate that the proposed approach supports fully-scale open-corpus personalization for e-Learning. Further research is required to verify if the approach remains effective in other subject domains and with other types of instructional content.

[edit] 2011-07-15 :: Denis Parra earns a James Chen Best Student paper award in UMAP 2011

In the last conference of User Modeling, Adaptation and Personalization (UMAP 2011) Denis Parra won one of the 2 James Chen Best Student paper awards for his paper Walk The Talk: Analyzing the relation between implicit and explicit feedback for preference elicitation that he co-authored with Dr. Xavier Amatriain. In this paper, the authors present a study on the music domain with users, which results leads them to create a regression model that maps implicit information (such as playcounts and how recently a user listened to albums) with explicit information in the form of ratings. More details in the conference proceedings in Springer. Denis is the third PAWS Lab member to receive this prestigious award. Prior to that, Rosta Farzan and Michael Yudelson won this award at earlier User Modeling conferences. Rosta also won another James Chen award at Adaptive Hypermedia conference.

[edit] 2010-12-15 :: Peter received Google grant to work on Personalized Social Systems for Local Communities

The grant will support our efforts to increase user participation in social systems designed for local communities. In the course of the project will explore two innovative ideas for increasing participation. The first idea is to provide access to information “beyond the desktop,” by adding a mobile location-based interface to access information. This will increase both the number of active users and the volume of their contributions. The second idea is to provide personalized access to information to increase the chance to gather relevant information. This work will be based on two existing social systems that were developed and maintained by PAWs lab: the CoMeT system for sharing information about research talks at Carnegie Mellon and University of Pittsburgh and Eventur, a social system for recommending cultural events in the Pittsburgh area.

[edit] 2010-09-17 :: Michael Yudelson's Thesis Defence: Providing Service-Based Personalization In An Adaptive Hypermedia System

The dissertation proposes a novel way of speeding the development of new adaptive hypermedia systems. The gist of the approach is to extract the adaptation functionality out of the adaptive hypermedia system, encapsulate it into a standalone system, and offer adaptation as a service to the client applications. Such a standalone adaptation provider reduces the development of adaptation functionality to configuration and compliance and as a result creates new adaptive systems faster and helps serve larger user populations with adaptively accessible content.

ETD is accessible worldwide from the online library catalog of the University of Pittsburgh (link).
