The influence of rhythmic and spectro-timbral musical features on gait-related movement

2017

Music makes us move, and humans have the universal tendency to synchronise their movements to music. This phenomenon has been used in music therapy to help people with movement disorders regain control over their movements. Rhythmic auditory stimulation has shown promising results in gait rehabilitation in various clinical populations. In healthy populations, various differences have been found between movement while walking to musical and metronome stimuli in terms of stride length. However, insufficient research has been conducted concerning the musical features that could evoke this difference, and which gait-related movements might change under the influence of music. The aim of this mo…

The Pursuit of Happiness in Music: Retrieving Valence with Contextual Music Descriptors

2009

In the study of music emotions, Valence is usually referred to as one of the dimensions of the circumplex model of emotions that describes music appraisal of happiness, whose scale goes from sad to happy. Nevertheless, related literature shows that Valence is known as being particularly difficult to be predicted by a computational model. As Valence is a contextual music feature, it is assumed here that its prediction should also require contextual music descriptors in its predicting model. This work describes the usage of eight contextual (also known as higher-level) descriptors, previously developed by us, to calculate happiness in music. Each of these descriptors was independently tested …

Project report : Methodology for terminology harmonisation

2020

A common understanding of language and concepts used is essential for any meaningful communication. For large rescue operations effective communication is crucial to save lives. Such operations can require cooperation among first responders from several sectors with a different understanding of terms and concepts. Redningshåndboka (the National Rescue handbook) provides a common glossary for use across all sectors for their communications in training and practice. However, today each sector maintains their own glossaries, acronyms and jargon, causing potential misunderstandings in joint operations. In this report we propose a way to apply the Norwegian Public Management Standard from the No…

Enhancing Privacy and Authorization Control Scalability in the Grid through Ontologies

2009

The use of data Grids for sharing relevant data has proven to be successful in many research disciplines. However, the use of these environments when personal data are involved (such as in health) is reduced due to its lack of trust. There are many approaches that provide encrypted storages and key shares to prevent the access from unauthorized users. However, these approaches are additional layers that should be managed along with the authorization policies. We present in this paper a privacy-enhancing technique that uses encryption and relates to the structure of the data and their organizations, providing a natural way to propagate authorization and also a framework that fits with many u…

Hints from the Crowd: A Novel NoSQL Database

2013

The crowd can be an incredible source of information. In particular, this is true for reviews about products of any kind, freely provided by customers through specialized web sites. In other words, they are social knowledge, that can be exploited by other customers. The Hints From the Crowd HFC prototype, presented in this paper, is a NoSQL database system for large collections of product reviews; the database is queried by expressing a natural language sentence; the result is a list of products ranked based on the relevance of reviews w.r.t. the natural language sentence. The best ranked products in the result list can be seen as the best hints for the user based on crowd opinions the revi…

Current communication technologies in language processing

2015

Even the most cutting-edge communication-mediated technology like satellite navigation for orbit positioning, pedestrian movement recognition systems based on inertial sensors, 5G systems, let alone medical devices for coordination of human organs functionality would not be invented without technologies for language processing as an information source between humans and communication systems. Regardless of the way we communicate that is via emails, website short tweets, video conferencing systems, social networking, blogs, instant messaging through websites or mobile applications, or texting only, we use a language that is processed by computer system. Thus, the keynote paper discusses lang…

Do Individual Differences in Cognition and Personality Predict Retrieval Practice Activities on MOOCs?

2020

Online quizzes building upon the principles of retrieval practice can have beneficial effects on learning, especially long-term retention. However, it is unexplored how interindividual differences in relevant background characteristics relate to retrieval practice activities in e-learning. Thus, this study sought to probe for this research question on a massive open online course (MOOC) platform where students have the optional possibility to quiz themselves on the to-be-learned materials. Altogether 105 students were assessed with a cognitive task tapping on reasoning, and two self-assessed personality measures capturing need for cognition (NFC), and grittiness (GRIT-S). Between-group anal…

A Concurrent Neural Classifier for HTML Documents Retrieval

2003

A neural based multi-agent system for automatic HTML pages retrieval is presented. The system is based on the EαNet architecture, a neural network having good generalization capabilities and able to learn the activation function of its hidden units. The starting hypothesis is that the HTML pages are stored in networked repositories. The system goal is to retrieve documents satisfying a user query and belonging to a given class (i.e. documents containing the word “football” and talking about “Sports”). The system is composed by three interacting agents: the EαNet Neural Classifier Mobile Agent, the Query Agent, and the Locator Agent. The whole system was successfully implemented exploiting t…

Privacy preserving via tree augmented naïve Bayesian classifier in multimedia database

2011

International audience; In this paper, we propose a novel technique for privacy preserving in multimedia databases. Our technique is based on a multimedia co-occurrence matrix and a tree augmented naive Bayesian classifier (TAN) to detect possible data associations making confidential multimedia objects at risk.
