PotenziAAL

Potential and Limits of Present-day Robotics in Ambient Assisted Living

The central aim of the study is the realistic presentation of the potential of AAL Robotics, based on the analysis of parameters drawn from user needs, technical readiness, and existing business models. Instead of compiling yet another collection of individual solutions and projects, the PotenziAAL Study will aggregate existing knowledge gained from analysis of secondary sources with knowledge generated from primary sources such as expert interviews, a workshop and user focus groups in order to achieve a comprehensive picture of the state of the art in AAL Robotics and its future potential. The study will develop categories and criteria in order to foster exact characterization, comparability and quality assurance in AAL Robotics.

Cognitive-emotive Robotics for Supporting Autobiographic Storytelling

The aim of the project is the development of a virtual agent that interactively supports older persons in the narration of autobiographic stories, from listener feedback to raw transcription.

Tapping Friend

An interactive exhibit on synchronization and cooperation between humans and a virtual partner

TAPPING FRIEND is an interactive science game for everyone between 6 and 99 years and is aimed to provide a playful experience of synchronization and cooperation between one or two humans and a virtual partner – the maestro. The players tap in time with the maestro on little drums and the system provides immediate feedback on their synchronization success by showing their taps relative to the maestro’s taps and by counting the taps that were on time and the taps that were too early or too late. The aim of the game is to achieve as many on-time taps as possible.

FemSMA

Automated, gender-sensitive approaches as a means to support social media analyses in Social Sciences reseach.

The FemSMA project aims at the development of automatic methods to determine the gender of the author of a given user-created social media posting (e.g. Tweets, blog or internet forum entries). The approach is motivated by recent developments in the social sciences, as well as market and opinion research, which increasingly consider social media platforms as a valuable source of data, especially for trend and sentiment analyses. Current instruments for social media analysis are incapable of providing gender-aware information regarding the topics, products or (political) programmes under investigation. This deficit, as well as the associated lack of orientation towards active demand, will be countered effectively in FemSMA.

Preventing Hubness in Music Information Retrieval

he so-called “hubness” phenomenon is a general problem of machine learning in high dimensional data spaces. Hubs are data points which keep appearing unwontedly often in nearest neighbor lists of many other data points. This effect is particularly problematic in algorithms for similarity search, as the same “similar” objects are found over and over again. But it has also adverse effects for the many machine learning algorithms that make use of distance information. The effect has been shown to be a natural consequence of high dimensionality and as such is yet another aspect of the curse of dimensionality. The main goal of this project was to conduct an in-depth study of the hubness problem in the context of MIR.

CYBEREMOTIONS

Collective Emotions in Cyberspace

CYBEREMOTIONS is a European IP (Large Scale Integrating Project) which focuses on the role of collective emotions in creating, forming and breaking-up e-communities. Understanding these phenomena is important in view of the growing role of ICT-mediated social interactions and some specific features of e-communities. The challenge of this interdisciplinary project is to combine psychological models of emotional interactions and algorithmic methods for detection and classification of human emotions in the Internet with probabilistic models of complex systems and data driven simulations based on heterogeneous emotionally-reacting agents.

MIReS

Roadmap for Music Information ReSearch

MIReS was an EU FP7-funded 18-month project focusing on the future impact of music technology research on academia and industry. The project created a research roadmap of MIR field, by expanding its context and addressing challenges such as multimodal information, multiculturalism and multidisciplinarity.

MLT4MLV

Machine Learning Techniques for Modeling of Language Varieties

Language varieties are a primary means of expressing a person's social affiliation and identity. Hence, computer systems that can adapt to the user by displaying a familiar socio-cultural identity are expected to raise the acceptance within certain contexts and target groups dramatically. However, current systems are far from achieving the fidelity required for realization of these benefits. For example, promising early results have been obtained in the context of speech synthesis through localized pronunciation, but it is clear that language variety is a multi-faceted concept that involves deviations from standard language on various linguistic levels. Our goal is to develop algorithmic methods that are capable of capturing and reproducing all major idiosyncrasies displayed by a language variety, be they syntactic, lexical or phonetic in nature. Conceptually, part of this task can be understood as a machine translation problem, which is, however, characterized by unique properties.

Quiew

Multidomainfähiges Online-Bewertungs- und Feedbacksystem

Quiew (quick review) ist ein Forschungsprojekt zur Entwicklung eines innovativen Online-Bewertungs- und Feedbacksystems für Produkte, Dienstleistungen und andere Objekte. Basierend auf der aus der Markt- und Konsumentenpsychologie stammenden Methode des Assoziationsgeflechts nach Kirchler und De Rosa (1996) wird ein computationelles System entwickelt zur automatischen Analyse und Gruppierung von sprachlichen Äußerungen (assoziativen Feedbacks), die zur Bewertung von Produkten, Diesntleistungen etc. abgegeben wurden.
