This paper aims at designing and constructing an ontology, representing and allowing Vietnamese folk dances annotation. An effective approach proposed is based on movement analysis. It is possible to divide Vietnamese folk dances into basic units, then movement phrases, movement primitives and dance poses. Studying deeply Vietnamese folk dances features and characteristics allows to find out 5 different types of relationships between main dance components. Typical relationships could be written in the form of logical predicates. For enriching ontologies, a formal encoding of the ontology expertise knowledge in the domain is performed by DL-Lite. The paper uses OWL-2 for building, organizing and visualizing ontologies. A case study-Mo folk dance with a knowledge base, is structured simply but effectively, with reasoning in DL-Lite and answering queries in SPARQL. © 2018 IEEE.

In this paper, we proposed an in-vehicle haptic navigation system to overcome some limitations of current in-vehicle navigation aid systems. The haptic interface using vibrotactile signals with a 5-by-5 tactor array was installed on the back of the chair. To evaluate the effectiveness of the proposed system in various cognitive load conditions, we implemented a visual search experiment using a flicker paradigm. Sixteen participants were recruited to evaluate the proposed haptic navigation system. The two independent variables were validity (valid cue, invalid cue, and no cueing) and cognitive load levels (high and low) of search tasks. Despite of the cognitive load levels, the valid cue conditions elicited shorter response times than invalid cue and no cueing conditions. The result strongly supports the effectiveness of the proposed in-vehicle navigation systems. © 2012 Springer science+Business Media.

We describe progress using a user-centered design process to migrate a family therapy game to a web-based therapist tool, called FamilySense, that supports therapists creating part of the therapeutic game. Using cards with questions about players' daily life and alternative answers considering their cultural context, the game gives parent and child awareness of each other. Online design of different elements for the board, cards and communication provide an effective online therapy tool. Four user-centered design process stages are presented including: design strategies, design questions, stakeholders, prototype and evaluation for each stage. The process has been successful for the migration, achieving an online game environment that shows strong potential for a family therapy tool. © 2010 Copyright is held by the author/owner(s).

Population aging resulting from demographic changes requires some challenging decisions and necessary steps to be taken by different stakeholders to manage current and future demand for assistance and support. The consequences of population aging can be mitigated to some extent by assisting technologies that can support the autonomous living of older individuals and persons in need of care in their private environments as long as possible. A variety of technical solutions are already available on the market, but privacy protection is a serious, often neglected, issue when using such (assisting) technology. Thus, privacy needs to be thoroughly taken under consideration in this context. In a three-year project PAAL (‘Privacy-Aware and Acceptable Lifelogging Services for Older and Frail People’), researchers from different disciplines, such as law, rehabilitation, human-computer interaction, and computer science, investigated the phenomenon of privacy when using assistive lifelogging technologies. In concrete terms, the concept of Privacy by Design was realized using two exemplary lifelogging applications in private and professional environments. A user-centered empirical approach was applied to the lifelogging technologies, investigating the perceptions and attitudes of (older) users with different health-related and biographical profiles. The knowledge gained through the interdisciplinary collaboration can improve the implementation and optimization of assistive applications. In this paper, partners of the PAAL project present insights gained from their cross-national, interdisciplinary work regarding privacy-aware and acceptable lifelogging technologies. © 2022, The Author(s).

This study investigates the effectiveness of the application of Virtual Reality Training (VRT) in the treatment of Communication Apprehension (CA). The participants were thirty undergraduate volunteer students enrolled at the university level. Virtual reality software and hardware were used to create a virtual auditorium scene for this training. Over five sessions, participants were subjected to virtual public speaking scenarios of varying intensity. Subjective Units of Disturbance (SUD) scale was used to measure the participants' anxiety levels. The average level of anxiety reported during post-test was significantly less than that of the pre-test. The preliminary results indicated that VRT could be used as an effective method for reducing CA in clients and allow them to become involved in discussions and presentations more comfortably.

