• Analyzing Information Credibility in Microblogs In this study, we conducted a controlled large-scale
user experiment to find and evaluate different cues in information credibility assessment in microblogs.
We showed how perceived credibility can varies based on different cue setup.
• Deconstructing Information Credibility on Twitter Conducted a study of two collections of tweets on
a similar topic and time frame for predicting information credibility. Analyzed the underlying context
and the credibility construct that can imply significantly different models for predicting information
credibility.
• Ambient/Interactive Data Visualization Interactive visualizations that serves as a conduit of emotional stream between the media—collective intelligence or dynamics of users on any kind of virtual
community—and individuals.
• Modeling Topic Specific Credibility in Twitter Proposed three computational models for recommending
credible topic-specific information in online social network(Twitter). Conducted an evaluation on 5
topic specific data sets mined from Twitter API, with specific focus on a data set of 40K users who
tweeted about the topic “Libya”.
• Interactive Interfaces for Complex Network Analysis Implemented a module that retrieves and processes tweets for an interactive data visualization framework. Users can interact with the framework
for understanding big social data at a glance.
• Real Time Hand Pose Recognition with Depth Sensors for Mixed Reality Interfaces
Presented a
method for predicting articulated hand poses in real-time with a single depth camera, such as the
Kinect, for the purpose of interaction in a Mixed Reality environment and for studying the effects of
realistic and non-realistic articulated hand models in a Mixed Reality Simulator.
• WiGis (Web-based Interactive Graph Interfaces) and KDD Project Developed modules in a novel
data visualization framework(WiGis) that retrieve, process and visualize information from various
sources(RDF, HTML, Social Network, etc.).
• A Step Towards Marker-less Augmented Reality and Tracking Implemented a real-time augmented
reality application using any pattern/object of choice based on SURF feature extraction, matching and
homography.
• A Framework for Modeling Trust in Collaborative Ontologies Proposed a novel approach in a collaborative semantic web context with trust and credibility models. Adopted three major variablesTrust,
Credibility and Expertise and developed a trust model to show trustworthiness of the provenance of
web ontologies

• Exploring Social Graph with Facebook and Twitter API Implemented an interactive data visualization application using ActionScript. Visualized social structure with Twitter API in 2-D and 3-D
graphs/vectors.
