Evaluation of Automated Friend Grouping in Online Social Networks

Managing friendship relationships is challenging due to the growing number of people in online social networks (OSNs). While grouping friends sometimes mitigates this challenge, the burden of manual grouping still prevents OSNs users to create groups widely for privacy control, selective sharing and filtering. In this paper, we present an automated friend grouping tool which utilizes three different clustering algorithms to create groups from Facebook friendship networks. By conducting 18 semi-structured interviews, we investigated the advantages and disadvantages of automated friend grouping in OSNs.

CrowdBand: Crowdsourced Sound Composition
CrowdBand: Crowdsourced Sound Composition

Crowdband is an automated, crowdsourced sound composition system. Requestors use the CrowdBand interface to describe the desired result, and CrowdBand automatically partitions the job into one of three kinds of mechanical turk tasks: 1) fundamental sound provision, 2) sound assembly, and 3) sound evaluation. The crowd workers' responses demonstrated that workers who are non-musicians can design sound and create novel sound compositions through our system. We also conclucded that our system facilitates the use of common compositional techniques for musically untrained workers.

SonicShapes: Visualizing Vocal Expression
SonicShapes: Visualizing Vocal Expression

SonicShapes is a real-time tool for the analysis and visualization of vocal expression. Many researchers have investigated speech and speaker recognition; and others focused on lie detection. Yet, the analysis and visualization of vocal expression remain relatively unexplored. Given the impact that semantic literacy had on society, what could the impact of nonsemantic literacy be? We begin to explore this question, and the potential impact that real time analysis and visualization of speech could have on other domains, such as speech therapy, medicine, and the creative arts.

BEDA: Visual Analysis of Multimodal data for Longitudinal Studies
BEDA: Visual Analysis of Multimodal data for Longitudinal Studies

BEDA is a visual analytic tool that helps users explore many sessions of multimodal data that are collected from different sources (e.g., video data from a video-recorder, audio data from audio-recorder, temperature and heart rate data from sensors etc.). The tool supports visualization, synchronization, annotation, and analysis of multimodal data.

ACES Aphasia Emulation Software
ACES: Aphasia Emulation Software

We introduce a novel system and model, called Aphasia Characteristics Emulation Software (ACES), that enables users to experience the speech-distorting effects of aphasia. This model adheres to the wealth of literature in language distortions resulting from aphasia.

YouPivot: finding your digital car keys

Have you ever thought, "Where is that PDF or Website I was looking at the other day? I don't remember it's name, but I was listening to AC/DC while I was reading it." Until YouPivot, you cannot search your computer this way. YouPivot is a new search technique, grounded in cognitive psychology, that lets you search on contextual cues!

The Clotho Project
The Clotho Project: Predicting Application Utility

When using the computer, each user has some notion that "these applications are important" at a given point in time. Existing techniques fail to identify at least 57% of these applications. Our work directly associates measurable computer interaction (CPU consumption, window area, etc.) with the user’s perceived application utility/importance without identifying task.

Understanding Deja Reviewers

People who review products on the web invest considerable time in what they write. So why would someone write a review that restates earlier ones? This work is a mixed-method study of deja reviewers, latecomers who echo what other people said.

tie strength model
Predicting Tie Strength

Social media treats all users the same: trusted friend or total stranger. In reality, relationships fall everywhere along this spectrum. Our work bridges this gap between theory and practice by building a model that maps social media data to tie strength.