Many failures in long-term collaboration occur because of a lack of activity awareness. Activity awareness is a broad concept that involves awareness of synchronous and asynchronous interactions over extended time periods. We describe a procedure to evaluate activity awareness and collaborative activities in a controlled setting. The activities used are modeled on real-world collaborations documented earlier in a field study. We developed an experimental method to study these activity awareness problems in the laboratory. Participants worked on a simulated long-term project in the laboratory over multiple experimental sessions with a confederate, who partially scripted activities and probes. We present evidence showing that this method represents a valid model of real collaboration, based on participants' active engagement, lively negotiation, and awareness difficulties. We found that having the ability to define, reproduce, and systematically manipulate collaborative situations allowed us to assess the effect of realistic conditions on activity awareness in remote collaboration.

Recognizing a piece of writing as a poem or prose is usually easy for the majority of people;however, only specialists can determine which meter a poem belongs to. In this paper, we build Recurrent Neural Network (RNN) models that can classify poems according to their meters from plain text. The input text is encoded at the character level and directly fed to the models without feature handcrafting. This is a step forward for machine understanding and synthesis of languages in general, and Arabic language in particular. Among the 16 poem meters of Arabic and the 4 meters of English the networks were able to correctly classify poem with an overall accuracy of 96.38% and 82.31% respectively. The poem datasets used to conduct this research were massive, over 1.5 million of verses, and were crawled from different nontechnical sources, almost Arabic and English literature sites, and in different heterogeneous and unstructured formats. These datasets are now made publicly available in clean, structured, and documented format for other future research. To the best of the authors' knowledge, this research is the first to address classifying poem meters in a machine learnin g approach, in general, and in RNN featureless based approach, in particular. In addition, the dataset is the first publicly available dataset ready for the purpose of future computational research. Copyright © 2019, The Authors. All rights reserved.

We investigate cognitive factors that are predictive of learning gains when students learn to solve equations by teaching a synthetic peer, called SimStudent. Previous empirical studies showed that prior knowledge is strongly predictive of post-test scores. However, in a recent study in the Philippines that replicated our previous study in the USA, there were students with low priorknowledge who tutored their SimStudent better than other equally low prior students. In this paper, we analyze both process data (tutoring interactions) and outcome data (test scores) to understand what makes learning by teaching more effective. The results imply a presence of individual behavioral differences beyond the difference in the prior knowledge that might have affected SimStudent's learning, which in turn had non-trivial influence on tutor learning.

Focus in natural language processing is used to keep track of the attentional space of the participants in the dialogue. Graphical interfaces have still to benefit from the use of this level of communication. We discuss a graphical interface counter part called a focus space. Focus spaces can be used to combine multiple interaction styles (e.g. natural language with graphical pointing). We describe how a specific theory of discourse structure and focus space can be applied to graphical interfaces. The attentional space is maintained automatically by the system, and can be used by the software under program control. An example is provided showing how the attentional space can be used. © 1992 ACM.

Generating high-coverage semantic orientation lexicons from overtly marked words and a thesaurus

Sentiment analysis often relies on a semantic orientation lexicon of positive and negative words. A number of approaches have been proposed for creating such lexicons, but they tend to be computationally expensive, and usually rely on significant manual annotation and large corpora. Most of these methods use WordNet. In contrast, we propose a simple approach to generate a high-coverage semantic orientation lexicon, which includes both individual words and multi-word expressions, using only a Roget-like thesaurus and a handful of affixes. Further, the lexicon has properties that support the Polyanna Hypothesis. Using the General Inquirer as gold standard, we show that our lexicon has 14 percentage points more correct entries than the leading WordNet-based high-coverage lexicon (SentiWordNet). In an extrinsic evaluation, we obtain significantly higher performance in determining phrase polarity using our thesaurus-based lexicon than with any other. Additionally, we explore the use of visualization techniques to gain insight into the our algorithm beyond the evaluations mentioned above. © 2009 ACL and AFNLP.
