This paper presents a method of using wearable accelerometers and microphones to detect instances of ad-hoc physical collaborations between members of a group. 4 people are instructed to construct a large video wall and must cooperate to complete the task. The task is loosely structured with minimal outside assistance to better reflect the ad-hoc nature of many real world construction scenarios. Audio...
The aim of this study was to investigate the impact of the cultural factors on the acquisition of second language from the subjects, selected from registered students in university of science and technology. The subjects in this study were selected from the registered students in English learning courses in university of science and technology. Sixty-nine (69) undergraduates were made up two in-tact...
Information overload is one of the most important problems in context of personalized document retrieval systems. In this paper we propose to use ontology-based user profile. Ontological structures are appropriate to represent relations between concepts in user profile. We present a method for determining user profile based on his current activities. Results obtained in experimental evaluation are...
In order to perform well, an engineer has not only to solve a task but also cope with the environment. This is very important in military operations, where underperforming might have fatal consequences. As a military academy, we have developed ten coping strategies that we use to increase students' ability to perform in military situations. These strategies have been introduced in the education, but...
During the past two decades, event correlation has emerged as a prominent monitoring technique, and is essential for achieving better situational awareness. Since its introduction in 2001 by one of the authors of this paper, Simple Event Correlator (SEC) has become a widely used open source event correlation tool. During the last decade, a number of papers have been published that describe the use...
Professional skills are critical for success in the multidisciplinary, intercultural, and cross-functional team interactions that characterize 21st century engineering careers. Despite consensus around the need for developing professional skills, engineering programs have been struggling to define, teach, and measure those skills. This paper describes the investigation of the functioning of a group-based...
Increasing numbers of sensors are being deployed in environments to monitor our behaviours and environmental phenomena. Missing data is an inevitable problem in almost every sensorised environment, due to physical failure, poor connection, or dislodgement. This results in an incomplete view of the real-world, leading to poor prediction and consequently, degraded quality of system services. This paper...
In order to investigate what type of experiences of robots influences negative attitudes toward them, an online survey (N = 1,200) was conducted in Japan, by using the Negative Attitudes toward Robots Scale (NARS). The results suggested that (1) there were almost no strong relationships between types of robot experiences and gender, and age, (2) the correlations between negative attitudes toward robots...
Current research environments are witnessing high enormities of presentations occurring in different sessions at academic conferences. This situation makes it difficult for researchers (especially juniors) to attend the right presentation session(s) for effective collaboration. In this paper, we propose an innovative venue recommendation algorithm to enhance smart conference participation. Our proposed...
Word sense induction (WSI) is the problem of automatic identification of word senses given the corpus. This paper presents a method for solving WSI problem based on the context clustering approach. The idea behind this approach is that similar contexts indicate similar meanings. Specifically, we have successfully applied Correlated Topic Model (CTM) to partition contexts of a word into clusters, each...
We address the relation between persuasion and virality in social networks and provide preliminary findings based on a Digg dataset. In particular we want to understand whether a content categorized as persuasive (according to various metrics) can be categorized as viral as well. Results show that the persuasive properties of a content are related to its virality in different ways. These findings...
In this paper, we address invariant scene classification from images. We propose a novel descriptor based on the statistical characterization of the spatial patterns formed by elementary objects in images. Elementary objects are defined from a tree of shapes of the topology map of the image and each object is characterized by shape context feature vector. Viewing the set of elementary objects as a...
We discuss the use of the PLEX playful experience model a system to introduce games design aspects into alternative application and product domains. We report an exploratory study to relate the relationships between playful experiences and real world values and personalities. The method led to a prototype model of playful experiences associated with values and personality based motivations, emotions...
Poorly-chosen identifiers have been reported in the literature as misleading and increasing the program comprehension effort. Identifiers are composed of terms, which can be dictionary words, acronyms, contractions, or simple strings. We conjecture that the use of identical terms in different contexts may increase the risk of faults. We investigate our conjecture using a measure combining term entropy...
A key principle when performing research studies is that of randomisation, in order to counter any effects that the ordering of tasks, elements, subjects, etc. may have on the dependent variables. When performing requirements prioritisation, it is not always possible (e.g., because of how prioritisation methods are constructed) or even desirable to randomise all requirements before prioritising them...
Translation Memory (TM) consists of a collection of previously translated units of text that may prove useful in the translation of new text. The main problem faced by translators who wish to take advantage of TM is that, although search tools do exist, there is no standardized way of effectively ranking search results. This paper proposes a method for effectively ranking TM search results together...
In smart living spaces, a reliable context-aware application must adapt to the variable environment and should function to complete the user's requirements. Therefore, if a context-aware application is to achieve the user's requirements smoothly, it must understand the environment status according to trustworthy context information. However, the context information influenced by the environment status...
